Cross-language information retrieval apparatus and method
First Claim
1. A cross-language information retrieval apparatus which realizes document retrieval when a first language of a retrieval request is different from that of a retrieval target document, comprising:
- a document database which stores documents including each retrieval word, wherein each of the, documents is stored in accordance with a plurality of retrieval words;
an input device which inputs the retrieval request;
a machine translation device which translates the retrieval request inputted from the input device into a second language associated with the retrieval target document and generates a first of the retrieval words in the language of the retrieval target document;
a transliteration device which converts a phonogram in the retrieval request which has failed to be translated by the machine translation device into a phonogram in the second language associated with the retrieval target document and provides a result as a second of the retrieval words in the language of the retrieval target document; and
a retrieval device which retrieves a document including the first of the retrieval words and the second of the retrieval words from the document database.

Abstract
A machine translation portion machine-translates a retrieval request inputted by an input portion into the same language as that of a retrieval target document. Transliteration converts a phonogram in the retrieval request which has failed to be translated by the machine translation portion into a phonogram in the same language as that of the retrieval target document. A retrieval portion retrieves a document including the retrieval words from the document database based on the retrieval word generated by the machine translation portion and the retrieval word provided by the transliteration portion.

9. A document retrieval method in a cross-language information retrieval apparatus which realizes document retrieval when a first language of a retrieval request is different from that of a retrieval target document, comprising:
-
detecting retrieval words included in a plurality of documents and registering information indicating which document includes each retrieval word as a document database;
inputting a retrieval request;
translating the inputted retrieval request into a second language associated with a retrieval target document and generating a first of the retrieval words in the language of the retrieval target document;
converting a phonogram in the retrieval request which has failed to be translated by machine translation into a phonogram in the second language associated with the retrieval target document, and providing a result as a second of the retrieval words in the language of the retrieval target document; and
retrieving a document including the first of the retrieval words and the second of the retrieval words. - View Dependent Claims (10, 11)

12. A document retrieval program used to execute document retrieval in a cross-language information retrieval apparatus which realizes document retrieval when a first language of a retrieval request is different from that of a retrieval target document, comprising:
-
detecting retrieval words included in a plurality of documents and registering information indicating which document includes each retrieval word as a document database;
inputting a retrieval request;
translating the inputted retrieval request into a second language associated with the retrieval target document and generating a first of the retrieval words in the language of the retrieval target document;
