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 invention provides a user tag extension treatment method. The method includes the steps of obtaining a user tag and candidate expanded tags, conducting mutual information calculation between the user tag and the candidate expanded tags to obtain the correlation of the candidate expanded tags relative to the user tag, screening out extension tags in the candidate expanded tags according to the correlation to obtain the extension tags correlated to the user tag, wherein an extension relation between the user tag and the correlated extension legs is formed. In addition, the invention further provides a user tag extension treatment device matched with the method and a text recommendation method and device. By means of the user tag extension treatment method and device, the user tag extension precision can be improved; by means of the text recommendation method and device, the text precise recommendation can be realized on the basis of user tag precise extension.

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 ...
