基于《中图法》的网络农业信息分类编码研究

Study on Classification and Coding for Web Agricultural Information Based on China Library Classification

针对目前农业网站信息管理与共享的需求，提出了一套网络农业信息分类编码体系。通过分析国内代表性农业网站信息分类的特点及《中图法》网络应用的优缺点，以“华中农业信息网”多年采编的信息作为实验材料，在考虑网络农业信息特点的基础上对《中图法》的农业及相关类目进行了网络适应性改造，进而提出了网络农业信息分类编码方法。该体系克服了全新分类体系网络应用性差、信息覆盖面不全的问题。研究结果对网络农业信息有效管理，提高信息利用率，促进信息资源共享具有积极作用。

A system of classification and coding for web agriculture information is developed to meet the need of information management and sharing in agricultural website. By analyzing the characteristics of information classification in domestic representative agricultural website and the advantages and disadvantages of CLC, taking the information in www. ccain, net as experimental material, fully considering the features of agricultural web information , the paper has the agriculture and the related category in CLC altered to adapt to network environment, and proposes the web agricultural information classification and coding scheme. It overcomes the problems that a new classification system doesn＇t suit the network application vary well and can＇t cover information completely. The research results have a positive effect to effective web agriculture information management, raise the information use factor, promote the sharing of information resources.
