Method for for multilingual information retrieval

摘要

A computer-implemented method for retrieving multi-lingual information in a server interacting with a collection of documents and a set of language-specific indices is disclosed. In at least one data-storage device a set of one or more language-specific indices are defined for a collection of documents with each index including stemmed and non-stemmed versions of terms contained in the documents; A query is received from a user, with the query associated with a set of one or more target languages. Using at least one processor the query is parsed into one or more terms with each term associated with a corresponding language identifier and a stemmed version of the term. Using at least one processor the non-stemmed and stemmed versions of each term are translated into each of the target languages to define respective sets of one or more equivalent query terms. Using at least one processor a set of documents are identified from the collection of documents for each of the target languages, with each set identified based on the equivalent query term for the corresponding target language.
