汉-维跨语种农业知识库检索系统研究

Research on Retrieval System of Chinese-Uygur Cross-language Agricultural Knowledge Base

农业知识库检索系统以"服务农民、助农民增收、提高农业科技水平"为目标,充分发挥农业信息在农业农村发展中的重要功能和巨大潜力,为涉农人员提供高效、准确的农业科技知识。对于新疆少数民族聚居地区的涉农人员来说,深入研究跨语种农业知识库检索技术非常必要。介绍汉-维跨语种农业知识库检索关键技术:Lucene全文检索技术,维吾尔文处理以及汉维双语倒排索引的创建与检索。阐述了系统的设计要点:汉维双语农业知识库设计,知识录入途径以及语义检索模型设计。最后,展示了系统的实现效果。目前,该系统已投入使用,取得了良好的应用效果。

The retrieval system of agricultural knowledge base aims at serving farmers. It can increase their income and improve the level of agricultural science and technology, give full play to important function and great potential of agricultural information in agricultural and rural development, and provide efficient and accurate agricultural science and technology knowledge for agricultural personnel. It is necessary to intensively study the retrieval system of cross-lingual agricultural knowledge base for the farmers in Xinjiang minority areas. This paper introduces key technologies of Chinese-Uygur cross-lingual agricultural knowledge base retrieval: Lucene full-text retrieval technology, Uygur language processing, creation and retrieval of Chinese-Uygur bilingual inverted index. Main points of system design are expounded as follows: design of Chinese-Uygur bilingual agricultural knowledge base, ways of knowledge input and design of semantic retrieval model. Finally, implementation effect of the system is shown. At present, the system has been put into use and achieved good application results.
