+# Emotion-Cause-in-Friends (ECF)
+
+For the task named Multimodal Emotion-Cause Pair Extraction in Conversation, we accordingly construct a multimodal conversational emotion cause dataset ECF (1.0). For SemEval 2024 task 3, we have furthermore annotated an extended test set as the evaluation data. *Note*: ECF (1.0) and the extended test set for SemEval evaluation constitute ECF 2.0.

+## About Multimodal Data   
+
+⚠️ Due to potential copyright issues with the TV show "Friends", we cannot provide pre-segmented video clips. 
+
+If you need to utilize multimodal data, you may consider the following options:
+
+1. Use the acoustic and visual features we provide:
+    - [`audio_embedding_6373.npy`](https://drive.google.com/file/d/1EhU2jFSr_Vi67Wdu1ARJozrTJtgiQrQI/view?usp=share_link): the embedding table composed of the 6373-dimensional acoustic features of each utterances extracted with openSMILE
+    - [`video_embedding_4096.npy`](https://drive.google.com/file/d/1NGSsiQYDTqgen_g9qndSuha29JA60x14/view?usp=share_link): the embedding table composed of the 4096-dimensional visual features of each utterances extracted with 3D-CNN
+    - Please note that the above features only include the original ECF (1.0) dataset; the SemEval evaluation data is not included. If needed, you can contact us, and we will do our best to release new features.
+  
+2. You can download the raw video clips from [MELD](https://github.com/declare-lab/MELD). Since ECF (1.0) is constructed based on the MELD dataset, most utterances in ECF (1.0) correspond to those in MELD. The correspondence can be found in the last column of the file [all_data_pair_ECFvsMELD.txt](https://github.com/NUSTM/MECPE/blob/main/data/all_data_pair_ECFvsMELD.txt). However, **we have made certain modifications to MELD's raw data while constructing ECF, including but not limited to editing utterance text, adjusting timestamps, and adding or removing utterances**. Therefore, some timestamps provided in ECF (1.0) have been corrected and may differ from those in MELD. There are also new utterances that cannot be found in MELD. Given this, we recommend option (3) if feasible.
+
+3. Download the raw videos of _Friends_ from the website, and use the FFmpeg toolkit to extract audio-visual clips of each utterance based on the timestamps we provide.

+# Dataset for SemEval-2024 Task 3
+
+The dataset ECF 2.0 for [**SemEval-2024 Task 3: Multimodal Emotion Cause Analysis in Conversations**](https://aclanthology.org/2024.semeval-1.277) is released here.
+
+In our preliminary work [MECPE](https://github.com/NUSTM/MECPE), we constructed the **ECF (1.0)** dataset. For this SemEval competition, **the entire ECF (1.0) dataset serves as the training data**, and we have **additionally annotated a new test set** as the evaluation data, together constituting the **ECF 2.0** dataset.
+
+
+## File Description
+
+- The files `Subtask_1_train.json` and `Subtask_2_train.json` contain the training data for two subtasks in SemEval 2024, where all instances are stacked into a list and each of them is stored in a dictionary. The files `Subtask_1_test.json` and `Subtask_2_test.json` contain the evaluation data, using the same format. 
+- For Subtask 2, you can refer to the JSON files to obtain **timestamps** and download the raw videos from the website to process the multimodal data.  ⚠️ **Due to potential copyright issues, we do not provide pre-segmented video clips.**
+
+📢 Note: To ensure the fairness of our competition, the evaluation data released during the evaluation phase of SemEval 2024 included some noise data that was not intended for evaluation. In the newly released version, the noise data has been removed, and the labels have been made publicly available.
