Abstract : Documentation in two of the four areas of capability described in the project task structure was produced in the last quarter. Under input capabilities a plan for the empirical evaluation on procedures for automatic assignment was developed. The economics of descriptor usage, importance of ranking of descriptors and automatic corrective procedures were considered. Work in the latter areas is also considered a significant contribution to ultimate system integration. Query capabilities were considered from the standpoint of a fact retrieval system and the problem of developing a logic of questioning is discussed. These considerations provide a framework for the requirements of further developments in processing capabilities.
