Characteristics of the data by dimension of the CogPO ontology and label sets.
| Dimension | # Labels | LCavg | LCmax | PUNIQ | Pmin | k |
|---|---|---|---|---|---|---|
| Behavioral domain | 40 | 1.846 | 8 | 0.429 | 0.413 | 9 |
| Cognitive paradigm class | 48 | 1.291 | 4 | 0.336 | 0.761 | 8 |
| Instruction type | 14 | 1.648 | 6 | 0.251 | 0.510 | 17 |
| Response modality | 5 | 1.308 | 3 | 0.036 | 0.700 | 21 |
| Response type | 9 | 1.324 | 4 | 0.069 | 0.696 | 10 |
| Stimulus modality | 5 | 1.150 | 3 | 0.036 | 0.858 | 25 |
| Stimulus type | 17 | 1.494 | 4 | 0.247 | 0.587 | 8 |
LCavg, LCmax = average and maximum number of labels per instance, respectively; PUNIQ = ratio of unique label combinations/sample size (247); Pmin = proportion with the minimum number of labels (always 1, in this dataset); k = value set for the kNN algorithm, see section 2.3.
