New sources of world knowledge

I am trying to develop a natural language parser using a "knowledge intensive" approach. For this I need knowledge for my application. I have a few plans for amassing it:

• Various ontologies: Freebase, UMBEL, WordNet, FrameNet, VerbNet, DbPedia etc


• Using pattern matching on Wikipedia articles to extract info


• When trivially working, using the parser itself to extract more knowledge

For pattern matching I will need to develop patterns. Others have already done this, but I believe I can do even better. In wikipedia one can successfully use links to other articles as tokens as to simplify the structure of patterns when developing/evolving ones pattern to match against. Or at least I hope so.
