In recent years, we have seen a surge of interest that deals with the discovery and automatic creation of complex, multirelational knowledge structures. For example, the natural language community tries to acquire word semantics from natural language texts, database researchers tackle the problem of schema induction, and people building intelligent information agents research the learning of complex structures from semi-structured input (HTML, XML). All the while, efforts in the machine learning community pursue the induction of more concise and more expressive knowledge structures (e.g., relational learning) in general. For the workshop we intend to gather a diverse range of participants interested in the machine learning of ontologies. In particular, we are also interested in the maintenance (revision, incrementality) and integration (from various sources) aspects of learning ontologies. Topics of interest include, e.g.: Text mining for building ontologies Learning from machine-readable dictionaries Lexical acquisition Learning selectional restrictions Semi-automatic extending of ontologies (WordNet) Multi-relational learning / Inductive Logic Programming A-Box Mining Learning ontologies with inferences (e.g. using description logics) Learning ontologies from the Web (from DTDs, XML, RDF) Cooperative learning of ontologies Learning translation rules between ontologies Reverse Engineering relational schemas to ontologies Besides of the common digital presentations, we intend that participants give live system demonstrations. An invited talk "Learning to translate between ontologies" will be given by Alon Halevy, University of Washington. Important Dates Deadline for paper submission 21 February 2001 Notification of acceptance 21 March 2001 Deadline final contributions 30 April 2001 All accepted papers will be published in the IJCAI-2001 workshop proceedings. Submission Information We invite contributions that advance the state-of-the-art in topics related to the purpose of the workshop. Persons interested in participating should submit either a technical paper (less than 6000 words) or a position paper (less than 1500 words) addressing new research issues. In addition, we solicit proposals for panel discussions and break-out groups that work towards visions for ontology learning.
