It should be understood that the number of terminal devices, networks, servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, servers, as desired for implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of a method for determining a target user in accordance with the present application is shown. The method for determining the target user comprises the following steps:
In this embodiment, an execution subject (e.g., a server or a terminal device shown in fig. 1) of the method for determining a target user may obtain a search log of a user to be filtered. The user to be screened may be a user who searches using a search engine. Alternatively, a time period for the filtering may be specified, for example, within the last three months, and the user to be filtered may be a user who searches using the search engine within the specified time period for the filtering.
When a user searches on the network, the search engine server may record related search data, where the search data may include a user identifier, a device identifier of an electronic device used, an IP (Internet Protocol) address for connecting to the network, search times/frequency, and the like, and may also include a query of the user used in the search, search time, a browser used in the search, and the like. Optionally, the search log may also include the geographic location of the user, e.g., the search engine may record location information of the user when the user makes a search request based on the geographic location. The search engine may generate a search log from the recorded search data and store the search log in a log file.
The executing body can take the saved search logs of a large number of users as the search logs of the users to be screened. The execution body may also send a log acquisition request to an electronic device (for example, a search engine server) storing search logs of a large number of users, and receive a search log sent by the electronic device storing the search logs of the large number of users as a search log of a user to be screened.
The search intention of the user to be screened, which executes the search operation, may be identified based on the search log obtained in step 201, so as to obtain intention information of the user to be screened. Specifically, the intent of the user to be filtered may be identified based on the user query in the search log. The identified intent information may optionally be a combination of intent words.
In some optional implementations, an NLP (Natural Language Processing) technology may be adopted to extract a search keyword from a user query as an intention word representing the user intention. In other alternative implementations, the user query may be input into the trained intent recognition model to obtain an intent recognition result corresponding to the user query. The trained intention recognition model can be obtained based on sample query training of a large amount of marked intention information, can be a model formed based on a deep neural network such as a multilayer cyclic neural network and a multilayer convolutional neural network, and can also be a model formed based on a linear classifier, a decision tree, a naive Bayes method and the like.
In some optional implementation manners of this embodiment, when identifying the search intention of the user to be filtered, the intention identification may also be performed in combination with other search data such as search time in the query of the user and search time in the search log, a browser used in the search, and the number of searches. For example, the search data may be preprocessed, converted into a set data format (e.g., vector), and then subjected to intent recognition using a machine learning model constructed based on a neural network.
After the intention information of the user to be screened is identified, the intention information of the user to be screened can be matched with the sensitive intention information in a preset sensitive intention information base. The preset sensitive intention information base may be a set of preset sensitive intention information. The sensitive intention information may be information that is a condition for filtering the target user. In practice, a user of the method for determining a target user of the present embodiment may configure a corresponding sensitive intention information base. For example, a public security department may configure some keywords, key pictures, etc. related to bad social behavior to generate a sensitive intention information base.
When the intention information of the user to be screened is matched with the sensitive intention information in the preset sensitive intention information base, whether the similarity between the intention information of the user to be screened and the sensitive intention information reaches a preset threshold value or not can be judged, and if the similarity between the intention information of the user to be screened and the sensitive intention information reaches the preset threshold value, the fact that the intention information of the user to be screened and the sensitive intention information are successfully matched can be determined. When calculating the similarity, the data processing method may be adopted to convert the two into mathematical expressions with the same dimension, for example, the intention information in the form of a picture may be processed to obtain a feature matrix or a feature vector of an image, or the intention information in the form of a text may be processed to obtain a text feature vector. In some embodiments, intention analysis can be performed on intention information and sensitive intention information of a user to be screened, and semantic similarity of the intention information and the sensitive intention information can be calculated; or the intention information to be matched can be vectorized by adopting a word to vector (text vectorization) mode, and the similarity between the intention information of the user to be screened and the sensitive intention information is calculated by adopting a similarity measurement mode such as the pre-similarity.
Alternatively, the sensitive intention information base may be a combination of one or more of the following: a sensitive intention word library, a sensitive picture library and a sensitive audio resource library. In a specific implementation manner, the sensitive intention information base may be a sensitive intention word base, and the intention information of the user to be screened, which is identified by the execution main body, may be an intention word or a combination of the intention words. When the identified intention information of the user to be screened is matched with the sensitive intention information in the preset sensitive intention information base, whether the identified intention words or intention word combinations of the user to be screened contain sensitive intention words or near-meaning words of the sensitive intention words in the preset sensitive intention word base can be judged, and whether the intention information of the user to be screened is matched with the sensitive intention information in the preset sensitive intention information base or not can be judged.
And 203, determining a target user from the users to be screened according to the matching result of the intention information of the users to be screened and the sensitive intention information in the preset sensitive intention information base.
In this embodiment, a user to be screened corresponding to intention information that is successfully matched with the sensitive intention information in the preset sensitive intention information library may be taken as a target user, and specifically, a user to be screened corresponding to intention information whose similarity to the sensitive intention information in the preset sensitive intention information library reaches a preset threshold may be taken as a target user, so that the target user with a sensitive intention may be found.
According to the method for determining the target user, the search log of the user to be screened is obtained, the search intention of the user to be screened is identified based on the search log, the identified intention information of the user to be screened is matched with the sensitive intention information in the preset sensitive intention information base, the target user is determined from the user to be screened according to the matching result of the intention information of the user to be screened and the sensitive intention information in the preset sensitive intention information base, the purpose of finding the target user based on the search intention of the user embodied by the search log is achieved, the calculation amount of finding of the target user is reduced, and the finding speed of the target user is favorably improved.
Fig. 3 shows a schematic view of an application scenario of the method for determining a target user according to the present application.
As shown in fig. 3, user a may issue a request 303 to find a user with illicit intent to a server 302 through an electronic device 301. The server 302 may obtain the search log in step 304, perform intent recognition on the search log in step 305 to obtain intent information of the user to be screened, which performs the search operation, and then match the intent information of the user to be screened according to a preset illegal intent information base in step 306 to determine a target user with illegal intent. Upon receiving a request 303 from the user a to find a user with illegal intent, the server 302 may feed back the determined target user to the electronic device 301 of the user a.
With continued reference to FIG. 4, shown is a flow chart of another embodiment of a method for determining a target user according to the present application.
As shown in fig. 4, a flow 400 of the method for determining a target user of the present embodiment includes the following steps:
In this embodiment, an execution subject (e.g., a server or a terminal device shown in fig. 1) of the method for determining a target user may obtain a search log of a user to be filtered. The user to be screened may be a user who searches using a search engine. Alternatively, a time period for the filtering may be specified, for example, within the last three months, and the user to be filtered may be a user who searches using the search engine within the specified time period for the filtering.
The search intention of the user to be screened, which executes the search operation, may be identified based on the search log obtained in step 201, so as to obtain intention information of the user to be screened. Specifically, the intention information of the user to be screened sending the search request in the search log can be identified based on the user query in the search log, by adopting a keyword extraction and matching method or based on a machine learning method.
After the intention information of the user to be screened is identified, the intention information can be matched with the sensitive intention information in the preset sensitive intention information base to obtain a matching result of the intention information of the user to be screened and the sensitive intention information base. When matching, a precise matching or fuzzy matching mode can be adopted, and semantic analysis and similarity calculation methods are adopted to judge whether the intention information of the user to be screened is matched with the sensitive intention information.
Step 401 and step 402 in this embodiment may also refer to the above description of step 201 and step 202, respectively, and are not described herein again.
In this embodiment, the preset sensitive intention information base includes a preset global sensitive intention information base and at least one regional sensitive intention information base corresponding to a preset geographic region. The global sensitive intention information base is a general sensitive intention information base and does not have geographical region characteristics; the locale sensitive intent information base corresponds to a particular preset geographic region and has geographic region characteristics.
For example, the global sensitive intention information base may be a nationwide sensitive intention information base, and the regional sensitive intention information base may be a sensitive intention information base in beijing, or a sensitive intention information base in shandong province. Alternatively, the global sensitive intent information store may contain all of the sensitive intent information in the locale sensitive intent information store.
In this embodiment, the intention information of the user to be screened may be respectively matched with the sensitive intention information in the global sensitive intention information base and the regional sensitive intention information base. The specific matching mode may be: semantic analysis is carried out on the intention information of the user to be screened, the sensitive intention information in the global sensitive intention information base and the sensitive intention information in the regional sensitive intention information base, and whether the intention information of the user to be screened is successfully matched with the sensitive intention information in the global sensitive intention information base and/or the regional sensitive intention information base or not is judged based on semantic similarity. Or the intention information of the user to be screened and the global sensitive intention information base and the intention information of the user to be screened and the regional sensitive intention information base can be matched in a keyword extraction and matching mode, the similarity among the intention information of the user to be screened, the sensitive intention information in the global sensitive intention information base and the sensitive intention information in the regional sensitive intention information base can be calculated, and whether the matching is carried out or not is judged according to whether the similarity reaches a preset threshold value or not.
And step 403, screening out users with intention information matched with the sensitive intention information in the global sensitive intention information base as candidate users.
In this embodiment, a user whose intention information matches the sensitive intention information in the global sensitive intention information base may be screened from the users to be screened as a candidate user. Specifically, according to the matching result in step 402, the user whose matching degree or similarity with the intention information and the sensitive intention information in the global sensitive intention information base reaches a preset threshold may be determined as a candidate user. In this way, the search scope of the target user can be firstly narrowed down from the user to be screened who sends out the search request to the candidate user whose intention information is matched with the global sensitive intention information base based on the global sensitive intention information base.
In this embodiment, the search logs of the candidate users may be selected from the search logs obtained in step 401 according to identification information such as user identification or device identification, and then the location information of the candidate users may be determined according to the search logs of the candidate users. At least one preset geographic area may be preset, and the preset geographic areas do not overlap with each other, for example, preset geographic areas such as beijing, nanjing, shanghai, guangzhou, and the like may be set. Then, a target preset geographic area where the candidate user is located may be determined according to the location information of the candidate user, that is, it is determined within which preset geographic area the location information of the candidate user falls, where the target preset geographic area where the candidate user is located is the preset geographic area where the location information of the candidate user falls.
And then, determining the target user according to the matching result of the intention information of the candidate user and the area sensitive intention information base of the target preset geographic area where the candidate user is located. Specifically, the candidate user whose intention information matches with the intention information in the area sensitive intention information base of the target preset geographic area where the candidate user is located may be used as the searched target user.
In this embodiment, the sensitive intention information bases of the preset geographic areas may be different. The regional sensitive intention information base can be constructed in advance according to regional characteristics, and then the determined target user is the user with the sensitive intention corresponding to the region where the target user is located.
In practice, different sensitive search word banks may be constructed for different regions, for example, a sensitive search word bank for the x region may include sensitive words A, B, C, D, a sensitive word bank for the y region may include sensitive words B, D, E, F, G, and so on. Therefore, the target users in different areas can be determined in a more targeted manner according to the preset sensitive word libraries in different areas.
Optionally, the preset global sensitive intention information base may be constructed by at least one regional sensitive intention information base, that is, the global sensitive intention information base may include at least one regional sensitive intention information base. Further, the global sensitive intention information base may be a set of regional sensitive intention information bases corresponding to a plurality of preset geographic regions.
Further optionally, the method flow 400 for determining the target user of the present embodiment may further include: and acquiring a regional sensitive intention information base corresponding to a preset geographic region, and constructing a global sensitive intention information base. The electronic equipment can acquire the sensitive intention information base set by the user for each preset geographic area, and then summarize the sensitive intention information bases of the areas to obtain a global sensitive intention information base.
As an example, the regional sensitive intention information bases of the preset geographic areas may be preset, and then the regional sensitive intention information bases of the preset geographic areas are summarized to generate the global sensitive intention information base.
In some embodiments, the execution subject may determine the target user as follows: and in response to determining that the intention information of the candidate user is matched with the sensitive intention information in the area sensitive intention information base corresponding to the target preset geographic area where the candidate user is located, determining that the candidate user is the target user in the target preset geographic area where the candidate user is located. That is to say, whether each candidate user is the target user of the target preset geographical area where each candidate user is located can be judged according to the area sensitive intention information of the target preset geographical area where each candidate user is located, and thus the target users of each preset geographical area can be determined, so that the target users in the sub-areas can be searched, and the searching efficiency is improved.
Further optionally, after step 400, the method flow 400 for determining the target user may further include: and adding the target users to the target user set of the corresponding target preset geographic area.
Specifically, a corresponding target user set may be created for each preset geographic area, and after the target user and the corresponding target preset geographic area are determined from the candidate users, the target user may be added to the target user set of the corresponding target preset geographic area. Therefore, the method of the embodiment can obtain the target user sets in different preset geographic areas, and can quickly provide comprehensive and accurate target user search results.
As can be seen from fig. 4, in the method for determining a target user according to this embodiment, the candidate users whose intention information matches the global sensitive intention information base are screened out, so that the search range of the target user can be quickly narrowed, and then the target users in the corresponding preset geographic area are determined from the candidate users, so that the target user can be searched differentially according to the geographic area, and the efficiency of searching by the target user is improved.
In some optional implementations of the method flow 400 for determining a target user, a target preset geographic area where a candidate user is located may be determined as follows: and determining a target preset geographical area where the corresponding candidate user is located according to the device position information of the electronic device executing the search operation in the search log. Specifically, device location information of the electronic device used when the user sends the search request may be extracted from the search log, and a target preset geographic area where a candidate user using the electronic device is located may be determined according to a preset geographic area in which the device location information falls. Here, the device location information may be generated based on a location request of the device, and may be, for example, GPS (Global Positioning System) location information, or may be determined based on an IP address of the electronic device, and may, for example, query a physical address corresponding to the IP address from the IP address of the electronic device.
In a further implementation manner, it may be determined whether the device location information of the electronic device of the candidate user includes location information generated based on the location request, and if the device location information of the electronic device of the candidate user includes location information generated based on the location request, it is determined that the target preset geographic area where the candidate user is located is a preset geographic area indicated by the location information generated based on the location request; and if the device position information of the electronic device of the candidate user does not comprise the position information generated based on the positioning request, extracting the information used for indicating the network address of the network access point connected with the electronic device in the device position information, and determining the target preset geographical area where the candidate user is located according to the geographical position information corresponding to the information used for indicating the network address of the network access point connected with the electronic device.
Specifically, it may be determined whether the search log of the candidate user includes GPS positioning information generated based on the positioning request when the search request is issued, and if so, the preset geographic area where the position indicated by the GPS positioning information is located may be determined as the target preset geographic area where the candidate user issues the search request. If the search log does not contain the GPS positioning information when the search request is sent, the corresponding geographical location information may be searched according to the network address of the wireless network access point connected when the electronic device sends the search request, for example, the GPS positioning information of other electronic devices connected to the wireless network access point may be searched according to the network address of the wireless network access point, and the GPS positioning information may be used as the geographical location information corresponding to the network address of the wireless network access point, or the geographical location information corresponding to the IP address of the wireless network access point may be used as the geographical location information of the electronic device connected to the wireless network access point. And then determining the geographical position information of the electronic equipment adopted when the candidate user sends the search request, and further determining the target preset geographical area where the candidate user is located.
