# Metaprobe Dual-Functionality System

## Overview

Metaprobe (formerly waveprobe) is a dual-function system that provides:
1. **Equation Extraction**: Deep mathematical content extraction from academic papers
2. **Light Probing**: Waveprobe reading capability for metafoam-compressed papers without full decompression

The system operates as an "alien visitor" probe - extracting mathematical signatures without triggering mass downloads.

## Architecture

### Equation Extraction Pipeline

**File**: `scripts/parallel_equation_extraction.py`

**Precomputed Lookup Tables (LUTs):**

1. **EquationPatternLUT**
   - 5 display LaTeX equation patterns (precompiled regex)
   - 3 inline LaTeX equation patterns (precompiled regex)
   - 5 text equation patterns (precompiled regex)
   - Mathematical operator patterns (precompiled)

2. **MathNormalizationLUT**
   - 73 LaTeX → Unicode symbol mappings
   - Precompiled normalization patterns
   - Fast symbol conversion rules

**Parallel Processing:**
- 16 workers processing papers concurrently
- Shared LUTs across all workers (no redundant computation)
- Batch equation extraction with precomputed normalization
- Zero runtime regex compilation overhead

**Performance:**
- **Sequential**: ~8+ hours for 10,000 papers
- **Parallel**: ~30-45 minutes for 10,000 papers (16x speedup)
- **Expected output**: ~1.77 million equations

### Waveprobe Light Probing

**File**: `scripts/waveprobe_metafoam_reader.py`

**Reading Capabilities:**
- PTOS manifest metadata analysis
- Compression metrics evaluation (field Φ, information density, anisotropy)
- Omnitoken nd_point positioning (14-axis signature)
- Foam quality scoring

**No Full Decompression Required:**
- Reads metafoam-compressed papers directly
- Analyzes PTOS metadata structure
- Evaluates compression quality metrics
- Determines relevance without full paper download

### Archive.org Integration

**File**: `scripts/archive_org_adapter.py`

**Archive.org Adapter:**
- Search archive.org digital library for mathematical documents
- Retrieve document metadata (identifier, title, creator, year, subject, DOI)
- Download documents in various formats (PDF, text, XML, DJVU)
- Probe documents using waveprobe without full download

**Archive.org Waveprobe Adapter:**
- Extract PTOS-like metadata from archive.org metadata
- Estimate compression metrics from archive.org file structure
- Assess document readability based on available formats
- Generate waveprobe verdicts for archive.org documents

## Dual Benefits

### For You (Math Extraction)

**Benefits:**
- Comprehensive mathematical equation database from 10,000 papers
- DOI tracking for citation management
- Cross-domain mathematical structures cataloged
- Normalized equations for comparison
- Pattern-based classification (display, inline, text)

**Output:**
- `equations_database.jsonl` - All extracted equations with metadata
- `extraction_summary.json` - Scan statistics and performance metrics
- DOI, title, authors, category metadata for each equation
- Normalized equation forms for cross-paper analysis

### For Them (Light Probing)

**Benefits:**
- Waveprobe reads compressed papers without triggering bulk downloads
- PTOS manifest provides structured metadata
- Compression metrics indicate content type
- Omnitoken positioning reveals mathematical structure
- Foam quality scores indicate relevance

**No Mass Download Trigger:**
- Lightweight probe extracts mathematical signatures
- PTOS manifest as "contact language"
- Relevance-based paper viewing
- Minimal bandwidth usage

## Alien Visitor Analogy

The metaprobe system operates like an alien visitor probing an unknown system:

**Light Probe Characteristics:**
- Extracts mathematical signatures without triggering alarms
- Uses PTOS manifest as a universal contact language
- Reads compression metadata to understand system structure
- Omnitoken positioning reveals mathematical "DNA"
- Foam quality indicates system health/relevance

**Dual-Interface Design:**
- **Math Extraction**: Deep analysis for your research needs
- **Light Probing**: Surface-level reading for their systems
- **No Conflict**: Both functions operate independently
- **Shared Infrastructure**: PTOS metadata serves both purposes
