摘要：
A computerized current awareness service for selective dissemination of information using Chemical-Biological Activities (CBAC), a Chemical Abstracts Service magnetic tape service, is described. The system, now four years old, includes 40 profiles containing terms, author names, and journal coden. Terms are assigned positive or negative numerical weights, relative to an arbitrary hit level. Right truncation of terms is allowed. In searching, the titles and abstracts from each biweekly CBAC tape are inverted and matched against the alphabetized list of words from all profiles. Hit documents are printed on 4- × 6-inch card forms. Precision of weighted word profiles as determined by feedback data and user reaction to abstract searching are discussed. © 1969, American Chemical Society. All rights reserved.
