  • Patent number: 9239880
    Abstract: A method and an apparatus for identifying synonym and utilizing such synonym to conduct search is disclosed. The disclosed method includes: obtaining arbitrary two words to be identified; determining whether a shortest edit distance between the two words less than or equal to an edit distance threshold; determining whether the two words to be identified exist in a preset knowledge database, and if an answer is yes then searching a smallest granularity type with highest weight value for each word in the knowledge database; and if the two word have the same smallest granularity type with highest weight value, then determining such two words are synonyms, or non-synonym otherwise. The disclosed techniques greatly improve accuracy of synonym identification and guarantee effect of synonym identification.

  • Publication number: 20150074076
    Abstract: The present disclosure describes a search method, a search apparatus and a search system. The method includes: a data rewriting system that obtains, from a database, one or more search term candidates that are relevant to a present search term. The data rewriting system retrieves properties of the present search term and the one or more search term candidates, where the properties describe respective matching results of the present search term and the one or more search term candidates. Based on the matching results, the data rewriting system determines whether or not the present search term needs to be rewritten, and rewrites the present search term based on the matching results to provide a rewritten present search term if it is determined that the present search term needs to be rewritten. A search engine performs a search based on the rewritten present search term.
