Web site Classification Track


The purpose of this track is to evaluate methods of Web site topic classification.

For this track the standard procedure is used.

Test Collection

The source dataset consists of Narod.ru and DMOZ collections. The latter is used as a training set.

Task Description for Participating Systems

Each participant is granted access to the training set, DMOZ collection, a set of web sites (not separate web pages!) from the Narod.ru collection. The task is to assign topics from training set to each web to each web site. Valid number of topics per site is from 0 to 5. Topics should be returned as an ordered list for each web site.

The training set is based on a subset of the Russian-language categories from the DMOZ catalog.

It's suggested that all the sites from the narod.ru collection are classified by participants, i.e. not only narod.*, but also narod_training.* archives.

The training set contains also several sites from the narod.ru domain. These sites will be excluded from the results during evaluation.
