## Flowchart: Question Answering Process for Sponsorship Identification
### Overview
The flowchart illustrates a structured process to answer the question: *"The 2017–18 Wigan Athletic F.C. season will be a year in which the team competes in the league cup known as what for sponsorship reasons?"* It breaks the problem into decomposition, retrieval, and reasoning/self-verification steps, using color-coded blocks (red, green, blue) to represent each phase.
### Components/Axes
- **Decomposition (Red Block)**:
- **Sub-question 1**: *"What league cup is the Wigan Athletic F.C. competing in during the 2017-18 season?"*
- **Sub-question 2**: *"What is the name of the league cup from the 2017-18 Wigan Athletic F.C. season?"*
- **State**: *"End."*
- **Retrieval (Green Block)**:
- **Entity Extraction**:
- `"Wigan Athletic F.C."`, `"2017–18 season"`, `"league cup"`, `"sponsorship reasons"`.
- **Triple Extraction**:
- Triples like `("Wigan Athletic F.C.", "competes in", "league cup")`, `("2017–18 season", "associated with", "Wigan Athletic F.C.")`, and `("league cup", "sponsorship name", "unknown")`.
- **Subgraph**:
- Relationships such as `("Wigan Athletic F.C.", "competes in", "league cup")` and `("league cup", "sponsorship name", "Carabao Cup")`.
- **Reasoning and Self-Verification (Blue Block)**:
- **Verification Steps**:
1. *"In which league cup did Wigan Athletic F.C. compete during the 2017–18 season?"* → Answer: `"EFL Cup"`.
2. *"What was the sponsored name of the league cup identified in sub-question #1 during the 2017–18 season?"* → Answer: `"Carabao Cup"`.
### Content Details
- **Decomposition**:
- The question is split into two sub-questions to isolate the league cup name and its sponsorship name.
- **Retrieval**:
- Entities and triples are extracted from a knowledge graph, linking the team, season, league cup, and sponsorship.
- The subgraph confirms the league cup as the `"EFL Cup"` (official name: `"Carabao Cup"`).
- **Reasoning**:
- Self-verification cross-checks answers using retrieved data, ensuring consistency.
### Key Observations
- The flowchart emphasizes **modular problem-solving**, breaking the question into smaller, verifiable components.
- The answer `"Carabao Cup"` is derived through iterative validation of retrieved triples.
- The `"sponsorship name"` triple initially marked as `"unknown"` is resolved to `"Carabao Cup"` in the final step.
### Interpretation
The flowchart demonstrates a **knowledge graph-based QA system** where:
1. **Decomposition** reduces ambiguity by isolating sub-problems.
2. **Retrieval** leverages structured data (entities/triples) to populate knowledge gaps.
3. **Self-verification** ensures answers align with retrieved facts, avoiding hallucinations.
The process highlights how sponsorship names (e.g., `"Carabao Cup"`) are dynamically linked to league cups via temporal and contextual relationships in the knowledge graph. The use of color coding aids in tracing the flow of logic from question decomposition to final answer validation.
