Classification in fact is an field of Artificial intelligence, more specific a
Natural Language Process sing. More than the current, buzz about "Semantic
Web", the field has had advanced considerably during the last 3 - 5
years period,
because an improvement on various techniques.

As Tim has indicated, IBM has been always on top of this research
involving NLP. This past week was announced how their voice
recognition software does not need user training a breakthrough for
this type of commercial applications.

I am very interested in the NLP area. I consider Tim's idea a very
current and important one. Given the incredible amount of scientific
information on the web, and the amount that is inputted constantly,
the problem of classification and retrieval of this information seems
vital.

Having smart systems that can search for this information, classify
and stored them, will be right there with the idea of literate papers
that can be found and added to the system. I will be more interested
in a system that can find the information and create a literate
document from it. As Tim said, this kind of systems perform better
when they are domain specific.
