# Technical Document Extraction
## Tree Structure
- **Root Node**: Labeled "Root" (gray circle)
- **Head 1** (pink box):
- Connected to "It" (white circle)
- Connected to "I" (white circle)
- **Head 2** (orange box):
- Connected to "is" (white circle)
- Connected to "'" (white circle)
- Connected to "the" (white circle)
- **Tree Mask**: Labeled at bottom left (green tree icon)
## Key
- **Color-Coded Groups**:
1. **Head 1** (pink):
- "It"
- "I"
2. **Head 2** (orange):
- "is"
- "'"
- "the"
3. **Query** (yellow):
- "is"
- "'"
- "the"
## Heatmap Grid
- **Rows**: Labeled "Head 1" and "Head 2"
- **Columns**: Labeled with query words ("is", "'", "the")
- **Checkmarks** (blue checkmarks) indicate matches between query words and heads:
- **Head 1 Row**:
- Column "It": ✅
- Column "I": ✅
- **Head 2 Row**:
- Column "is": ✅
- Column "'": ✅
- Column "the": ✅
## Diagram Flow
1. **Root** branches to **Head 1** and **Head 2**.
2. **Head 1** contains "It" and "I".
3. **Head 2** contains repeated sequences of "is", "'", "the".
4. **Query** words ("is", "'", "the") are compared against heads via the heatmap.
5. **Tree Mask** visually represents the hierarchical structure.
## Key Trends
- **Head 1** matches only its own words ("It", "I").
- **Head 2** matches all query words ("is", "'", "the") due to repetition.
- The heatmap reveals **Head 2** has higher query coverage (6/6 matches) vs. **Head 1** (2/2 matches).
