# PROXANN Data

**PROXANN Data** provides the corpora used for training and evaluating topic models in  
**[PROXANN: Use-Oriented Evaluations of Topic Models and Document Clustering](https://aclanthology.org/2025.acl-long.772/)**  
(Hoyle *et al.*, ACL 2025).

This repository contains two dataset — **Bills** and **Wiki** — each with **training** (with contextualized embeddings) and **test** (metadata-only) splits.

## Structure

| Split | File | Rows | Description |
| ------|------|------:|-------------|
| `bills_train` | `bills_train.metadata.embeddings.jsonl.all-MiniLM-L6-v2.parquet` | 32,661 | Congressional bills with summaries, topics, and 384-dim embeddings. |
| `bills_test`  | `bills_test.metadata.parquet` | 15,242 | Bills test split without embeddings (metadata only). |
| `wiki_train`  | `wiki_train.metadata.embeddings.jsonl.all-MiniLM-L6-v2.parquet` | 14,290 | Wikipedia articles with categories and 384-dim embeddings. |
| `wiki_test`   | `wiki_test.metadata.parquet` | 8,024 | Wikipedia test split without embeddings (metadata only). |

## Columns

### Bills (`bills_train` / `bills_test`)

| Column | Type | Description |
| ------- | ---- | ----------- |
| `id` | string | Unique identifier. |
| `summary` | string | Short summary of the bill. |
| `topic` | string | Primary topic label. |
| `subtopic` | string | Secondary topic label. |
| `subjects_top_term` | string | Top subject term for the bill. |
| `date` | string | Document date (ISO-8601 format). |
| `tokenized_text` | list[string] | Preprocessed tokens from Hoyle et al. (2022), 15 k vocabulary. |
| `embeddings` | list[float] (384) | Sentence embedding (MiniLM-L6-v2). *Absent in test split.* |

### Wiki (`wiki_train` / `wiki_test`)

| Column | Type | Description |
| ------- | ---- | ----------- |
| `id` | string | Unique identifier. |
| `text` | string | Article text (raw or normalized). |
| `supercategory` | string | High-level category. |
| `category` | string | Primary category. |
| `subcategory` | string | Secondary category. |
| `page_name` | string | Wikipedia page title. |
| `tokenized_text` | list[string] | Preprocessed tokens from Hoyle et al. (2022), 15 k vocabulary. |
| `embeddings` | list[float] (384) | Sentence embedding (MiniLM-L6-v2). *Absent in test split.* |


## Vocabularies

The dataset includes the **15k-token vocabularies** used during preprocessing and model training.  
Each file is a JSON mapping of **token -> integer index** (0–14,999).

| File | Description |
|------|-------------|
| `data_with_embeddings/vocabs/bills_vocab.json` | Vocabulary for the Bills corpus. Keys are tokens, values are integer indices. |
| `data_with_embeddings/vocabs/wiki_vocab.json`  | Vocabulary for the Wiki corpus. Keys are tokens, values are integer indices. |

## Usage Example
The dataset contains four Parquet files:

- `bills_train`  
- `bills_test`  
- `wiki_train`  
- `wiki_test`

Because the Bills and Wiki splits use different schemas, you should load each split
directly from its Parquet file using the generic `parquet` loader from 🤗 Datasets:

```python
from datasets import load_dataset

# ------------------------------
# Bills Dataset
# ------------------------------
bills_train = load_dataset(
    "parquet",
    data_files={
        "train": "hf://datasets/lcalvobartolome/proxann_data@main/"
                 "bills_train.metadata.embeddings.jsonl.all-MiniLM-L6-v2.parquet"
    },
    split="train",
)
print("Bills train size:", len(bills_train))   # 32661

bills_test = load_dataset(
    "parquet",
    data_files={
        "test": "hf://datasets/lcalvobartolome/proxann_data@main/"
                "bills_test.metadata.parquet"
    },
    split="test",
)
print("Bills test size:", len(bills_test))     # 15242


# ------------------------------
# Wiki Dataset
# ------------------------------
wiki_train = load_dataset(
    "parquet",
    data_files={
        "train": "hf://datasets/lcalvobartolome/proxann_data@main/"
                 "wiki_train.metadata.embeddings.jsonl.all-MiniLM-L6-v2.parquet"
    },
    split="train",
)
print("Wiki train size:", len(wiki_train))     # 14290

wiki_test = load_dataset(
    "parquet",
    data_files={
        "test": "hf://datasets/lcalvobartolome/proxann_data@main/"
                "wiki_test.metadata.parquet"
    },
    split="test",
)
print("Wiki test size:", len(wiki_test))
```

We design a scalable human evaluation protocol and a corresponding automated approximation that reflect practitioners' real-world usage of models. Annotators{---}or an LLM-based proxy{---}review text items assigned to a topic or cluster, infer a category for the group, then apply that category to other documents. Using this protocol, we collect extensive crowdworker annotations of outputs from a diverse set of topic models on two datasets. We then use these annotations to validate automated proxies, finding that the best LLM proxy is statistically indistinguishable from a human annotator and can therefore serve as a reasonable substitute in automated evaluations."
