vendor tool suggestion

NLP'ers

I was hoping that someone on this list may be able to help me.  I am looking 
for a vendor with software which allows the creation of knowledge and an 
engine for indexing and searching of documents.  In the healthcare field for 
example, I am familiar with www.landc.be and www.apelon.com. These vendors 
(generally) have developed their own healthcare ontology or taxonomy 
targeting medical records.  However, I am looking to target law enforcement 
incident reports; different ontology/taxonomy.  I would also like to find a 
vendor targeting the semantic web/W3C Standards.

Does anyone have a suggestion related to tools or vendors who have products 
available to develop non-healthcare applications?

I would like to be able to accomplish the following:

basic
- taxonomy (match against a set of synonyms)
- edit distance (these words within the same sentence or two)
- sentiment of the article

advanced
- disambiguate (are we talking about ford the car or ford the person)

Thanks in advance for any suggestions

regards,
Greg
