EPIE Dataset: A Corpus For Possible Idiomatic Expressions
Idiomatic expressions have always been a bottleneck for language
comprehension and natural language understanding, specifically for tasks like
Machine Translation(MT). MT systems predominantly produce literal translations
of idiomatic expressions as they do not exhibit generic and linguistically
deterministic patterns which can be exploited for comprehension of the
non-compositional meaning of the expressions. These expressions occur in
parallel corpora used for training, but due to the comparatively high
occurrences of the constituent words of idiomatic expressions in literal
context, the idiomatic meaning gets overpowered by the compositional meaning of
the expression. State of the art Metaphor Detection Systems are able to detect
non-compositional usage at word level but miss out on idiosyncratic phrasal
idiomatic expressions. This creates a dire need for a dataset with a wider
coverage and higher occurrence of commonly occurring idiomatic expressions, the
spans of which can be used for Metaphor Detection. With this in mind, we
present our English Possible Idiomatic Expressions(EPIE) corpus containing
25206 sentences labelled with lexical instances of 717 idiomatic expressions.
These spans also cover literal usages for the given set of idiomatic
expressions. We also present the utility of our dataset by using it to train a
sequence labelling module and testing on three independent datasets with high
accuracy, precision and recall scores
