Liz Black visiting

Posted by chris on February 10, 2010

Liz Black who is currently at the University of Oxford working in the COSSAC group, is visiting us today. She is delivering a seminar:

Agreeing how to act

When deliberating about what to do, an autonomous agent must generate and consider the relative pros and cons of the different available options. The situation becomes even more complicated when multiple agents are involved in a joint deliberation, as each agent will have its own preferred outcome and this may change as new information is received from the other participating agents. This talk considers such joint deliberation through the use of argumentation techniques.

I will present a dialogue system that allows agents to come to an agreement about how to act in order to achieve a joint goal. During such a dialogue, an agent can use its perception of others in order to select arguments that it believes are likely to be particularly persuasive. I will discuss how an agent may develop a model of what is important to another agent and how it can then use this model to guide its dialogue behaviour.

The seminar will be in Wolfson as usual at noon.

Katarzyna Budzyńska joins ARG

Posted by chris on October 2, 2009

We are delighted to welcome Katarzyna Budzyńska to ARG for a year from today. Katarzyna is Assistant Professor of Logic at Cardinal Stefan Wyszyński University in Warsaw, where she is coordinating the development of a Polish research community in argumentation. She also contributes to the PERSEUS project, which is focusing on developing links between computational models of argument and rhetorical and psychological models of persuasion. It is this work that she will be developing whilst resident at ARG:dundee.

Katarzyna maintains her homepage at http://argumentacja.pdg.pl/budzynska.

SICSA PhD Masterclass in Logics of Argumentation

Posted by chris on July 28, 2009

Our SICSA Distinguished Visitor, Henry Prakken, is delivering a masterclass today aimed at PhD students on the topic of Logics for Argumentation. We will be meeting from 1pm to 4pm in the seminar room in the School of Computing.

In recent years, argumentation has become an increasingly popular topic in
the symbolic study of commonsense reasoning and inter-agent communication.
In logical models of commonsense reasoning, the argumentation metaphor has
proved to overcome some drawbacks of other formalisms. Many of these have
a mathematical nature that is remote from how people actually perceive
their everyday commonsense reasoning, which makes it difficult to
understand and trust the behavior of an intelligent system. The
argumentation approach bridges this gap by providing logical formalisms
that are rigid enough to be formally studied and implemented, while at the
same time being close enough to informal reasoning to be understood by
designers and users. In the current course the fundamental concepts and
structure of argumentation logics will be discussed.

Henry Prakken’s ARG seminar

Posted by chris on July 22, 2009


Our SICSA visitor, Prof. Henry Prakken, is delivery a seminar today entitled, “Sense-making software for fact finding in law“. We will be in Wolfson at noon as usual. Henry will also be leading our weekly reading group session this afternoon.

Adam Wyner visiting

Posted by chris on July 15, 2009

Adam Wyner, from London, who is working with folks at UCL and Liverpool, amongst others, and who has PhDs both in linguistics from Cornell and also in computer science from Kings, is visiting us today. He will be speaking on “From Arguments in Natural Language to Argumentation Frameworks” at 1200 in the seminar room.

Helena Lindgren visiting

Posted by chris on April 22, 2009

Helena Lindgren from the Computer Science Department at the University of Umeå is visiting the group this week to find out more about what we have been doing, and to kick off a collaboration for which she has won funding from VINNOVA, the Swedish funding council. Helena has experience of building decision support systems in healthcare, with prototypes running in Sweden, Korea and Japan, and she is now working to integrate argumentation structured around AIF representations into those systems.

Bart Verheij visiting

Posted by simon on November 19, 2008

 

Bart Verheij, from the AI department at the University of Groningen is visiting us for a couple of days. He is delivering a seminar on Waking Up from the Logical Dream, Or: Argumentation as a Content-Driven Activity at 12 noon today in Wolfson.

Waking Up from the Logical Dream, Or: Argumentation as a Content-Driven Activity – Bart Verheij

Imagine yourself being in court, having to defend your innocence of a serious crime. Let’s suppose that your defense fails, and you end up behind bars. Was it your – probably imperfect – control of the logic of argumentation that made you lose? Or, was the problem more a matter of content, for instance, your unconvincing alibi, or lack of knowledge of the law?

This talk will use the recent advances in the logic of argumentation as a starting point, continuing to the hard issue of understanding how much logic is helpful for argumentation. In the talk, the issue is addressed from the perspectives of argumentation software and of argumentation schemes. It will become clear that Toulmin’s research agenda (dating from the 1950s) is still relevant.

Andrew Ravenscroft visiting

Posted by simon on October 1, 2008

Prof. Andrew Ravenscroft from the Learning Technology Research Institute at London Metropolitan University is visiting the group today. He will be delivering a seminar entitled, The thinking web? Designing tools and mashups for cyber-argumentation today at 12 noon in Wolfson.

This talk will review over a decade of design-based research that has: investigated the relationship between argumentation and thinking in learning contexts; and, designed digital tools that model argumentation and support its practice. This Learning Sciences approach to learning interaction design centres around the notion of ‘dialogue games’. This is a paradigm that can be used analytically or prescriptively to further or understanding of dialectical dialogue processes and how these can be

modelled and promoted for educational purposes.

The talk will emphasise: our work in applied computational linguistics that originally investigated and modelled educational argumentation; the design and evaluation of deployable dialogue game tools, on a relatively large-scale, that arose out of the computational modelling; and, present

our ongoing work that is synthesising dialogue game technologies and ideas with SOA and social software approaches – to realise accessible and widespread mashups, or ‘eco-systems’, for cyber-argumentation.

Finally, I will reflect on and open up the discussion about where this work might be taking us in terms of future web-technologies and related digital practices, reflecting on questions such as “What sort of

thinking do we need, by man and machines, in the 21C?”
