## Pie Charts: Comparative Analysis of KG Approaches Across Metrics
### Overview
The image contains three pie charts comparing the distribution of three knowledge graph (KG) approaches across different metrics: CWQ(%), WebQSP(%), and GrailQA(%). Each chart uses three color-coded segments to represent:
- **KG Only** (blue)
- **LLM Inspired KG** (green)
- **KG Inspired LLM** (gray)
### Components/Axes
- **Legend**: Located at the bottom-right corner, mapping colors to categories.
- **Chart Labels**:
- Top-left: Metric name (e.g., "CWQ(%)")
- Bottom-left: Dominant category percentage (e.g., "77")
- **Segments**: Each chart divided into three proportional sections with embedded percentage labels.
### Detailed Analysis
#### CWQ(%)
- **KG Only**: 77% (blue, largest segment)
- **LLM Inspired KG**: 7% (green, smallest segment)
- **KG Inspired LLM**: 14% (gray, intermediate segment)
#### WebQSP(%)
- **KG Only**: 87% (blue, largest segment)
- **LLM Inspired KG**: 2% (green, smallest segment)
- **KG Inspired LLM**: 10% (gray, intermediate segment)
#### GrailQA(%)
- **KG Only**: 92% (blue, largest segment)
- **LLM Inspired KG**: 1% (green, smallest segment)
- **KG Inspired LLM**: 6% (gray, intermediate segment)
### Key Observations
1. **KG Only Dominance**:
- Consistently the largest segment across all metrics (77–92%).
- Shows a clear upward trend from CWQ(%) to GrailQA(%).
2. **LLM Inspired KG Decline**:
- Drops from 7% (CWQ) to 1% (GrailQA), indicating reduced relevance or adoption.
3. **KG Inspired LLM Stability**:
- Decreases moderately from 14% (CWQ) to 6% (GrailQA), suggesting partial but declining utility.
### Interpretation
The data suggests **KG Only** is the most effective or widely adopted approach across all metrics, with its dominance increasing as the metric complexity or specificity rises (CWQ → GrailQA). **LLM Inspired KG** shows a sharp decline, possibly due to limitations in handling structured KG tasks. **KG Inspired LLM** maintains a moderate presence but decreases slightly, indicating it may serve niche roles that diminish with higher metric specificity. The stark contrast between KG Only and other approaches highlights a potential trade-off between simplicity and performance in KG systems.
