Matrix weighted association mode-based Indonesian and Chinese cross-language retrieval method and system

Abstract

The invention discloses a matrix weighted association mode-based Indonesian and Chinese cross-language retrieval method and system. The method comprises the steps of translating an Indonesian user query into a Chinese query by utilizing a machine translation module and submitting the Chinese query to a text retrieval module for retrieving a Chinese document; performing preprocessing by using a front initial retrieved document extraction and preprocessing module, and establishing a front initial retrieved document database; calling an Indonesian and Chinese cross-language retrieval-oriented matrix weighted association rule mining module to establish a matrix weighted association rule library; establishing an extension word base by utilizing a cross-language query extension word generation module; submitting a combined new query to the text retrieval module for retrieval again by utilizing a cross-language query extension realization module to obtain a Chinese document of a final retrieval result; and submitting the final retrieval result to the machine translation module for translation by utilizing a final result display module to obtain an Indonesian document, and returning the Indonesian document to a user. The method is applied to a cross-language text retrieval system for ASEAN countries; the cross-language retrieval performance is effectively enhanced and improved; and the application value and the popularization prospect are relatively high and good.

Description

technical field [0001] The invention belongs to the field of text information retrieval, and specifically relates to an Indonesian-Chinese cross-language retrieval method and system based on a matrix weighted association model, which is applicable to fields such as cross-language text information retrieval of Chinese documents by Indonesian language query. Background technique [0002] Cross-language information retrieval refers to the technology of retrieving information resources in other languages ​​with a query in one language. The Indonesian-Chinese cross-language information retrieval method is to query and retrieve Chinese documents in Indonesian language. The Indonesian language used to express the query is called the source language, and the Chinese language of the retrieved documents is called the target language. With the increasingly close exchanges between China and ASEAN countries, the research on cross-lingual information retrieval methods for ASEAN languages ...

AI Technical Summary

Problems solved by technology

[0003] Scholars from all over the world have conducted in-depth discussions and research on cross-lingual information retrieval methods and systems from different angles and directions, and have achieved rich results. However, the current problems in cross-lingual information retrieval research have not been completely resolved. One of the problems that have been solved and paid more attention to is the serious query topic drift problem in the process of cross-language information retrieval, which is more serious than single-language retrieval. The problem of word mismatch, these problems often lead to low performance of cross-language retrieval, Not as good as monolingual retrieval performance
