The goal of labourR is to map multilingual free-text of occupations, such as a job title in a Curriculum Vitae, to hierarchical ontologies provided by ESCO, the multilingual classification of European Skills, Competences, Qualifications and Occupations, and ISCO, the International Standard Classification of Occupations.

Fig.1 - ESCO is mapped to the 4th level of the ISCO hierarchical model.

Computations are vectorised and the data.table package is used for high performance and memory efficiency.

See Articles section for details.
