Abstract

The invention provides a search method and search devices. The method includes: receiving a search word input by a user; carrying out word segmentation on the search word to obtain at least one segmented word term; comparing the at least one segmented word term with disabled words in a preset disabled-word library, and determining a keyword in the search word; querying a preset company name corpusaccording to the keyword to acquire at least one Chinese character combination with the same Pinyin as the keyword, and then generating at least one word expansion sequence corresponding to the search word; calculating transition probability of the at least one word expansion sequence according to a preset transition matrix among Chinese characters; then determining a corrected search word, whichcorresponds to the search word, according to the transition probability; and carrying out retrieval on the basis of the corrected search word to acquire a search result. Therefore, the search word can be corrected in time when an error of the search word input by the user occurs, the corrected search word is adopted to carry out retrieval to obtain the search result desired by the user, thus search efficiency is improved, and search experience of the user is improved.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a search method and device. Background technique [0002] Currently, information retrieval (Information Retrieval) is the main way for users to query and obtain information. The user may input a certain search word as required, and find out the search result corresponding to the search word from the information collection by means of a search tool. For example, in the field of enterprise search, the user inputs all or part of the name of the enterprise to be searched according to needs, and obtains detailed information of the enterprise by means of an enterprise search engine.
