The 2011 International Workshop on
Web-scale Knowledge Representation, Retrieval, and Reasoning (Web-KR3 2011)

Lyon, France
22 August 2011



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-KR3) 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-KR3 needs to be developed.

Following the successful 2010 version of the workshop under the same title. 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-KR3 in a synergistic setting. The workshop will be co-located with the 2011 IEEE/WIC/ACM International Conferences on Web Intelligence and Intelligent Agent Technology.

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.
  • Web enabled real-time retrieval and reasoning.
  • New forms of inductive and deductive reasoning (e.g. cognitive and nature inspired methods).
  • Spatial and Temporal reasoning methods for the Web.
  • 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-scale ontology and rule interchange and integration.(e.g. via OWL 2, RIF, and RuleML)
  • Dynamics of knowledge updating and forgetting on the Web.
  • Distributed query answering over Web-scale data.
  • Cross-fertilizing Web-KR3 with Distributed AI, Distributed Description Logic, and Distributed Logic Programming.

Invited Talk

Title: Abduction Technology for Web-based Knowledge Representation and Reasoning

Abstract: Abduction is a reasoning from observations to explanations, which is new knowledge related to the old knowledge. It becomes more and more important with the growing popularity of Description Logics-based knowledge representation systems in the Semantic Web. In this talk, we present the emergency of applying abductive reasoning to web-based knowledge representation and reasoning applications. We then propose a general method for abductive reasoning in the Description Logics ALC. The proposed approach has been implemented. We report some initial experiments in which we apply our abductive reasoning method to some realistic ontologies. This evaluation shows that our abductive reasoning is useful and promising. Finally, scalability issues of abductive reasoning are discussed.

Brief Bio:
Dr. Jun Fang is an assistant professor in the school of automation at Northwestern Polytechnical University, China. He is visiting Knowledge Representation & Reasoning in the AI department (Faculty of Science) at the Vrije Universiteit Amsterdam. During his visit, he participates the LarKC project, which aims to develop the Large Knowledge Collider, a platform for very large scale semantic web reasoning. His current work focuses on Semantic Web and ontology reasoning, especially on scalable reasoning and reasoning with inconsistent ontologies.
