Schema-Based Mediation
A semantic mediation approach that matches user prompt vocabulary to database schema elements via semantic similarity. It handles only lexical or shallow semantic associations and cannot capture complex relationships among entities.

A Design Science Research paper compared two semantic mediation approaches through simulation-based evaluation and found that the knowledge-graph-based path won across the board on precision, recall and user intent preservation.
Schema-based mediation matches terms in the user prompt to database schema elements via semantic similarity, but cannot capture the complex relationships among entities.
The evaluation results show that knowledge-graph-based mediation outperforms the schema-based method on all four dimensions: precision, recall, F1 score and user intent preservation.
