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:
- Which factors influence the strength of an argument?
- What are the pros and cons of different formal representations of argument strength?
- How to formally model qualifiers on the conclusions of arguments?
- How does argument strength propagate when inferences are chained?
- How do arguments accrue?
- Can weaker arguments defeat and/or defend stronger arguments?
- When do more specific arguments defeat more general arguments and vice versa?
- How do formal and informal approaches to argument strength relate?
- How do preferences assigned to premises influence the evaluation of arguments?

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.
Getting from the U-Bahn stop “Ruhr Universität” to the SSC building
On Friday (December 2) the workshop will take place in the building called SSC, which is located on Campus as well. See also the campus map.
From the train station of the U35 (“Ruhr-Universität”) go up the pedestrian bridge, turn right from the exit and walk towards the university. Turn left before the first building on your left, then walk straight towards the SSC building.
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.
The workshop is organised by the Research Group on Non-monotonic Logic and Formal Argumentation at the Faculty for Philosophy II, Ruhr-University Bochum. http://homepage.ruhr-uni-bochum.de/defeasible-reasoning/
The workshop is supported by the Sofja Kovalevkaja award of the Alexander von Humboldt-Foundation (funded by the German Ministry for Education and Research) and by the Ruhr University Research School PLUS (funded by Germany’s Excellence Initiative [DFG GSC 98/3]).
