Research And Implementation Of Distributed Multi-datasource Oriented Gri Doc Management System

In the scene of big data, there are a huge number of documents with different kinds. Besides processing data in ordinary way, it is important to extract and organize these data resources and convert them to information with generality, integrity and abstraction, which is called knowledge. Thus, it is necessary to organize and model knowledge-oriented data.Through the form of compound document, GriDoc System support users to organize and extract their valid information, which could be the big data of knowledge. In order to achieve a unified integration and management of various types of data. Based on the GriDoc Model proposed by Prof. Qi Deyu, this paper further study the architecture and implementation of GriDoc, and develop a distributed multi-datasource oriented GriDoc management system. The system could display and output the heterogeneous or multi-datasource document, support the remote synchronization of document, and integrate the function of full-text search, which implements the knowledge management.GriDoc management system implements the remote document synchronization with the technology of Java RMI, and uses lucene and mmseg4 j SDK to support the full-text search. This paper describes experiments and applications of functional modules, which proves the requirement and purpose of the design. The system working reliably and using easily, enables users to access and manipulate heterogeneous data in a uniform way, and helps to improve the work efficiency of documentation management.
