| Challenge: | Existing methods based on semantic similarity work well only on simplified datasets . Existing approaches based only on semantic similarities struggle to handle complex tables . |
| Approach: | They propose a graph-based framework that leverages human-curated relational knowledge to explicitly encode schema links and join paths. |
| Outcome: | The proposed framework leverages human-curated relational knowledge to encode schema links and join paths. |
