Towards the relationship between Semantic Web and NLP

With the development of Semantic the Web technology, the NLP technology has much broader prospects. This article analyses the fusion degrees between the two technologies based on the survey of relations of them. We explain the relationship between Semantic Web and NLP in two aspects. One is NLP how to support Semantic Web development in Ontology Learning, Ontology Query and Multilingual Ontology Mapping. The other is Semantic Web technologies how to improve NLP results in Information Extraction and Word Sense Disambiguation. We also propose some research challenges for the cooperation between Semantic Web and NLP.
