Problems solved by technology

[0006] However, since the calculation of the degree of association is based on the number of times the two tags appear together, for some hot tags, even if they are not related to the user tag, they will be considered as extended by the user tag. Therefore, the accuracy of user label expansion needs to be improved urgently

Embodiment Construction

[0045] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention is capable of various changes in different embodiments without departing from the scope of the present invention, and that the description and illustrations therein are illustrative in nature and not limiting. this invention.

[0046] As mentioned above, in the existing user label extension processing, the calculation of the degree of association involved refers to the multi-candidate extended label, for a candidate extended label, according to the number of times the user label and itself appear together. Degree calculation, to get the degree of association between the user label and the candidate extended label, the calculation process is as follows:

[0047] confidence(tag 1 , tag 2 )=|News(tag 1 )∩News(tag 2 )| / |News(tag 1 )|

[0048] support(tag 1 , tag 2 )=|News(ta...

Abstract

The present invention provides an extension processing method for a user tag, comprising: acquiring a user tag and a candidate extended tag; calculating the mutual information between the user tag and the candidate extended tag to obtain the relative relationship between the candidate extended tag and the user tag. The degree of association; according to the degree of association, the extension tags in the candidate extension tags are filtered to obtain the extension tags associated with the user tags, and the user tags and the associated extension tags constitute an extension relationship. In addition, an extension processing device for user tags matched with the method, a text recommendation method and device are also provided. The above-mentioned user tag expansion processing method and device can improve the accuracy of user tag expansion, and the above text recommendation method and device can implement accurate text recommendation on the basis of realizing precise user tag expansion.

Description

technical field [0001] The present invention relates to the technical field of Internet applications, in particular to a user label extension processing method, text recommendation method and device. Background technique [0002] With the realization of big data processing in Internet applications, each user has its corresponding user tags, so that various recommended applications can be realized based on user tags, and then personalized services based on user portraits can be realized. [0003] If the number of user tags of a user is sparse, the recommendation based on user tags will be limited to the user's own historical information, and the potential interests, preferences and other information will be ignored, and it will not be possible to accurately recommend the information that the user is interested in. [0004] Therefore, expansion processing of user tags is required. For example, when it is necessary to provide recommended applications with information that the ...
