Detecting Forum Authority Claims in Online Discussions

This paper explores the problem of detecting sentence-level forum authority claims in online discussions. Using a maximum entropy model, we explore a variety of strategies for extracting lexical features in a sparse training scenario, comparing knowledgeand datadriven methods (and combinations). The augmentation of lexical features with parse context is also investigated. We find that certain m...

Graft tensioning during knee ligament reconstruction: principles and practice.

Failure to correctly tension grafts may overconstrain or underconstrain the knee, potentially predisposing the patient to deteriorating clinical and/or radiographic results over time. Knee ligament reconstruction requires a fundamental understanding of native anatomy, ligament biomechanics, and principles of graft tensioning. A successful strategy for graft tensioning takes into account the spe...

Spatiotemporal Aspects of Engagement during Dialogic Storytelling Child–Robot Interaction

The success of robotic agents in close proximity of humans depends on their capacity to engage in social interactions and maintain these interactions over periods of time that are suitable for learning. A critical requirement is the ability to modify the behavior of the robot contingently to the attentional and social cues signaled by the human. A benchmark challenge for an engaging social robo...
