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
(Hoyle et al., ACL 2025).

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

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).

topic	string	Primary topic label.
subtopic	string	Secondary topic label.
subjects_top_term	string	Top subject term for the bill.

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:

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))

    abstract = "Topic models and document-clustering evaluations either use automated metrics that align poorly with human preferences, or require expert labels that are intractable to scale. 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."
