In conjunction with the
29th International Conference on Machine Learning (ICML 2012)
Edinburgh, UK, June 30, 2012


The International Workshop on Learning from User-generated Content (LUC)
serves as a forum for theoretical and practical discussions of cutting
edge research on machine learning technologies for multimedia 
information retrieval. Topics covered include all aspects of machine 
learning with a relation to social media and user-generated content, in 
particular, (social) web mining, multimedia information extraction, 
retrieval, and recommendation as well as mobile applications and 
services that make use of machine learning and Web technology. 
Submissions addressing concrete implementations of systems and services 
by both academic institutions and industrial companies are also welcome.


Call for Papers:
----------------
While the amount of user-generated content has been skyrocketing since 
the advent of social media and social networks, intelligent approaches 
to process and make sense of these huge masses of data produced by over 
a billion users are rather rare so far.
Hence, we solicit innovative technical papers with a focus on 
user-generated content and addressing problems in the fields of machine 
learning, multimedia, or information retrieval. Also contributions that 
combine two or more of these fields are highly welcome.
We invite authors to submit *** regular technical papers of up to 8 
pages *** as well as *** short position or demo papers of 2-4 pages ***.
Regardless of their category, submissions must follow the ACM author 
guidelines. Paper submissions must be original and not submitted to or
accepted by any other conference or journal. All submissions to this 
workshop will be peer-reviewed by at least three Program Committee 
members. The review process will be double-blind.

-------------------
- Social Media and Network Analysis
- Social Media Mining
- Influential User Detection and Analysis
