Soft cardinality has been shown to be a very strong text-overlapping baseline for the task of measuring semantic textual similarity (STS), obtaining 3rd place in SemEval-2012. At *SEM-2013 shared task, beside the plain text- overlapping approach, we tested within soft cardinality two distributional word-similarity functions derived from the ukWack corpus. Unfortunately, we combined these measures with other features using regression, obtain- ing positions 18th, 22nd and 23rd among the 90 participants systems in the official rank- ing. Already after the release of the gold stan- dard annotations of the test data, we observed that using only the similarity measures with- out combining them with other features would have obtained positions 6th, 7th and 8th; more- over, an arithmetic average o...
