There is a growing requirement for an internationally accepted system of recognition of measurement capabilities and relationships within and among countries, to facilitate seamless global commerce and trade. As a result, metrologists worldwide have recently developed increased interest in the concept and definition of traceability. Classically, traceability provides a way of relating the resul...

A human-in-the-loop simulation was conducted to evaluate advanced controller support tools and display enhancements in terminal airspace. Terminal-area air traffic controllers managed aircraft arriving on optimized profile descents along Area Navigation routes following runway arrival schedules using only speed clearances in the presence of forecast wind errors and other disturbances. Three suc...

Timeline generation is a summarisation task which transforms a narrative, roughly chronological input text into a set of timestamped summary sentences, each expressing an atomic historical event. We present a methodology for evaluating systems which create such timelines, based on a novel corpus consisting of 36 humancreated timelines. Our evaluation relies on deep semantic units which we call ...

We develop novel timeline interfaces which separate the events in timelines into threads and then allow users to select among them. This interface is illustrated with five threads describing the causes of the American Civil War. In addition to selecting each of the threads, the sequence of events it describes can be played. That is, the user can step through the sequence of events and get a des...

We present an approach to annotating timelines in stories where events are linked together by temporal relations into a temporal dependency tree. This approach avoids the disconnected timeline problems of prior work, and results in timelines that are more suitable for temporal reasoning. We show that annotating timelines as temporal dependency trees is possible with high levels of inter-annotat...

The construction of timelines of computer activity is a part of many digital investigations. These timelines of events are composed of traces of historical activity drawn from system logs and potentially from evidence of events found in the computer file system. A potential problem with the use of such information is that some of it may be inconsistent and contradictory thus compromising its va...

Timelines allow to represent temporally-rich information about plans as well as the current execution status of plans. Recent work has addressed the related issue of inferring timelines representing contextual information — often useful for informing planning and/or plan execution monitoring processes. The present article addresses the particular issue of inferring context from given models of ...

In this Perspective, we examine the portrayal of translational stem cell research in major daily newspapers in Canada, the United States, and the United Kingdom between 2010 and 2013, focusing on how timelines for stem cell therapies were represented before and after Geron terminated its pioneering stem cell program. Our content analysis reveals that press coverage has shifted from ethical, leg...
