  1. P-values for the differences between the recall results on the synonym task for the semantic spaces/ensembles presented in Table 10. P-values showing a statistically significant difference (p-value < 0.05) are presented in bold-face.
  2. P-values for the post-processing and for the abbr →exp and exp →abbr are not shown in the table. However, for the significance level p-value < 0.05, there were no statistically significant recall difference between the standard Disjoint Corpora Ensemble and the post-processing version for any of the three tasks (p-value = 0.25 for abbr →exp and p-value = 0.062 for exp →abbr). When testing the recall difference between the pairs of semantic spaces/ensembles shown in Table 10 for the abbr →exp task, there was only a significant difference for the pairs Medical Space vs. Clinical Ensemble (p-value = 0.039), Medical Space vs. Disjoint Corpora Ensemble (p-value = 0.004) and Medical Ensemble vs. Disjoint Corpora Ensemble (p-value = 0.039). For the exp →abbr task, there were no statistically significant differences.
