The Modeling Method And Implementation Of Communication Education Knowledge Network

With the continuous improvement of the level of informationization construction,the size and capacity of various kinds of the structured,semi-structured and unstructured types of management and technology data in the current communication education institutions are increasing rapidly.However,while the knowledge resources in various fields are developing rapidly,the problems such as the restriction of management system,the explosion of educational data,the shortage of technical means,the shortage of technical manpower,the lack of standard and specification,the dispersion of data management,the singleness of data type and the lower application level are becoming more and more outstanding,various in-use and under-construction software systems and databases have gradually become "isolated information islands",which leads to the inefficient use of these knowledge resources,and far from forming an efficient knowledge network.In the era of big data,the effection of knowledge resources for communication education becomes more and more prominent,and the knowledge network has become an important platform to support the sustainable development communication education institutions.As a result,the implementation of knowledge management has become an urgent problem.The main objective of this thesis is to apply knowledge network based knowledge management technologies to communication education processes,and form communication education knowledge network,so that from which all kinds of users can acquire knowledge resources accurately.This thesis analyzes the research background and significance,and determines the research framework and key technologies.The main research works of this thesis are as follows:Firstly,this thesis defines the structure model of communicaton education knowledge network.From the perspective of building business architecture,data architecture,application architecture and technology architecture,a 6-layer architecture model based on the TOGAF architecture model is presented.It includes user layer,application layer,model layer,presentation layer,resource layer and facility layer.Based on the actual situation of a communication colledge,this thesis constructes the business management architecture,the knowledge resoures architecture and the knowledge application architecture.This thesis analyzes the operation mechanism of communicaton education knowledge network,presents a kind of implementation process model from the construction requirement,the management system design,the knowledge resourcesacquisition and creation,the knowledge resources system distribution and management and the knowledge network operation and feedback processes.Secondly,this thesis presents a knowledge resource network modeling method based on knowledge points correlation,analyzes the composition,aggregation,generalization,dependence,realization,association and other relationships between the knowledge resources in the knowledge network,and then establishes a multi-relationship model of communication education knowledge hypergraph.Based on the Dublin Core classification method and XML technology,this thesis researches and designs the commucation knowledge resources meta-information modeling methods and knowledge resources object architecture model.Based on the management requirements of the commucation education knowledge resources,this thesis researches and designs the organization modeling,process modeling,permission modeling methods.Based on the knowledge retrieval and recommendation requirements,this thesis improves and optimizes a hierarchical retrieval model based on knowledge map and a top-N knowledge recommendation model based on feature word association rule analysis.At last,this thesis validates the models and methods.This thesis designs a demo-version software of the communication education knowledge network management system,and the development is realized by using software engineering methods.An example validation is given to verify the existing information resources of a communication education organization.The validation results show that the communication education knowledge network modeling methods satisfies the actual requirements and achieves the design requirements of this thesis.
