This research discusses preliminary efforts to expand the coverage of the PropBank lexicon to multi-word and idiomatic expressions, such as take one for the team. Given overwhelming numbers of such expressions, an efficient way for increasing coverage is needed. This research discusses an approach to adding multiword expressions to the PropBank lexicon in(More)
The performance or handoff algorithm is critical to the overall system performance of cellular mobile communications. This paper presents a handoff algorithm that uses adaptive handoff values based on mobile location information and cell RF propagation statistics. Analysis is focused on the probability of hard/soft handoff and the probability of dropped(More)
IP-based networks such as the Internet have been the focal point for innovative technologies, services, and applications. These networks have enabled hugely successful services like the World Wide Web, and they are even attracting traditional services such as telephony. The service model for accessing Web content offers tremendous control and choice to(More)
PRISM is an architecture for distributing, storing, and delivering high quality streaming content over IP networks. In this paper we present the design of the PRISM architecture and show how it can support an enhanced set of streaming services. In particular, PRISM supports the distribution and delivery of live television content over IP, as well as the(More)
This paper describes the design and implementation of a low-cost projective immersive display (PID), called the Cave-let. A PID immerses the user in a computer-generated three-dimensional environment that responds to the user's movements. Current devices of this nature are very expensive, so that fewer than 100 units have been installed around the world. A(More)
This paper describes a distributed visualization of the operation of a reovirus. This visualization allows several groups of users at different locations to view how the virus behaves in normal and cancer cells. The users at each location can interact with the visualization and the other users. The techniques used to produce this visualization include the(More)
OBJECTIVE To determine the effect of standardized education specific to maternal resuscitation on nurses' confidence and competence during obstetric emergencies and to determine the cost savings associated with the program. DESIGN Pre- and postintervention surveys designed to measure perceived confidence and competence in resuscitation before and after(More)
We present the first corpus annotated with preposition supersenses, unlexicalized categories for semantic functions that can be marked by English prepositions (Schneider et al., 2015). That scheme improves upon its predecessors to better facilitate comprehensive manual annotation. Moreover, unlike the previous schemes, the preposition supersenses are(More)
