Claims22
A method for retrieving information from a plurality of documents in a target language using a query in a source language, including the steps of:
- converting the query into the target language using a multilingual resource,
- forming a query in the target language from the converted query and additional information on the target language, the additional information on the target language including information indicating a likelihood or probability of a converted query term in the target language being a correctly converted term,
- applying the query in the target language to an information management system which identifies a plurality of documents in the target language based on the query,
- using the additional information on the target language to re-rank the plurality of documents identified by the information management system according to a degree of relevance, and
- converting at least part or all of at least one of the plurality of documents in the target language identified by the information management system into the source language using the multilingual resource.
An apparatus for retrieving information from a plurality of documents in a target language using a query in a source language, comprising:
- a multilingual resource for converting the query into the target language,
- means for forming a query in the target language from the converted query and additional information on the target language, the additional information on the target language including information indicating a likelihood or probability of a converted query term in the target language being a correctly converted term, and
- means for applying the query in the target language to an information management system which identifies a plurality of documents in the target language based on the query,
- means for using the additional information on the target language to re-rank the plurality of documents identified by the information management system according to a degree of relevance,
- wherein the multilingual resource is arranged to convert at least part or all of at least one of the plurality of documents in the target language identified by the information management system into the source language.
A storage medium containing a program for controlling a programmed data processor of an apparatus for retrieving information from a plurality of documents in a target language using a query in a source language, the apparatus comprising:
- a multilingual resource for converting the query into the target language,
- means for forming a query in the target language from the converted query and additional information on the target language, the additional information on the target language including information indicating a likelihood or probability of a converted query term in the target language being a correctly converted term, and
- means for applying the query in the target language to an information management system which identifies a plurality of documents in the target language based on the query,
- means for using the additional information on the target language to re-rank the plurality of documents identified by the information management system according to a degree of relevance,
- wherein the multilingual resource is arranged to convert at least part or all of at least one of the plurality of documents in the target language identified by the information management system into the source language.
