Technical Report: Semantic Annotation Platforms
نویسندگان
چکیده
Semantic annotation is a key component for the realization of the Semantic Web. The volume of existing and new documents on the Web makes manual annotation problematic. Semi-automatic methods have been designed to alleviate the burden, and these methods have begun to be implemented with Semantic Annotation Platforms (SAPs). SAPs provide services that support annotation, including ontologies, knowledge bases, information extraction methods, APIs, and user interfaces. This chapter examines the considerations annotation systems must take into account, such document structure and initial ontology, and provides an overview of current SAP implementations. The Semantic Web also results in new as well as extended applications, such as concept searching, custom web page generation, question-answering systems as well as visualization. These applications are all made possible by the semi-automatic annotation services provided by SAPs.

متن کاملImproved Methods for Tagging and Semantic-Annotation for the Semantic-based OpenAPI Retrieval System*
The OpenAPI retrieval system has been developed applying semantic web technologies as the typical information retrieval method had. The semantic web technologies applied in the system are tagging and semantic-annotation. However, these methods are difficult for the non-technical general users to use. To solve these problems we suggest improved methods for the tagging and semantic-annotation. Ta...
