 # Can Large Language Models Help Multimodal Language Analysis? MMLA: A Comprehensive Benchmark
 
+## Introduction
+
 MMLA is the first comprehensive multimodal language analysis benchmark for evaluating foundation models. It has the following features:
 
 - **Large** Scale: 61K+ multimodal samples.

 - Both **Acting** and **Real-world** Scenarios: films, TV series, YouTube, Vimeo, Bilibili, TED, improvised scripts, etc.
 - **Six** Core Dimensions in Multimodal Language Analysis: intent, emotion, sentiment, dialogue act, speaking style, and communication behavior.
 
+We also build baselines with three evaluation methods (i.e., zero-shot inference, supervised fine-tuning, and instruction tuning) on 8 mainstream foundation models (i.e., 5 MLLMs (Qwen2-VL, VideoLLaMA2, LLaVA-Video, LLaVA-OV, MiniCPM-V-2.6), 3 LLMs (InternLM2.5, Qwen2, LLaMA3). More details can refer to our [paper](https://arxiv.org/abs/2504.16427).

+## Datasets
+
+### Statistics 
+
+Dataset statistics for each dimension in the MMLA benchmark. #C, #U, #Train, #Val, and #Test represent the number of label classes, utterances, training, validation, and testing samples, respectively. avg. and max. refer to the average and maximum lengths.

We fully respect the datasets’ copyright policies, license requirements, and ethical standards. For those datasets whose licenses explicitly permit redistribution, we release the original video data (e.g., [MIntRec](https://github.com/thuiar/MIntRec), [MIntRec2.0](https://github.com/thuiar/MIntRec2.0), [MELD](https://github.com/declare-lab/MELD), [UR-FUNNY-v2](https://github.com/ROC-HCI/UR-FUNNY), [MUStARD](https://github.com/soujanyaporia/MUStARD), [MELD-DA](https://github.com/sahatulika15/EMOTyDA), [CH-SIMS v2.0](https://github.com/thuiar/ch-sims-v2), and [Anno-MI](https://github.com/uccollab/AnnoMI).

In compliance with all relevant licenses, we also provide the original textual data unchanged, together with the specific dataset splits used in our experiments.
