Developmental Support of the Scientific and Technical Intelligence System.

摘要

This project has provided technical assistance to the development team of the Scientific and Technical Intelligence System (STIS) at Air Force Foreign Technology Division (FTD). The effort was directed at the design and documentation of several data structures and programmed capabilities of STIS. These included the following: (1) An Indexed-Sequential Access Method and Directory for encoding and decoding STIS user and system terms. (2) the data structure of a generalized STIS node which can serve for the elements of the STIS Concept Net, including entities, semantic elements (attributes and values), and derivation rules, and (3) a set of interpretations of the node structure and the definition of an approach which can be used by the analyst in representing intelligence information in the Concept Net, including source information, credibility, events, states, transitions, and general deductive rules.
