Research on key technology analysis and system design of enterprise patent management system

Patent documents, the paper constructs a patent model tree and establishes a similar patent determination method based on vector space model and patent document features. The paper then proposes to use the patent application number as the association identifier, and associate the ontology and the ontology instance with the existing patent information database, which improves the speed of establishing the ontology and reduces the maintenance and update of the ontology. At the same time, based on the integration of existing workflow management and knowledge flow management, this paper proposes an integration framework with patent knowledge as the core knowledge and integration link, and describes the nature of knowledge retrieval and the method of importance differentiation. Finally, the paper designs a patent retrieval system, establishes the structural model and functional model of the system and the technical framework of the implementation system. On this basis, the design of the update module of the PMAS system is discussed. Finally, the performance optimization of the PMAS system is designed in detail.
