Abstract
Taxonomies provide a structured representation of semantic relations between lexical terms, acting as the backbone of many applications. This is the case of the online labour market, as the growing use of Online Job Vacancies (OJVs) enables the understanding of how the demand for new professions and skills changes in near-real-time. Therefore, OJVs represent a rich source of information to reshape and keep labour market taxonomies updated to fit the market expectations better. However, manually updating taxonomies is time-consuming and error-prone. This inspired NEO, a Web-based tool for automatically enriching the standard occupation and skill taxonomy (ESCO) with new occupation terms extracted from OJVs. NEO - which can be applied to any domain - is framed within the research activity of an EU grant collecting and classifying OJVs over all 27+1 EU Countries. As a contribution, NEO (i) proposes a metric that allows one to measure the pairwise semantic similarity between words in a tax...
