If automatic speech processing wants to deal with spontaneous speech, it has to deal with disfluencies in general and speech repairs in particular as well. The paper describes the processing of speech repairs in the VERBMOBIL system and discusses the special requirements of real-time systems. With respect to this criterion, the VERBMOBIL approach and its results are compared to other work. All ...

This paper motivates and describes the thesis work that will be done as part of the author's Master of Engineering degree requirements. We present the primary thesis of the work: it is desirable, feasible, and practical to build a device for rapidly acquiring dense pose image datasets. Pose images are digital images tagged with estimates of the camera's 6 degreeof-freedom (DOF) position and ori...

The articles in this special issue represent advances in several areas of knowledge acquisition and knowledge representation. In this article we attempt to place these advances in the context of a fundamental challenge in AI; namely, the automated acquisition of knowledge from data and the representation of this knowledge to support understanding and reasoning. We observe that while this work d...

There has been an increasing interest, both of the research community and federal funding agencies in microblogs as a source of viable information for a variety of tasks. NIST (National Institute of Standards and Technology) has added a microblog retrieval track to TREC (Text REtrieval Conference) for the first time in 2011. NIST has selected Twitter as the source of microblog data. Twitter is ...

Statistical Spoken Dialogue Systems have been around for many years. However, access to these systems has always been difficult as there is still no publicly available end-to-end system implementation. To alleviate this, we present PyDial, an opensource end-to-end statistical spoken dialogue system toolkit which provides implementations of statistical approaches for all dialogue system modules....

One of the important features of ATM networks is their ability to support multicast communications. This facilitates the efficient distribution of multimedia information streams (such as audio and video) to large groups of receivers (potentially millions). Because ATM networks do not provide reliable delivery mechanisms, it is up to end systems to provide end-to-end reliability where it is need...

To solve the congestion problem in opportunistic networks, a congestion control strategy based on message deleting and transferring(DATM) is proposed. The congested node calculates the storage value of each message according to the forwarding probability and TTL of message, then deletes the message with the minimum storage value and transfers the message with the minimum forwarding probability ...
