MOTIVATION

Recommendation techniques generally rely on data referring to three kinds of objects: users, items and their relations. The widespread success of Semantic Web techniques, creating a Web of interoperable and machine readable data, offers novel strategies to represent data that might improve the current state of the art of recommender systems, in order to move towards a new generation of recommender systems which fully understand the items they deal with.

Indeed, more and more semantic data are published following the Linked Data principles, that enable to set up links between objects in different data sources, by connecting information in a single global data space - the Web of Data. Today, Web of Data includes different types of knowledge represented in a homogeneous form - sedimentary one (encyclopedic, cultural, linguistic, common-sense and real-time one (news, data streams. This data might be useful to interlink diverse information about users, items, and their relations and implement reasoning mechanisms that can support and improve the recommendation process.

The challenge is to investigate whether and how this large amount of wide-coverage and linked semantic knowledge can significantly improve complex search and filtering tasks that cannot be solved merely through a straightforward matching of queries (or user profiles) and items. Such tasks involve finding information from large document collections, categorizing and understanding that information, and producing some output, such as an actionable decision. Examples of such tasks include understanding a health problem in order to make a medical decision, or simply deciding which laptop to buy. Recommender systems support users exactly in those complex tasks.

TOPICS

Topics of interest include (but are not limited to):

• Recommendation approaches exploiting Big Data and Semantic technologies
• Linked Data for Recommender Systems
• Ontology-based recommendation algorithms
• Reasoning with Big Data
• Discovery of relevant Linked Data sources for recommendation algorithms
• Linking, aggregating, intertwining and mining Linked Data for recommender systems
• Linked Data in new Recommender Systems architectures
• Semantic technologies for Cross-lingual and cross-domain recommender systems
• Semantic technologies for improving transparency and explanations
• Big datasets for the evaluation
• Evaluation methodologies for real time personalization in big datasets
• Semantic technologies for improving novelty, diversity and serendipity

SUBMISSION

We welcome work at all stages of development: papers can describe applied systems, empirical results or theoretically grounded positions.

Accepted papers will be published as CEUR workshop proceedings (http://ceur-ws.org). Based on the quality of accepted papers we are planning to schedule a special issue of a top-level journal in 2013.

• Full papers (5-6 pages)
• Short papers (2-3 pages)
• Demos (1-2 pages for description)

Papers should be formatted according to the general RecSys2013 submission guidelines. Accepted format is PDF.
