Research On The Description And Analysis Method Of Cyberspace User Resources

With the continuous update and development of Internet technology,the cyberspace information resources are constantly changing in the digital form.Various information resources make people obtain more detailed information through the network technology.However,the current organization and management of information resources cannot keep up with the digitization and network development of resources,and it is difficult to meet people's various demand for information resources.As an important part of cyberspace information resources,cyberspace user resources have the features of scattered distribution,different manifestations,large number of resources and rapid growth,which increase the difficulty of sharing and exchanging user resources.In this context,the standard and effective description and analysis of the content and form of the cyberspace user resources make it possible for the user resources to be efficiently circulated and used,which is an urgent problem to be solved in the current information resource sharing and information services.At the same time,the repetitive and anonymity of identity information in user resources also brings many hidden dangers to network security.In the security field,bad elements may use multiple accounts for malicious behavior,and the similarity of user identity can correlate user identity and reduce network security risk.It can also provide user analysis and decision support in the business field,.Therefore,this paper studies the description method and analysis of cyberspace user resources and the main research work includes the following points:1.According to the description and feature of cyberspace user resource,this paper proposes a description method of user resources based on ontology and metadata.introduces an ontology description method based on the metadata description method,describes the relation between attributes and concept of metadata,and describes the description framework and a description method of ontology and metadata.2.According to the analysis of user resources,this paper mainly from the similarity discrimination of user identity to expand the user resources analysis,put forward a method based on the username features greedy matching to discriminate the similarity of the identity.This paper firstly describes the similarity of user identity and then the username is counted according to the features of length,special characters,numericcharacters,English characters and character combination patterns from the data set,each feature is divided into intuitive and contrastive aspects,from the intuitive point of view to analyze the importance of features,from the aspect of comparison to analyze the feature's similarity of username pairs.The similarity of username feature vector is combined with the comparison of threshold value to verify whether different username belong to the same person,and to search and discriminate the username belonging to the same people in the data set.
