【摘要】：随着网络和信息技术的广泛应用与快速发展,各种基于信息处理的门户网站被应用在企业、政府、科研机构等不同的领域,并且都取得了良好的应用效果,推动了各个领域信息化水平的发展。近些年在农业发展领域,也涌现了大量针对不同规模、不同应用的信息服务系统,但是由于各个系统之间采用的技术存在差异性,导致系统间相互独立、数据不能共享以及系统功能重复开发等问题,严重阻碍了农村信息化的发展。因此,有效解决“信息孤岛”问题,为用户提供更优的资源访问模式以及更加有条理的个性化信息服务,是目前农村信息化建设最为紧迫的任务。本研究以“内容域界定-内容管理-系统集成”为主线,采用Portal、SOA等技术设计门户体系结构、内容管理、系统集成等方案开发农村信息服务门户系统,将信息用户所需要的数据资源在门户平台中,有效地解决了上述问题。本文主要研究内容包括:(1)基于Portal技术,提出构建农村信息服务门户的体系结构,重点研究了实现信息门户核心技术及其关键组件,从原理、体系结构等方面进行阐述,并提出内容聚集展现设计和系统集成等方案。(2)通过调研分析服务对象的分类、用户需求分类,确定内容服务提供者、内容栏目以及角色设置;结合用户需求,对信息服务内容分类,从六大模块进行信息聚集设计,完成了门户信息分类与资源目录设计。(3)在内容管理过程中,通过采用人工采编、会员发布及网络抓取三种方式收集农业信息数据,经处理之后进行发布。在数据模型设计中,针对普通用户、会员用户、超级管理员、栏目管理员四种角色进行了数据流分析和数据字典说明。(4)通过深入研究Portal门户框架,最后选择开源门户平台Jetspeed2进行二次开发,实现内容管理、系统集成等功能,构建了农村信息服务综合门户原型,并进行了验证。本文以农村信息服务门户的集成与实现为目标,为农村农业信息用户提供了高效、方便快捷的信息服务,对农村农业信息化建设具有普遍意义以及较高的实用价值。
[Abstract]:With the wide application of network and information technology and the rapid development of various information processing based portals are used in business, government, research institutions and other different fields, and have achieved good application effect, promote the development of informatization level in various fields. In recent years in the field of agricultural development, but also the emergence of a large number of the information service system of different scale, different applications, but due to the technical differences between the various systems, causing the system independent, the data can not be shared and system functions of duplication of development and other issues, has seriously hindered the development of rural informatization. Therefore, effectively solve the problem of "information island", to provide users with better resources access mode and more personalized information service organization, is currently the construction of rural informatization is the most urgent task. This study takes content in domain. Content management system integration "as the main line, using Portal, SOA and other technical design portal architecture, content management, system integration and development scheme of rural information service portal system, information users need data resources in the portal platform, effectively solve the above problems. The main contents of this paper include: (1) based on the Portal technology, put forward a system structure of rural information service portal, focus on the implementation of information portal core technology and key components, from the principle, system structure and so on, and put forward the content aggregation show design and system integration scheme. (2) through the investigation and analysis of the classification of the service object, the user needs to determine the classification. Content providers, content section and character set; combined with the demand of the user, classification of information services, information gathered from the design of six modules, complete information portal With the resource directory design. (3) in the content management process, through the use of artificial editing, data collection of agricultural information publishing and web crawl membership in three ways, after treatment were released. In data modeling, for ordinary users, members of the user, the super administrator, the administrator role of four columns of data flow analysis and data dictionary. (4) through an in-depth study of Portal portal framework, the final choice of open source portal platform Jetspeed2 two development and implementation of content management, system integration and other functions, the construction of rural information service portal prototype, and verified. This paper takes the rural information service portal integration and Realization for information users, rural agriculture provides efficient, fast and convenient information service, has universal significance and high practical value of agricultural informatization construction in rural areas.
