A lightweight approach to semantic tagging

Semantic Annotation is a challenging research direction in the area of Semantic Web. Turning the web into a Semantic Web implies widespread semantic annotation of documents. But it is still need to be investigated further in order to make annotation process more efficient, automating it as far as possible. The approach described in this paper aims at semi-automatic semantic tagging by application of linguistic lightweight methods for extraction of relevant concepts and by defining appropriate semantic models.
