The invention provides a method for determining search requirement strength, a requirement recognition method and a requirement recognition device. The method for determining search requirement strength comprises the steps that similarity features, which belong to a preset requirement category, of queries in a search log are collected, and at least one feature is clicked; and according to each collected feature and the weight of each feature, the strength of the query in the preset requirement category is calculated. The requirement recognition method comprises the steps that online queries are obtained; offline queries in the search log, which are most similar to the online queries, are determined; and requirement categories of which the strength is greater than a preset value in the determined offline queries are used as requirements for online queries. Through the methods, the accuracy of user requirement recognition is improved.
Description
【Technical field】 [0001] The invention relates to data processing technology, in particular to a method for determining search demand strength, a demand identification method and a device thereof. 【Background technique】 [0002] With the development of search engine technology, users are not only satisfied with obtaining content matching search keywords from search engines, but hope to obtain results related to their own search purposes. In order to provide users with search results relevant to the search purpose, it is necessary to identify the user's search needs. In the existing search demand identification methods, simple rules are used to identify user needs, such as formulating a rule "all queries ending with MP3 have music needs", etc. Although this method is simple, it requires a lot of manpower Material resources are used to formulate rules, and the rules are written into the program, which greatly reduces the scalability and maintainability of the requirements ide...
