Indonesian-Chinese cross-language retrieval method and system integrating association model and user feedback

Abstract

The invention discloses an Indonesian-Chinese cross-linguistic retrieval method and system capable of integrating an association pattern with user feedback. The method comprises the following steps: utilizing a machine translation module to translate an Indonesian user query into a Chinese query, and submitting the Chinese query to a search engine module to carry out retrieval to obtain an initial retrieval result document set; utilizing the relevant feedback information extraction module of a user clicking behavior to obtain a user feedback initial retrieval related document set; carrying out preprocessing through a document preprocessing module to obtain an initial retrieval related document database; calling an all-weighted association rule mining module to construct an all-weighted association rule base; utilizing a cross-linguistic query expansion word generation module to establish an expansion word bank; utilizing a cross-linguistic query expansion implementation module to submit a new combined query to the search engine module to obtain a final retrieval result Chinese document; and utilizing a final result display module to submit a final retrieval result to the machine translation module, translating the final retrieval result into an Indonesian document, and returning the Indonesian document to the user. By use of the method and the system, cross-linguistic retrieval performance can be effectively enhanced and improved, and the method and the system have a good practical application value and popularization prospect.

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 that integrates association patterns and user feedback, and is applicable to fields such as cross-language text information retrieval that uses Indonesian language to query and retrieve Chinese documents. 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 ...

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
