Abstract:
We design and test a sentence comparison method using the framework of
Robust Minimal Recursion Semantics which allows us to utilise the deep
parse information produced by JACY, a Japanese HPSG based parser and
the lexical information available in our ontology. Our method was used
for both paraphrase detection and also for answer sentence selection for
question answering. In both tasks, results showed an improvement over
Bag-of-Words, as well as providing extra information useful to the
applications.
