Embodiment Construction

[0060] First, an embodiment of a method for identifying search intentions in the present invention will be described. figure 1 It is a flow chart of a search intent recognition method of the present invention, the method includes the following steps:

[0061] S1: Obtain a first set of historical search sentences within a first preset time period, classify the historical search sentences in the first set of historical search sentences, and obtain special search thesaurus corresponding to each preset special category.

[0062] Since the historical search records of each user are stored in the server, the historical search records include data such as search statements input by the user, query results returned by the server, and webpages clicked and browsed by the user in the query results. The above-mentioned first preset time may specifically be the last year, one quarter, one month, etc., and the set of search statements recorded in all historical search records within the fir...

Abstract

The invention discloses a search intention identification method and device. The method comprises the steps that massive historical search statements in the historical search record are obtained and classified, a classification model is built based on the historical search statements, candidate search statements related to the historical search statements are obtained by exploring the classification model, and a special-item search word bank of a preset special-item class is formed by the historical search statements and the candidate search statements corresponding to the same preset special-item class. Compared with white lists, fuzzy search threshold values, pattern matching keywords and the like in the prior art, search statements in the special-item search word bank are more accurate and more comprehensive, the generalization is great, therefore according to the search intention identification method and device, a search intention is identified according to the special-item search word bank, the intention class of a target search statement can be identified more accurately, and the misidentification caused by inconsistency between the manually-specified rule and the actual judgment standard of a user can be avoided.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a method and device for identifying search intentions.
