【摘要】：在21世纪经济发展过程中,知识所起的作用愈来愈大。企业知识伴随企业的发展壮大而积累沉淀,是企业不可剥夺的一笔重要财富。近年来,为了有效的管理企业知识,一种新型的企业管理方式正在逐步渗入到越来越多的企业,企业知识管理平台日趋成熟。这些平台能够高效的整合企业内部的各类知识,并能够利用搜索引擎快速搜索出与关键词和内容相匹配的资料信息,提供了海量的数据供用户参考,在一定程度上极大的方便了用户之间的共享。但是目前的知识管理平台还面临着一些问题。一是未考虑企业知识访问的安全性；二是尽管搜索引擎能够保证信息的查全率,却不能保证查准率。本文基于这两个问题开展研究工作,具体研究内容如下： 1)企业内部知识以各种载体存在于知识管理平台中,且大部分知识以文档格式存储。本文将在知识以文档存储的前提下,研究规划设计领域的文档分类,并梳理该领域的文档组织结构,便于后台存储及搜索。 2)基于企业的知识安全性考虑,本文采用基于角色的访问控制技术。系统中除了原有的用户和权限之外,增加了新的概念-角色,通过在用户和角色、角色和权限之间建立联系来确保企业知识的访问安全性。采用向角色赋予权限的方法,简化了系统中的权限管理。用户进入平台后,能够根据自己角色具有的权限访问相应的内容。 3)基于企业内部知识搜索准确性考虑,本文利用规则引擎的易用性和功能完备性,在研究和使用规则引擎的基础上,建立一套知识使用规则,提高查准率。论文基于上述三点实现一个基于角色访问控制和规则引擎的知识搜索系统。用户根据对应的角色登录系统,基于用户自身的角色以及用户搜索的关键字,结合规则引擎中的使用规则,向用户提供相对应的企业知识。
[Abstract]:In the process of economic development in the 21 st century, knowledge plays a more and more important role. Enterprise knowledge accumulates and precipitates with the development and growth of enterprise, which is an inalienable important wealth of enterprise. In recent years, in order to effectively manage enterprise knowledge, a new enterprise management mode is gradually infiltrating into more and more enterprises, and the enterprise knowledge management platform is becoming more and more mature. These platforms can efficiently integrate all kinds of knowledge within the enterprise, and can use search engine to quickly search the information matching with keywords and content, and provide huge amounts of data for users' reference. To a certain extent, it greatly facilitates the sharing between users. However, the current knowledge management platform still faces some problems. One is that the security of enterprise knowledge access is not considered, the other is that the search engine can guarantee the recall rate of information, but it can not guarantee the precision rate. Based on these two problems, this paper carries out research work. The main contents are as follows: 1) the internal knowledge exists in the knowledge management platform in various carriers, and most of the knowledge is stored in the document format. This paper will study the classification of documents in the field of planning and design under the premise of storing knowledge as documents, and comb the organization structure of documents in this field, so as to facilitate backstage storage and search. 2) considering the security of knowledge based on enterprise. This paper adopts the role-based access control technology. In addition to the original users and permissions, a new concept, role, is added to the system to ensure the security of enterprise knowledge access by establishing a relationship between users and roles, roles and permissions. The privilege management in the system is simplified by using the method of empowering the role. After entering the platform, the user can access the corresponding content according to the authority of his role. 3) considering the accuracy of knowledge search within the enterprise, this paper makes use of the ease of use and functional completeness of the rule engine. On the basis of studying and using rule engine, a set of knowledge usage rules is established to improve precision. In this paper, a knowledge search system based on role access control and rule engine is implemented based on the above three points. According to the corresponding role login system, based on the user's own role and user search keywords, combined with the rules of use in the rules engine, to provide users with the corresponding enterprise knowledge.
