Call for Participation


Dear All,

this is the first call to participate in the shared task on identification of 
offensive language GermEval 2018. We invite everyone from academia and industry 
to participate in the shared task on Identification of Offensive German 


Offensive Language is commonly defined as hurtful, derogatory or obscene 
comments made by one person to another person. This type of language can 
increasingly be found on the web. As a consequence many operators of social 
media websites no longer manage to manually monitor user posts. Therefore, 
there is a pressing demand for methods to automatically identify suspicious 

This pilot shared task is to initiate and foster research on the identification 
of offensive content in German language microposts. Offensive comments are to 
be detected from a set of German tweets. We focus on Twitter since tweets can 
be regarded as a prototypical type of micropost.

The workshop discussing this year's edition of this shared task is planned to 
be held in conjunction with the Conference on Natural Language Processing 
(KONVENS ) in Vienna in September 2018.


Some sample data (i.e. 100 manually labeled tweets) and an evaluation script 
are now ready and available on our website (URL see above). The training data, 
which are going to be released in April, can be downloaded after registering 
with the organizing committee. The task evaluations will take place in July 
2018. For more details please consult the GermEval-2018 website.


We offer the two tasks described below. Participants in this year's shared task 
can choose to participate in one or both of them.

Task I - Binary classification

The task is to decide whether a tweet includes some form of offensive language 
or or not.

Task II - Fine-grained classification

In addition to detecting abusive language tweets, we distinguish between three 

PROFANITY: usage of profane words, however, the tweet clearly does not want to 
insult anyone.

INSULT: unlike PROFANITY the tweet clearly wants to offend someone.

ABUSE: unlike INSULT, the tweet does not just insult a person but represents 
the stronger form of abusive language
