Analysis and Development Strategy of Cross-Language Retrieval Function for “the Belt and Road” Multilingual Shared Database postprint

Abstract: [Purpose/significance] To realize the effective use of "the Belt and Road" multilingual shared database resources, the problem of cross-language retrieval should be solved. Based on the survey results of "the Belt and Road" database retrieval function, "the Belt and Road" multilingual shared database’s retrieval function demand is analyzed. From the perspective of researching on the cross-language retrieval platform, reference for cross-language retrieval function design and development of "the Belt and Road" multilingual shared database can be provided. [Method/process] Through literature and network survey, 11 typical cross-language retrieval platforms at home and abroad were selected. Analysis was carried out from five aspects: cross-language retrieval method, cross-language translation implementation method, retrieval function, retrieval results, interface and retrieval support language. Then concluded their implementation ways. [Result/conclusion] Based on this, strategies are proposed for the cross-language retrieval function design and development of "the Belt and Road" multilingual shared database: adopting question-document translation method based on neural machine translation, implementing multiple retrieval functions, visualization technology used to present retrieval results, providing multi-language interface and resources.
