# SpecMind

**SpecMind** is a spectrum intelligence dataset released alongside the paper:

**“SpecMind: Enabling Spectrum Intelligence via Multi-Agent Hybrid Retrieval-Augmented Generation.”**

This repository contains two complementary components:

1. a heterogeneous **spectrum knowledge dataset**, and
2. **SpecBench**, an expert-designed benchmark for evaluating retrieval-augmented generation (RAG) systems in the spectrum domain.

The dataset supports research on retrieval and reasoning across structured, textual, and graph-oriented spectrum information.

## Dataset Components

### Spectrum Knowledge Dataset

The knowledge dataset contains three types of spectrum-domain information:

- **License data** — structured spectrum licensing records with numerical and categorical attributes.
- **Proceeding documents** — FCC proceeding comments and reply comments involving multiple stakeholders and regulatory topics.
- **Regulatory documents** — codified spectrum rules and policies, including FCC regulatory text.

These sources are used by SpecMind with modality-aware retrieval mechanisms: SQL-based retrieval for license data, graph-based retrieval for proceedings, and dense retrieval for regulatory text.

The proceeding collection used in the accompanying work includes:

- FCC 19-38
- FCC 24-72
- FCC 25-59
- FCC 22-352
- FCC 23-158
- FCC 23-232
- NTIA National Spectrum Strategy

### SpecBench

**SpecBench** is a Q&A benchmark for evaluating RAG systems over heterogeneous spectrum data.

It contains **450 curated question-answer pairs** based on realistic spectrum-analysis tasks and evidence from the accompanying knowledge sources.

SpecBench evaluates three core capabilities:

- **Noise Robustness** — retrieving the correct evidence despite irrelevant or noisy information.
- **Information Integration** — combining evidence across multiple documents, records, or data sources.
- **Negative Rejection** — recognizing when sufficient evidence is unavailable and avoiding unsupported answers.

## Question Categories

SpecBench contains five major categories:

| Category | Data Source | Main Capability |
|---|---|---|
| Proceeding | Proceeding documents | Noise robustness / information integration |
| License | License records | Noise robustness / information integration |
| Regulation | FCC Title 47 | Information integration |
| Compound | Multiple data sources | Information integration |
| Unanswerable | No valid evidence | Negative rejection |

Proceeding and license questions include both single-evidence and multi-evidence tasks.

Compound questions are further divided into:

- **Parallel:** evidence can be retrieved independently from different sources and combined in the final answer.
- **Sequential:** results from one retrieval step are required to formulate or constrain subsequent retrieval steps.

The benchmark distribution is:

| Category | Percentage |
|---|---:|
| Proceeding | 31.1% |
| License | 31.1% |
| Regulation | 13.3% |
| Compound | 14.4% |
| Unanswerable | 10.0% |

Regulation questions also include adapted samples from the **WiLL benchmark**.

## Repository Structure

```text
SpecMind/
├── knowledge/

```

The `knowledge/` directory contains the spectrum-domain resources used for retrieval.

The `benchmark/` directory contains SpecBench questions, reference answers, and associated evaluation information.

## Intended Uses

This dataset is intended for research on:

- retrieval-augmented generation,
- multi-agent and agentic RAG,
- spectrum policy and regulatory question answering,
- heterogeneous information retrieval,
- structured and graph-based retrieval,
- cross-source reasoning, and
- hallucination and negative-rejection evaluation.

## SpecMind Framework

The accompanying **SpecMind** framework uses specialized agents for different knowledge sources:

- **License Agent** — SQL-based retrieval over structured license data.
- **Proceeding Agent** — graph-based retrieval over proceeding documents.
- **Regulation Agent** — dense retrieval and reranking over regulatory text.

A Supervisor Agent coordinates these components for multi-source spectrum reasoning.

## Limitations

SpecBench covers a selected collection of spectrum data sources and task types and is not intended to represent all spectrum-management scenarios.

Results may depend on the underlying language model, retrieval implementation, database construction, and prompting strategy.

This dataset is intended for research purposes. For legal, regulatory, licensing, or operational decisions, users should consult the original authoritative sources.

## Licensing and Source Documents

The repository contains materials originating from multiple spectrum-domain sources.

Copyright and licensing conditions may vary across source documents. Redistribution through this repository does not replace or modify the terms associated with the original material.

Users should consult the original source for applicable licensing and usage conditions.

Licensing terms for SpecBench annotations and other original dataset components will be specified separately where applicable.
