PertinenceMining.com is a French company that has a number of neat text processing products built on their KENiA or “Knowledge Extraction and Notification Architecture.” One their products is Connivences.info which produces maps of “actors” in the news with weighted lines to indicate relationships.
Another interesting tool is their Google + Pertinence Summarizer that enhances the results from Google with a “Summarize” button which splits the linked page into sentences and tries to rank their pertinence to the document so you can choose to see only the most pertinent. The interface took me a while – I’m not sure it works.
