【摘要】 信息化是当今世界经济和社会发展的一大趋势,是促进各项产业优化升级、实现国民经济现代化的关键环节,也是衡量国家综合实力的重要标志。农业作为国民经济的基础产业和重要组成部门,必须紧跟信息化的潮流,抓住信息化的机遇,加快信息化的进程,这样才能适应经济和社会发展的要求。随着信息化在农业领域的深入,各种农业专家系统、农业网站迅猛发展。但各类涉农信息应用质量参差不齐,服务目标、服务宗旨也各有不同,用户在利用信息系统查询自己所需信息资源的时候,没有一个客观的评价标准,对信息资源的利用往往会比较盲然无目标,因此对农业信息系统的内容及访问农业信息系统的用户行为进行研究是很有必要的。信息构建是网站的蓝图,是人们在互联网信息环境中成功地管理和查找信息的基础。尽管人们在与网站发生交互的过程中己经接触到了信息构建的主要元素——组织系统、导航系统、标识系统和搜索系统,并且利用它们管理、查找信息,但是真正意识到这些元素存在的人却不多,更不用说了解信息构建对于网站效率的重要性了。本文旨在介绍网站信息构建和Web日志挖掘知识的基础上,重点对运行6年的东北农业大学农业专家在线网站进行Web日志挖掘研究,对运行以来积累的海量Web日志数据进行有效的预处理,并采用SAS数据挖掘模块对日志数据进行关联规则挖掘、链接分析,并利用挖掘的结果对网站信息构建合理性进行评估及改造,逐渐在个性化服务、改进系统性能、站点内容修改、商业智能等方面提供科学的理论基础,使之成为农业网站的佼佼者。本文构建了信息构建和Web日志挖掘两项技术在农业网站建设中的应用模式,针对农业网站信息用户需求的特点,在农业网站建设和服务过程中,通过引入信息构建和Web日志挖掘,不仅能为用户提供满意的服务,而且可以对其他农业信息系统的构建及运行等方面提供一定的借鉴作用,并对我国农业信息化进程起到很大作用。更多还原

【Abstract】 Information is the world’s economic and social development of a major trend is to promote the optimization and upgrading of industries, modernization of the national economy the key measure of comprehensive national strength is also an important symbol. Agriculture as the foundation of the national economy and an important industrial sector, we must closely follow the trend of information technology, information technology to seize the opportunity and speed up the process of information, so as to adapt to economic and social development. Along with high speed development of Internet and informational advancement of all kinds of industry, agricultural websites are accelerated to develop very quickly. But the quality of these agricultural websites rather spotty. They have their own service aim or service purpose. Then, when user seeks wanted information by using agricultural websites, he will feel absentminded for how to use these information without a objective evaluation standard. In the last few years, the government pays much attention to agriculture, country and peasant, so it’s necessary to research agricultural website content and web usage.Information architecture is the blueprint for designing large-scale websites, and the basis on which we can manage and find information successfully in the information environment of World Wide Web. Although most people have touched orgnization systems, navigation systems, labeling systems and searching systems, the main elements of information architecture when they are interacting with the websites, few of them really realize the existence of these elements, let alone understanding the importance of information architecture to website effectiveness.This paper aims to introduce the web site information Web Log Mining Construction and the basic knowledge, on the basis of six years of operation in Northeast Agricultural University agricultural expert online system for Web log mining research, has been running the massive accumulation of data for Web log effective pretreatment, and the adoption of SAS Data Mining module of association and link analysis, and use the results of the excavation site of the Information Architecture reasonable assessment and transformation, to become excelent agricultural site.Finally, the paper constructs the application model of Information architecture and weblog mining in the agricultural website. In the website construction and service process, this kind of technology can help to grasp the characteristics and requirements of individual and provide the process of agricultural information.更多还原
