Interesting Question. I'm curious about Google vision of "linguistic" or "word game" technologies like:

• hit list clustering (e.g.: Vivissimo),
• text Summarization (e.g. Copernic Summarizer),
• translation (e.g.: Babelfish,
• Question answering (e.g.: TREC)..

Are these kind of technologies out of Google field of interest, are they under development or already in indexing techs but invisible for the user? Thanks!
