DESCRIPTION:Recent developments in NLP have enabled language change resear
 ch to use tools that were originally developed to study synchronic similar
 ities between words. We review and report several proposed laws of semanti
 c change that have been found for distributional word representations base
 d on these techniques. Furthermore\, we advocate the use of control condit
 ion under which any proposed laws should be validated. We found that under
  a stringent control condition\, many of the previously reported laws of s
 emantic change diminished significantly\,  or vanished. Specifically\, wor
 d frequency is found to play an artefactual role either directly or indire
 ctly (due to co-linearity) in many of the proposed laws of semantic change
 . We claim that these modified laws are in fact more credible than the ori
 ginal ones due to the diverse factors that are involved in semantic change
 .
