The majority of existing work on agent dialogues considers negotiation, persuasion or deliberation dialogues; we focus on inquiry dialogues, which allow agents to collaborate in order to find new knowledge. We present a general framework for representing dialogues and give the details necessary to generate two subtypes of inquiry dialogue that we define:(More)
A recent study suggested that human Cdc14B phosphatase has a central function in the G2 DNA damage checkpoint. In this study, we show that chicken DT40, human HCT116, and human telomerase reverse transcription-immortalized retinal pigment epithelial cells deleted for the Cdc14A or Cdc14B gene are DNA damage checkpoint proficient and arrest efficiently in G2(More)
We take a simple form of non-adversarial persuasion dialogue in which one participant (the persuader) aims to convince the other (the responder) to accept the topic of the dialogue by asserting sets of beliefs. The responder replies honestly to indicate whether it finds the topic to be acceptable (we make no prescription as to what formalism and semantics(More)
Current approaches to modelling plans and processes in AI are limited by current understanding of "goals" and "intentions". We discuss this question in a medical context, viewing goals as clinical objectives and plans and processes as collections of tasks to achieve those objectives. The specific context for this discussion is the CREDO project, which aims(More)
Logic-based argumentation offers an approach to querying and revising multiple ontologies that are inconsistent or incoherent. A common assumption for logic-based argumentation is that an argument is a pair Φ, α where Φ is a minimal subset of the knowledgebase such that Φ is consistent and Φ entails the claim α. Using dialogue games, agents (each with its(More)
It is often the case that agents within a system have distinct types of knowledge. Furthermore, whilst common goals may be agreed upon, the particular representations of the individual agents' views of the world that they operate within may not always match. In this paper we provide a framework to allow different agents with different expertise to make(More)
A strategy is used by a participant in a persuasion dialogue to select locutions most likely to achieve its objective of persuading its opponent. Such strategies often assume that the participant has a model of its opponents, which may be constructed on the basis of a participant's accumulated dialogue experience. However in most cases the fact that an(More)
