The structure and function of occupational coding schemes were described and discussed. Coding schemes included Standard Occupational Classification (SOC), Standard Industrial Classification (SIC), Chemical Abstract Service (CAS), International Classification of Diseases (ICD), Bureau of Census (BOC), and Dictionary of Occupational Titles. Coding schemes were compared with the manner in which health professionals implicitly organize their knowledge. The manner in which work related information was encoded naturally was investigated using a collection of empiric phase associations, and analysis of written information contained in the NIOSHTIC abstract database. Several differences were revealed between traditional coding methods and actual knowledge. Traditional coding schemes for occupational health related factors were structured similarly as hierarchical, exclusive, and exhaustive systems. Each was limited to information of one particular type and thus the relationships implicit in the coding scheme were limited. The natural coding schemes used by occupational health professionals did not share these characteristics but were more akin to semantic network data bases. The authors conclude that the currently used schemes perform relatively poorly in comparison and that attention to their basic design is warranted.
