基于本体论的土壤知识体系智能检索系统的设计与Web实现

Design and Web implementation of soil knowledge intelligent retrieval system based on ontology

从大量的网络信息资源中快速、准确地找到所需的信息已成为阻碍人们开发利用网络信息资源的严重屏障 ,也成为网络信息资源共享研究的一个热点。针对农业知识本体论 (Ontology)基础研究特点 ,结合土壤与农业化学专业知识 ,本文以土壤分类体系为例 ,采用纯XML(eXtensibleMarkupLanguage)数据库Tamino作为信息导航库 ,根据用户输入的查询条件 ,以直观的树型结构来显示相关分类信息 ,通过点击方式理解用户的需求 ,实现Web智能检索。

With the development and popularization of Internet, more and more people depend on network to exchange messages and obtain information. But it is a critical handicap to exploit networks information resources and quickly and exactly obtain the required information from the huge bank. Therefore how to share the network information resource becomes a research hot-spot.Based on ontology theory of agricultures characters and combined with the knowledge of soil and agricultural chemistry, a web system was made for the soil knowledge system with native XML(extensible Markup Language)Database-Tamino as information navigation. This system could display relevant information in a tree structure and understand users demands.
