# IDIAPERS @ CASE22-TASK 3: Event Causality Identification
## Introduction
This repository contains official code for shared task 3 of [The 5th Workshop on Challenges and Applications of Automated Extraction of Socio-political Events from Text (CASE @ EMNLP 2022) ](https://emw.ku.edu.tr/case-2022/)
The task 3 was comprised of two subtasks. Given a sentence from the news-media:
* Subtask 1: identify whether sentence contains any causal relation,
* Subtask 2: extract all cause-effect-signal triplets capturing causal relations from this sentence.
Causality is a core cognitive concept and appears in many natural language processing (NLP) works that aim to tackle inference and understanding. Generally, a causal relation is a semantic relationship between two arguments known as cause and effect, in which the occurrence of one (cause argument) causes the occurrence of the other (effect argument). The Figure below illustrates some sentences that are marked as Causal and Non-causal respectively.

More information can be found at the [official challenge github](https://github.com/tanfiona/CausalNewsCorpus).
## Installation
The installation instructions for each subtask can be found in README located its respective folder (`subtask1` and `subtask2` respectively).
