The Spanish Information Retrieval Society (SERI), organizer of this event, has as main goal to support IR in Spain. This conference aims to continue with the work developed on its previous editions and to provide an international forum where researchers from both academia and industry can meet, exchange experiences and present innovative works. CERI welcomes contributions from a wide range of knowledge areas. Specifically, we encourage the participation of not only researchers and professionals from the Computer Science field, but also researchers with background and experience on Information Sciences, Linguistics, or any other related area to IR.

All scientists interested in IR related fields are welcome to participate. We encourage national and international researchers from both academia and industry to submit original papers, written either in Spanish or English, related to any aspect of IR including, but not limited to the following:

• IR models
• Performance, scalability, architectures and efficiency
• Data structures on IR
• Web IR
• IR Quality Evaluation
• User aspects: interaction, user studies and interfaces
• Filtering and recommendation systems
• Structured retrieval (XML, etc.)
• Semantic search
• Digital libraries
• IR in social networks
• Opinion mining
• Vandalism detection in the Web, in Wikipedia and opinion spam
• Detection of pedophilia, stalking and bullying
• Multimedia retrieval
• Text mining (classification and clustering)
• Natural Language Processing in IR
• Passage Retrieval and Question Answering
• Multilingual and cross-language IR
• IR in specific domains (biomedical, patents, law, etc.)
• Geographical IR
• Collaborative IR

All accepted works will be published in the ACM International Conference Proceeding Series (ICPS), indexed by the ACM Digital Library (ISBN 978-1-4503-4141-7).

From a selection of the best papers, an special issue of the International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems (IJUFKS) will be edited.
