Attempts to make online searching more effective by concentrating on key
words often come a cropper. Is that penguin you are interested in a bird, a
publisher or a biscuit, for example? Now Autonomy, a company based in Cambridge,
has devised a system that analyses whole sentences, so it’s much more likely to
send you in the right direction. Called ActiveKnowledge, the software runs in
the background as you work in other programs, continually dredging up relevant
information just in case you need it.
