Triangulation without translation.
Proceedings of the 27th annual international ACM SIGIR conference on Research and development in information retrieval(2004)
摘要
Transitive retrieval and triangulation have been proposed as ways to improve cross-language retrieval quality when translation resources have poor lexical coverage. We demonstrate that cross-language retrieval is viable for European languages with no translation resources at all; that transitive retrieval without translation does not suffer the drop-off in retrieval quality sometimes reported for transitive retrieval with translation; and that triangulation that combines multiple transitive runs with no translation can boost performance over direct translation-free retrieval.
