Research On Some Key Technologies Of Enterprise Patent Management & Analysis System

With the support from the National Supporting Plan: Development and application of the digitized synthesis integration technology of the home electrical appliances industry(enterprise) , with the demanding of patent management & analysis from the enterprises in our country, several essential technologies and implementation methods has been researched in this dissertation. And also the research achievements are put into practice in a home electrical appliances group company.In the 1st chapter, the research background and significance of the dissertation is described. Patent management &analysis methods and it's applications, the deficiency in the existing patent management &analysis are reviewed and analyzed. Finally, main content and structure of the dissertation are given.In the 2nd chapter, the judgment methods of similar patents and correlation knowledge are descibed. Combine with the characters of the patent literature, this dissertation proposes a patent model tree, builds a jugment method based on the VSM and characters of the patent literature. Then the method of the correlation knowledge is described, including how to retrive the patent knowledge and othe knowledge, the classcification of knowledge and the initiative push of knowledge.In the 3rd chapter, patent retrieval technologies based on ontology is discussed. The patent description methods based on ontology and process of the patent retrieve ontology storehouse establishment are described. With Protege, the initial ontology storehouse can be established. And with fuel gas energy conservation, the example of establishing patent information ontology, the OWL language description are given. The patent application No. is taken as the connection to connect the ontology, the ontology instance and the existing patent information database. With this, the establishment of the ontology is expedited, the ontology maintenance and the renewal work is reduced. A self-organizations of relation ontology storehouse which can reduce the investment of the domain ontology experts and simultaneously cause the established ontology to suit the enterprise demands better is produced. Finally, a concrete retrieval process based on ontology matched with a corresponding graph is givenIn the 4th chapter, after studying the existing work flow management and the knowledge flows management integration, some deficiency is discovered. According to this deficiency, an integrated frame which takes the patent knowledge as the core knowledge and integrated joint is proposed. Also some descriptions to other knowledge properties and the importance discrimination method are made.In the 5th chapter, the design, development and realization of the PMAS system is discussed. Firstly, the demanding of the PMAS system is analyzed, then the system's structural model and function model as well as the realization system technical frame according to the demanding is established, grounded on this, the PMAS system's renewal module design is described, Finally a detail design explanation to the PMAS system's performance optimization is given.In the 6th chapter, the concrete applications of the patent management &analysis system in a enterprise is introduced. A detail elaboration to the PMAS system, separately from the retrieve of the patent information and additional in formations, the establishment of the patent special database, the retrieval of the patent information, including the retrieval of ontology, the establishment of the knowledge library in relative environments and the concrete applications of the on-line patent analysis system are carried out.In the 7th chapter, reviews the achievements and innovations of this dissertation, and gives a prospect for future work.
