A method and device for determining target object information corresponding to a user

Abstract

The invention aims to provide a method and equipment for determining target object information corresponding to a user in a resource information database. Processing equipment performs match inquiring in the resource information database according to an index word of the user to obtain candidate target object information corresponding to the index word, retrieval application information corresponding to the candidate target object information is determined according to corresponding retrieval log information of the user under the index word, and the target object information corresponding to the user in the resource information database is determined according to one or more pieces of candidate target object information and the retrieval application information. Compared with the prior art, the method and the equipment have the advantages that the target object information is obtained in a specific resource range, the accuracy and completeness of the obtained target object information are improved, the target object information obtaining efficiency is improved, further services such as personalized recommendation are accurately performed for the user, and the user experience is improved.

Description

technical field [0001] The present invention relates to the Internet field, in particular to a technology for determining target object information corresponding to a user in a resource information database. Background technique [0002] Currently, the determination of the user's target object information (such as the user's point of interest) is mainly performed through text analysis or proper name recognition. The text analysis method refers to collecting the search word information of all users, and the title and text information in the text of the webpage viewed by the user, using a latent language model or a text clustering method to establish N target object information, and then separately Calculate each user's degree of interest in each target object information or directly use the N target object information as the target object information owned by each user; the proper name recognition method refers to first establishing a proper name dictionary (such as the name...

Problems solved by technology

[0003] However, the user's target object information (such as the user's point of interest) reflected by the text analysis method is not clear and specific enough, and the abstract concept of clustering can only be used to describe which words the user is interested in from the text level. Unable to accurately describe the user's interest in a certain type of entity (movies, TV series, animation, variety shows, etc.)

The proper name recognition method can describe the user's target object information (such as the user's point of interest) to the level of entity proper names, but due to the ambiguity of a word, the accuracy of the method of matching proper names only from search terms Not high, it is easy to cause errors in the identification of user points of interest; in addition, due to the existence of the same name and aliases, many user points of interest may also be missed
