When the servers 101 and 102 are hardware, they may be implemented as a distributed server cluster composed of multiple servers, or may be implemented as a single server. When the servers 101, 102 are software, they may be implemented as multiple pieces of software or software modules (e.g., to provide distributed services), or as a single piece of software or software module. And is not particularly limited herein.
It should be noted that the method for generating the tag provided by the embodiment of the present application is generally performed by the server 102, and accordingly, the apparatus for generating the tag is generally disposed in the server 102.
It should be understood that the number of servers and networks in fig. 1 is merely illustrative. There may be any number of servers and networks, as desired for implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of a method for generating a tag in accordance with the present application is shown. The method for generating the label comprises the following steps:
step 201, obtaining an application name list of applications operated by a user in a historical time period.
In this embodiment, an execution subject (for example, the server 102 shown in fig. 1) of the method for generating a tag may obtain, through a wired connection manner or a wireless connection manner, an application name list of applications that have been operated by a user in a historical time period (for example, in the previous three months) from a background server (for example, the server 101 shown in fig. 1) of an application market or a cell phone assistant. The applications operated by the user may include, but are not limited to, applications downloaded by the user, applications installed by the user, applications used by the user, applications updated by the user, applications uninstalled by the user, and the like. The application name may include, but is not limited to, the name of the application, the name of the installation package of the application, and so forth. Generally, when a user operates an application, information of the application operated by the user may be fed back to a background server of the application marketplace or the mobile phone assistant, so that the background server of the application marketplace or the mobile phone assistant records an application name of the application in an application name list of the application operated by the user. Therefore, the execution subject may obtain the application name list of the applications operated by the user in the historical time period from the application market or the background server of the mobile phone assistant.
Step 202, obtaining relevant information of the application in the application name list.
In this embodiment, the execution main body may obtain the relevant information of the application in the application name list from a background server of an application market or a mobile phone assistant, a background server of an encyclopedia application, or a background server of a search application in a wired connection manner or a wireless connection manner. The related information of the application may include, but is not limited to, introduction information of the application, evaluation information of the application by the user, and the like. Generally, the background server of the application market or the mobile phone assistant may further store introduction information of the application and evaluation information of the user on the application, so that the execution subject may obtain the application name list from the background server of the application market or the mobile phone assistant, and also obtain the introduction information of the application and the evaluation information of the user on the application in the application name list. The execution main body may also search, based on the application name in the application name list, a background server of the encyclopedic application or a background server of the search application, so as to obtain the relevant information of the application in the application name list.
And step 203, determining the crowd category to which the user belongs based on the application name list and the related information.
In this embodiment, the execution subject may analyze the application name list and the related information to determine the crowd category to which the user belongs. For example, if the application is determined to be a cloud service application of a certain brand of automobile according to the application name and related information of the application, the user belongs to the owner of the brand of automobile. For another example, if the application is determined to be a driver-side application based on the application name and related information of the application, the user belongs to a driver.
And step 204, generating corresponding crowd category labels based on the crowd categories to which the users belong.
In this embodiment, the execution subject may generate a corresponding crowd category label based on the crowd category to which the user belongs.
In some optional implementations of the embodiment, the execution subject may generate the user portrait of the user based on the crowd category tag of the user, so as to improve accuracy of depicting the user portrait on the attribute of the user. The execution subject may then determine the interest points of the user based on the representation of the user, thereby improving the accuracy of the determined interest points. Finally, the execution main body can also push information for the user according to the interest point of the user, so that the accuracy of information pushing is improved.
According to the method for generating the label, firstly, an application name list of an application operated by a user in a historical time period is obtained; then acquiring relevant information of the application in the application name list; and finally, determining the crowd category to which the user belongs based on the application name list and the related information, and generating a corresponding crowd category label based on the crowd category to which the user belongs. The crowd category to which the user belongs is determined based on the application operated by the user, so that the accuracy of the determined crowd category is improved, and the depicting accuracy and the refining degree of the user attribute are improved.
With further reference to fig. 3, a flow 300 of yet another embodiment of a method for generating a tag in accordance with the present application is shown. The method for generating the label comprises the following steps:
step 301, obtaining an application name list of applications operated by a user in a historical time period.
Step 302, obtaining relevant information of the application in the application name list.
In the present embodiment, the specific operations of step 301-.
Step 303, extracting keywords in the application name list and the related information by using a natural language processing technology.
In the present embodiment, an execution subject (e.g., the server 102 shown in fig. 1) of the method for generating a tag may extract a keyword from the application name list and the related information. In general, the execution agent may extract keywords in the application name list and the related information using NLP (natural language Processing) technology. NLP, among other things, is a way for computers to analyze, understand and capture meaning from human language in a clever and useful way. By utilizing NLP, developers can organize and build knowledge to perform tasks such as automatic summarization, translation, named entity recognition, relationship extraction, emotion analysis, speech recognition, and topic segmentation.
And 304, matching the keywords in the application name list and the related information in a preset first crowd category set to obtain a successfully matched first crowd category as the crowd category to which the user belongs.
In this embodiment, the execution subject may preset the first crowd category set. For example, the executing entity may generate the first set of crowd categories based on various automobile brands. At this time, the first group category set includes categories of owners of vehicles of various brands. Then, the execution subject may match the keywords in the application name list and the related information with each first group category set in the first group category set one by one, and if the keywords in the application name list and the related information are the same as the automobile brand corresponding to one first group category, the matching is successful, and the first group category is the successfully matched first group category, which may be the group category to which the user belongs.
Step 305, generating a corresponding crowd category label based on the crowd category to which the user belongs.
In this embodiment, the specific operation of step 305 is substantially the same as the operation of step 204 in the embodiment shown in fig. 2, and is not repeated herein.
As can be seen from fig. 3, compared with the embodiment corresponding to fig. 2, the flow 300 of the method for generating a tag in this embodiment highlights the step of matching the keywords in the application name list and the related information in the first crowd category set to obtain the crowd category to which the user belongs. Therefore, the crowd category to which the user belongs is obtained based on the keyword matching, and the accuracy of the determined crowd category is further improved.
With further reference to FIG. 4, a flow 400 of yet another embodiment of a method for generating labels in accordance with the present application is illustrated. The method for generating the label comprises the following steps:
step 401, an application name list of applications operated by a user in a historical time period is obtained.
Step 402, obtaining relevant information of the application in the application name list.
In the present embodiment, the specific operations of steps 401-402 are substantially the same as the operations of steps 201-202 in the embodiment shown in fig. 2, and are not repeated herein.
And 403, identifying the prefixes and/or suffixes of the application names in the application name list by using the Chinese language model to obtain an identification result.
In the present embodiment, an execution subject (e.g., the server 102 shown in fig. 1) of the method for generating a tag may identify a prefix and/or a suffix of an application name in the application name list to obtain an identification result. Generally, the execution agent may identify prefixes and/or suffixes of application names in the application name list using a chinese language model to obtain an identification result. The N-Gram is a Language Model commonly used in large vocabulary continuous speech recognition, and is also called a Chinese Language Model (CLM). The Chinese language model can realize automatic conversion to Chinese characters by using collocation information between adjacent words in the context.
In some optional implementation manners of this embodiment, the prefix and/or the suffix of the application name of the part of applications may reflect the occupation of the user, at this time, the prefix and/or the suffix of the application name of the part of applications are identified, and the obtained identification result may be the occupation of the user. For example, for an application with an application name of "х х driver end of the driver generation", the corresponding recognition result may be the driver generation. For another example, for an application with an application name of "х х doctor version", the corresponding recognition result may be a doctor.
And step 404, matching the recognition result in a preset second crowd category set to obtain a second crowd category successfully matched with the recognition result as the crowd category to which the user belongs.
In this embodiment, the execution subject may preset the second crowd category set. For example, the executive may generate the second set of crowd categories based on various types of professions. At this point, various types of professions are included in the second set of demographic categories. Wherein the source of the occupation type may include, but is not limited to, being captured from a professional-type technical examination site. Then, the executing body may match the recognition result with each of the second crowd category sets one by one, and if the recognition result is the same as the occupation type corresponding to one second crowd category, the matching is successful, and the second crowd category is the successfully matched second crowd category, which may be the crowd category to which the user belongs.
In some optional implementation manners of this embodiment, the execution main body may further perform statement structure analysis on the statements in the related information to determine statements that conform to a preset statement structure; and matching the sentences conforming to the preset sentence structures in a second crowd category set to obtain a second crowd category successfully matched with the sentences conforming to the preset sentence structures and serve as the crowd category to which the user belongs. As an example, the executing entity may determine a sentence with a sentence structure of "special х х" from the related information, and then match the sentence with the sentence structure of "special х х" with each second crowd category in the second crowd category set one by one, if there is a keyword identical to one second crowd category in the sentence with the sentence structure of "special х х", the matching is successful, and the second crowd category is the successfully matched second crowd category, that is, the crowd category to which the user belongs. For example, a statement "exclusively х х" may be "intelligent teaching software developed exclusively for teachers," and the keyword "teacher" in the statement may be successfully matched with a second crowd category corresponding to "teacher" in the second crowd category set.
Step 405, generating a corresponding crowd category label based on the crowd category to which the user belongs.
In this embodiment, the specific operation of step 405 is substantially the same as the operation of step 204 in the embodiment shown in fig. 2, and is not described herein again.
As can be seen from fig. 4, compared with the embodiment corresponding to fig. 2, the flow 400 of the method for generating a label in this embodiment highlights a step of matching the recognition results corresponding to the prefixes and/or suffixes of the application names in the application name list in the second crowd category set to obtain the crowd category to which the user belongs. Therefore, the crowd category to which the user belongs is obtained based on the matching of the identification results corresponding to the prefix and/or suffix of the application name, and the accuracy of the determined crowd category is further improved.
With further reference to fig. 5, a flow 500 of another embodiment of a method for generating a tag in accordance with the present application is shown. The method for generating the label comprises the following steps:
step 501, obtaining an application name list of applications operated by a user in a historical time period.
Step 502, obtaining relevant information of the application in the application name list.
In the present embodiment, the specific operations of steps 501-502 are substantially the same as the operations of steps 201-202 in the embodiment shown in fig. 2, and are not repeated herein.
Step 503, extracting keywords in the related information by using natural language processing technology.
In the present embodiment, an execution subject (e.g., the server 102 shown in fig. 1) of the method for generating a tag may extract a keyword from the related information. In general, the execution subject may extract keywords in the related information using NLP technology.
Step 504, classifying the applications in the name list by using the application names in the application name list and the keywords in the related information as classification features, and determining the crowd category to which the user belongs based on the classification result.
In this embodiment, the execution subject may first classify the applications in the name list by using the application names in the application name list and the keywords in the related information as classification features; and then determining the crowd category to which the user belongs based on the classification result. Generally, the execution subjects may be classified using a clustering method. Clustering is the process of dividing a collection of physical or abstract objects into classes composed of similar objects. The cluster generated by clustering is a collection of a set of data objects that are similar to objects in the same cluster and distinct from objects in other clusters. Subsequently, the execution subject may extract key information of applications in the same cluster, and determine the crowd category based on the key information.
And 505, generating a corresponding crowd category label based on the crowd category to which the user belongs.
In this embodiment, the specific operation of step 505 is substantially the same as the operation of step 204 in the embodiment shown in fig. 2, and is not repeated herein.
