  In this paper, we propose Vocab-Expander at https://vocab-expander.com, an
online tool that enables end-users (e.g., technology scouts) to create and
expand a vocabulary of their domain of interest. It utilizes an ensemble of
state-of-the-art word embedding techniques based on web text and ConceptNet, a
common-sense knowledge base, to suggest related terms for already given terms.
The system has an easy-to-use interface that allows users to quickly confirm or
reject term suggestions. Vocab-Expander offers a variety of potential use
cases, such as improving concept-based information retrieval in technology and
innovation management, enhancing communication and collaboration within
organizations or interdisciplinary projects, and creating vocabularies for
specific courses in education.
