Example Embodiment

[0067] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following describes the present invention in detail with reference to the accompanying drawings and specific embodiments, but it is not intended to limit the present invention.

[0068] Such as figure 1 As shown, a query error correction method for Chinese search engine promiscuous language includes the following steps:

[0069] (1) Construct a heterogeneous character tree dictionary for hybrid languages, and use high-frequency or high-click query text to establish a language model.

[0070] Step (1) corresponds figure 1 In step 102 and step 106.

[0071] In step 102, the detailed process of using the thesaurus file 104 to construct a heterogeneous character tree dictionary for hybrid languages ​​is as follows: figure 2 Shown.

[0072] In the process of building the dictionary tree, the processing of Chinese characters and other characters is slightly different. It can be s...

Abstract

The invention relates to a Chinese search engine mixed speech-oriented query error corrosion method and a Chinese search engine mixed speech-oriented query error corrosion system. A mixed speech-oriented heterogeneous character tree dictionary and a language model constructed based on high-frequency or high-clicking frequency user query log are adopted for the characteristics of mixed speech query of a Chinese search engine to perform synchronous segmentation and error correction on the query of a user, and the aim of segmenting the query by switching states is fulfilled; N optimal completed states and M optimal uncompleted states after the edition of each step are recorded by adopting double queues, so that error correction speed is ensured, and in addition, an optimal segmentation mode and a corresponding substitute entry combination are obtained; and a judgment is made by utilizing the characteristics of a final error correction result candidate set, and error correction results consistent with limit conditions are output, so that accuracy is effectively improved.

Description

technical field [0001] The invention belongs to natural language processing technology, in particular to a query error correction method and system for Chinese search engine mixed language. Background technique [0002] The main way that the existing search engine interacts with the user is that the user inputs a search term, and the search engine provides a corresponding matching web page for the search term. Therefore, correctly understanding the user's query requirements from the search terms input by the user is one of the functions that the search engine needs to continuously improve. Compared with traditional text, the search terms entered by users in search engines have a higher probability of error and more types of errors, mainly due to the huge user base of search engines and the novelty and variety of online languages. According to statistics, 10%-15% of queries entered into English search engines contain spelling errors. Query error correction technology is a n...
