Breakout sessions

Group 1: Mapping (Renee Miller)
     <Slides>
Technical challenges associated with integration at the conceptual level.
Topics include: Data models; uncertainty (in data and mappings); use of constraints in integration; mapping formalisms- expressiveness (declarative, procedural, and trigger-based schemes); schema evolution; directionality/trust (unidirectional vs. bidirectional or invertible); interactions with constraints; "combining modalities" (mappings over text; unstructured data; semi-structured data; structured data); using mappings in data transformation, schema evolution, data integration (answering queries using views), data exchange, querying, search, and ranking in integrated systems; manipulating/managing mappings (mapping composition/inversion, integrated view maintenance-notification, subscription, mapping maintenance and adaptation).

Group 2: Matching (David Maier)
     <Slides>
Technical challenges associated with integration at the instance level.
Topics include: Instance matching; interactions of instance with schema matching; normalization and ontologies; uncertainty in matching and data; reasoning with uncertainty; probabilistic joins; using contraints to clean and integrate data; data quality; "hands off" integration and automated matching; keyword-based search.

Group 3: Integration Architectures (H.V. Jagadish)
     <Slides>
Enabling integration.
"Modes" of integration (views, manual copy-paste, "transclusion", mash-ups); "end-to-end" integration (assemblies of II systems); how communities establish the will to collaborate and a common understanding (schema, ontology) of the sources they wish to integrate; designing/preparing sources for integration; important "non-technical" issues: social, legal, economic, etc.

Group 4: Information Integration in Context (Peter Buneman)
     <Slides>
This session will look at related technical issues and the context in which we use II.
Data quality (or selecting the "best" source based on availability/performance rather that quality); source discovery; source enhancement; quality assessment and provenance; conveying annotation and provenance; integrated view maintenance; data cleaning; security and privacy.
