Indonesian-English cross-language post-translation part extension method based on item weight sorting mining

Abstract

The invention discloses an Indonesian-based on item weight sorting mining. The invention discloses an English cross-language translated postpartum extension method. The method comprises the followingsteps: firstly, retrieving an English document for Indonesian language query in a cross-language manner; constructing an initially-detected user-related feedback English document set; then, in combination with the translated English original query lexical item, fusing the weight and frequency of the item set with the total weight of the feature words of the English document set fed back by the initial detection user and the total number of the documents; adopting A support degree-confidence coefficient-correlation coefficient evaluation framework to mine a feature word weighted association rule, wherein a feature word weighted association rule front part is an original query word item set, a feature word weighted association rule rear part is composed of non-query word items, the feature word weighted association rule rear part is extracted to serve as a post-translation expansion word, and Indonesia-correlation is achieved. And expanding the translated part of the English cross-language query. According to the method, the item set is pruned through item weight sorting, the mining efficiency is improved, the extension words related to the original query can be mined, and Indonesian-is achieved. British cross-language translated postpartum extension to improve and improve Indonesian- And the English cross-language information retrieval performance is realized.

Description

technical field [0001] The invention belongs to the field of information retrieval, in particular to an Indonesian-English cross-language post-translation extension method based on item weight sorting and mining. Background technique [0002] Cross-language query expansion refers to the process of using a certain strategy to find the expansion words related to the original query in the process of cross-language information retrieval, and then combining the expansion words and the original query to obtain a new query and re-retrieval. Cross-language query expansion is one of the key technologies to enhance and improve the performance of cross-language information retrieval, and it can solve the long-term problems in cross-language information retrieval, such as severe drift of query topics and word mismatch. According to different stages of cross-language information retrieval, cross-language query expansion can be divided into three types: query pre-translation expansion, qu...
