Cross-language retrieval request conversion and cross-language information retrieval method and system

Abstract

The present invention provides a cross-language retrieval request conversion method and a device, as well as a cross-language retrieval method and a system. The cross-language retrieval request conversion method includes: a plurality of different machine translating systems are utilized to respectively carry out the translation from source language to target language according to the cross-language retrieval request, so as to obtain a plurality of target-language translations of the cross-language retrieval request; a corresponding target-language retrieval request to the cross-language retrieval request is constructed on the basis of the target-language translations of the cross-language retrieval request. The present invention constructs the target-language retrieval request by fusing the translations of the cross-language retrieval requests generated by a plurality of machine translating systems, thus increasing the retrieval performance of the language information retrieval system.

Description

technical field [0001] The present invention relates to information processing technology, in particular, to a method and device for converting cross-language retrieval requests, and a method and system for cross-language information retrieval. Background technique [0002] With the popularization of the network, the information resources on the network are increasingly abundant and the user's demand for network information resources is also gradually increasing. However, while the network information resources are becoming more and more abundant, there is a major obstacle that prevents these resources from being widely shared by users—multilingualism. The reason is that at present, one of the main ways for network users to obtain network information resources is through information retrieval systems, but traditional information retrieval systems are mainly implemented for document collections in a single language. That is to say, traditional information retrieval systems g...

Problems solved by technology

[0005] However, in previous cross-language information retrieval systems, a single machine translation system is usually directly used to generate the target language translation of the retrieval request, and then construct the retrieval formula, so the retrieval performance of such cross-language information retrieval systems depends greatly on the machine translation. The quality of the search request translations generated by the translation system

Therefore, when the translation quality of the machine translation system is poor, directly using the translation of the search request generated by the machine translation system to construct the search formula will usually make the cross-language information retrieval system obtain poor quality search results
