+# ViMU: Benchmarking Video Metaphorical Understanding
+
+ViMU is a video understanding benchmark designed to evaluate whether multimodal models can go beyond literal perception and infer metaphorical, rhetorical, and socially grounded meanings in videos.
+
+Unlike standard video understanding datasets that focus mainly on objects, actions, events, or temporal relations, ViMU targets implicit subtext: what a video means beyond what is directly shown. The benchmark includes open-ended interpretation, evidence grounding, rhetoric mechanism identification, and social value signal identification.
+
+## Dataset Structure
+
+After downloading, the dataset should be organized as:
+
+```text
+ViMU/
+├── videos/
+│   ├── vimu_000001.mp4
+│   ├── vimu_000002.mp4
+│   └── ...
+├── metadata/
+│   ├── vimu_oe.jsonl
+│   ├── vimu_eg.jsonl
+│   ├── vimu_ss.jsonl
+│   ├── video_evidence.jsonl
+│   └── cache/
+│       ├── frames/
+│       └── transcripts/
+└── output/
+````
+
+The current uploaded archive may contain only a small subset of the full dataset for review or testing purposes.
+
+## Files
+
+### `videos/`
+
+This directory contains anonymized video files. Each video is named by its anonymous ID, for example:
+
+```text
+vimu_000001.mp4
+vimu_000002.mp4
+```
+
+### `metadata/vimu_oe.jsonl`
+
+Open-ended interpretation task. Each line corresponds to one video and contains:
+
+```json
+{
+  "video_id": "...",
+  "video_path": "...",
+  "taxonomy": {...},
+  "qa": {
+    "question": "...",
+    "answer": "...",
+    "short_reference_points": [...],
+    "grading_rubric": {...}
+  }
+}
+```
+
+This task asks models to answer a hint-free question about the video’s intended meaning.
+
+### `metadata/vimu_eg.jsonl`
+
+Evidence grounding task. Each line contains a multi-label question asking which video elements support the intended meaning.
+
+The candidate evidence sources include:
+
+```text
+visual scene / objects
+on-screen text
+spoken dialogue
+tone of voice
+editing transition
+```
+
+The fields include:
+
+```json
+{
+  "video_id": "...",
+  "question_type": "evidence_grounding",
+  "question": "...",
+  "intended_meaning": "...",
+  "options": {...},
+  "correct_options": [...],
+  "correct_labels": [...]
+}
+```
+
+### `metadata/vimu_ss.jsonl`
+
+Structured subtext task. Each line contains two multi-label multiple-choice tasks:
+
+```text
+rhetoric_mechanisms
+social_value_signals
+```
+
+Each task uses five macro-level categories labeled A--E.
+
+For rhetoric mechanisms:
+
+```text
+A. Literal / Direct
+B. Opposition / Incongruity
+C. Attitude / Tone-based Rhetoric
+D. Amplification / Stylization
+E. Implicit / Coded Social Framing
+```
+
+For social value signals:
+
+```text
+A. Neutral / No Social Signal
+B. Emotional Attitude
+C. Social Evaluation / Devaluation
+D. Norm and Value Framing
+E. Identity / Ideological Signaling
+```
+
+### `metadata/video_evidence.jsonl`
+
+Metadata used for model inference, including video paths, sampled frame paths, video duration, and ASR transcript.
+
+```json
+{
+  "video_id": "...",
+  "video_path": "...",
+  "duration_sec": 0.0,
+  "frames": [...],
+  "transcript": "..."
+}
+```
+
+### `metadata/cache/`
+
+Optional cached evidence used by the scripts:
+
+```text
+metadata/cache/frames/
+metadata/cache/transcripts/
+```
+
+## Recommended Placement
+
+After downloading the dataset, place it as:
+
+```text
+/path/to/ViMU/
+```
+
+Then update the code scripts by setting:
+
+```python
+PROJECT_ROOT = "/path/to/ViMU"
+```
+
+For example:
+
+```python
+PROJECT_ROOT = "/Users/anonymous/ViMU"
+```
+
+## Tasks
+
+ViMU contains four evaluation tasks:
+
+| Task                               | File                     | Format                      |
+| ---------------------------------- | ------------------------ | --------------------------- |
+| Open-ended interpretation          | `metadata/vimu_oe.jsonl` | Free-form generation        |
+| Evidence grounding                 | `metadata/vimu_eg.jsonl` | Multi-label multiple-choice |
+| Rhetoric mechanism identification  | `metadata/vimu_ss.jsonl` | Multi-label multiple-choice |
+| Social value signal identification | `metadata/vimu_ss.jsonl` | Multi-label multiple-choice |
