HASOC-Offensive Language Identification- DravidianCodeMix FIRE 2020


There is an increasing demand for offensive language detection on social media texts which are largely code-mixed. Code-mixing is a prevalent phenomenon in a multilingual community and the code-mixed texts are sometimes written in non-native scripts. Systems trained on monolingual data fail on code-mixed data due to the complexity of code-switching at different linguistic levels in the text. This shared task presents a new gold standard corpus for offensive language detection of code-mixed text in Dravidian languages (Malayalam-English and Tamil-English). 

The goal of this task is to identify offenslve language of the code-mixed dataset of comments/posts in Dravidian Languages (Malayalam-English and Tamil-English) collected from social media. The comment/post may contain more than one sentence but the average sentence length of the corpora is 1. Each comment/post is annotated with offensive language label at the comment/post level. This dataset also has class imbalance problems depicting real-world scenarios. 

The participants will be provided development, training and test dataset.


This is a message-level label classification task. Given a YouTube comment in Code-mixed Malayalam, systems have to classify it into offensive or not-offensive. 



This is a message-level label classification task. Given a tweet or Youtube comments in Tanglish and Manglish (Tamil and Malayalam using written using Roman Characters), systems have to classify it into offensive or not-offensive.

As far as we know, this is the first shared task on Offensive language in Dravidian Code-Mixed text.
