Workshop “Argument Strength”

For the CfP for the special issue see below.

Arguments vary in strength. The strength of an argument is affected by e.g. the plausibility of its premises, the nature of the link between its premises and conclusion, and the prior acceptability of the conclusion.

The aim of this workshop is to bring together experts from the fields of artificial intelligence, philosophy, logic, and argumentation theory to discuss questions related to the strength of arguments. Such questions include:

Keynote speakers

  • Gerhard Brewka (University of Leipzig):
    Weighted ADFs
  • Dov Gabbay (Kings College, London; Ashkelon Academic College):
    Distortions in argument strength generated in the reasoning of sex offenders (Research with Gadi Rozenberg, Ashkelon Academic College)
  • Gabriele Kern-Isberner (TU Dortmund):
    A Plausibility-based Semantics for Defeasible Argumentation
  • Beishui Liao (Zhejiang University):
    Probabilistic argumentation and its computation — A survey
  • Henry Prakken (Utrecht University):
    Argument Strength and Probability

Venue and how to get there

Getting from Bochum Hauptbahnhof to the Ruhr-University Bochum

From Bochum Hauptbahnhof (central station) take the U35 towards Bochum Querenburg (Hustadt) and get out at stop “Ruhr Universität”. (Ticket needed: Preisstufe A, €2,60). On weekdays the subway U35 leaves every 5 minutes and reaches the university within 9 minutes.

Getting from the U-Bahn stop “Ruhr Universität” to Beckmanns Hof

On Wednesday and Thursday (November 30 and December 1) the workshop will take place at Beckmanns Hof, Ruhr-Universität Bochum, Germany. Beckmanns Hof is located on Campus behind the Mensa. A map of the campus can be found here: campus map.

From the train station of the U-35 (“Ruhr-Universität”) go up the pedestrian bridge, turn right from the exit and walk towards the university. Your route takes you directly to the building of the university library. Keep walking till you pass the University library on your right, and continue until you reach the University “Mensa” building. Pass by the “Mensa” by walking down stairs, cross a campus street and a parking lot, and further walk down to the Beckmanns Hof.

Travel recommendations for long-distance and air travellers

Bochum Hauptbahnhof (central station) is served by ICE, IC, EC, regional and suburban trains at a high frequency. From there, you can reach the University easily by taking underground line U35 straight to the stop Ruhr-Universität. Four airports - Dortmund, Münster/Osnabrück, Cologne/Bonn and Düsseldorf - are within a reasonable distance of the Ruhr-Universität. Düsseldorf Airport, however, is not only the largest, but also the most easily accessed: there are direct connections between the airport and Bochum’s main train station up to eight times per hour, and the journey only takes a good half an hour.

Getting from Düsseldorf Airport to Bochum Hauptbahnhof

Upon arriving at the airport follow the signs to the DB (Deutsche Bahn) train station. Buy your train ticket to Bochum (Ticket needed: Preisstufe D, €14,60) at the airport before boarding the monorail which takes you to the train station. There are trains travelling directly to Bochum Hauptbahnhof frequently and the trip takes about 35 to 45 minutes depending on which train you take. The ticket Preisstufe D is a ticket provided by the public transportation system VRR and it is only valid in regional trains and S-Bahn. If you take an ICE, IC or EC you need a more expensive ticket for long-distant trains.

Getting from Dortmund Airport to Bochum Hauptbahnhof

Take the shuttle bus from the Airport Terminal to Holzwickede train station. From Holzwickede you take the train to Dortmund Hauptbahnhof (central station) and then change trains to Bochum Hauptbahnhof.

Accommodation

Since both the city centre and the conference venues are easy to reach from there, we advise you to take a hotel close to Bochum Hauptbahnhof.
