Embodiment 1

[0080] See figure 1 , which shows a flow chart of the search word recognition method provided by the present application, which may include the following steps:

[0081] Step S11: Calculate the search click-through rate of the search term to be recognized.

[0082] In this embodiment, the search click-through rate of the search term to be identified refers to the ratio of the number of times the search result is clicked on the search term to be identified to the number of searches. The number of clicks on the search results refers to the number of times the user clicks on the search results returned by the search engine for the search words to be identified; the number of searches refers to the number of times the user searches for the search words to be identified.

[0083] Because the wrong search term cannot correctly describe the user's search intention, it often leads to the user's low satisfaction with the search result, and the user's search click-through rate is low. ...

Embodiment 2

[0145] Corresponding to the above method embodiments, this embodiment provides a search word recognition device, please refer to Image 6 , The device for identifying search words includes: a first calculation unit 61 , a word segmentation unit 62 , a second calculation unit 63 , a third calculation unit 64 , a fourth calculation unit 65 and a determination unit 66 .

[0146] The first calculating unit 61 is used to calculate the search click-through rate of the search term to be identified.

[0147] The word segmentation unit 62 is configured to perform word segmentation processing on the search word to be recognized to obtain a plurality of word features.

[0148] The second calculation unit 63 is configured to calculate the occurrence probability of the search word to be recognized by using the statistical language model and the features of each word.

[0149] The third calculation unit 64 is used to calculate the number of full matching results and the number of related r...

Abstract

The invention provides a search word recognition method and device. The search word recognition method comprises the following steps: calculating the search click rate of search words to be recognized; performing word segmentation processing on the search words to be recognized to obtain a plurality of word features; calculating the appearance probability of the search words to be recognized by utilizing a statistical language model and each word feature; calculating the number of full matching results and the number of related results of the search words to be recognized; calculating the ratio of the number of full matching results to the number of related results to obtain a full matching ratio; determining the search words to be recognized as error search words or normal search words by utilizing the search click rate, each word feature, the appearance probability of the search words to be recognized, the number of the full matching results and the full matching ratio. In the invention, in such a manner, an intelligent error correction technology can recognize the more error search words, so that the more error search words are corrected; a search engine returns more accurate search results to a user, so that the experience of the user is improved.

Description

technical field [0001] The present application relates to the field of computers, and in particular to a search word recognition method and device. Background technique [0002] The search words received by the search engine often contain wrong search words (such as search words caused by wrong selection of homophones, search words caused by spelling mistakes, and search words caused by typographic input errors), resulting in search results that cannot satisfy users. demand. In order to solve the above problems, intelligent error correction technology is often used to correct wrong search terms and return more accurate search results to users. [0003] Among them, the intelligent error correction technology is mainly divided into two steps: identifying wrong search words and correcting wrong search words. However, the ability of intelligent error correction technology to identify wrong search words is limited, resulting in many wrong search words not being recognized, resu...
