At Indeed We help people get jobs. We improve search relevance by creating occupational and attributes taxonomies that accommodate different international markets. Occupational categories across markets show a great deal of consistency. This allows flexible design in hierarchical structures that fit the needs of a corpus in constant change. But when we consider the simplest elements of jobs: degrees, credentials, skills, etc., we open a window into the normative context of institutions and the regulative practices of labor in different countries. Flexibility here comes at a higher expense, since there’s not always a common semantics. I address the challenge of warrant and its impact in designing taxonomies and ontologies. My aim is to provide some good heuristics that lead, in our case, from those different normative contexts to a more encompassing design.
