Title: Conceptual Spaces as a Semantics for Nonmontonic Reasoning

Abstract: First I will argue that nonmonotonic reasoning is mainly about the nomonotonicy of concepts, rather than the nomonotonicity of sentences. Then I shall present conceptual spaces as a tool for representing concepts. The central part of the talk will be to show that many aspects of nonmontonic reasoning can be explained if grounded in a conceptual space semantics.

Title: Uncommon Sense

Abstract: Using logic to formalize common sense was the topic of one of the first AI documents ever written (McCarthy 1959), and we now have over 45 years of progress to look back on. The view is not encouraging. We are still struggling to handle problems which young children find so trivial as to be below the horizon of conscious effort; and yet computers now routinely play superb chess, recognize faces, control spacecraft and solve challenging industrial-scale problems. AI is doing well, but "logical common sense" is stuck, I suggest, in a dead end, where progress is essentially stymied by old problems that should have been treated as warnings rather than as posing research goals to be solved. This paper attempts to diagnose what went wrong, and suggest some alternative ways in which the field might make better progress.

Accommodation and Travel

Special rates are available for the participants of CommonSense-05 at the following hotels in Corfu, both of which are a pleasant 10min walk from the symposium venue. You can make a reservation by contacting the hotel directly and quoting "CommonSense-05" to get the special rates.

Corfu is a popular destination in May and there are only limited rooms available, so please make your reservation as soon as possible. The following prices are valid only for bookings made before 22 April 2005.

Bella Venezia Hotel3 Stars60€72€+30-26610-46500belvenht@hol.gr

Regarding accommodation, apart from Cavalieri Hotel, there is an even better hotel (5 stars) called Corfu Palace Hotel, which is also about 15 minutes walk from the conference venue.

Corfu (or "Kerkyra") is one of the most beautiful Greek islands, located approximately 400km northwest of Athens. The capital of the island, where the Symposium will be held, is also called Corfu, while a number of pictorial villages are spread throughout the island. The day before our symposium starts, i.e. on the 21st of May, Corfu celebrates its unification with the rest of Greece (it took place in 1864) and there will be a lot of (mostly traditional) festivities that day.

One can reach the island by plane, or by boat:

Flying to Corfu

There are daily domestic flights to Corfu from Athens and Thessalonica. The airport is located 3 kilometres to the south of Corfu-city. During peak season there are also charter flights connecting Corfu directly with various cities in Europe.

Taking a Boat to Corfu

Upon arrival at Athens' airport "Eleftherios Venizelos", one can use the metro to get to the inter-city bus station, and then choose one of the following routes to Corfu:

Apart from Patras and Igoumenitsa, Corfu is also connected by sea with Italy (Brindissi, Bari, Ancona, and Venice).

Information


Symposium Venue - Faliraki

the symposium venue; address: Faliraki, Pyli Agios Nicolaos, Kerkyra (Corfu)

“Faliraki” is the popular name given to the St. Nicholas Baths complex , which was founded in Byzantine times. The Church of St. Nicholas , which was probably built in 1414 , forms part of this group of buildings. Following their renovation in 1995, the offices of the Municipal Development Enterprise (ANEDK) were relocated in the complex, which is also used for events such as conferences, seminars and exhibitions.

Faliraki is a pleasant 5 minutes walk from Spianada square (at the centre of Corfu town). Walking to the north along Kapodistriou Str, (which later becomes Eleftherias Str) you pass through an arch (part of the Palace of Saint Michael and Saint George) and after about two hundred meter you will see to your right the Agios Nikolaos Gate leading to Faliraki (right at the sea front).


Registration

We request all participants to pre-register by sending an email with name and affiliation to Pavlos Peppas no later than May, 9th, 2005.
