Embodiment Construction

[0040] In order to make the above objectives, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] The embodiment of the present invention provides a query correction method. For the search query input by the user, there may be multiple errors or it is not conducive to the search engine to correctly analyze the user's search intent, resulting in a search failure. A variety of correction analysis, using the language model established in advance according to the retrieval resources as a measurement standard, and then searching for several query correction suggestions that best match the language model through an effective search algorithm, which can be used as explicit prompts or implicit The query is passed to the retrieval part to help users retrieve the expected results as much as possible, avoiding users to mo...

Abstract

The invention discloses a kind of method and system for searching and modifying, solving the problem that the current search engine can analyze many wrong searching information which users input correctly, thereby, resulting in searches failing. The method above includes: setting in advance the language model with the search resource; using the relevant correcting operation, correcting every search word input initially, getting many expressions of the relevant search word which including the expression of the initial input; according many expressions of every search word, getting the different assembled-form word serial; using the language model referred above to compute the appearance probability of the word serial, and making the word serial with high appearance probability as the search suggested result. The invention can deal unitarily with many inputting mistakes or incomplete inputting appearing during searching such as spelling mistake, morphology imperfection and so on to reach the aim to correct the search automatically, to help users to use the search engine efficiently.

Description

Technical field [0001] The invention relates to search engine technology, in particular to a query correction method and system in a search engine. Background technique [0002] Query refers to the user's input when using a search engine, and specifically refers to text input here. Query is the expression of user's information needs. Only when search engines correctly "understand" the user's query, can it provide users with accurate search results and provide users with high-quality services. However, when current search engines analyze users’ queries, their accuracy will be affected and restricted by several factors, such as misspellings, incorrect word forms, incomplete input words, Chinese homophones, etc., making the search engine unable to correct " Understand the user's intention, the returned search results cannot meet the user's needs. [0003] Existing search engines, such as Google, Youdao, Baidu, etc., attach great importance to query processing functions, and provide ...
