This paper presents a dialogue system in the form of an ECA that acts as a sociable and emotionally intelligent companion for the user. The system dialogue is not task-driven but is social conversation in which the user talks about his/her day at the office. During conversations the system monitors the emotional state of the user and uses that information(More)
This paper describes an initial prototype demonstrator of a Companion, designed as a platform for novel approaches to the following: 1) The use of Information Extraction (IE) techniques to extract the content of incoming dialogue utterances after an Automatic Speech Recognition (ASR) phase, 2) The conversion of the input to Resource Descriptor Format (RDF)(More)
1. APPLICATION DOMAIN The Senior Companion (SC) is a fully implemented Windows application intended for intermittent use by one user only (a senior citizen) over potentially many years. The thinking behind the SC is to make a device that will give its owner comfort, company, entertainment, and some practical functions. The SC will typically be installed at(More)

This paper discusses a planner of the semantics of utterances, whose essential design is an epistemic theorem prover. The planner was designed for the purpose of planning communicative actions, whose effects are famously unknowable and unobservable by the doer/speaker, and depend on the beliefs of and inferences made by the recipient/hearer. The fully(More)
Multimodal conversational dialogue systems consisting of numerous software components create challenges for the underlying software architecture and development practices. Typically, such systems are built on separate, often pre-existing components developed by different organizations and integrated in a highly iterative way. The traditional dialogue system(More)
This paper presents an alternative to the 'speech acts with STRIPS' approach to implementing dialogue: a fully implemented AI planner which generates and analyses the semantics of utterances using a single linguistic act for all contexts. Using this act, the planner can model problematic conversational situations, including felicitous and infelicitous(More)
We present an Embodied Conversational Agent (ECA) that incorporates a context-sensitive mechanism for handling user barge-in. The affective ECA engages the user in social conversation, and is fully implemented. We will use actual examples of system behaviour to illustrate. The ECA is designed to recognise and be empathetic to the emotional state of the(More)
This paper focuses on the use of a natural language analytics engine to provide feedback to students when preparing an essay for summative assessment. OpenEssayist is a real-time learning analytics tool, which operates through the combination of a linguistic analysis engine that processes the text in the essay, and a web application that uses the output of(More)
