The 2012 International Workshop on
Web-scale Knowledge Representation, Retrieval, and Reasoning (Web-KR 2012)

co-located with the 21st ACM International Conference on Information and Knowledge Management (CIKM 2012)
Sheraton, Maui Hawaii

29 October 2012




The World Wide Web has become the carrier for the largest human knowledge repository in history. As its knowledge bases are growing towards a practically ‘infinite’ volume, Web-scale Knowledge Representation, Retrieval, and Reasoning (Web-KR) is becoming a real issue and an urgent task. Although the Web community has developed a number of knowledge representation languages and reasoning methods, when the volume goes Web-scale, existing approaches meet many challenging problems, such as scalability, inconsistency, uncertainty and dynamics. Hence, a unified approach to Web-KR needs to be developed.

Following the successful 2010 and 2011 versions of the workshop under the same title in Toronto, Canada and Lyon, France. This workshop aims to bringing together researchers from Web research, Artificial Intelligence (AI), high performance computing, cognitive science, knowledge management, and machine learning to discuss all issues of Web-KR in a synergistic setting. The workshop will be co-located with the 2012 ACM International Conference on Information and Knowledge Management (CIKM 2012) in Maui Hawaii, the United States.

News!!! : Web-scale Knowledge Representation, Retrieval, and Reasoning (Web-KR) 2012 workshop will be co-located with the City Data Management 2012 Workshop (CDMW 2012). The program can be accessed HERE. See you in Hawaii to share the recent progress on Knowledge Representation, Retrieval and Reasoning as well as City Data Management in the Web age!

Topics of Interest

Research contributions should be related but are not limited to one or more of the following topics:

  • Expressivity of Web-scale common sense knowledge.
  • Parallelization and distribution techniques for Web-scale knowledge retrieval and reasoning.
  • Inconsistency, uncertainty, and relevancy of Web-scale reasoning.
  • Granularity of knowledge representation, retrieval and reasoning.
  • Web enabled real-time retrieval and reasoning.
  • New forms of inductive and deductive reasoning (e.g. cognitive and nature inspired methods).
  • Ontology and rule interchange and integration.(e.g. via OWL 2, RIF, and RuleML)
