Call For Papers

=============== First Call for Papers ===============


Workshop at WWW 2012 – Lyon, France, 16 or 17 April 2012

The purpose of this workshop is to investigate new 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. Semantics can be used to enhance the analysis of usage data. 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 and logs can form valuable resources from which semantic knowledge can be extracted bottom-up.

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 countsʼ. Usage analysis is a key method for the evaluation of a 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. 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.

Data Challenge
In addition to regular papers, USEWOD2012 includes a data challenge. We will release a dataset of usage data (server log files) from Linked Open Data sources. This year's challenge will be even more exiting than the USEWOD2011 challenge, as we add log files from two new linked data sources: and In addition, new logfiles will be provided from the two sources of the USEWOD2011 dataset: Semantic Web Dog Food ( and DBpedia ( Participants are invited to present interesting analyses, applications, alignments, etc. for these datasets, and to submit their findings as a Data Challenge paper. A price will be awarded to the best contribution.

Topics of interest
USEWOD2012 welcomes all research that combines usage data and the web of data, for instance work on:
* 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, personalization and adaptation.
* Usage-based recommendation, personalization and adaptation of semantic web applications.
* Exploiting usage logs for semantic search.
* Data sharing, privacy, and privacy-protecting policies and techniques.

Important dates
* Release of Dataset for the USEWOD2012 Challenge: 15 December 2011
* Paper submission deadline: 15 February 2012
* Workshop and Prize for USEWOD Challenge: 16 or 17 April 2012

The page limit for regular as well as challenge papers is 8 pages, but we also welcome shorter contributions. Papers should be formatted in ACM format ( Visit for submission information.
