In today's knowledge-driven society, effective access to and use of information is a key enabler for progress. Modern technologies not only are themselves knowledge intensive, but also they produce enormous amounts of new information that we must process and aggregate. These technologies require knowledge capture, which involves the extraction of useful knowledge from vast and diverse online sources as well as its acquisition directly from human experts. Driven by the demands for knowledge-based applications and the unprecedented availability of information on the Web, the study of knowledge capture has a renewed importance.

Researchers who work in the area of knowledge capture traditionally participate in several distinct research communities, including knowledge engineering, machine learning, natural language processing, human–computer interaction, artificial intelligence, and the Semantic Web. K-CAP 2011 will provide a forum that brings together members of disparate research communities who are interested in efficiently capturing knowledge from a variety of sources and in creating representations that can be useful for automated reasoning, analysis, and other forms of machine processing.

We solicit high-quality research papers for publication and presentation at our conference. Our aim is to promote multi-disciplinary research that could lead to a new generation of tools and methodologies for knowledge capture. K-CAP 2011 follows on the success of five previous conferences in 2009 (California, USA), 2007 (Whistler, Canada), in 2005 (Banff, Canada), in 2003 (Florida, USA), and 2001 (Victoria, Canada), and of the series of Knowledge Acquisition Workshops (KAW), the first of which took place in the same location (Banff, Canada) in 1986. K-CAP 2011 is particularly important in the history of our discipline, as it coincides with the 25th anniversary of the first Knowledge Acquisition Workshop at the Banff Centre.

The Sixth International Conference on Knowledge Capture, K-CAP 2011 will feature Invited Talks, Technical Papers, Workshops, Posters and Demos on a range of topics including:

* Knowledge acquisition tools
* AKnowledge authoring tools
* Knowledge extraction systems
* Knowledge management environments
* Knowledge capture for the Semantic Web and the Web of Linked Data
* Collaborative and social approaches to knowledge management and acquisition
* Learning apprentices
* Mixed-initiative planning and decision-support tools
* Acquisition of problem-solving knowledge
* Knowledge-based markup techniques
* Advice taking systems
* Knowledge engineering and modelling methodologies

There will be also a special session in the conference on "25 years of Knowledge Acquisition Research", in which presented papers and invited talks will review advances in the past 25 years in all the aforementioned areas.
