## HillStreet: A Relational Dataset for Evaluating Information Channels in Congressional Trading

**HillStreet** is a large-scale, longitudinal dataset and multimodal dynamic graph formalizing the intersection of Capitol Hill and Wall Street. It spans **13.5 years** of mandatory STOCK Act disclosures (July 2012–December 2025), unifying the congressional trading ecosystem into a single, machine-learning-ready framework.

### Dataset Summary
The dataset represents the relationship between **1,137 legislators** and **6,825 companies**. By framing congressional trading as a **dynamic bipartite graph**, HillStreet allows researchers to treat trade signal validation as an edge classification task.

- **Nodes:** Legislators (session-specific) and Publicly Traded Companies.
- **Target Edges:** Individual stock trades.
- **Structural Edges:** Lobbying records, campaign finance (PAC/527) contributions, and geographical/industrial-constituency alignments.

### Dataset Structure

HillStreet is divided into pre-built graph objects for deep learning and a relational tabular database accessed via Hugging Face configurations.

#### 1. Dynamic Graph Objects (`.pt` & `.npy`)
For immediate use in Graph Neural Networks (GNNs) and Temporal Graph Networks (TGNs), the core of HillStreet consists of annual **PyTorch Geometric Temporal** objects.
- **Graph Files:** `hillstreet_temporal_graph_YEAR.pt`
- **Temporal Integrity:** Every node feature and edge is instantiated based on its **public disclosure date**, not its reference date, ensuring a look-ahead-bias-free environment for backtesting.
- **Node Features:** Includes rolling DW-NOMINATE scores, SEC fiscal facts, and Census district employment statistics.
- **ID Mappings:** `src_id_map.npy` (Legislator Bioguide IDs) and `dst_id_map.npy` (Company Tickers).

#### 2. Relational Tables (Hugging Face Configs)
For researchers using flat-feature models (XGBoost, LightGBM) or custom graph builders, the structural connective tissue is provided as multiple dataset configurations. You can load these individually using the Hugging Face `datasets` library (e.g., `load_dataset("benroodman/HillStreet", "processed_events_lobbying")`).

**Processed Edge Tables:**
- `processed_events_lobbying`: Mappings of legislative activity to corporate nodes.
- `processed_events_campaign_finance`: Itemized PAC/527 donations broadcasted to corporate sectors.
- `processed_events_geographical_industry`: Industrial-constituency edges linking legislators to companies in their districts.

**Raw Source Tables:**
The raw, underlying tables are also available as distinct configurations for custom aggregations and feature engineering:
- **Campaign Finance:** `raw_cf_*` and `raw_527_*` configs.
- **Legislator Data:** `raw_voteview_*` configs and `raw_committee_assignments`.
- **Corporate & Industry:** `raw_sec_financials`, `raw_naics_*` crosswalks, and `raw_district_industries_*` configs.
- **Lobbying:** `raw_lobbyview_*` configs.

### Feature Engineering & Normalization
To stabilize variance in graph training, continuous features are transformed using signed log-scaling:
$$x' = \text{sign}(x) \times \log(1 + |x|)$$

### Intended Use
- **Trade Signal Validation:** Determining if a trade constitutes a meaningful price signal based on political context.
- **Graph Representation Learning:** A benchmark for GNNs and TGNs.

> [!WARNING]
> **Non-Intended Use:** This dataset is for research purposes only. It is not designed for legal determinations of insider trading nor for real-time automated trading.
