A New Semantic Web Services to Translate HTML Pages to RDF

An extremely large number of Web pages in the Internet contain free texts in natural language that are only read by human beings. To be understood by machines, these pages should be annotated with semantic markups. Manually annotating large number of pages is an arduous work. This has made automatic semantic annotation an urgent challenge. In this paper, we propose machine learning based automatic annotation approach. This approach can be trained for different domains and requires nearly no manual rules.
