What are the commonalities and differences be-
tween the syntactic and semantic distributional
patterns of the words of a language? This study is
an initial attempt to answer this fundamental and
intriguing ... syntactic class for a long time. There-

confusing than that of the semantic classes – a ... basis of formation of the natu-
ral classes or communities within these networks.
These observations collectively point towards a
well accepted fact that the semantic space of nat-
