規(guī)劃設計領域的文檔模型及知識搜索的研究與實現(xiàn)
[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.
