Manual and automatic semantic annotation of web documents
José Luis Navarro-Galindo, José Samos · 2010
In this paper, FLERSA (Flexible Range Semantic Annotation) is presented as a user-centred annotation tool for Web content. The tool has been developed over a CMS and allows both manual and automatic semantic annotations. For manual annotation, a new flexible range markup technique is used, based on the RDFa standard, to support the evolution of annotated Web documents more effectively than XPointer. For automatic annotation, a hybrid approach based on natural language processing (NLP) techniques (Vector-Space Model + n-grams) is used to determine the concepts that the content of a Web document deals with (from an ontology which provides a taxonomy), based on previous annotations that are used as training Corpus.
