Semantic Link Network Construction System Based On News Events

Semantic Web of Things is the overall structure of the six basic elements and the interrelationships of people,machines,things,networks,and time in the information ecosystem.Therefore,the things in SWoT are not only traditional On the material between the things,but the social network of things to things,things to people,people to people connected to the network.In the process of interconnection will produce many events.This article starts with the "things" and "net" in the SWoT,the dynamic real-time characteristics of the news events and the news events on the network are based on the hyperlink structure.The editor of the website is according to the individual's intention Linked to each other rather than an effective link,Causing users to often find their own news information incomplete,So the addition of semantic factors on the hyperlink after the expansion of semantic links to form a semantic link network news events related to the link to solve the problem.This paper first analyzes the present situation of semantic link network.On the basis of elaborating the theory and technology of semantic link network,this paper puts forward the framework of semantic link network construction system based on news events,and its semantic link network construction process is mainly(1)data collection,including web collection,analysis and storage,through a search engine for a large number of news events to collect;(2)Data preprocessing includes semantic element extraction,resource representation and association mining,mainly for the collection of semantic elements of the collected news events page,and using E-FCM to represent the semantic nodes of news events,and then mining based on association Algorithm to obtain the semantic link between semantic nodes;(3)The semantic link network based on news events is constructed.Then,the semantic link network construction system is analyzed and designed.The main modules are:data collection module,data processing module,semantic link network construction module and semantic link network operation module Finally,the main function modules of the system are realized and the related experiments are carried out on the traditional hyperlink network and semantic link network respectively.This paper designs and realizes the semantic link network construction system based on news events.Through the experimental and comparative analysis,we can see that users can use the semantic link network to improve the precision,recall rate and F value of the news events,so that the users can obtain a richer and more comprehensive The news information.The use of traditional hyperlinks to the network users often can not find the required information related to this issue.
