ARG:dundee

Argumentation Research Group

OVA alpha now available

The group has been working on some tools that help with the analysis of argument, but that have a very low barrier to use. The first result is OVA (Online Visualisation of Argument) which is an online Flash tool for analysing arguments in web pages. In some ways it is similar to Araucaria, though it is not as sophisticated. It can also generate AIF analyses, and can save them to ArgDB. Both AIF and ArgDB form cornerstones of the the EPSRC-funded project Dialectical Argumentation Machines which aims to build the infrastructure required for the World Wide Argument Web.

OVA’s home page is here, and an alpha version of OVA is available for general use at http://ova.computing.dundee.ac.uk. We are keen to hear your feedback: please do contact Chris, Simon or Mark.

Simon’s CMNA9 Presentation: Argument Blogging

Simon gave a presentation on the Argument Blogging project to CMNA 9 held at IJCAI in Pasadena recently. As described in a previous post argument blogging is the process of harvesting textual resources from the WWW and structuring them in terms of argumentative dialogues. The aim is to support distributed dialogues occuring online and to capture those interactions in a form that can be reused.

  • Abstract: “Argument Blogging is the process of harvesting textual resources from the web and structuring them into distributed argumentative dialogues. This paper introduces a prototype software system for performing argument blogging and storing the resultant dialogues so that they can be analysed and reused.”

SICSA PhD Masterclass in Logics of Argumentation

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


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

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.

Two vacancies for research assistants

The group’s new, EPSRC-funded Dialectical Argumentation Machines project is recruiting its research assistants. The advertisements for the first and second posts are now available.

Henry Prakken, SICSA Distinguished Visitor

Henry Prakken

Prof. Henry Prakken from the Universities of Utrecht and Groningen in the Netherlands will be a SICSA Distinguished Visitor with ARG:dundee for the month of July 2009. Over that period, we will be exploring models that combine different theories of argumentation. He will also be delivering talks at Dundee, Aberdeen and Edinburgh and offering a PhD workshop.

Online Visualisation of Argument

This is Mark Snaith presenting his senior honours project entitled “Online Visualisation of Argument” at the annual School of Computing degree show at the University of Dundee [ Download: xvid avi format (47.6 MB) ]. The main aim of this project was to provide a simple way to visualise arguments online using a flash widget to graphically render Argument Interchange Format (AIF) resources. Mark is spending the summer working with ARG:dundee to further develop the OVA software suite.

Argument Blogging

Here is a short film [ Download: xvid avi format (26.2MB) ] of Colin Gourlay talking about his honours project at the School of Computing 09 degree show. Colin has been working in the ARG group on the argument blogging project which captures argumentative dialogues that occur online and records them using the Argument Interchange Format. Simon will be presenting a paper describing some of the work on this project during CMNA 9 at IJCAI in July.

Guillermo Simari visiting

Prof. Guillermo Simari from the Department of Computer Science & Engineering at the Universidad Nacional del Sur in Bahia Blanca, Argentina is visiting us today. He will be delivering a seminar entitled Modeling the Accrual of Arguments in Defeasible Logic Programming at noon in Wolfson. All are welcome.
