Abstract
This paper presents an approach to solving
the problem of textual entailment
recognition and describes the computer
application built to demonstrate the
performance of the proposed approach.
The method presented here is based on
syntax-driven semantic analysis and uses
the notion of atomic proposition as its
main element for entailment recognition.
The idea is to find the entailment relation
in the sentence pairs by comparing the
atomic propositions contained in the text
and hypothesis sentences.
The comparison of atomic propositions is
performed via an automated deduction
system OTTER; the propositions are
extracted from the output of the Link
Parser; and semantic knowledge is taken
from the WordNet database. On its current
stage the system is capable to recognize
basic semantically and syntactically based
entailments and is potentially capable to
use more external and internal knowledge
to deal with more complex entailments.
