Understanding human-computer interactions in map revision

Abstract. Tracking, parsing and modeling human-computer interactions to edit, revise documents is difficult but necessary if we are to develop automated technologies that will aid or replace humans. This paper introduces a system for accessing and recording a stream of events related to human actions in a real-time map (cartographic) revision system. The recorded events are parsed into a sequence of meaningful user actions and an action representation in XML format is generated. Further, we report results of experiments on predicting user actions such as view changes, edits, road tracking/production using a Hidden Markov Model
