Call for Papers LSHC2: Joint ECML/PKDD - PASCAL Workshop on Large-Scale Hierarchical Classification September 5, 2011 (as part of the ECML/PKDD 2011 conference) http://lshtc.iit.demokritos.gr/LSHC2_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. LSHC2 is the second 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 * Computational issues in large-scale categorization * Challenging hierarchical classification tasks and datasets ********************************************************* IMPORTANT DATES * Paper submission - June 20 * Acceptance notification - July 8 * Final paper - July 21 ********************************************************* 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. ********************************************************* ORGANISERS George Paliouras, NCSR "Demokritos", Athens, Greece Eric Gaussier, UJF/LIG, Grenoble, France Aris Kosmopoulos, NCSR "Demokritos" and AUEB, Athens, Greece Ion Androutsopoulos, AUEB, Athens, Greec Thierry Artières, LIP6, Paris, France Patrick Gallinari, LIP6, Paris, France _______________________________________________ Elsnet-list mailing list Elsnet-list_(at)_mailman.let.uu.nl http://mailman.elsnet.org/mailman/listinfo/elsnet-list
