dc.description.abstract | This report describes the Analyst's Assistant, a software system for language-interactive, collaborative user-system interpretation of events, specifically targeting vehicle events that can be recognized on the basis of vehicle track data. The Analyst's Assistant utilizes language not only as a means of interaction, but also as a basis for internal representation of scene information, background knowledge, and results of interpretation. Building on this basis, the system demonstrates emerging intelligent systems techniques related to event recognition, summarization of events, partitioning of subtasks between user and system, and handling of language and graphical references to scene entities during interactive analysis. | en_US |
