Table 6 Correlation metric (\(1-\frac {(u-\bar {u}).(v-\bar {v})}{{\vert \vert u-\bar {u}\vert \vert }_{2}{\vert \vert v-\bar {v}\vert \vert }_{2}}\), with \(\bar {u}\), the mean of elements of u, and respectively \(\bar {v}\), the mean of elements of v) computed on the 285 concepts. A₁ to A₃ refers to human annotators and M₁ to M₁₀ refers to machine annotators through feature selection annotation on the +sm approach (considering the 10 K-Fold). U₁ (or +sm∪) is the union of subjects from the sets M₁ to M₁₀. Cells in are strictly superior to 0.5, cells in are between 0.25 and 0.5, cells in are strictly inferior to 0.25
