Schwartz, Eugene S.; And Others
The design, implementation and operation of the Computer Search Center of IIT Research Institute, an information center to educate and link industry and academic institutions to chemical and other scientific information systems, is described. Format conversion, profile input, search and output programs developed over a two-year period are detailed and storage requirements and program transferability are discussed. Linguistic analyses directed toward control of search terms, profile development and search effectiveness include a Key-Letter-in-Context index, term aggregation and a Least Common Bigram search technique. A graduate course in "Modern Techniques in Chemical Information" is outlined and experience in education and training for Selective Dissemination of Information (SDI), including profile preparation, is related. Relevance, output and cost statistics are presented from production searches of Chemical Abstracts Condensates. (Author)
