摘要：Lexical-semantic resources are used extensively
for applied semantic inference,
yet a clear quantitative picture of their
current utility and limitations is largely
missing. We propose system- and
application-independent evaluation and
analysis methodologies for resources’ performance,
and systematically apply them
to seven prominent resources. Our findings
identify the currently limited recall of
available resources, and indicate the potential
to improve performance by examining
non-standard relation types and by
distilling the output of distributional methods.
Further, our results stress the need
to include auxiliary information regarding
the lexical and logical contexts in which
a lexical inference is valid, as well as its
prior validity likelihood.
