Design And Implementation Of Document Analysis System Based On Knowledge Graph

In scientific research activities,scientific researchers should have a comprehensive and accurate grasp of the current domain knowledge structure and development situation,so reading the literature extensively and grasping the content of the literature has become one of the key tasks of scientific researchers.At the same time,with the rapid development of today's social culture,education,science and technology,the number of documents recording its content has exploded,which has made it difficult for scientific researchers to obtain document information.With the informationization of the release of literature information,a large number of documents become relevant and convenient,but the analysis of the content of the literature still mostly relies on manual analysis.With the introduction of the concept of knowledge graph,its characteristics based on entities and relationships fit well with the literature network.Therefore,a system based on knowledge graph for automatic acquisition and information of documents meets the urgent needs of current scientific research.This article takes literature analysis as the research object,and uses knowledge graph as the basic research theory,and is committed to implementing a literature analysis system based on knowledge graph.From the perspective of literature analysis,the traditional literature analysis theory is combined with modern computer technology to realize the automatic acquisition and analysis of literature.This article focuses on the establishment and analysis of the knowledge map of the literature.On the one hand,it realizes the extraction of citation knowledge graph and author knowledge graph and the establishment of knowledge graph.On the other hand,it proposes related algorithms for literature analysis,such as ranking based on modern Internet.The Page Rank algorithm is used to design the document ranking algorithm,and the academic group reasoning algorithm is designed based on the community discovery algorithm.In order to design and implement a document analysis system based on knowledge graph,this article first introduces the background and significance of the research,and analyzes and introduces the current research status at home and abroad.Then the relevant information used in the system design is explained.After that,the typical business scenarios of the system are analyzed,and the functional and non-functional requirements of the system are organized and introduced;the key technical problems faced in the design and implementation of the system are explained,and the problem description and problem solving are described.The steps of the solution and problem algorithm implementation give the key problem solving process.Then,based on the requirements analysis,the overall design of the document analysis system is given.The overall architecture of the system,the division of system modules,and the interface design between the modules,the system Analysis and description of important functional processes;Later,in the detailed design and implementation of the system,the class diagrams and interfaces in each module,and the implementation of the system process are explained,and the implementation of the system is introduced in detail;finally,the completed system is designed Deploying,testing it according to the requirements analysis and analyzing the test results,so as to check and accept the system,proved that the overall design and implementation of the document analysis system is feasible and reasonable.
