中文非相关文献知识发现系统CmedLBKD构建

摘要

针对现有非相关文献知识发现系统存在的问题,开展主题概念抽取、概念修剪和排序算法等关键技术问题的研究,构建中文非相关文献知识发现系统CmedLBKD,采用Swanson提出的经典假设＂偏头痛＂和＂镁＂验证CmedLBKD系统的有效性,同时提出了系统存在的问题及将来发展的方向。%In view of the problems existing in the current disjoint literature-based knowledge discovery system,this article carries out a study of key technologies such as subject concept extraction,concept pruning and sorting algorithm,constructs the Chinese disjoint literature-based knowledge discovery system CmedLBKD,and uses the classical hypothesis proposed by Swanson about ＂migraine＂ and ＂magnesium＂ to verify the effectiveness of CmedLBKD.Meanwhile,the article points out the problems existing in the system and the direction for the future development.
