Table 9 Indicators of graph-based retrieval model performance
From: Characterizing the hypergraph-of-entity and the structural impact of its extensions
Ranking indicators | Anomaly indicators | ||
|---|---|---|---|
Cl. coef. | Ascending order \(\sim\) 50% correlated with retrieval performance | Degree | Abnormally high values (\(> \mu + 2\sigma\)) indicate a low performing model |
Density | Descending order \(\sim\) 50% correlated with retrieval performance | Diameter | Abnormally low values (\(< \mu - 2\sigma\)) indicate a low performing model |
