    Abstract

    GRANT is an expert system for finding sources of funding given research proposals. Its search method-constrained spreading activation-makes inferences about the goals of the user and thus finds information that the user did not explicitly request but that is likely to be useful. The architecture of GRANT and the implementation of constrained spreading activation are described, and grant's performance is evaluated.
