This paper addresses the problem of acquiring
lexical semantic relationships, applied to
the lexical entailment relation. Our main contribution
is a novel conceptual integration
between the two distinct acquisition paradigms
for lexical relations – the patternbased
and the distributional similarity approaches.
The integrated method exploits
mutual complementary information of the
two approaches to obtain candidate relations
and informative characterizing features.
Then, a small size training set is used to construct
a more accurate supervised classifier,
showing significant increase in both recall
and precision over the original approaches.
