Following the success of last MultiClust workshops at KDD 2010 and ECML PKDD 2011, we invite submissions to
the 3rd MultiClust workshop on discovering, summarizing and using multiple clusterings to be held in
conjunction with SDM 2012.

Traditionally, clustering has focused on discovering a single summary of the data. In today's
applications, however, data is collected for multiple analysis tasks. Several features or
measurements provide complex and high dimensional information. In such data, one typically observes
several valid groupings, i.e. each data object fits in different roles. In contrast to traditional
clustering these alternative clusterings describe multiple aspects that characterize the data in
different ways.

The topic of multiple clustering solutions by itself shows multiple research aspects: multiple
alternative solutions vs. a single consensus that integrates different views; given views in
multi-source clustering vs. detection of novel views by feature selection and space transformation
techniques; a virtually unlimited number of alternative solutions vs. a non-redundant output
restricted to a small number of disparate clusterings. Further aspects are induced by data
representations ranging from traditional continuous valued vector spaces to complex models using
graphs, sequences, streams, etc.

The topic of multiple clustering solutions has opened novel challenges in a number of research fields.
Examples from the machine learning and knowledge discovery communities include frequent itemset
mining, ensemble mining, constraint-based mining, theory on summarization of results, or consensus
mining to name only a few. We observe fruitful input from these established related areas. Overall, this
cross-disciplinary research endeavor has recently received significant attention from multiple
communities. In this workshop, we plan to bring together the researchers from the above research areas to
discuss issues in multiple clustering discovery.

TOPICS OF INTEREST
---------------------------
The panel discussions at the last MultiClust workshops and a recent tutorial on discovering multiple
clustering solutions document the research interest on this exciting topic. A non-exhaustive list of
topics of interest is given below:

* Discovering multiple clustering solutions
o Alternative clusters / disparate clusters / orthogonal clusters
o Multi-view clustering / subspace clustering / co-clustering
o Multi-source clustering / clustering in parallel universes / multi-represented clustering
o Feature selection and space transformation techniques
o Constraint-based mining for the detection of alternatives
o Non-redundant view detection and non-redundant cluster detection
o Model selection problem: how many clusterings / how many clusters
o Iterative vs. simultaneous processing of multiple views
o Scalability to large and high dimensional databases
o Tackling complex databases (e.g. graphs, sequences, or streams)
* Summarizing multiple clustering solutions
o Ensemble techniques
o Meta clustering
o Consensus mining
o Summarization and compression theory
* Using and evaluating multiple clustering solutions
o Classification based on multiple clusterings
o Evaluation metrics / evaluation methodology for multiple clustering solutions
o Visualization and exploration of multiple clusterings
* Related research fields
o Frequent itemset mining
o Subgroup mining
o Subspace learning
o Multilabel classification
o Relational data mining
o Transfer mining
* Applications of multiple clustering solutions
o Bioinformatics: gene expression analysis / proteomics / ...
o Sensor network analysis
o Social network analysis
o Health surveillance
o Customer segmentation
o ... and many more ...

We encourage submissions describing innovative work in other, related, fields that address the issue of
multiplicity in data mining.

SUBMISSION GUIDELINES
---------------------------
We invite submission of unpublished original research papers that are not under review elsewhere. All
papers will be peer reviewed. Papers may be up to 8 pages long. We also invite vision papers and
descriptions of work-in-progress or case studies on benchmark data as short paper submissions of up to 4
pages. If accepted, at least one of the authors must attend the workshop to present the work.

Contributions should be submitted in pdf format using the workshop’s EasyChair submission site at
http://www.easychair.org/conferences/?conf=multiclust2012 The submitted papers must be written
in English and formatted according to the SDM 2012 submission guidelines. We would like to encourage you
to prepare your paper in LaTeX2e. Papers should be formatted using the SIAM SODA macro, which is available
through the SIAM website. You can access it at http://www.siam.org/proceedings/macros.php. The
filename is soda2e.all. Make sure you use the macros for SODA and Data Mining Proceedings; papers
prepared using other proceedings macros will not be accepted.

If you are considering submitting to the workshop and have questions regarding the workshop scope or need
further information, please do not hesitate to contact the PC chairs.

PROCEEDINGS
---------------------------
We will edit on-line proceedings of all accepted papers so that the results are widely accessible.
Proceedings will be published through the CEUR Workshop Proceedings (CEUR-WS.org) publication
service in time for the workshop. If there is sufficient interest and quality of papers, we will also
consider a post-workshop publication (e.g., as a special issue in a journal).
