A Web-Based Approach to Measure Skill Mismatches and Skills Profiles for a Developing Country: The Case of Colombia

A recent publication in Colombia Cientifica by Alianza EFI (economia formal y incusivia) https://editorial.urosario.edu.co/pageflip/acceso-abierto/web-based_web.pdf stresses the importance of Labour market Information (LMI) and how with the proper techniques, job portals can be a robust source of labour market information.

Abstract
Several interdisciplinary studies highlight imperfect information as a possible explanation of skill mismatches, which in turn has implications for unemployment and informality rates. Despite information failures and their consequences, countries like Colombia (where informality and unemployment rates are high) lack a proper labour market information system to identify skill mismatches and employer skill requirements. One reason for this absence is the cost of collecting labour market data.
Recently, the potential use of online job portals as a source of labour market information has gained the attention of researchers and policymakers, since these portals can provide quick and relatively low-cost data collection. As such, these portals could be of use for Colombia. However, debates continue about the efficacy of this use, particularly concerning the robustness of the collected data. This book implements a novel mixed-methods approach (such as web scraping, text mining, machine learning, etc.) to investigate to what extent a web-based model of skill mismatches can be developed for Colombia.
