Darwin-FIRST Faq

What is a Thesaurus?
FIRST stands for Full Information Retrieval System Thesaurus, because it works centered on Thesaurus concept as expressed in Merriam - Webster Dictionary:

2a: a book of words or of information about a particular field or set of concepts; especially : a book of words and their synonyms; b: a list of subject headings or descriptors usually with a cross-reference system for use in the organization of a collection of documents for reference and retrieval

In FIRST we make distinction between Website Thesaurus that follows that description and Users’ Jargon Thesaurus closely related to the market served by each Darwin node. Effectively users “speak” via keywords. Its sequence in a user session is not dictated by the same semantics as in the “owners’ side”. In the owners’ side the reasoning follows established patterns along the Logical Tree, as they “think” in terms of subjects instead keywords. There is a subtle difference between these two concepts. Subjects are like “established” keywords pointing to specific themes within a given discipline meanwhile keywords are like magic keys able to open boxes with expected answers to our curiosity. Keywords are issued by users as in a strategic game to find answers to reduce their uncertainty, their ignorance. This is an interception game where users are stimulated to find answers as fast and economically as possible. So the sequence of keywords within a session has the meaning of chats oriented to open the Website content treasures. The order of frequently used keywords is not meaningful, because they guide users practically to the same result. This “Tarzan-like” chat could be screened in terms of n-ads, let’s say, monads, dyads, triads, …., n-ads, sets of one, two, three, n keywords respectively.
