On the other hand, our ability to process and absorb information remains limited, resulting in an exformation phenomenon, that is, a collection of unprocessed information for want of time and skill. Worse still, the increase in the volume of information can lead to focus reduction, a tunnel effect. Of course, many systems ara available to help locate documents through key words. Some, like Lycos, are remarkably effective, considering the wide volume they cover. However, this ease of access to documents obfuscates the difficulty of finding relevant information.
Analytical processing is unavoidable.
If the operation is not carried out before the documents are circulated, it has to be done by users who must keep resformulating their request and scan vast amounts of extraneous material to achieve a result that is not necessarily satisfactory. Both forms of document preparation have until now been carried out semi-manually by professionals, entailing substantial costs and delays. The expressions are arranged in ascending order from the shortest to the longest one. A hypertext-type interface makes it possible to navigate from one term to another and forward the selected term to the server's research module. In short, to allow for the consistent, faster preparation of documents by less skilled users, ICAS uses the techniques of uncertain reasoning, supervised learning, direct-handling graphic interfaces and automated processing of natural languages.
