Very large knowledge repositories (LKR) are being created, published and exploited in a wide range of fields, including Bioinformatics, Biomedicine, Geography, e-Government, and many others. Some well known examples of LKRs include the Wikipedia, large scale Bioinformatics databases such as those published by the EBI or the NIH, and government data repositories such as data.gov. These repositories are publicly available and can be used openly. Their exploitation offers many possibilities for improving current information systems, and opens new challenges and research opportunities to the information processing and databases areas.

The main goal of this workshop is to bring together researchers that are working on the creation of new LKRs on any domain, or on their exploitation for specific information processing tasks such as data analysis, text mining, natural language processing and visualization, as well as for knowledge engineering issues, like knowledge acquisition, validation and personalization.

Research, demo and position papers showing the benefits that exploiting LKRs can bring to the information processing area will be especially welcome to this workshop.

Workshop Topics

The main topics that can be considered relevant to the workshop include, but are not limited to:

• LKRs as high-quality sources of information.
• LKRs characterization and applications.
• LKRs creation from document collections and corpora.
• Knowledge extraction from LKRs.
• Analysis and mining of LKRs.
• Natural language processing tasks and applications of LKRs: Named entity recognition, word sense disambiguation, question answering and answer validation.
• Temporal issues in LKRs.
• Acquisition, validation and management of data and knowledge.
• Knowledge integration issues in LKRs.
• Automatic construction of ontologies, thesauri and corpora from LKR.
• Semantic annotation.
• Semantic search.
  
• LKRs and the Semantic Web.
• LKRs and the Web of Linked Data.
• Social graphs as LKRs.
• Visualization techniques for LKRs.
• Emerging applications of LKRs.
