20th International Workshop on
Description Logics

Brixen-Bressanone (near Bozen-Bolzano), Italy
8-10 June 2007


Call for Papers

The 2007 edition of the DL workshop will take place from the 8th to the 10th of June 2007 in Brixen-Bressanone (near Bozen-Bolzano), Italy. This is 80 Km south of Innsbruck (where the ESWC-07 conference will take place immediately before); direct train connections run every hour between Innsbruck and Brixen-Bressanone. Arrived this year to its 20th edition, DL is the major annual event of the description logics research community. The workshop is thought as a gathering forum to meet, discuss and exchange experiences among all those, both in the academy and industry, who are interested in description logics and in all their broad range of applications.
Participants in the workshop will enjoy the invited talks by: Moreover, Ron Brachman and others will join us for a special event to celebrate the *20th* edition of the Description Logics workshop!
Students with accepted papers may apply to grants supporting travels within Europe (300 EUR) or from outside Europe (500 EUR).

We invite contributions on all aspects of description logics. Possible subjects include:
  • Foundations of description logics, including distinguishing features of description logics with respect to other formalisms, expressive power of description logics, decidability and complexity of reasoning, and novel inference problems and reasoning techniques for solving these problems.
  • Extensions of description logics, including, but not limited to, closed world reasoning, defaults, epistemic reasoning, temporal and spatial reasoning, procedural knowledge, and query languages.
  • Integration of description logics with other formalisms, such as object-oriented representation languages, database query languages, constraint-based programming, logic programming, and rule-based systems.
  • Use of description logics in applications or areas such as natural language, planning, learning, databases, document management, semistructured data, ontology design, ontology languages, ontology engineering, semantic web, and grid computing.
  • Building systems based on description logics, with special emphasis on optimization and implementation techniques.
  • Tools that exploit description Logic reasoning, such as ontology editors, database schema design, query optimization, and data integration tools.

Submission Details

We invite submissions of technical papers as extended abstracts of 8 pages, and submissions of statements of interest of 2 pages. The technical papers will be judged according to their scientific quality, while the statements of interest will be judged according to their scientific relevance. Accepted papers will be included in the workshop proceedings as extended abstract (8 pages), regular papers (12 pages), or as statements of interest (2 pages). The workshop proceedings will be distributed in paper form at the workshop, and will be made available electronically in the CEUR Workshop Proceedings series.

The workshop will take place in the charming town of Brixen-Bressanone, near Bozen-Bolzano in South Tyrol at the heart of the Dolomites - the pink mountains of the Alps. Like Bozen-Bolzano, Brixen-Bressanone has always been a crossroads of various cultures and it is distinguished by its mediaeval Gothic architecture. The mediaeval alleys and the wealth of historical references are an ideal starting point for excursions into the countryside and for practising a whole variety of sports and leisure activities. Leaving directly from the town centre delegates can set off on their bikes or on foot for excursions into the surrounding hills and mountains. Brixen-Bressanone is on the main arterial road between Austria/Germany and Italy and it is easily accessible from everywhere by train, car, bus or plane.
