[Modes for carrying out the invention]

[0008] The embodiments of the analysis device, information provision system, information processing system, program, and information provision method will be described in detail below with reference to the attached drawings.

[0009] <Example System Configuration> Figure 1 is a system configuration diagram showing an example of an information processing system 100 according to an embodiment. The information processing system 100 comprises an information provision system 50 and a user terminal 40. The information provision system 50 has a document management system 10, a schedule management system 20, and an analysis device 30 that can communicate via a network N. "Communication possible" does not require constant communication; it is sufficient if communication is possible when needed. The user terminal 40 is connected to the network N in a communication-enabled manner. Note that the document management system 10 and the schedule management system 20 may be integrated into a single unit.

[0010] Network N is assumed to be a general network such as the internet. It may include LANs within a company or home, or it may include Wide Area Ethernet (registered trademark) or WANs consisting of multiple LANs. The network may be partially or entirely wireless. Wireless networks may include wireless LANs, WiMAX, and mobile phone networks such as 3G, 4G, and 5G.

[0011] The user terminal 40 is a terminal device used by users such as employees, and is a general-purpose information processing device with communication and display functions. Examples of information processing devices that can serve as user terminals 40 include PCs (Personal Computers), tablet devices, smartphones, mobile phones, and wearable PCs such as watches. Other devices with information processing functions, such as electronic whiteboards, video conferencing terminals, digital signage terminals, or car navigation systems, are also acceptable. It is anticipated that there will be multiple user terminals 40.

[0012] The document management system 10, the schedule management system 20, and the analysis device 30 are so-called server devices and have the functions of information processing devices. A server is a computer that provides files, data, etc. to other computers connected via a network. It may be called a web server, HTTP server, or WWW server. However, the document management system 10, the schedule management system 20, and the analysis device 30 do not need to be dedicated server devices; they can be general-purpose information processing devices. Since the document management system 10, the schedule management system 20, and the analysis device 30 are operated by the same or related parties, they can be the same device (one information processing device, two or more information processing devices connected by a dedicated line, the same tenant in the cloud, etc.).

[0013] The document management system 10 allows users to register document information, which is document information created by the user, via the user terminal 40, and centrally manages the use and disposal of this document information. Here, "document" refers to materials including documents. Furthermore, "document information" refers to the electronic data of materials. The document information created by the user is not limited to document information, but can include various types of information such as spreadsheet information and image information. Document information includes electronic data such as file formats such as PDF, WORD, EXCEL, PowerPoint (all trademarks or registered trademarks) and image file formats.

[0014] The schedule management system 20 manages the user's daily schedule. The schedule management system 20 registers and manages schedule information, which includes the user's appointments and the date and time of their execution, via the user terminal 40.

[0015] The analysis device 30 analyzes the correlation between document information managed by the document management system 10 and the schedule information of individual users managed by the schedule management system 20. Based on the analysis results, it provides users with document information recommended to them, tailored to their individual schedule information.

[0016] In addition, the analysis device 30 stores document information and the schedule information of individual users, and also stores the operation log information of the users on the analysis device 30.

[0017] In addition, the analysis device 30 evaluates the quality of the recommendation information based on the changes in the schedule information of the users managed by the schedule management system 20 and the browsing history (operation log information) of the recommended document information, and modifies the recommendation information based on the evaluation result.

[0018] Note that browser software operates on the user terminal 40. The analysis device 30 transmits various types of information such as recommendation information to the user terminal 40. The recommendation information is described in HTML, a script language (JavaScript: registered trademark), CSS (Cascade Style Sheet), and the like. The recommendation information may also be referred to as a web page or a web app. A web app is software or its mechanism used on a browser that operates by the cooperation of a program in a script language (for example, JavaScript (registered trademark)) operating on browser software and a program on the web server side. Note that, instead of browser software, application software having an equivalent function may operate on the user terminal 40.

[0019] <Hardware Configuration Example> Next, the hardware configurations of the document management system 10, the schedule management system 20, the analysis device 30, and the user terminal 40 in the information processing system 100 of the present embodiment will be described.

[0020] The document management system 10, the schedule management system 20, and the analysis device 30 are realized by, for example, a PC (Personal Computer) and a server which are computer systems having the hardware configuration shown in FIG. 2.

[0021] Figure 2 shows the hardware configuration diagrams for the PC and server. Here, we will describe the hardware configuration of Server 5.

[0022] As shown in Figure 2, Server 5 is built by a computer and includes a CPU (Central Processing Unit) 501, ROM (Read Only Memory) 502, RAM (Random Access Memory) 503, HD (Hard Disk) 504, HDD (Hard Disk Drive) controller 505, display 506, external device connection I / F (Interface) 508, network I / F 509, bus line 510, keyboard 511, pointing device 512, DVD-RW (Digital Versatile Disc Rewritable) drive 514, and media I / F 516.

The RAM 403 is used as the work area for the CPU 401. The EEPROM 404 reads or writes various data, such as smartphone programs, according to the control of the CPU 401. The CMOS (Complementary Metal Oxide Semiconductor) sensor 405 is a type of built-in imaging means that captures an image of a subject (mainly a self-portrait) according to the control of the CPU 401 to obtain image data. Note that it may be an imaging means such as a CCD (Charge Coupled Device) sensor instead of a CMOS sensor. The image sensor I / F 406 is a circuit that controls the driving of the CMOS sensor 405. The acceleration / direction sensor 407 is a type of sensor such as an electronic magnetic compass, gyrocompass, or acceleration sensor that detects the Earth's magnetic field. The media I / F 409 controls the reading or writing (storage) of data to or from the recording medium 408, such as flash memory. The GPS receiver 411 receives GPS signals from GPS satellites.

[0028] The smartphone 4 also includes a long-range communication circuit 412, a CMOS sensor 413, an image sensor interface 414, a microphone 415, a speaker 416, an audio input / output interface 417, a display 418, an external device connection interface 419, a short-range communication circuit 420, an antenna 420a for the short-range communication circuit 420, and a touch panel 421.

[0029] Of these, the long-range communication circuit 412 is a circuit that communicates with other devices via the network N.

[0030] Furthermore, the smartphone 4 is equipped with a bus line 410. The bus line 410 is an address bus, data bus, etc., for electrically connecting each component, such as the CPU 401 shown in Figure 3.

[0031] <Functions of the analysis device 30> Next, the functions of the analysis device 30 will be described. Various functions, as described below, are realized by a browser or application (program) installed on the analysis device 30.

[0032] Figure 4 is a functional block diagram showing the functions of the analysis device 30.

[0033] As shown in Figure 4, the analysis device 30 includes a document acquisition means 301, a schedule acquisition means 302, an information analysis means 303, and a recommendation information provision means 304.

[0034] The document acquisition means 301 acquires document information from the document management system 10.

[0035] The schedule acquisition means 302 acquires schedule information for each user from the schedule management system 20.

[0036] The information analysis means 303 analyzes the correlation between document information and schedule information.

[0037] The information analysis means 303 analyzes the correlation between strings contained in the schedule information and strings contained in the document information. Furthermore, the information analysis means 303 analyzes the correlation between strings contained in the schedule information and strings contained in the document information, and uses morphological analysis to determine whether the divided strings match, and determines the magnitude of the correlation from the strings with a high degree of match.

[0038] The recommendation information provision means 304 provides the user with recommendation information regarding document information suitable for that user, based on the analysis results of the information analysis means 303. The recommendation information may be the document information itself, or it may be the file name of the document information, a link or URL to access the document information, etc. The recommendation information provision means 304 also evaluates the quality of the recommendation information based on the search or browsing history of the document information related to the recommendation information. Furthermore, the recommendation information provision means 304 evaluates the quality of the recommendation information based on changes in the user's schedule information related to the recommendation information.

[0039] In addition, the recommendation information provision means 304 recreates the recommendation information based on the evaluation results of the quality of the recommendation information.

[0040] <Recommendation Processing Procedure> Next, we will explain the recommendation process in the information processing system 100.

[0041] Here, Figure 5 is a sequence diagram showing the procedure for recommendation processing. The processing in the information processing system 100 (document management system 10, schedule management system 20, analysis device 30) and the user terminal 40 is executed by applications installed in the information processing system 100 (document management system 10, schedule management system 20, analysis device 30) and the user terminal 40, respectively.

[0042] As shown in Figure 5, the user saves the document information created on the user terminal 40 to the document management system 10 as appropriate (step S1).

[0043] Furthermore, the user registers schedule information with the schedule management system 20 via the user terminal 40 as needed (step S2).

[0044] The document acquisition means 301 of the analysis device 30 acquires document information from the document management system 10 (step S3) and saves it (step S4).

[0045] Furthermore, the schedule acquisition means 302 of the analysis device 30 acquires schedule information for each user from the schedule management system 20 (step S5) and saves it (step S6).

[0046] Subsequently, the information analysis means 303 of the analysis device 30 analyzes the correlation between document information and schedule information (step S7).

[0047] The information analysis means 303 of the analysis device 30 performs morphological analysis on strings such as the subject of document information or the subject of schedule information as part of the correlation analysis. The information analysis means 303 of the analysis device 30 determines whether the divided strings match and determines the magnitude of the correlation from the strings with a high degree of match.

[0048] Subsequently, the information analysis means 303 of the analysis device 30 notifies the user that the correlation has been analyzed (step S8).

[0049] When a user accesses the analysis device 30 (step S9), the recommendation information providing means 304 of the analysis device 30 recommends document information that the user needs, in accordance with the schedule information, based on the results of the correlation analysis (step S10).

[0050] Here, Figure 6 shows an example of a schedule, and Figure 7 shows an example of recommendation information. As shown in Figure 6, for example, let's assume that a planning meeting for product A is registered in User A's schedule today (Monday).

[0051] In this case, the information analysis means 303 of the analysis device 30 obtains "product A" and "planning meeting" through, for example, morphological analysis, and obtains the planning meeting document for product A and the planning meeting document for another product similar to product A (for example, the planning meeting document for product B). Then, as shown in Figure 7, the recommendation information provision means 304 of the analysis device 30 provides the document information to be presented to the user, such as the planning meeting document for product A and the planning meeting document for another product similar to product A (for example, the planning meeting document for product B), as recommendation information to user A's user terminal 40. User A's user terminal 40 receives and displays the recommendation information provided by the recommendation information provision means 304 of the analysis device 30.

[0052] In the example of recommendation information shown in Figure 7, icons for today's (Monday's) recommendations, as well as icons for tomorrow's (Tuesday's) recommendations and this week's recommendations are displayed. For example, since a design meeting for product B is registered for tomorrow (Tuesday), the design document for product B will be provided as a recommendation.

[0053] Next, the user searches for and views document information within the analysis device 30 (steps S11, S12). In particular, if there is a lack of recommendation information, the user will perform a search, so the recommendation information providing means 304 of the analysis device 30 saves the user's document viewing history as an operation log when the user searches for or views document information (step S13).

[0054] Here, Figure 8 shows an example of a document viewing history. As shown in Figure 8, the document viewing history stores the date and time of access to the document information, the accessed document information, and the user who accessed it, in association with each other. In particular, the inclusion of the access date and time allows for the understanding of the relationship with the schedule information.

[0055] The recommendation information providing means 304 of the analysis device 30 analyzes the information again using the saved operation log and performs an evaluation of the quality of the recommendation information and recreates (corrects) the recommendation information (step S14).

[0056] The recommendation information providing means 304 of the analysis device 30 identifies the document information required by the schedule information, such as determining that this document information is required for this schedule information, based on a combination of the stored operation log and the schedule information of the accessed user.

[0057] For example, suppose the recommendation information provision means 304 of the analysis device 30 recommends "Product A Planning Document" to employee A and employee B. Based on the operation log shown in Figure 8, it can be seen that in the schedule information around January 12th, "Product A Planning Document" is necessary for employee A because it has been viewed, but unnecessary for employee B because it has not been viewed.

[0058] As described above, if there is no operation to view the recommended document information, the recommendation information providing means 304 of the analysis device 30 determines that the document information is not necessary for this schedule, verifies the effectiveness of the recommendation information as inappropriate, and modifies the recommendation information.

[0059] Furthermore, the recommendation information provision means 304 of the analysis device 30 updates the recommendation information based on the evaluation and recreation (correction) of the recommendation information and makes recommendations to the user (step S15).

[0060] Thus, according to this embodiment, even if there is no similar schedule in the past, it is possible to identify and present to the user documents that are highly relevant to the user's schedule content and are necessary for the user.

[0061] Furthermore, according to this embodiment, by linking the document management system 10 and the schedule management system 20, personalized documents tailored to the user are recommended, allowing the user to quickly access the document information they need and reducing the time spent searching for documents.

[0062] Furthermore, according to this embodiment, after recommending document information, the recommendation information can be modified based on the user's document viewing history.

[0063] The program executed by the analysis device 30 of this embodiment is provided as an installable or executable file recorded on a computer-readable recording medium such as a CD-ROM, flexible disk (FD), CD-R, or DVD (Digital Versatile Disc).

[0064] Furthermore, the program executed by the analysis device 30 of this embodiment may be stored on a computer connected to a network such as the Internet and provided by being downloaded via the network. Alternatively, the program executed by the analysis device 30 of this embodiment may be provided or distributed via a network such as the Internet.

[0065] Furthermore, the program executed by the analysis device 30 of this embodiment may be pre-installed and provided in ROM or the like.

[0066] The program executed by the analysis device 30 of this embodiment has a modular configuration that includes the above-described parts (document acquisition means 301, schedule acquisition means 302, information analysis means 303, and recommendation information provision means 304). In actual hardware, the CPU (processor) reads the program from the storage medium and executes it, loading the above-described parts onto the main memory, and generating the document acquisition means 301, schedule acquisition means 302, information analysis means 303, and recommendation information provision means 304 on the main memory.

[0067] Furthermore, each function of the embodiment described above (document acquisition means 301, schedule acquisition means 302, information analysis means 303, recommendation information provision means 304) can be realized by one or more processing circuits. Hereinafter, "processing circuit" in this specification includes processors programmed to execute each function by software, such as processors implemented by electronic circuits, as well as devices such as ASICs (Application Specific Integrated Circuits), DSPs (Digital Signal Processors), FPGAs (Field Programmable Gate Arrays), and conventional circuit modules designed to execute each of the functions described above.

In one embodiment, the analysis apparatus 30 includes multiple computing devices, such as a server cluster. The multiple computing devices are configured to communicate with each other via any type of communication link, including a network or shared memory, and perform the processing disclosed herein.
