The conference on Ontologies, DataBases, and Applications of Semantics for Large Scale Information Systems (ODBASE'14) provides a forum on the use of ontologies and data semantics in novel applications. Of particular relevance to ODBASE 2014 are papers that bridge traditional boundaries between disciplines such as databases, social networks, mobile systems, artificial intelligence, information retrieval, and computational linguistics. We also encourage the submission of research and practical experience papers concerning scale issues in ontology management, information integration, and information extraction, as well as papers that examine the information needs of various applications.
