The DIPPER architecture is a collection of software agents for prototyping spoken dialogue systems. Implemented on top of the Open Agent Architecture (OAA), it comprises agents for speech input and output, dialogue management, and further supporting agents. We define a formal syntax and semantics for the DIPPER information state update language. The(More)
Spoken dialogue systems would be more acceptable if they were able to produce backchannel continuers such as mm-hmm in naturalistic locations during the user’s utterances. Using the HCRC Map Task Corpus as our data source, we describe models for predicting these locations using only limited processing and features of the user’s speech that are commonly(More)
In corpus-based robotics, the primitive functions built into a robot are determined by the functional content of human utterances spoken to the robot. In the example of route instructions treated in this paper, the 15 primitives found include functions such as turn(), cross(), landmark_is_located(), etc. These are natural primitives of human behaviour but(More)
Abst_~'act ~hrlication Categorial Gtmmnar (t/:G) combines the syntactic iu.,;ights of Categoria[ Grammar with the semantic insights of I)i;course Representation Theory. The addition of uni/ication to these two frameworks allows a simple account of intexaction be,.wcen different linguistic levels within a constraining, monostraml theory. The resulting,(More)
We explore the hypothesis that social media such as Twitter encodes the belief of a large number of people about some concrete statement about the world. Here, these beliefs are aggregated using a Prediction Market specifically concerning the possibility of a Swine Flu Pandemic in 2009. Using a regression framework, we are able to show that simple features(More)
The mapping between syntactic structure and prosodic structure is a widely discussed topic in linguistics. In this work we use insights gained from research on syntax-to-prosody mapping in order to develop a computational model which assigns prosodic structure to unrestricted text. The resulting structure is intended to help a text-to-speech (TTS) system to(More)
