In this paper we tackle a unique and important problem of extracting a structured order from the conversation a customer has with an order taker at a restaurant. This is motivated by an actual system under development to assist in the order taking process. We develop a sequence-tosequence model that is able to map from unstructured conversational input to the structured form that is conveyed to...

Silence is an integral part of the most frequent turn-taking phenomena in spoken conversations. Silence is sized and placed within the conversation flow and it is coordinated by the speakers along with the other speech acts. The objective of this analytical study is twofold: to explore the functions of silence with duration of one second and above, towards information flow in a dyadic conversat...

The dynamical processes taking place on a network depend on its topology. Influencing the growth process of a network therefore has important implications on such dynamical processes. We formulate the problem of influencing the growth of a network as a stochastic optimal control problem in which a structural cost function penalizes undesired topologies. We approximate this control problem with ...

The ability to reach out and engage learne...

This article is based on an exploratory study on the use of blogs to support learning in an online MBA school. In this paper, the authors examine students’ perceptions toward blogs and their effectiveness. The study finds that although students are open to the idea of using blogs to enhance presentation and reflection of their learning, concerns exist on their suitability for threaded discussio...
