Search method and search devices

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.
