Personalized data searching method and device

Abstract

The application relates to a personalized data searching method and device. The device comprises the following steps: searching a data object according to a query word in a search request of a current user; determining a first behavior characteristic of a historic user in the search access process utilizing the query word according to a historic behavior log, and generating an intention vector of the query word; counting a second behavior characteristic of each user group to the data object according to a user attribute, and generating a preference vector of the user group; computing the similarity of the intention vector of the query word and the preference vector of each user group; using the user group corresponding to the condition that the similarity is greater than a set threshold value as a reference group for determining the intention preference of the current user; adjusting the sorting of the data objects searched by the current user through the query word through adoption of the historic behavior characteristics of the reference group. Thus the performance of a search platform is improved and promoted, the accuracy of a search result output to the user is improved, and the result, which is the most reasonable and the best for the search intention, is output for the user.

Description

technical field [0001] The present application relates to the field of data search, and more specifically relates to a personalized data search method and device. Background technique [0002] With the rapid development of Internet services, the amount of data in the network is increasing day by day. Data search engine has become an important tool to help users find their satisfactory data objects in massive data objects. Although the data search engine can filter out the search results (data objects) required by users from massive data objects, however, no matter how the data search engine is used to search for data objects, its key technology includes all Data object for sorted output processing. That is to say, after the user enters a query word, the corresponding data object is found through searching as the search result, and these search results are displayed and output in a certain sorting manner. Usually, the data search technology has nothing to do with the diffe...

Problems solved by technology

Because, according to the historical information of male users, or according to the current search keyword "dress" itself, or a combination of the two, it is difficult to give the search result ranking that best meets the current user's real needs (intent), which leads to the output of search results Sort inaccurate defects
