  We present SetExpander, a corpus-based system for expanding a seed set of
terms into amore complete set of terms that belong to the same semantic class.
SetExpander implements an iterative end-to-end workflow. It enables users to
easily select a seed set of terms, expand it, view the expanded set, validate
it, re-expand the validated set and store it, thus simplifying the extraction
of domain-specific fine-grained semantic classes.SetExpander has been used
successfully in real-life use cases including integration into an automated
recruitment system and an issues and defects resolution system. A video demo of
SetExpander is available at
