摘要： A search method uses pseudo-anchor text associated with search objects to improve search performance. The pseudo-anchor text may be extracted in combination with an identifier of the search objects (such as a pseudo-URL) from a digital corpus such as a collection of documents. Pseudo-anchor texts for each object are preferably extracted from candidate anchor blocks using a machine learning based approach. The pseudo-anchor texts are made available for searching and used to help rank the objects in a search result to improve search performance. The method may be used in vertical search of objects such as published articles, products and images that lack explicit URLs and anchor text information.

摘要： A search system includes: a data rewriting system that obtains, from a database, one or more search term candidates that are relevant to a present search query. The data rewriting system retrieves properties of the present search query and the one or more search term candidates, where the properties describe respective matching results of the present search query and the one or more search term candidates. Based at least in part on the matching results, the data rewriting system determines whether or not the present search query needs to be rewritten, and rewrites the present search query based at least in part on the matching results to provide a rewritten present search query if it is determined that the present search query needs to be rewritten. A search engine performs a search based at least in part on the rewritten present search query.
