Gianni Anelli’s research article 'But which skills? : Natural Language Processing tools and the identification of high-demand skills in online job advertisements' discusses the relevance of data from online job portals. Using two skills dictionaries, the ESCO dictionary and a national labour market dictionary, this study extracted required skills from Chilean online job advertisements. The study found enhanced results when applying the latter dictionary method and so concludes its incorporation into labour market information systems, and online job portals, would enable better decision making by the various actors in the labour market.
