Domain Ontology Construction Method Research In The Web2.0Environment

In recent years, with the development of the global network, information resources add at analarming rate. The traditional unstructured information management relies mainly on the artificiallabel information object, thus it will unstructured information resources conversion and becomes (half)structured information resources. The traditional manual tagging needs to spend a lot of manpower,financial resources, and low efficiency. In addition, based on the Internet complex applicationenvironment, the needs of the user personalized, diversity and the characteristics of rapid change ismore and more obvious, but the mark methods can not meet the needs of more and more applications.We put forward a new kind of unstructured information management system, and also become thesuccessful key problems.The paper will use ontology construction and web2.0, combining the construction of domainontology by experts in the field of web2.0,which put up that domain ontology built be experts in thefield extend to the mass in the web2.0environment., playing group wisdom to realize the constructionof domain ontology.But web2.0successful application invariably emphasizes simplicity,the domainontology is not only complex structure,but also the build process is relatively complex,and whichreduces user’s enthusiasm.Thus, this paper will analyze the application needs of the domain ontology construction, thedomain ontology characteristics,the build process of the domain ontology as well as the descriptionmethod of the domain ontology in the web2.0environment.Simplify the structure of the domainontology and propose a new construction method and description,make this domain ontology maintainthe function of the ontology,but also has the simplicity.This paper will analyze the incentive systemproblems in the web environment,proceed to the needs of the public and build a set of incentives toattract the general public to actively participate in the domain ontology construction.The paper alsowill put forward the management issues in the web2.0environment,from three point of view of theuser,platform,and ontology,propose management mechanisms which can constrain the user behaviorand regulate the domain ontology,and thus improve the build quality of the domain ontology.Finally,the paper will builds a prototype system to build domain ontology in the web2.0environment to verify the feasibility and effectiveness of building domain ontology.
