LSHC3: ECML/PKDD - PASCAL Discovery Challenge Workshop on Large-Scale
Hierarchical Classification
September 28, 2012, Bristol, UK
http://lshtc.iit.demokritos.gr/LSHC3_workshop

SCOPE
Hierarchies are becoming ever more popular for the organization of
documents, particularly on the Web (e.g. Web directories). Along with
their widespread use comes the need for automated classification of
new documents to the categories in the hierarchy. Research on large-
scale classification so far has focused on large numbers of documents
and/or large numbers of features, with a limited number of categories.
However, this is not the case in hierarchical category systems, such
as DMOZ or Wikipedia. Approaching this problem, researchers have
either extended existing large-scale classifiers, or have developed
new models and methods.
LSHC3 is the third in the series of workshops on large-scale
hierarchical classification. The workshop aims at bringing together
researchers and practitioners of large-scale category systems and thus
welcomes theoretical studies, as well as studies reporting the
development of large-scale categorizers or components of such
categorizers. In particular, some of the issues that we expect to
cover in the workshop are:
* Learning to classify against many categories
* Data sparseness in the presence of large datasets
* Use of the statistical dependence of hierarchically organized
classes
* The role of shrinkage methods in large hierarchies
* Ensemble methods for hierarchical classification
* Extending existing large-scale classifiers to hierarchies
* Multi-task and transfer learning within and across large hierarchies
* Unsupervised or semi-supervised extension of hierarchies
* Computational issues in large-scale categorization
* Challenging hierarchical classification tasks and datasets

IMPORTANT DATES
* Paper submission - July 27
* Acceptance notification - August 10
* Camera-ready paper - August 24

SUBMISSIONS
We encourage submissions on all aspects of large-scale categorization,
from purely theoretical work to practical developments of large-scale
categorizers. Submissions must be written in English, following the
LNCS guidelines and must not exceed 12 pages including references and
figures. The Easychair electronic submission system will be used for
the papers. Please, refer to the workshop page for details about the
submission format and process.
