Second Call for Papers Deadline: May 1, 2006 AAAI Fall Symposium Semantic Web for Collaborative Knowledge Acquisition (SWeCKa 2006) October 12-15, 2006 Arlington, VA Recent advances in computing, communications together with the rapid proliferation of information sources and services present unprecedented opportunities in integrative and collaborative analysis and interpretation of distributed, autonomous (and hence, inevitably semantically heterogeneous) data and knowledge sources and services in virtually every area of human activity. The symposium aims to bring together researchers in relevant areas of artificial intelligence, databases, knowledge bases, machine learning, information integration, ontologies, semantic web, web services, and relevant application areas (e.g., bioinformatics, environmental informatics, enterprise informatics e-science, e-government, medical informatics, security informatics, social informatics, among others.) to share recent advances in the state of the art in semantic web technologies for such applications. Topics of interest include, but are not limited to: * Cyber-infrastructure and semantic web technologies for collaborative knowledge acquisition * Modeling semantically heterogeneous data sources and services * Collaboratively developing and sharing of ontologies and inter-ontology mappings * Discovering and resolving inconsistencies within and among ontologies * Representing and reasoning with ontologies and mappings between ontologies * Discovering mappings between data source schemas and between ontologies * Querying distributed, semantically heterogeneous information sources * Acquiring knowledge from distributed, autonomous, semantically heterogeneous information sources * Acquiring knowledge from partially specified data * Exploiting distributed knowledge and data in dynamic data-driven applications * Discovering and composing semantically heterogeneous services * Modeling, tracking and using information provenance * Modeling and reasoning about trust of information sources and services * Extracting knowledge and facts from distributed text and multimedia data * Preserving privacy, selective information and knowledge sharing * Case studies, Software Tools, and Prototypes The symposium will include a series of half-day sessions, each addressing a challenge area. Sessions will include invited talks providing overviews of key topics, short presentations based on contributed papers, a poster session for work in progress, breakout sessions focusing on specific research challenges and emerging research directions, a panel discussion and a wrap-up session. Submissions Potential participants are invited to submit full papers (up to 8 pages in length), poster summaries or extended abstracts (1-2 pages in length) by May 1, 2006. Submissions should be in the AAAI camera-ready format (postcript or pdf files) and should be sent electronically to aaai06-SWeCKa@cs.iastate.edu. Each submission will be reviewed by at least two program committee members. Authors of accepted papers and abstracts will be notified by May 22, 2006. Extended versions of selected papers may be published in a special issue of a journal or an edited book. Partial travel support for graduate and postdoctoral students may be available.
