摘　　要： 将智能AGENT应用于图书管理信息系统,以提高它的个性化服务水平是该文的主要目的.该文在深入分析当今图书管理信息系统的发展水平和趋势,以及现有个性化信息服务技术和研究应用现状的基础上,把智能AGENT技术应用于图书管理的个性化服务上,探讨了新的系统结构模型和编程模式.并对个性化检索、用户兴趣特征学习和检索信息过滤等关键技术进行了研究.该文构造了一个多AGENT系统(MAS),各子系统既相互联系又相互独立,可以就每一子系统涉及的技术分别加以研究和实现.此MAS工作于一个现有的图书数据库系统基础之上以提高它的个性化服务水平,MAS通过一个接口将用户的检索要求转化为现有系统能够执行的检索条件并进行检索;另外,它将查询来的结果按照系统学习的用户个性化特征表过滤后推送给用户.系统按照用户兴趣、查全和查准图书信息,这种能力取决于用户AGENT对用户兴趣的学习和储存于用户个性化特征表中用户兴趣信息的完备和准确程度,而用户特征信息表的完备性和准确性随着系统学习用户兴趣的积累和深入而不断提高.该文通过用户的检索历史和输入的个人信息作为学习用户兴趣的起点,经过学习和用户对系统推荐信息的反馈评价反复进行使得系统的学习与用户的兴趣越来越接近.系统计算用户检索关键词之间的关系,将关键词组合成一些检索语,并结合时间因素和使用频度的变化赋予这些检索语不同的权重,然后按照权重的高低排序推送经过滤后的系统检索查询信息给用户.该文利用智能AGENT技术根据用户的兴趣主动学习搜索图书信息,按照学习的用户兴趣过滤推送给用户,从而实现图书管理信息系统的个性化服务水平.在此基础上为用户开展个性化检索、个性化用户界面定制、图书管理用户个性化服务定制等一些个性化服务,提高了用户使用图书馆资源的效率,降低了时间消耗,较好的避免了'信息海洋'和'资源迷向'的副作用.研究实践表明,该文的个性化服务的实现方法能够有效的降低系统开发和技术实现的复杂性,能够比较准确的掌握用户的兴趣并为他们提供满意的服务. The central purpose of this paper is applying intelligent agent in Book Management Information System /(BMIS/) to enhance its individual service function. The paper study a new system structure and new programming model based activity of nowadays' individual service technology and application in BMIS. The paper study individual searches, learning of user' s interest and information filtration The paper conform a multi-agent system /(MAS/) . It plays on the basic of a relation database by a interface which can transfer user' s searches requirement to searches term accepted by a intrinsic relation database. It pushes searches results to user what was compared and filtrated by user interest table. The ability of query according to user' s interest lies on the veracity and maturity of user agent learning user' s interest It learning user' s interest by the way of user searches action and user' s evaluation to system recommending information results. System study the relation among query keywords It assembles keywords to some query term which reflect user' s interest. It calculates the weight of query term integrated query time and frequent. At last it pushes and sorts query results to user what filtrated according to how many weight the query term is. The system which it was developed according to the theory and method of this paper searches and push query information by user' s interest, in order to enhance the individual service function of system. It provides individual searches, user interface customization, individual service customization of book management. It can improve the efficiency of user using library. It indicates the theory and method of the paper can reduce the difficult and complexity of system development and technology realization. It can learn user' s interest and provide famous individual service.
