16 May 2013: We have just release the dataset for the on-site hacking challenge, which is a significantly smaller subset of our regular challenge data. You can download it freely, but please note that it is only meant to be used for participation in the USEWOD on-site hacking challenge! 04 May 2013: Just a little heads up that we are planning an on-site hacking challenge with a subset of our challenge data during the workshop. Watch this space for the release of the data subset! Also, the deadline for the 2-page late research abstracts is up very soon, so if you want to join the discussion at the workshop with a short talk, let us know what you are working on! 21 February 2013: Due to the delayed release of the USEWOD2013 challenge dataset, we have pushed back the submission deadline by two weeks to March 22nd! 17 February 2013: We have just released the new challenge data for USEWOD2013, including more DBpedia logs, more SWDF logs and two additional sources of SPARQL queries from the bio-medial domain. Head over to the Challenge page! 07 December 2012: We are very happy to announce that USEWOD has been accepted as a workshop for this year's ESWC in Montpellier!

Workshop Overview and Goals

The purpose of the USEWOD workshop series is to investigate developments concerning the synergy between semantics and semantic-web technology on the one hand, and the analysis and mining of usage data on the other hand. As the first and second USEWOD workshops at WWW 2011 and 2012 have shown, these two fields complement each other well. First, semantics can be used to enhance the analysis of usage data. Second, usage data analysis can enhance semantic resources as well as Semantic Web applications; traces of users can be used to evaluate, adapt or personalize Semantic Web applications.

The emerging Web of Data demands a re-evaluation of existing evaluation techniques: the Linked Data community is recognizing that it needs to move beyond triple counts because real value of Web data needs to be measured by real use. Usage analysis is a key method for the evaluation of datasets and applications. New ways of accessing information enabled by the Web of Data requires the development or adaptation of algorithms, methods, and techniques to analyze and interpret the usage of Web data instead of Web pages, a research endeavour that can profit from what has been learned in more than a decade of Web usage mining. The results can provide fine-grained insights into how semantic datasets and applications are being accessed and used by both humans and machines – insights that are needed for optimising the design and ultimately ensuring the success of semantic resources.

The primary goals of this workshop are to foster the emerging community of researchers from various fields sharing an interest in usage mining and semantics, to evaluate the developments of the past year, and to further develop a roadmap for future research in this direction. We aim to build on the success and direct and indirect effects of the two prior USEWOD workshops at WWW 2011 and 2012. In particular, we can build on the success of the USEWOD Data Challenges, which provided data that was analysed in a variety of ways in publications at USEWOD and elsewhere. We will therefore also propose a new challenge.

Topics of Interest (not limited to)

We welcome work that shows how the research areas combine: how semantic resources and techniques can be used to strengthen usage data analysis and, vice versa, how usage data can enhance semantic tools and applications. Within these boundaries, we keep the scope broad. We welcome contributions using any form of semantic information, from formal ontologies to linked data and folksonomies. All records of user actions are considered usage logs; we do not limit ourselves to any format or method of collection of usage information. This ranges from traditional content-consumption logs to various forms of content-production logs, i.e. navigation, application-related transactions, queries, tagging, editing, and similar activities. We welcome both papers using the USEWOD data set (competing in the challenge) and papers on other relevant topics. Topics of interest include, but are not limited to:

• Analysis and mining of usage logs of semantic resources and applications.
• Inferring semantic information from usage logs.
• Methods and tools for semantic analysis of usage logs.
• Representing and enriching usage logs with semantic information.
• Usage-based evaluation methods and frameworks; gold standards for evaluation of web applications.
• Specifics and semantics of logs for content-consumption and content-creation.
• Using semantics for recommendation, personalisation and adaptation.
• Usage-based recommendation, personalisation and adaptation of semantic web applications.
• Exploiting usage logs for semantic search.
• Data sharing, privacy, and privacy-protecting policies and techniques.

Contributions

We invite regular paper submissions, as well as challenge papers. Papers must consist of original, unpublished research and must not be under review by another conference, journal, or workshop. Accepted papers will be published online via arXiv.org. Authors of accepted submissions will be invited to present their work at the workshop, and at least one author of each paper must register for the workshop. To register, please visit the ESWC2013 website.

We also invite late 2-page research abstracts, which will not be published as part of the USEWOD 2013 workshop proceedings, but if accepted will be invited to be presented as a 15 minute talk at the day of the workshop.

Format requirements for the submission of papers are (details may change!):

• Regular Papers: max. 8 pages
• Data Challenge Papers: max. 8 pages
• (however, we also welcome shorter papers)
• Late Research Abstracts: max. 2 pages (not part of workshop proceedings)

All accepted papers will be included in the online workshop proceedings. All papers must be prepared in ACM format.

Metadata about all papers and talks, including title, abstract, authors and author affiliations, will also be made available publicly at http://data.semanticweb.org.

To submit a paper or abstract, please log on to the USEWOD2013 page on EasyChair.

USEWOD 2013 Data Challenge

As in previous years, there will is a new USEWOD data challenge, for which participants are invited to present interesting analyses, applications, alignments, etc., and to submit their findings as a Data Challenge paper. The best Data Challenge paper will receive a prize sponsored by Datalysator Web Data Consulting. More details can be found on the Challenge page.
