Linguistic categories such as progressives, perfectives, tense and temporal adverbials are at the heart of our ability to describe events in natural language. Following on from the work of Moens and Steedman and the later work of Kent, we have identiied a fragment of an interval tense logic of Halpern and Shoham that is expressive enough to represent the temporal readings of many simple sentenc...

Portrayals of history are never complete, and each description inherently exhibits a specific viewpoint and emphasis. In this paper, we aim to automatically identify such differences by computing timelines and detecting temporal focal points of written history across languages on Wikipedia. In particular, we study articles related to the history of all UN member states and compare them in 30 la...

Space weather storms typically have solar, interplanetary, geophysical and societal-effect components that overlap in time, making it hard for students novices to determine cause-and-effect relationships relative timing. To address this issue, we use timelines provide context space of different intensities. First, present a timeline tabular description the great auroral last 500 years as an exa...

We present a visualization system that helps designers conceptualise interactions in a virtual environment (VE). We use eventcondition-action triads (triggersets) for specifying interactions, and provide multiple visualizations: sequence diagrams, floorplans and timelines. We present a two part study: sequencing VE interactions accurately and debugging mistakes. Subjects were divided into two g...
