A CASE STUDY OF The UNITERM INDEX TO US CHEMICAL PATENTS USING A WEIGHTED TERM SEARCH TECHNIQUE Available to Purchase

The phenomenon of a rapidly increasing volume of technical literature is well known. The cost and time involved in the intellectual indexing and classification of much of this literature is uneconomic. A lowering of indexing standards and free text searching is being forced upon us. Computer applications and techniques are being devised to turn cheap and crude input into an acceptable level of output. This paper describes the application of such a technique and evaluates the search results. The search was conducted on the Uniterm Index to US Chemical Patents, issued by Information for Industry Incorporated, known as IFI.
