Natural Language Processing (NLP)
A system that allows search engine users to type a question rather than keywords. There are a couple of ways to do this kind of processing. At the simplest level, the search engine simply removes the stop words in the question to leave keywords that are then processed as if it was a regular query. At the other end of the scale are very advanced systems that use statistics and linguistic analysis to accurately match documents to the user's question. The best-known example of this kind of approach is the AskJeeves (www.askjeeves.com) search engine.
