Annotation Method Of Component Information Based On Ontology

Component-based software development method is considered an effective way tosolve the software crisis. The component library is the infrastructure of this method.However, the size of a single component library can not meet the needs of softwaredevelopers, many heterogeneous interaction between the component library is notaccessible, the "component seeking" becomes very difficult.With the rapid development ofInternet, som component libraries providing commercial components and open sourcecomponents has appeared on the Internet,in addition, internet is also littered with a lot ofcomponents failed to be collected by a component library. In order to effectively retrievethese components, the information you need to mark these components, with a unifieddescription of the component model to describe them, so that users can effectively retrievethese components.Now, the main components are mostly descriptive model descriptive model based onfacets, but this facet description model to support semantic retrieval poor, and good bodysupport for semantics, it reduces the conceptual ambiguity and expression This paperpresents a description of ontology-based component model DCBO model. In DCBOmodel based on this paper, ontology-based annotation information component method,component body of information on the Internet through the mark, the conversion toDCBO model. Labeling method is based on this method to build a good body as aknowledge base, combined with grammatical dependencies of the components extractedtext tagging. This labeling method proved effective on the Internet component of the labelinformation.
