# Screenplay Scene Salience Features

Pre-extracted linguistic and narrative features for screenplay scene salience detection from the MENSA dataset.

## Dataset Description

This dataset contains **913 linguistic features** extracted from movie screenplays in the MENSA dataset. Features are organized into **24 feature groups** covering various aspects of linguistic, narrative, and discourse analysis.

### Dataset Statistics

## Usage

### Option 1: Load with Hugging Face datasets (Recommended)

```python
from datasets import load_dataset

# Load a single feature group
ds = load_dataset("Ishaank18/screenplay-features", data_files="train/base.parquet")
df = ds['train'].to_pandas()

# Load multiple groups for training
ds = load_dataset("Ishaank18/screenplay-features", 
                  data_files={
                      "train": ["train/base.parquet", "train/gc_polarity.parquet", "train/emotional.parquet"]
                  })
df = ds['train'].to_pandas()

# Load all splits for evaluation
ds = load_dataset("Ishaank18/screenplay-features",
                  data_files={
                      "train": "train/gc_polarity.parquet",
                      "validation": "validation/gc_polarity.parquet",
                      "test": "test/gc_polarity.parquet"
                  })
```

### Option 2: Load with pandas directly

```python
import pandas as pd

# From HuggingFace URL
df = pd.read_parquet("hf://datasets/Ishaank18/screenplay-features/train/base.parquet")

# Or if you have the repo cloned locally
df = pd.read_parquet("train/base.parquet")
```

### Option 3: Use custom loader (Easiest)

```python
from feature_cache.load_hf import load_groups

# Load features and labels
X, y = load_groups(
    groups=["base", "gc_polarity", "emotional", "rst"],
    split="train",
    hf_repo="Ishaank18/screenplay-features"
)

# Load features only (no labels)
X = load_groups(
    groups=["base", "gc_polarity"],
    split="test",
    include_label=False,
    hf_repo="Ishaank18/screenplay-features"
)
```

## Data Structure

Each parquet file contains:

- **`movie_id`** (string): Unique movie identifier
- **`scene_index`** (int): Scene index within the movie (0-indexed)
- **`label`** (int): Salience label
  - `0` = Non-salient scene
  - `1` = Salient scene
- **Feature columns**: Various linguistic/narrative features (float/int)

### Example row structure:

| movie_id | scene_index | label | feature_1 | feature_2 | ... |
|----------|-------------|-------|-----------|-----------|-----|
| tt0111161 | 42 | 1 | 0.85 | 12.3 | ... |
