Abstract

The present invention provides an evaluation method for judging the validity of search intent recognition, comprising the following steps: S1, obtaining the total number of word segmentations and information of each word segmentation in the search intent recognition process to be evaluated; S2, calculating separately according to the information The sum of the word frequencies corresponding to each word segment and the inverted document frequency; S3, using the sum of the word frequencies corresponding to each word segment obtained in step S2 and the inverted document frequency to calculate the search intent identification process to be evaluated. Effectiveness score, and then determine whether the search intent recognition process is effective. The present invention also relates to related computer-readable storage media and electronic devices.

Description

technical field [0001] The invention relates to the field of big data search, in particular to an evaluation method for judging the effectiveness of search intent recognition, related storage media and electronic equipment. Background technique [0002] On the live broadcast platform, users' real intentions can be guessed based on their search queries, and more accurate search results can be returned through their real intentions. However, it needs to be measured to what extent the result can reflect the real intention of the user. If the correlation is poor, the actual utility of the identified weak intention will be very low. Therefore, the problem we need to solve is how to measure the relevance of intent matching, so as to judge the effectiveness of intent recognition. [0003] Unlike the scenario where the results are returned directly based on the text matching of the search terms, there may be no textual correlation between the search results returned after using the...
