This workshop aims to gather innovative approaches for knowledge extraction and consolidation from unstructured social media, in particular from degraded user-generated content (text, images, video) such as tweets, blog posts, forums and user-generated visual media. KECSM will gather novel works from the fields of (a) data analysis and knowledge extraction, and (b) data enrichment, interlinking and consolidation. It will equally consider the application perspective, such as the innovative use of extracted knowledge to navigate, explore or visualise previously unstructured and disparate Web content. The workshop will provide a highly interactive forum for researchers in the fields of semantic and social Web, text mining and NLP, multimedia data analysis, clustering and integration, and ontology and data mapping. There will also be a keynote speech by Seth Grimes on perspectives from an industry viewpoint.

The workshop will take place in the afternoon of Monday 12 November, 2012.
