HNC农村智能信息检索系统

设计并实现了一个基于概念层次网络（HNC）的农村智能信息检索系统。该系统采用语境框架对文本进行形式化，即把文本内容抽象成领域(静态范畴)、情景(动态描述)、背景(褒贬、参照等)3个侧面。在语境框架的基础上，设计实现了信息检索算法。算法以领域为中心，以情景框架为依托，以背景框架为限定。系统运行1年来已经取得了非常好的效果，充分验证了技术的可行性。

Intelligent Agriculture Information Retrieval System Based HNC

An intelligent agriculture information retrieval system based on hierarchical network of concepts (HNC) is designed and developed. In the system, a model of semantic-based text formalization, the context framework model (CFM) is presented, which is three-coordinate and describes the text as domain, situation and background. Based on the context framework, an information retrieval algorithm is developed. The algorithm has a kernel of domain knowledge, a base of situation framework and a limitation of background. The good effect during the run of the system for one year proved the feasibility of the technology.
