Description

Technical Field

[0001] The present invention relates to the field of computer technology, and particularly to a method and system for publishing targeted information. Background Art

[0002] With the development of random computer networks, it has become possible for servers on the computer network side to send various types of information to multiple user terminal sides, and to display the received information in the applications carried on the user terminal side. In this case, a targeted publishing method is required to send targeted information to the corresponding user terminals. The targeted publishing method is a method adopted for information with the same eigenvalue published for user terminals belonging to the same type.

[0003] For example, in the online medical consultation service of computer Internet, there are many scenarios where targeted information needs to be published for user terminals used by doctors for operations, event notifications, or education and training, etc. Currently, in the process of publishing targeted information, the feature matching of information is performed according to the features of the publishing user terminals, and the matched information is used as the targeted information for publishing. For example, based on the rank, hospital, or behavior characteristics of doctors, etc., the characteristics of the user terminals used by doctors are determined, and all information is matched based on this feature, and at least one information with the highest matching degree is used as the targeted information for publishing. In this way, for different user terminals using the same application, the displayed targeted information is different.

[0004] Therefore, in order to enable the user terminal to display the targeted information most in line with the characteristics of the user terminal, it is necessary to improve the accuracy of matching. In order to improve the accuracy of matching, it is necessary to adopt a suitable matching method to achieve. Currently, there are two matching methods, which are described below respectively.

[0005] The first method: a conditional retrieval method based on an information database set in the server on the network side. This method queries the optional information list in the information database through the resource bit identifier of the displayed information, and then, for the characteristics of each information in the information list, matches the characteristics of the current user terminal one by one to determine at least one information with the highest matching degree as the targeted information. This method requires multiple feature matches, which will cause a large number of relational queries in the server on the network side, making its performance unable to be guaranteed.

[0006] The second method: adopting the caching and filtering query method. To solve the problems of the first method, after the user terminal obtains the corresponding information list according to the resource position identifier from the network-side server, it can cache it in the user terminal, and then filter and query the cached information list based on the user terminal characteristics in the local memory. After taking at least one piece of information with the highest matching degree as the targeted information, it is displayed. Although this method can avoid a large number of relationship queries in the network-side server to a certain extent, it needs to perform filtering queries locally and also needs to perform multiple feature matches, which will also cause more resource consumption of the terminal.

[0007] In summary, no matter which of the above matching methods is adopted for matching to enable the user terminal to display the targeted information that best conforms to the characteristics of the user terminal, there are a large number of filtering queries, conditional queries, or / and matching queries involved. The whole process is complex, consuming a lot of resources of the network-side server or the user terminal, resulting in resource and performance losses of the targeted information publishing system. Summary of the Invention

[0041] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0042] In the description and claims of the present invention and the above-mentioned drawings, the terms "first", "second", "third", "fourth", etc. (if any) are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0043] The technical solution of the present invention will be described in detail below with specific embodiments. The following several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0044] As can be seen from the background art, when publishing targeted information, the reasons for the complexity of the targeted information publishing process and the resource and performance losses of the targeted information publishing system are as follows: in order to obtain targeted information, multi-feature matching of information is performed using a set matching method, which will cause performance and resource losses of the system, and increase the time for publishing targeted information and the complexity of publishing targeted information.

[0045] In an embodiment of the present invention, in order to solve this problem, a first mapping relationship between the resource bit information of the resource bits for caching published information and the information identifiers of multiple pieces of information to be published, a second mapping relationship between the combination of information feature types and the information identifiers, and a third mapping relationship between the feature values of the information and the information identifiers are cached. When receiving a request from a user terminal to publish targeted information, the information identifier corresponding to the resource bit information of the requested targeted information to be published is determined according to the first mapping relationship; the combination of information feature types corresponding to each information identifier is obtained according to the second mapping relationship, and for each piece of information, based on the combination of information feature types corresponding to the information, the feature value of the user terminal sending the request is extracted; the information identifier corresponding to the user terminal feature value is determined according to the third mapping relationship, and the information with the determined information identifier is used as the targeted information and published on the resource bit of the user terminal.

[0046] In this way, since three mapping relationships are cached, the feature values of the user terminal are directly extracted according to the first two mapping relationships, and the targeted information corresponding to the user terminal feature values is determined according to the third mapping relationship. Therefore, only direct retrieval is required to obtain the targeted information, rather than implementing multi-feature matching of information, reducing the complexity of publishing targeted information and reducing the resource and performance losses of the targeted information publishing system.

[0047] That is to say, when extracting the eigenvalue of the user terminal in the embodiment of the present invention, different eigenvalue type combination models are set for different release information. After extracting the eigenvalue of the user terminal according to this model, it is then matched with the eigenvalue of the release information, thus avoiding the cumbersome process of one-to-one matching of multiple features of the user terminal with multiple features of the release information (there are multiple release information, and one-to-one matching needs to be carried out respectively), which can improve the matching speed and reduce the loss of system performance and resources.

[0048] Figure 1 FIG. 4 is a flowchart of a method for releasing targeted information provided by an embodiment of the present invention, and its specific steps include:

[0049] Step 101, cache the first mapping relationship between the resource bit information of the resource bit carrying the release information and the information identifiers of multiple release information, the second mapping relationship between the eigenvalue type combination of the information and the information identifier, and the third mapping relationship between the eigenvalue of the information and the information identifier;

[0050] Step 102, receive a request from the user terminal to release targeted information, and determine the information identifier corresponding to the resource bit information of the requested targeted information to be released according to the first mapping relationship;

[0051] Step 103, obtain the eigenvalue type combination of the information corresponding to each information identifier according to the second mapping relationship, and for each of the information, based on the eigenvalue type combination of the corresponding information, extract the eigenvalue of the user terminal that sends the request;

[0052] Step 104, determine the information identifier corresponding to the eigenvalue of the user terminal according to the third mapping relationship, and use the information with the determined information identifier as the targeted information and carry it on the resource bit of the user terminal for release.

[0053] In this method, the resource bit information of the resource bit carrying the release information includes: resource bit identifier or / and resource bit category.

[0054] In this method, the first mapping relationship between the resource bit information of the resource bit carrying the release information and the information identifiers of multiple release information includes:

[0055] Determine the topic information to be released according to the resource information of the resource bit, including topic identifier and duration;

[0056] Select the release information under the topic information, which corresponds to the information identifier of the release information.

[0057] In this way, the information that can be released under each resource bit can be accurately determined.

[0058] In this method, for the multiple release information in the first mapping relationship, cache weights are respectively set, and they are arranged in sequence based on the set cache weights;

[0059] Before extracting the feature values of the user terminal that sends the request for each of the pieces of information based on the combination of the feature types of the corresponding information, the following steps are further included:

[0060] Obtain each of the pieces of information in sequence according to the information arrangement order in the first mapping relationship.

[0061] In an embodiment of the present invention, the information may be advertising information.

[0062] In an embodiment of the present invention, the first mapping relationship, the second mapping relationship, and the third mapping relationship are cached on the server on the network side; steps 102 to 104 are implemented by the server on the network side.

[0063] In an embodiment of the present invention, the first mapping relationship, the second mapping relationship, and the third mapping relationship are cached on the user terminal; steps 102 to 104 are implemented by the user terminal.

[0064] A specific example is given to illustrate the embodiment of the present invention in detail.

[0065] In the embodiment of the present invention, different feature type combination models are first set for different release information, and then the subsequent direct retrieval of targeted information process is carried out. Figure 2 It is a schematic diagram of the feature type combination structure of the release information provided by the embodiment of the present invention. This example is described by taking the computer Internet medical online consultation service as an example, and includes:

[0066] 1) Resource position information. The resource position represents the release position of the information to be released. For example, the splash screen advertisement position on the home page of a certain application on the user terminal, the home page banner position, etc., can be uniquely identified by a resource position identifier;

[0067] 2) Release information. The release information is the content of the released information, which can be uniquely identified by an information identifier. Among them, the information can also have many classifications for different business processes, such as advertisements or product terms, etc.;

[0068] 3) The release target is the object to be delivered, that is, the specific user terminal to be delivered to. It is retrieved by defining a series of group characteristics. For example, retrieval is performed based on doctor titles, hospital grades, or / and doctor identifiers, etc. The retrieval condition is a combination of feature types, which is used to select the retrieval range.

[0069] 4) The release theme is a description of the business to which the released information belongs and can be understood as an activity of releasing information. For example, if it is planned to release a group of training advertisements for "evaluation of the quality of medical consultation services", this activity is the release theme for this time, with specific start and end times. The content of the released information is differentiated based on the doctor's department type and / or doctor's professional title difference.

[0070] After confirming the combination of feature types of the released information, the feature values of the user terminal can be extracted according to this combination, and then information identification matching can be performed based on the extracted feature values of the user terminal (matching using the third mapping relationship), so as to complete direct retrieval. Since the released information is retrieved according to many feature combinations, when the user accesses the resource position through the user terminal, it is necessary to perform retrieval based on the feature values under the combination of feature types of the information to be released at this resource position, and find the most suitable targeted information to be presented to the user at this resource position. Here, for the resource positions of the same released information, multiple pieces of information may be hit. Cache weights can also be set among multiple pieces of information, and the selected released information is determined as the targeted information for release based on the cache weights of multiple pieces of information.

[0071] When determining the targeted information through direct retrieval, it is based on the feature values under the combination of feature types of the information identification of the corresponding information in the cache. The structure of the cache is shown in Table 1:

[0072]

[0073] Table 1

[0074] The construction of the cache occurs when information is to be released. For example, when an operator wants to release information, it is necessary to maintain the cache shown in Table 1 in the user terminal or on the server on the server side. It can be seen from Table 1 that three mapping relationships are mainly maintained here. The most core one is to use the combination of feature types of the information as a feature type expression for construction and caching. When releasing information subsequently, according to the feature type expression, the features of the user terminal are parsed, and the feature values under the feature combination expression are extracted. The corresponding information identification is matched from the cache based on the obtained feature values, so that the information with the information identification is used as the targeted information.

[0075] Figure 3 The following is a flowchart of an example of a method for releasing targeted information provided by an embodiment of the present invention. Taking the information as advertisement information as an example, the specific steps include:

[0076] Setting stage: During this stage, when setting the requirements for advertising information release, a first mapping relationship between the resource position information of the resource positions for releasing advertising information and multiple information identifiers for the advertising information to be released, a second mapping relationship between the characteristic type combinations of the advertising information and the information identifiers, and a third mapping relationship between the characteristic values of the advertising information and the information identifiers are constructed.

[0077] Step 301: Operate the release system based on the targeting information.

[0078] Step 302: The operator sets the advertising information to be released.

[0079] Step 303: Build a cache for the advertising information to be released, and execute steps 304 - 306.

[0080] Step 304: Cache in the advertising information identifier list corresponding to the resource position and set the cache weight.

[0081] Step 305: Cache the characteristic type combination of the advertising information and the corresponding information identifier in the cache based on the characteristic type combination.

[0082] Step 306: Cache the characteristic value of the advertising information and the corresponding information identifier in the cache database based on the characteristic value.

[0083] Usage stage: During the usage stage, when matching the population involved in the released advertising information on the user terminal, the characteristic type combination of the target object is parsed according to the constructed characteristic type combination expression, and based on the characteristic value under the parsed characteristic type combination, the corresponding information identifier is determined, and the advertising information with this information identifier is used as the targeting information for release.

[0084] Step 307: The user accesses the resource position through the user terminal.

[0085] Step 308: Obtain the advertising information identifier list corresponding to the resource position.

[0086] Step 309: Obtain each information identifier in the advertising information identifier list, and loop in sequence according to the cache weight set for the advertising information to match the advertising information with the corresponding information identifier.

[0087] Step 310: Obtain the characteristic type combination of the advertising information from the cache database based on the characteristic type combination.

[0088] Step 311: Extract the characteristic value under the characteristic type of the user terminal based on the characteristic combination type.

[0089] Step 312: Construct the characteristic value of the information requested to be released by the user terminal.

[0090] Step 313: Match the information identifier corresponding to the eigenvalue of the user terminal request publishing information from the cache database based on eigenvalues;

[0091] Step 314: Determine whether the match is successful;

[0092] Step 315: Obtain the advertisement information with the corresponding information identifier as the targeted advertisement information and publish it.

[0093] In the embodiment of the present invention, when determining the targeted information, a feature retrieval function is set in the server or terminal on the network side. This function is actually a feature factory that can construct a feature type expression, extract the eigenvalue of the user terminal based on the constructed feature type expression, and perform subsequent matching searches in the cache based on the extracted eigenvalue of the user terminal to obtain the corresponding information identifier, and use the information with the determined information identifier as the targeted information. As Figure 4 shown, Figure 4 is a schematic diagram of the feature factory provided by the embodiment of the present invention for constructing each feature type expression.

[0094] In this way, the entire retrieval process of the embodiment of the present invention is a cache retrieval based on a key-value structure, which does not require multiple filtering, matching, and screening in the memory of the server on the network side or in the memory of the terminal, reduces the performance consumption of the terminal, saves search time and complexity, constructs and parses the feature type combination of information throughout the process, realizes logical decoupling, and facilitates unified management of information features.

[0096] The cache unit is used to cache the first mapping relationship between the resource bit information of the resource bit carrying the publishing information and multiple information identifiers of the information to be published, the second mapping relationship between the feature type combination of the information and the information identifier, and the third mapping relationship between the eigenvalue of the information and the information identifier;

[0097] The retrieval unit is used to receive the request of the user terminal to publish targeted information, determine the information identifier corresponding to the resource bit information of the requested targeted information to be published according to the first mapping relationship; obtain the feature type combination of the information corresponding to each obtained information identifier according to the second mapping relationship, and for each of the information, extract the eigenvalue of the user terminal sending the request based on the feature type combination of the corresponding information; determine the information identifier corresponding to the eigenvalue of the user terminal according to the third mapping relationship, and use the information with the determined information identifier as the targeted information and carry it on the resource bit of the user terminal for publishing.

[0099] The cache unit is further configured such that the first mapping relationship between the resource bit information of the resource bit carrying the release information in the cache and the information identifiers of multiple pieces of information to be released includes: determining the topic information to be released according to the resource information of the resource bit, including a topic identifier and a duration; and selecting the release information under the topic information, which corresponds to the information identifier of the release information.

[0100] In this system, the cache unit is further configured such that for the multiple pieces of information to be released in the first mapping relationship, cache weights are respectively set, and they are arranged in sequence based on the set cache weights;

[0101] The retrieval unit is further configured such that before extracting the user terminal feature value of the sending request based on the combination of the feature types of the corresponding information for each piece of information, it further includes: sequentially obtaining each piece of information according to the information arrangement order in the first mapping relationship.
