SemEval 2024 Task: Emotion Discovery and Reasoning its Flip in Conversation (EDiReF) |
The EDiReF shared task at SemEval 2024 is an amalgamation of three subtasks tasks- (i) Emotion Recognition in Conversation (ERC) in Hindi-English code-mixed conversations, (ii) Emotion Flip Reasoning (EFR) in Hindi-English code-mixed conversations, and (iii) EFR in English conversations. The definition for the tasks of ERC and EFR are as illustrated below:
- ERC: Given a dialogue, ERC aims to assign an emotion to each utterance from a predefined set of possible emotions.
- EFR: Given a dialogue, EFR aims to identify the trigger utterance(s) for an emotion-flip in a multi-party conversation dialogue.
For example, given a sample dialogue below:
| Speaker | Utterance |
|---|---|
| Sp1 | I had an awful day today! |
| Sp2 | Oh no! What happened? |
| Sp1 | Somebody ate my sandwich! |
| Sp2 | I can make you a new one right now! |
| Sp1 | That would be great! Thanks! |
ERC aims to assign emotions to each utterance
| Speaker | Utterance | Emotion |
|---|---|---|
| Sp1 | I had an awful day today! | Sad |
| Sp2 | Oh no! What happened? | Sad |
| Sp1 | Somebody ate my sandwich! | Sad |
| Sp2 | I can make you a new one right now! | Joy |
| Sp1 | That would be great! Thanks! | Joy |
The example dialogue has two emotion flips. Sp1's emotion changed from Sad to Joy while Sp2's emotion also shifted from Sad to joy. EFR aims to justify such emotion flips using triggers.
| Speaker | Utterance | Emotion | Trigger |
|---|---|---|---|
| Sp1 | I had an awful day today! | Sad | 0 |
| Sp2 | Oh no! What happened? | Sad | 0 |
| Sp1 | Somebody ate my sandwich! | Sad | 0 |
| Sp2 | I can make you a new one right now! | Joy | 1 |
| Sp1 | That would be great! Thanks! | Joy | 0 |
