Statistical language models play a ma jor role in current speech recognition sys tems Most of these models have fo cussed on relatively local interactions be tween words Recently however there have been several attempts to incorpo rate other knowledge sources in par ticular longer range word dependencies in order to improve speech recognizers We will present one such method which tries to autom...

In this paper we address the problem of topic classification of speech data. Our concern in this paper is the situation in which there is no speech or phoneme recognizer available for the domain of the speech data. In this situation the only inputs for training the system are audio speech files labeled according to the topics of interest. The process that we follow in developing the topic class...

Web service composition is currently a very focused-on topic of research, with many studies being proposed by academic and industrial research groups. This paper discusses the design and verification of behavior of composite Web services. We model composite Web services based on two behaviors, namely control and operational. These behaviors communicate through conversation messages. We use stat...

Hydrologic processes in the pinyon-juniper woodlands of the western region of the United States are variable because of the inherent interactions among the occurring precipitation regimes, geomorphological settings, and edaphic conditions that characterize the ecosystem. A wide range of past and present land-use practices further complicates comprehensive evaluations of these hydrologic process...

We explore automated discovery of topicallycoherent segments in speech or text sequences. We give two new discriminative topic segmentation algorithms which employ a new measure of text similarity based on word co-occurrence. Both algorithms function by finding extrema in the similarity signal over the text, with the latter algorithm using a compact support-vector based description of a window ...

to evaluate off-label and off-nccn guidelines uses of antineoplastic drugs in a major chinese hospital.totally 1122 patients were selected from july to december 2011. then, the off-label and off-nccn guidelines uses of antineoplastic drugs were analyzed.in 798 of 1122 patients (71.12%), drugs were used for off-label. in 317 of 1122 patients (28.25%), the drugs were prescribed for off-label and ...

Biological switches must sense changes in signal concentration and at the same time buffer against signal noise. While many studies have focused on the response of switching systems to noise in the ON state, how systems buffer noise at both ON and OFF states is poorly understood. Through analytical and computational approaches, we find that switching systems require different dynamics at the OF...
