Summary of the Invention

Problems to be Solved by the Invention

[0005] Hotel guests may leave something behind in their rooms. Such forgotten items (lost items) are often discovered by the room cleaners. The cleaners are required to register the information of the discovered lost items in the system or report them to the administrator. However, requiring such work from the cleaners increases their burden.

[0006] Furthermore, Patent Document 1 merely discloses a lost property management system that can reduce the burden of lost property management tasks on facility staff and enable space-saving in lost property storage areas. Therefore, applying the technology disclosed in Patent Document 1 will not solve the above problems.

Embodiments for Carrying Out the Invention

[0015] First, an overview of one embodiment will be described. The reference numerals in the drawings attached to this overview are provided for convenience as examples to aid understanding, and this overview is not intended to be limiting in any way. Furthermore, unless otherwise specified, the blocks shown in each drawing represent functional units, not hardware units. The connecting lines between blocks in each drawing include both bidirectional and unidirectional lines. Unidirectional arrows schematically indicate the flow of the main signal (data) and do not exclude bidirectional flow. In this specification and in the drawings, elements that can be similarly described are given the same reference numerals to avoid redundant explanation.

[0016] A server device 100 according to one embodiment includes an acquisition means 101 and a control means 102 (see Figure 1). The acquisition means 101 acquires information about the location where a hotel cleaning staff member begins cleaning from a cleaning staff terminal held by the cleaning staff member (step S1 in Figure 2). The control means 102 receives image data of the lost item found by the cleaning staff member from the cleaning staff terminal before receiving notification from the cleaning staff terminal that cleaning of that location is complete (step S2). When the control means 102 receives image data from the cleaning staff terminal, it stores information about the location where the cleaning staff member began cleaning as the location where the lost item was found in a database (step S3). For example, in step S2, the timing of receiving image data of the lost item found by the cleaning staff member from the cleaning staff terminal is not limited to before receiving notification from the cleaning staff terminal that cleaning of the guest room is complete, but may be at any time.

[0017] When the server device 100 receives notification from a cleaning staff member that cleaning has begun on a designated area (e.g., a guest room), it treats the server device 100 as if the cleaning staff member is currently cleaning that guest room. When the server device 100 receives image data of a lost item from a cleaning staff member's terminal, it determines that the lost item was found in the guest room being cleaned. The server device 100 sets the guest room being cleaned as the location where the lost item was found and stores it in a predetermined database. In other words, the registration and management of the lost item is completed by the cleaning staff member taking a photograph of the lost item they found. As a result, the workload on the hotel cleaning staff member who finds the lost item is reduced.

[0018] Specific embodiments will be described in more detail below with reference to the drawings.

[0019] [First Embodiment] The first embodiment will be described in more detail with reference to the drawings.

[0020] [System Configuration] Figure 3 is a diagram showing an example of the schematic configuration of an information processing system according to the embodiment of the present disclosure. As shown in Figure 3, the information processing system includes a server device 10.

[0021] The server device 10 performs the main operations of accommodation facilities such as hotels. Specifically, the server device 10 controls room reservations, check-in and check-out procedures for guests, concierge services, and room cleaning management.

[0022] The server device 10 may be installed within the hotel, or it may be installed on a network (on the cloud).

[0023] As shown in Figure 3, hotel cleaning staff carry cleaning staff terminals 20. The cleaning staff use the cleaning staff terminals 20 to obtain various information from the server device 10 and input various information to the server device 10.

[0024] Furthermore, hotel terminals 30 are installed at the hotel front desk and other locations. Hotel employees use the hotel terminals 30 to perform front desk duties and other tasks.

[0025] The devices shown in Figure 3 are interconnected. Specifically, the server device 10, the cleaning staff terminal 20, and the hotel terminal 30 are connected by wired or wireless communication means and are configured to communicate with each other.

[0026] The configuration of the information processing system shown in Figure 3 is illustrative and not intended to limit its configuration. For example, the system may include multiple server devices 10. Load balancing and redundancy may be achieved by using multiple server devices 10.

[0027] [General operation] Next, we will describe the general operation of the information processing system according to the first embodiment.

[0028] <Application Installation> The cleaning staff terminal 20 has the "hotel application" installed. For example, a cleaning staff member operates the cleaning staff terminal 20 to launch the hotel application. The cleaning staff terminal 20 (hotel application) accesses the server device 10. Through the hotel application, the cleaning staff member retrieves information from the server device 10 and inputs information into the server device 10. For example, the functions of the "hotel application" include displaying the cleaning schedule received from the server device 10, inputting information about the room or area to be cleaned, inputting completion of cleaning, and taking photos of lost and found items and sending the photos.

[0029] <Room cleaning> The server device 10 determines the room cleaning schedule periodically or at predetermined intervals. For example, the server device 10 determines the room cleaning schedule at the hotel's predetermined check-out time (for example, 10:00 a.m.).

[0030] For example, the server device 10 generates a cleaning schedule for rooms that have already been checked out (rooms whose status is "before cleaning"). For example, it generates a cleaning schedule based on a request from a guest.

[0031] The server device 10 notifies the cleaning staff of the generated cleaning schedule. Specifically, the server device 10 sends a "cleaning schedule notification" to the cleaning staff terminal 20 carried by the cleaning staff (see Figure 4).

[0032] The cleaning staff terminal 20 displays the cleaning schedule included in the cleaning schedule notification to the cleaning staff. For example, upon receiving the cleaning schedule notification, the cleaning staff terminal 20 displays a screen as shown in Figure 5. The cleaning staff cleans the guest rooms according to the schedule (order) instructed by the server device 10.

[0033] Upon arriving in front of the designated room, the cleaning staff notifies the server device 10 of the room information to be cleaned. Specifically, the cleaning staff terminal 20 displays a GUI (Graphical User Interface) as shown in Figure 6, depending on the cleaning staff's operation. The cleaning staff inputs the room number of the room to be cleaned into the cleaning staff terminal 20. For example, the cleaning staff may input the room number of the room to be cleaned into the cleaning staff terminal 20 by taking a photograph of the room number. For example, the cleaning staff may input the room number of the room to be cleaned into the cleaning staff terminal 20 by obtaining location information using the cleaning staff terminal 20.

[0034] Furthermore, the areas that cleaning staff clean are not limited to guest rooms; corridors, lobbies, front desks, elevator halls, restaurants, banquet halls / conference rooms, gyms, gift shops, smoking areas, restrooms, stairwells, etc., may also be included in the cleaning. Cleaning staff only need to input information about the area (location) to be cleaned into the server device 10 via the cleaning staff terminal 20.

[0035] Upon obtaining the room number, the cleaning staff terminal 20 notifies the server device 10 of the obtained room number. The cleaning staff terminal 20 then sends a "cleaning commencement notification" including the room number to the server device 10 (see Figure 7).

[0036] When the server device 10 receives a cleaning start notification, it recognizes that the room with the room number included in the notification is being cleaned. The server device 10 sets the status of the room corresponding to the notified room number to "cleaning in progress".

[0037] Once the cleaning of a guest room is complete, the cleaning staff notifies the server device 10 of this. For example, the cleaning staff terminal 20 displays a GUI as shown in Figure 8 in response to the cleaning staff's operation. When the cleaning staff terminal 20 inputs that the cleaning of a guest room has been completed (when the OK button is pressed), it notifies the server device 10 of the guest room number of the room that has been cleaned. Specifically, the cleaning staff terminal 20 sends a "cleaning completion notification" including the guest room number to the server device 10 (see Figure 9). For example, the cleaning staff's operation may also be done by voice input or gesture input. For example, the cleaning staff may input that cleaning has been completed by sending a photo of the area they have cleaned after cleaning.

[0038] When the server device 10 receives a cleaning completion notification, it understands that cleaning has been completed for the room corresponding to the room number included in the notification. The server device 10 sets the status of the room corresponding to the notified room number to "cleaned".

[0039] <Management of lost and found items> Cleaning staff may find lost items (forgotten items) while cleaning guest rooms. In this case, the cleaning staff operates the cleaning staff terminal 20 to photograph the found lost item. For example, the cleaning staff terminal 20 acquires image data of the lost item using a GUI as shown in Figure 10.

[0040] Upon acquiring image data, the cleaning staff terminal 20 sends a "lost item found notification" containing the image data to the server device 10 (see Figure 11).

[0041] Upon receiving a notification of lost property discovery, the server device 10 extracts an image of the lost property (hereinafter referred to as the lost property image) from the image data included in the notification. Furthermore, the server device 10 obtains information regarding the characteristics of the lost property by analyzing the lost property image. For example, if the server device 10 cannot obtain sufficient information regarding the characteristics of the lost property from the image data sent from the cleaning staff terminal 20, it can instruct the cleaning staff terminal 20 to resend the image data.

[0042] For example, the server device 10 acquires information such as "long wallet" and "red" as characteristics of the lost item. The server device 10 treats the characteristics of the lost item as "tag information." That is, the server device 10 assigns tag information to the lost item (image of the lost item).

[0043] The server device 10 stores the lost item image, the date and time the lost item was found, the location where the lost item was found (the room number of the room being cleaned by the cleaning staff), and tag information in association with each other.

[0044] The cleaning staff member who finds the lost item places it in a designated bag or similar container. Furthermore, the cleaning staff member attaches a label to the bag containing the lost item, indicating the date and time of discovery, the location of discovery, etc. The cleaning staff member then carries the bag containing the lost item to a designated location. For example, the label may be printed by the cleaning staff member's terminal 20. For example, the label may be automatically printed by the server device 10 through image analysis of the lost item. For example, from a privacy perspective, it is also possible to manage information about the lost item by coding it. For example, the server device 10 may use QR (Quick Response) codes or barcodes.

[0045] <Searching for lost items> The server device 10 is equipped with a function that allows hotel staff to search for lost items. Specifically, hotel staff will search for lost items in response to inquiries from guests (including guests who have already checked out). Hotel staff will access the server device 10 by operating the hotel terminal 30. The server device 10 will accept requests to search for lost items on a designated web page or the like and display the results.

[0046] For example, a hotel employee inputs the name of the lost item, the date (or period) the item was found, and the location (such as the room number) as search keywords into the server device 10 via the hotel terminal 30. Alternatively, the hotel employee inputs the characteristics of the lost item (tag information) as search keywords into the server device 10. For example, the server device 10 may generate search keywords by analyzing inquiries from guests via telephone (voice) or email (text).

[0047] The server device 10 displays the search results on the hotel terminal 30. For example, the server device 10 displays a screen on the hotel terminal 30 as shown in Figure 12.

[0048] Next, we will describe the details of each device included in the information processing system according to the first embodiment.

[0049] [Server equipment] Figure 13 is a diagram showing an example of the processing configuration (processing module) of the server device 10 according to the embodiment disclosed herein. Referring to Figure 13, the server device 10 comprises a communication control unit 201, a room cleaning control unit 202, a lost and found control unit 203, a search control unit 204, and a storage unit 205.

[0050] The communication control unit 201 is a means for controlling communication with other devices. For example, the communication control unit 201 receives data (packets) from the cleaning staff terminal 20. The communication control unit 201 also transmits data to the cleaning staff terminal 20. The communication control unit 201 passes the data received from other devices to other processing modules. The communication control unit 201 transmits the data acquired from other processing modules to other devices. In this way, other processing modules send and receive data with other devices via the communication control unit 201. The communication control unit 201 has the function of a receiving unit that receives data from other devices and the function of a transmitting unit that transmits data to other devices.

[0051] The room cleaning control unit 202 is a means for controlling the cleaning of a guest room after a guest has checked out. For example, the room cleaning control unit 202 generates a cleaning schedule for the guest room periodically or at predetermined intervals. For example, when a predetermined check-out time arrives, the room cleaning control unit 202 generates a cleaning schedule.

[0052] Here, the reservation status and occupancy status of each hotel room are stored in the room status management database (see Figure 14). Entries with a circle (○) in the reservation status field of the room status management database indicate that the room is reserved.

[0053] Furthermore, the room status management database shown in Figure 14 is an example and is not intended to limit the items to be stored. For example, the room status management database stores the guest's (booked guest's) name, gender, date of birth, address, contact information (telephone number, email address), etc.

[0054] The guest room status management database is managed by hotel staff. When a hotel staff member receives a reservation from a customer, they operate the hotel terminal 30 to access the server device 10. The hotel staff member inputs information about the received reservation into the server device 10. The server device 10 reflects the information obtained from the hotel staff member in the reservation status field and other fields of the guest room status management database.

[0055] Alternatively, hotel staff input information (room number) of the room where a guest has checked in or checked out into the server device 10. The server device 10 reflects the information obtained from the hotel staff into the status field of the room status management database. Specifically, when a guest checks in, the server device 10 sets the status of the corresponding room to "occupied". When a guest checks out, the server device 10 sets the status of the corresponding room to "before cleaning".

[0056] Alternatively, the server device 10 may provide a webpage or the like that accepts accommodation reservations and reflect the customer's reservation information in the room status management database. Alternatively, the server device 10 may perform check-in and check-out procedures for guests and reflect the results in the room status management database.

[0057] Detailed explanations regarding the management of reservation and room availability are omitted because they are outside the scope of this disclosure.

[0058] Figure 15 is a flowchart showing an example of the operation of the guest room cleaning control unit 202 according to the embodiment disclosed herein. The operation of the guest room cleaning control unit 202 will be explained with reference to Figure 15.

[0059] The room cleaning control unit 202 refers to the room status management database and extracts rooms whose status is set to "before cleaning". The room cleaning control unit 202 then sets the extracted rooms as targets for generating a cleaning schedule.

[0060] The guest room cleaning control unit 202 generates a cleaning schedule based on various rules and policies (step S101).

[0061] For example, the room cleaning control unit 202 generates a cleaning schedule that prioritizes rooms that are fully booked for that day. For instance, if rooms 201, 301, and 401 are to be cleaned, and there are same-day bookings for rooms 201 and 401, the room cleaning control unit 202 generates a cleaning schedule that cleans rooms 201, 401, and 301 in that order.

[0062] Alternatively, the room cleaning control unit 202 may generate a cleaning schedule that allows cleaning staff to efficiently patrol the rooms to be cleaned. Specifically, the room cleaning control unit 202 uses information about the hotel's internal structure (location of each room, number and location of elevators) to calculate a travel route that allows cleaning staff to reach each room in the shortest possible time.

[0063] For example, the room cleaning control unit 202 determines the travel route so that the total travel distance for the cleaning staff is the shortest. For example, the room cleaning control unit 202 extracts the room on the highest floor among the rooms to be cleaned. Then, the room cleaning control unit 202 determines that the room furthest from the elevator among the extracted rooms is the first to be visited.

[0064] Furthermore, the room cleaning control unit 202 extracts the room on the lowest floor from among the multiple rooms to be cleaned. Then, the room cleaning control unit 202 determines the room furthest from the elevator among the extracted rooms as the final destination. For example, the room cleaning control unit 202 sets the first destination as the starting point and the last destination as the ending point and generates a travel route (cleaning schedule) using Dijkstra's algorithm.

[0065] The room cleaning control unit 202 transmits the generated cleaning schedule to the cleaning staff terminal 20 held by the cleaning staff. The room cleaning control unit 202 also transmits a "cleaning schedule notification" containing the cleaning schedule to the cleaning staff terminal 20 (step S102).

[0066] The room cleaning control unit 202 receives a cleaning start notification from the cleaning staff terminal 20. The room cleaning control unit 202 sets the status of the room corresponding to the room number included in the notification to "Cleaning in progress" (step S103).

[0067] The room cleaning control unit 202 receives a cleaning completion notification from the cleaning staff terminal 20. The room cleaning control unit 202 sets the status of the room corresponding to the room number included in the notification to "cleaned" (step S104).

[0068] Thus, the room cleaning control unit 202 has a function as an acquisition means that acquires information (for example, room number) of the room that the hotel cleaning staff member is about to start cleaning from the cleaning staff terminal 20 held by the cleaning staff member.

[0069] The lost and found control unit 203 is a means for performing control over lost items found by cleaning staff. The lost and found control unit 203 processes lost item discovery notifications received from the cleaning staff terminal 20.

[0070] The lost and found control unit 203 may receive image data from the cleaning staff terminal 20 showing the lost item found by the cleaning staff member before receiving notification from the cleaning staff terminal 20 that cleaning of the room has been completed. Upon receiving the image data showing the lost item, the lost and found control unit 203 has a function as a control means that stores information (room number) of the room in which the cleaning staff member began cleaning as the location where the lost item was found in a predetermined database.

[0071] Figure 16 is a flowchart showing an example of the operation of the lost property control unit 203 according to the embodiment disclosed herein. The operation of the lost property control unit 203 will be explained with reference to Figure 16.

[0072] When the cleaning staff terminal 20 receives a notification of lost item discovery, the lost item control unit 203 extracts an image of the lost item (lost item image) from the image data included in the notification (step S201). For example, the lost item control unit 203 extracts the lost item image by cropping the image along the outline of an object that is visible near the center of the image data.

[0073] Alternatively, the lost and found control unit 203 may extract images of lost items by inputting image data into a pre-prepared learning model or a generative AI (Artificial Intelligence) model.

[0074] The lost item control unit 203 obtains the characteristics of the lost item by analyzing the extracted image of the lost item. More specifically, the lost item control unit 203 assigns tag information to the lost item (step S202). For example, the lost item control unit 203 assigns tag information to the lost item using a learning model.

[0075] The learning model is obtained through machine learning using a large amount of training data in which image data (image data of lost items) are tagged with labels (tag information; for example, long wallet, red). Any algorithm such as support vector machines, boosting, or neural networks can be used to generate the learning model. Note that the above-mentioned algorithms such as support vector machines can be publicly known techniques, so their explanation will be omitted.

[0076] The lost and found control unit 203 obtains tag information by inputting the image of the lost item into a learning model.

[0077] The lost and found control unit 203 stores information about the found lost item in the lost and found management database (stores lost and found information; step S203).

[0078] Specifically, the lost and found control unit 203 stores the lost and found image, the date and time the lost and found item was discovered (the date and time the lost and found notification was received), the location where the lost and found item was discovered, and tag information in the lost and found management database (see Figure 17). Note that the lost and found management database shown in Figure 17 is an example and is not intended to limit the items to be stored.

[0079] The lost and found control unit 203 then refers to the room status management database and identifies entries where the status field is set to "Cleaning in progress". The lost and found control unit 203 determines that the lost item has been found in the room corresponding to the room number of the identified entry. In the example in Figure 14, it is determined that the lost item has been found in room number 201.

[0080] In this way, the lost and found control unit 203 extracts an image of the lost item from the image data received from the cleaning staff terminal 20, and obtains information about the characteristics of the lost item from the extracted image of the lost item. The lost and found control unit 203 stores the obtained information about the characteristics of the lost item in the lost and found management database. The lost and found control unit 203 obtains information about the characteristics of the lost item (tag information) using a learning model.

[0081] The search control unit 204 is a means for performing control related to the search for lost items. Specifically, the search control unit 204 uses search keywords obtained from the user to search for information about lost items stored in the lost item management database.

[0082] The search control unit 204 provides a lost and found search function on a designated webpage when a user (for example, a hotel employee) operates the hotel terminal 30 and accesses that webpage.

[0083] For example, the search control unit 204 displays a GUI as shown in Figure 12 on the hotel terminal 30. When a user enters a search keyword (when the search button is pressed), the search control unit 204 searches the lost and found database using that search keyword.

[0084] For example, if a date is obtained as the search keyword, the search control unit 204 refers to the discovery date and time field in the lost property management database and identifies the entry for the lost property that was discovered on the date specified by the search keyword.

[0085] Alternatively, if a location (room number) is obtained as a search keyword, the search control unit 204 refers to the discovery location field in the lost and found management database and identifies the entry for the lost item found at the location (room) specified by the search keyword.

[0086] Alternatively, if the name or characteristics of a lost item are obtained as search keywords, the search control unit 204 refers to the tag information field in the lost item management database and identifies an entry for a lost item that has the characteristics specified by the search keywords.

[0087] Here, the search control unit 204 may use a learning model to absorb variations in the spelling of search keywords. For example, if the search keyword is "wallet," the search control unit 204 may also use words such as "long wallet," "bi-fold wallet," and "wallet" that can be inferred from the keyword "wallet" as search keywords and search the lost and found database.

[0088] The search control unit 204 displays the information obtained from the entries identified by the search using the search keywords (at least one entry) as search results on the hotel terminal 30. For example, as shown in Figure 12, the search control unit 204 displays the discovery date and time, discovery location, and image of the lost item that matches the search keywords on the hotel terminal 30. Alternatively, the search control unit 204 may also display the tag information of the identified entries along with the discovery date and time.

[0089] The memory unit 205 is a means for storing information necessary for the operation of the server device 10.

[0090] [Cleaning staff terminal] Figure 18 is a diagram showing an example of the processing configuration (processing module) of a cleaning worker terminal 20 according to the embodiment disclosed herein. Referring to Figure 18, the cleaning worker terminal 20 comprises a communication control unit 301, a cleaning control unit 302, a lost and found control unit 303, and a storage unit 304.

[0091] The communication control unit 301 is a means for controlling communication with other devices. For example, the communication control unit 301 receives data (packets) from the server device 10. The communication control unit 301 also transmits data to the server device 10. The communication control unit 301 passes the data received from other devices to other processing modules. The communication control unit 301 transmits the data acquired from other processing modules to other devices. In this way, other processing modules send and receive data with other devices via the communication control unit 301. The communication control unit 301 has the function of a receiving unit that receives data from other devices and the function of a transmitting unit that transmits data to other devices.

[0092] The cleaning control unit 302 is a means for performing control related to the cleaning of guest rooms.

[0093] When the cleaning control unit 302 receives a cleaning schedule notification from the server device 10, it displays the cleaning schedule for the guest rooms included in the notification. For example, the cleaning control unit 302 displays a GUI as shown in Figure 5.

[0094] When a user (cleaner) performs a predetermined operation, the cleaning control unit 302 obtains the room number of the room that the user is to begin cleaning. For example, the cleaning control unit 302 obtains the room number of the room that the cleaner is to begin cleaning using a GUI as shown in Figure 6.

[0095] The cleaning control unit 302 sends a cleaning start notification, including the acquired room number, to the server device 10.

[0096] In response to a predetermined operation by the cleaning staff, the cleaning control unit 302 transmits a message to the server device 10 indicating that the cleaning staff has completed cleaning the guest room. For example, the cleaning control unit 302 displays a GUI that acknowledges the completion of room cleaning while displaying the room number obtained from the cleaning staff (the room number of the guest room entered at the start of cleaning). For example, the cleaning control unit 302 detects that room cleaning is complete using a GUI as shown in Figure 8.

[0097] The cleaning control unit 302 sends a cleaning completion notification to the server device 10, which includes the room number of the room that has been cleaned.

[0098] The lost and found control unit 303 is a means for controlling lost items found by cleaning staff.

[0099] In response to a predetermined operation by the cleaning staff, the lost and found control unit 303 displays a GUI for the user (cleaning staff) to photograph the lost item. For example, the lost and found control unit 303 acquires image data of the lost item using a GUI like the one shown in Figure 10.

[0100] The lost and found control unit 303 sends a lost and found notification, including the acquired image data, to the server device 10.

[0101] The memory unit 304 is a means for storing information necessary for the operation of the cleaning staff terminal 20.

[0102] As described above, the cleaning staff terminal 20 comprises a first control means (cleaning control unit 302) and a second control means (lost and found control unit 303). The first control means obtains information from the cleaning staff about the room in which the cleaning staff will begin cleaning and transmits the obtained room information to the server device. The second control means transmits image data of the lost item found by the cleaning staff to the server device.

[0103] <Hotel Terminal> Examples of hotel terminals 30 include mobile devices such as smartphones, cell phones, game consoles, and tablets, as well as computers (personal computers, laptops). Hotel terminal 30 can be any device or equipment as long as it can receive operations from reservation requesters and cleaning staff and communicate with the server device 10, etc.

[0104] Next, a modified example of the first embodiment will be described.

[0105] <Example 1> The information processing system according to the first embodiment may include a function to identify the owner of the lost item.

[0106] In this case, the cleaner takes a photograph of the room before entering and actually starting to clean. The cleaner takes a photograph of the room from a predetermined location (for example, the room's entrance). The cleaner operates the cleaner's terminal 20 to take a photograph of the room before cleaning.

[0107] The cleaning staff terminal 20 sends a "pre-cleaning image notification" to the server device 10, which includes the acquired image data and the room number (the room number of the room to be cleaned).

[0108] The lost and found control unit 203 of the server device 10 temporarily stores the image data included in the notification in association with the room number. The lost and found control unit 203 stores the image included in the pre-cleaning image notification as the "pre-cleaning image".

[0109] After cleaning a guest room, the cleaning staff will take a photograph of the room after cleaning. The cleaning staff will take the photograph from the same position from which they took the photograph when they started cleaning the room (for example, the room entrance).

[0110] The cleaning staff terminal 20 sends a "post-cleaning image notification" to the server device 10, which includes the acquired image data and the room number (the room number of the room that has been cleaned).

[0111] The lost and found control unit 203 stores the image data included in the notification in the room status management database. The lost and found control unit 203 stores the image data taken after the room has been cleaned as "post-cleaning image" in the entry corresponding to the room number included in the post-cleaning image notification.

[0112] Through the operation of the server device 10, images of the room after cleaning (post-cleaning images) are stored in the room status management database. The lost and found control unit 203 may either overwrite the post-cleaning images stored in the room status management database or add new post-cleaning images to the room status management database each time it receives a new post-cleaning image notification.

[0113] The lost and found control unit 203 determines whether or not a lost item exists in the guest room when it receives a pre-cleaning image notification. Specifically, the lost and found control unit 203 reads the post-cleaning image of the guest room corresponding to the guest room number included in the pre-cleaning image notification from the guest room status management database. The lost and found control unit 203 then determines whether or not there is a difference between the read post-cleaning image and the pre-cleaning image included in the pre-cleaning image notification.

[0114] For example, the lost and found control unit 203 inputs two images into a learning model (generative AI model) and instructs it to detect the presence or absence of an object that is not present in the image after cleaning but is present in the image before cleaning.

[0115] If the learning model determines that no such object exists, the lost and found control unit 203 does not perform any special processing. In this case, it is determined that no lost items exist in the guest room before cleaning.

[0116] If the learning model determines that such an object exists, the lost and found control unit 203 determines that there is a high probability that the object is a lost item belonging to the guest who stayed immediately before (the guest who checked out immediately before). In this case, the lost and found control unit 203 instructs the learning model to extract an image of the object (lost and found image) from the pre-cleaning image.

[0117] The lost and found control unit 203 stores information about the detected lost item in the lost and found management database. At the same time, the lost and found control unit 203 accesses the room status management database and retrieves information about the guest who stayed in the room with the room number included in the pre-cleaning image notification (e.g., name, address, contact information). The lost and found control unit 203 also obtains tag information from the lost item image.

[0118] The lost and found control unit 203 stores in the lost and found management database images of the lost item, the date and time the lost item was found, the location where it was found, and tag information, as well as guest information (name, contact information, etc.) read from the guest room status management database.

[0119] Alternatively, the lost and found control unit 203 may notify hotel staff or others when a lost item is detected. For example, the lost and found control unit 203 may notify hotel staff via the hotel terminal 30 that a lost item has been detected.

[0120] Specifically, the lost and found control unit 203 transmits the lost and found image, the date and time the lost and found item was discovered, the location and tag information, and guest information (name, contact information, etc.) read from the room status management database to the hotel terminal 30. The hotel terminal 30 then notifies hotel staff stationed at the front desk of the received information.

[0121] Hotel staff who receive notification will contact the guest if necessary to inform them that the lost item has been found.

[0122] Furthermore, if a lost item is detected, the lost item control unit 203 may notify the cleaning staff (the cleaning staff member who is about to begin cleaning the guest room). The lost item control unit 203 transmits the extracted image of the lost item to the cleaning staff terminal 20 and instructs the cleaning staff member to retrieve the lost item corresponding to the image.

[0123] Thus, the lost and found control unit 203 may receive a post-cleaning image from the cleaning staff terminal 20 showing the interior of a guest room after the cleaning staff has finished cleaning, and store the received post-cleaning image. When the lost and found control unit 203 receives a pre-cleaning image from the cleaning staff terminal 20 showing the interior of a guest room before the cleaning staff begins cleaning, it may determine whether or not there is a lost item in the guest room that the cleaning staff is about to start cleaning, based on the stored post-cleaning image and the received pre-cleaning image. If there is a lost item, the lost and found control unit 203 may notify hotel staff or others accordingly.

[0124] <Modification 2> Before lost items are registered in the lost and found database, guests may inquire about them with the hotel. In this case, the hotel employee who receives the inquiry may use the hotel terminal 30 to notify the server device 10 of the inquiry.

[0125] Specifically, the hotel terminal 30 transmits the name and contact information of the inquirer (the guest who has checked out), as well as information about the lost item provided by the inquirer (the name and characteristics of the lost item; for example, a red long wallet), etc., to the server device 10.

[0126] When the lost and found control unit 203 obtains information about the inquirer and the lost item from the hotel terminal 30, it stores the obtained information in the storage unit 205.

[0127] When the lost item finder receives a notification from the cleaning staff terminal 20, the lost item control unit 203 processes the notification. Furthermore, the lost item control unit 203 determines whether or not an inquiry regarding the lost item found by the cleaning staff has already been made.

[0128] Specifically, the lost and found control unit 203 performs the above determination using the stored information about the lost item and information obtained from the image of the lost item (e.g., tag information). For example, the lost and found control unit 203 sets the characteristics of a lost item found by a cleaning staff member (e.g., a long wallet) as the search target and the characteristics of a lost item inquired about by a guest who has checked out (e.g., a wallet) as the search target, and determines whether or not there has been an inquiry regarding the lost item found by the cleaning staff member.

[0129] If the lost item inquired about matches (or is highly likely to match) the lost item found by the cleaning staff, the lost item control unit 203 notifies the hotel staff accordingly. For example, the lost item control unit 203 transmits the stored information of the inquirer, the characteristics of the lost item (tag information), and an image of the lost item to the hotel terminal 30. The hotel terminal 30 displays the received information.

[0130] Hotel staff who see the displayed information (notified information) will, if necessary, contact the inquirer to inform them that the lost item has been found.

[0131] Thus, when the lost and found control unit 203 receives image data of the lost item from the cleaning staff terminal 20, it may determine whether or not the lost item found by the cleaning staff is the same item that was inquired about by a guest who has checked out.

[0132] <Variation 3> The server device 10 may automatically create a report document (a document to be submitted to the police) regarding the found lost item. For example, the server device 10 may generate the report document regarding the lost item in response to instructions from a hotel employee or the like. Alternatively, the server device 10 may generate the report document at the time the lost item is found.

[0133] In this case, the lost and found control unit 203 sets the hotel name as the finder and generates a report document by transcribing the date and time of discovery, the location of discovery, and information about the found lost item (e.g., tag information; e.g., long wallet, red) into a predetermined format. The lost and found control unit 203 may print the generated report document or transmit it to the hotel terminal 30 or the like.

[0134] As described above, when the server device 10 according to the first embodiment receives a cleaning start notification from the cleaning staff terminal 20, the cleaning staff determines that they are cleaning the room corresponding to the room number included in the notification. When the server device 10 receives image data of a lost item from the cleaning staff terminal 20 held by the cleaning staff, it treats the lost item as having been found in the room being cleaned. The server device 10 sets the room being cleaned as the location where the lost item was found and stores it in the lost item management database. In other words, the registration and management of the lost item is completed when the cleaning staff photographs the lost item they found. In other words, in the information processing system according to the first embodiment, the cleaning management system used by cleaning staff and the lost and found management system are linked, and by uploading photos to the room information on the system, the room and date and time in which the lost item was found are recorded. As a result, the workload of hotel cleaning staff who find lost items is reduced, or the lost and found registration process is made more efficient.

[0135] Furthermore, the server device 10 can absorb variations in search keywords through its learning model and present appropriate search results to the user. For example, even if search keywords such as "wallet with sequins" or "sparkly wallet" are entered, the server device 10 can present appropriate search results.

[0136] Next, we will describe the hardware of each device that makes up the information processing system. Figure 19 shows an example of the hardware configuration of server device 10.

[0137] The server device 10 can be configured using an information processing device (a so-called computer), and has the configuration illustrated in Figure 19. For example, the server device 10 includes a processor 311, memory 312, input / output interface 313, and communication interface 314, etc. The components of the processor 311, etc., are connected by an internal bus or the like and are configured to communicate with each other.

[0138] However, the configuration shown in Figure 19 is not intended to limit the hardware configuration of the server device 10. The server device 10 may include hardware not shown, and it may not have to have an input / output interface 313 if necessary. Also, the number of processors 311 etc. included in the server device 10 is not intended to be limited to the example in Figure 19; for example, multiple processors 311 may be included in the server device 10.

[0139] The processor 311 is a programmable device such as a CPU (Central Processing Unit), MPU (Micro Processing Unit), or DSP (Digital Signal Processor). Alternatively, the processor 311 may be a device such as an FPGA (Field Programmable Gate Array) or ASIC (Application Specific Integrated Circuit). The processor 311 executes various programs, including an operating system (OS).

[0140] Memory 312 includes RAM (Random Access Memory), ROM (Read Only Memory), HDD (Hard Disk Drive), SSD (Solid State Drive), etc. Memory 312 stores the OS program, application programs, and various data.

[0141] The input / output interface 313 is an interface for a display device or input device (not shown). The display device is, for example, a liquid crystal display. The input device is, for example, a device that accepts user input such as a keyboard or mouse.

[0142] The communication interface 314 is a circuit, module, etc., that communicates with other devices. For example, the communication interface 314 includes a NIC (Network Interface Card), etc.

[0143] The functions of the server device 10 are realized by various processing modules. These processing modules are realized, for example, by the processor 311 executing a program stored in memory 312. The program can also be recorded on a computer-readable storage medium. The storage medium can be a non-transitory material such as semiconductor memory, hard disk, magnetic recording medium, or optical recording medium. In other words, the present invention can also be embodied as a computer program product. Furthermore, the program can be downloaded via a network or updated using the storage medium on which the program is stored. Moreover, the processing module may be realized by a semiconductor chip.

[0144] Furthermore, the cleaning staff terminal 20, etc., can also be configured using an information processing device, similar to the server device 10, and since its basic hardware configuration is no different from that of the server device 10, a detailed explanation will be omitted.

[0145] The server device 10, which is an information processing device, is equipped with a computer, and its functions can be realized by having the computer execute a program. Furthermore, the server device 10 executes a control method for the server device 10 using this program.

[0146] [Differentiation] The configuration and operation of the information processing system described in the above embodiment are illustrative examples and are not intended to limit the system configuration.

[0147] In the above embodiment, the configuration and operation of the information processing system were explained using the example of a cleaning staff member cleaning a guest room. However, the cleaning staff member may also clean locations other than guest rooms (for example, conference rooms, banquet halls, etc.). Even in this case, the cleaning staff member operates the cleaning staff terminal 20 to input information about the location where cleaning will begin (for example, the name of the conference room) into the server device 10. If the server device 10 receives a notification of lost item found before receiving a cleaning completion notification from the cleaning staff terminal 20, it should manage the location where the cleaning staff member started cleaning as the location where the lost item was found.

[0148] The cleaning staff terminal 20 may acquire the cleaning staff's name, etc., when the hotel application is launched, etc. When the cleaning staff terminal 20 sends a lost item discovery notification, it may send the cleaning staff's name, etc., along with image data of the lost item, to the server device 10. The lost item control unit 203 of the server device 10 may store the cleaning staff's name as the finder of the lost item, along with the information of the lost item, in the lost item management database.

[0149] The server device 10 may obtain a name as a search keyword. However, in the search for lost property, it is considered that there is a high risk of misidentification if the lost property is determined solely by name. Therefore, when the server device 10 performs a search by name, it may display on the hotel terminal 30 a message indicating that the search result is highly likely to belong to the person whose name is being used.

[0150] In the above embodiment, the operation of the server device 10 was described assuming that there is one cleaning staff member responsible for cleaning the guest rooms. If there are multiple cleaning staff members, the server device 10 may assign a specific area of ​​responsibility to each of the multiple cleaning staff members and generate a cleaning schedule for each staff member. For example, the guest room cleaning control unit 202 may assign cleaning staff member A to be responsible for guest rooms on the 2nd to 4th floors, cleaning staff member B to be responsible for guest rooms on the 5th to 7th floors, and generate a cleaning schedule accordingly.

[0151] If multiple cleaning staff are responsible for cleaning the hotel, the cleaning staff terminal 20 may send information identifying the cleaning staff (e.g., name or user ID) to the server device 10 when sending notifications for cleaning start, cleaning completion, and lost item discovery. The server device 10 may use the information identifying the cleaning staff to identify the rooms that each cleaning staff member started cleaning, finished cleaning, and found lost items in.

[0152] In the above embodiment, a case was described in which the server device 10 sends a cleaning schedule notification, including the cleaning schedule, to the cleaning staff terminal 20. Instead of the notification, the server device 10 may send information about the rooms to be cleaned (room numbers of rooms whose status is "before cleaning") to the cleaning staff terminal 20. The cleaning staff terminal 20 displays the room numbers of the rooms to be cleaned that it has received. The cleaning staff decides which rooms to clean from among the displayed room numbers.

[0153] In the above embodiment, the case in which the guest room status management database and the lost and found management database are configured inside the server device 10 was described, but these databases may be built on an external database server or the like. In other words, some functions of the server device 10 may be implemented on another server. More specifically, it is sufficient that the "lost and found control unit (lost and found control means)", "search control unit (search control means)", etc. described above are implemented in any device included in the system.

[0154] The form of data transmission and reception between each device (server device 10, cleaning staff terminal 20, etc.) is not particularly limited, but the data transmitted and received between these devices may be encrypted. Image data of lost items, etc., is transmitted and received between these devices, and it is desirable that encrypted data be transmitted and received in order to properly protect this information.

[0155] In the flowcharts (sequence diagrams) used in the above description, multiple processes (processes) are shown in order, but the execution order of the processes performed in the embodiment is not limited to the order in which they are shown. In the embodiment, the order of the illustrated processes can be changed to the extent that it does not impair the content, for example, by executing each process in parallel.

[0156] The embodiments described above are explained in detail to facilitate understanding of the disclosure, and it is not intended that all the configurations described above are necessary. Furthermore, when multiple embodiments are described, each embodiment may be used individually or in combination. For example, it is possible to replace parts of the configuration of one embodiment with those of another embodiment, or to add configurations from other embodiments to the configuration of one embodiment. In addition, it is possible to add, delete, or replace parts of the configuration of one embodiment with those of another.

[0157] As described above, the industrial applicability of the present invention is clear, and it is particularly suitable for use in information processing systems that provide lost and found management services in hotels and the like.
