The Lightcast Occupation Taxonomy (LOT) is an advanced framework developed to classify and organize occupations with high precision and relevance to real-world labor market data. With over 1,800 specialized occupations in its library, it is designed to address the evolving nature of job roles captured from postings and professional profiles.<br /> <br />As we move up in the hierarchy, subsections are exclusive to their associated category. In other words, each specialized occupation is unique to its occupation, each occupation is unique to its occupation group, and each occupation group is unique to its career area. This prevents duplicate or overlapping data when analyzing more than one occupation.<br /> <br />The LOT uses a proprietary classification system of four different levels: career areas, occupation groups, occupations, and specialized occupations.
