From: Synonym extraction and abbreviation expansion with ensembles of semantic spaces
For each of the 2 corpora, 10 semantic spaces were induced. | |||||||
RI spaces | RI_20 | RI_2 | RI_4 | RI_8 | |||
RP spaces | RP_2 | RP_2_sw | RP_4 | RP_4_sw | RP_8 | RP_8_sw | |
The induced semantic spaces were combined in 10 different combinations. | |||||||
Combinations | |||||||
Identical window size | RI_2, RP_2 | RI_4, RP_4 | RI_8, RP_8 | ||||
Identical window size, stop words | RI_2, RP_2_sw | RI_4, RP_4_sw | RI_8, RP_8_sw | ||||
Large window size | RI_20, RP_2 | RI_20, RP_4 | |||||
Large window size, stop words | RI_20, RP_2_sw | RI_20, RP_4_sw | |||||
For each combination, 3 combination strategies were evaluated. | |||||||
Combination strategies | RI ⊂ RP30 | RP ⊂ RI30 | RI + R P |
