A Computer Aided Case Tool for Temporal Knowledge Visualization

The Internet has become a very important information source. Take Twitter for example: the tweets people post various kinds of data on the internet, usually with rich temporal and spatial aspects such as valid time, transaction time, location, and so on. In this paper we introduce a computer aided case tool alongside its theoretical underpinnings, for temporal knowledge visualization. It provides a user-friendly environment for describing scenarios with rich temporal information in natural language, which can be modeled in terms of Temporal Relationship Diagrams (TRD). The correspondence between sentences (and/or key phrases) in a given temporal scenario and the corresponding elements of the temporal relationship diagram can be automatically identified in a visualized way. From a temporal relationship diagram, the corresponding relative temporal relations and the equivalent "Meets" table can be derived automatically. A TRD can be automatically and visually transformed into its corresponding Time Graph, which is supported by an automatic consistency checker that delivers a visual and audio verdict as to whether a given scenario is temporally consistent or not.
