Natural Language and Semantic Web

Been browsing on the Web for various tools in natural language processing (NLP) and natural language generation (NLG). Presently looking at cypher, heart of gold, gate, stanford parser, charniak parser, enju, opennlp, lkb, assert, halogen, kpml and a couple of others. Also looking at a couple of methods of storing structured knowledge from a parse including Berkeley's FrameNet ontology and some that came with halogen and kpml. Hoping to throw these tools at the Wikipedia dataset (9.74 gb) and post some results.
