Call For Papers

Multilingual Shallow Discourse Parsing

This is the 2nd edition of the CoNLL Shared Task on Shallow Discourse Parsing, following the first edition in 2015. A participant system is given a piece of newswire text as input and returns discourse relations in the form of a discourse connective (explicit or implicit) taking two arguments (which can be clauses, sentences, or multi-sentence segments). Specifically, the participant system needs to

locate both explicit (e.g., "because", "however") discourse connectives in the text
identify the spans of text that serve as the two arguments for each discourse connective
predict the sense of the discourse connectives (e.g., "Cause", "Contrast")
Recognizing such discourse relations is an important part of natural language understanding, which benefits a wide range of natural language applications. More detail and examples.
What's new this year?

There are a few things. More detail will be provided later.
You can choose to do the task in English and/or Chinese.
You can choose to do the supplementary task, which is sense classification using gold standard argument pairs
Evaluation based on argument partial matching

Ready to join us?

We are glad that you are. The instructions are the same whether you would like to participate in both languages and/or just the supplementary task.
