Subject: Fuzzy Logic as the "Brainware" of the Internet

Unlike classical logic, fuzzy logic is concerned, in the main, with modes of reasoning which are approximate rather than exact. In Internet, almost everything, especially in the realm of search, is approximate in nature. Putting these two facts
together, an intriguing thought merges; in time, fuzzy logic may replace classical logic in what may be called the brainware of the Internet. Actually, to a far greater extent than many of us, including myself had realized, fuzzy logic is already in
use in most major search engines. To get an idea, try the entry +fuzzy + search +engine ( + is conjunction) in excite. But this may be just beginning of a steep ascent in the use of fuzzy logic in the Internet. In this connection, Eli Snachez
brought to my attention the following qoate from Tim Bernres-Lee (Father of WWW); "... Toleration of inconsistency can only be done by fuzzy systems. We need a semantic web which will provide guarantees, and about which one can reason with logic. (A
fuzzy system might be good for finding a proof ..."

In my view, among the many ways in which fuzzy logic may be employed, there are two that stand out in importance.

The first is search. Another, and less obvious, is deduction in an unstructured and imprecise environment. Existing search engines have zero deductive capability. To convince yourself that this is the case, try the query "How many computer science
graduates were produced by European universities in 1999?" To add a deductive capability to a search engine, the use of fuzzy logic is not an option - it is a necessity.

To promote the use of Fuzzy Logic and the Internet, a Special Interest Group on Fuzzy Logic in the Internet (http://www.cs.berkeley.edu/~nikraves/bisc/sig/internet/) with Dr. Masoud Nikravesh as Chair, has been formed. Please contact Dr. Nikravesh
(nikravesh@cs.berkeley.edu) if you are interested in joining this SIG or posting your views and comments to the BISC Group.

Warm regards to all
