📜 ProofWalaDataset

The ProofWalaDataset is a multilingual dataset of formal theorem proving traces collected from multiple interactive theorem prover (ITP) ecosystems. It provides a structured view of proof steps, goals, hypotheses, and theorem names from diverse mathematical and program verification libraries.

This dataset is intended for researchers and practitioners working on:

Automated theorem proving
Formal code generation
Machine learning for logic
Proof step prediction
Multi-language transfer in formal systems

📂 Dataset Structure

The dataset is organized into the following ITP families:

lean/
coq/
GeoCoq/
math-comp/
multilingual/ (cross-formal-language hybrid)

Each family includes standard splits:
train/, test/, and eval/, each containing multiple JSON files.
Each JSON file contains a top-level key: "training_data" with a list of proof records.

🔍 Each record contains

Field	Description
`proof_id`	Unique identifier for the proof trace
`goal_description`	Optional natural language description of the proof
`start_goals`	List of starting goals (each with `goal` and `hypotheses`)
`end_goals`	Final goals after applying proof steps
`proof_steps`	List of applied proof tactics (`inv`, `rewrite`, etc.)
`simplified_goals`	Simplified representations of goals (if any)
`all_useful_defns_theorems`	Set of useful definitions or theorems (static analysis)
`addition_state_info`	Optional additional metadata about the proof context
`file_path`	Source file where the proof appears
`project_id`	The ITP project or repository path (e.g., CompCert)
`theorem_name`	Name of the theorem being proved

For convenience, structured fields such as start_goals[*].goal, start_goals[*].hypotheses, end_goals[*].goal, and end_goals[*].hypotheses are exposed directly through the Croissant metadata.

🧠 Use Cases

Pretraining and finetuning LLMs for formal verification
Evaluating proof search strategies
Building cross-language proof translators
Fine-grained proof tactic prediction
