Workshop Goals
</x-tad-bigger>The workshop aims to bring together researchers in relevant areas of artificial intelligence (machine learning, data mining, knowledge representation, ontologies), information systems (information integration, databases, semantic Web), distributed computing, and selected application areas (e.g., bioinformatics, security informatics, environmental informatics) to address several questions that arise in the process of knowledge acquisition from distributed, autonomous, semantically heterogeneous data and knowledge sources.

<x-tad-bigger>Topics of Interest
</x-tad-bigger><x-tad-bigger>Topics of interest include, but are not restricted to:
</x-tad-bigger>
</x-tad-bigger><x-tad-bigger>• </x-tad-bigger><x-tad-bigger>Knowledge discovery from distributed data (assuming different types of data fragmentation, e.g., horizontal or vertical data fragmentation; different hypothesis classes, e.g., naïve Bayes, decision tree; different performance criteria, e.g., accuracy versus complexity versus reliability of the model generated, etc.).
</x-tad-bigger><x-tad-bigger>• </x-tad-bigger><x-tad-bigger>Making semantically heterogeneous data sources self-describing (e.g., by explicitly associating ontologies with data sources and mappings between them) in order to help collaborative science .
</x-tad-bigger><x-tad-bigger>• </x-tad-bigger><x-tad-bigger>Representation, manipulation, and reasoning with ontologies and mappings between ontologies.
</x-tad-bigger><x-tad-bigger>• </x-tad-bigger><x-tad-bigger>Learning ontologies from data (e.g., attribute value taxonomies).
</x-tad-bigger><x-tad-bigger>• </x-tad-bigger><x-tad-bigger>Learning mappings between semantically heterogeneous data source schemas and between their associated ontologies.
</x-tad-bigger><x-tad-bigger>• </x-tad-bigger><x-tad-bigger>Knowledge discovery in the presence of ontologies (e.g., attribute value taxonomies) and partially specified data (data described at different levels of abstraction within an ontology)?
</x-tad-bigger><x-tad-bigger>• </x-tad-bigger><x-tad-bigger>Online query relaxation when an initial query posed to the data sources fails (i.e., returns no tuples), or equivalently, query-driven mining of the individual sources that will result in knowledge that can be used for query relaxation.
