GermEval 2019 Task 1 - Shared Task on hierarchical classification of German Blurbs

First Call for Participation

This is the call to participate in the shared task on hierarchical classification on blurbs at the GermEval 2019. We invite everyone interested to participate in this shared task. The shared task can be found under this webpage: https://competitions.codalab.org/competitions/21226.

Introduction

Hierarchical multi-label classification (HMC) of blurbs is the task of classifying multiple labels for a short descriptive text, where each label is part of an underlying hierarchy of categories. The increasing amount of available digital documents and the need for more and finer-grained categories calls for new, more robust and sophisticated text classification methods. Large datasets often incorporate a hierarchy for, which can be used to categorize information of documents on different levels of specificity. The traditional multi-class text classification approaches are thoroughly researched, however, with the increase of available data and the necessity of more specific hierarchies and since traditional approaches fail to generalize adequately, the need for more robust and sophisticated classification methods increases.

With this task we aim to foster research within this context. This task is focusing on classifying German books into their respective hierarchically structured writing genres using short advertisement texts (blurbs) and further meta information such as author, page number, release date, etc.

Tasks

This shared task consists of two subtask, described below. You can participate in one of them, or in both.

Subtask A: The task is to classify German books into one or multiple most general writing genres. Therfore, it can be considered a multi-label classification task. In total, there are 8 classes that can be assigned to a book: Literatur & Unterhaltung, Ratgeber, Kinderbuch & Jugendbuch, Sachbuch, Ganzheitliches Bewusstsein, Glaube & Ethik, Künste, Architektur & Garten.

SubTask B: The second task targets hierarchical multi-label classification into multiple writing genres. In addition to the very general writing genres, additional genres of different specificity can be assigned to a book. In total, there are 343 different classes that are hierarchically structured on up to 4 levels.

Data

The dataset for this task consists in total of 20,784 examples. Sample data is already available to get familiar with the data structure of this task. Training data is going to be released in February and can be downloaded after registering for the shared tasks. The evaluation of the task will take place in July 2019. More information can be found on the GermEval-2019 website at: https://competitions.codalab.org/competitions/21226
