ECAI 98 Brighton

The 13th European Conference on Artificial Intelligence, held in Brighton, UK, in August 1998, attracted 456 submissions from 43 different countries, including 138 short papers presenting recent ongoing works by young researchers. The aim of the conference is to cover all aspects of AI, and to bring together basic and applied research. The International Programme Committee selected 158 papers, which are presented in this volume. The proceedings are organized into 16 Belief Revision and Nonmonotonic Reasoning; Case-Based Reasoning and Knowledge-Based Systems; Cognitive Modelling; Computational Linguistics and Ontologies; Constraint-Based Reasoning; Diagnosis; Distributed AI and Multiagent Systems; Knowledge Representation; Logic Programming and Automated Reasoning; Machine Learning and Data Mining; Planning and Scheduling; Reasoning about Actions, Temporal and Spatial Reasoning; Reasoning under Uncertainty (Probabilistic and Fuzzy Set-Based Modelling); Robotics, Vision and Signal Understanding; Search and Meta-Heuristics for AI; and User Interfaces. With an acceptance rate of 34%, ECAI-98, like the previous ECAI conferences, belongs to the stream of high quality AI conferences. The proceedings also contain extended abstracts or papers accompanying the six invited talks.
