LSHC3: ECML/PKDD - PASCAL Discovery Challenge Workshop
on Large-Scale Hierarchical Classification

September 28, 2012, Bristol, UK

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.
