Values in this tab are predicted labels, not observations. Eloundou et al. (2023) published two rating regimes — human raters and GPT-4 — and the β shown here is derived from the GPT-4 rater basis alone; the same task can take a different value under the other regime. The unit and the meaning differ from the observed shares (%) in the other tabs, so do not place them on the same axis.

ESCO occupational vocabulary

Each entry below is matched to this occupation in the published ESCO-O*NET Crosswalk (version 1, 2022). The match types are that crosswalk's; the wording is AI Changing Work's.

  • biomedical scientistESCO 3212.1Same scope

    Biomedical scientists perform all laboratory methods required as part of medical examination, treatment and research activities, particularly clinical-chemical, haematological, immuno-haematological, histological, cytological, microbiological, parasitological, mycological, serological and radiological tests. They perform analytical sample testing and report the results to the medical staff for further diagnosis. Biomedical Scientists may apply these methods in particular in the infection, blood or cellular sciences.

  • bacteriology technicianESCO 3141.2.1This occupation is broader

    Bacteriology technicians provide technical assistance in researching and testing bacteria using laboratory equipment. They collect and analyse data for experiments, compile reports and maintain laboratory stock.

  • cytology screenerESCO 3212.1.2This occupation is broader

    Cytology screeners examine under a microscope samples of human cells obtained from various body parts such as the female reproductive tract, the lung or gastrointestinal tract, assist in identifying cell abnormality and disease such as cancer or infectious agents under supervision, following the orders of the doctor of medicine.The abnormal cells are being transferred to the pathologist for medical diagnosis.
