Abstract : The work on semantic networks involves three distinct areas: inferences, map displays, and English comprehension. The inference strategies implemented in SCHOLAR include different types of deductive, negative, and functional inferences. The graphics package allows users to ask questions and give commands in English to control SCHOLAR's map display, which is tied into the semantic network on South American geography. With partial support from this contract, we also developed an English Comprehension System, utilizing a data base on the ARPA network. Unlike geography, most questions about the ARPA network pertain to actions and procedures, which involve complicated English sentence structure, and hence necessitate sophisticated parsing and retrieval strategies. This report describes our work in each of these three areas. (Modified author abstract)
