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 職業語彙
以下の各項目は、公開されているESCO-O*NET Crosswalk（バージョン1、2022年）で、この職業と一つずつ対応付けられたものです。対応の種類はそのクロスウォークによるもので、表現はAI Changing Workによるものです。
- hydrologistESCO 2114.1.5範囲が同じ
Hydrologists research and study the quality, current challenges, and distribution of water in the Earth. They study water supply from rivers, streams, and springs to determine their adequate and sustainable use. Together with a cross functional team of professionals, they plan and develop how water can be supplied to cities and urban areas while ensuring efficiency and resource conservation.
- hydrogeologistESCO 2114.1.4この職業のほうが広い
Hydrogeologists in mining study the distribution, quality and flow of water in order to keep mine workings free of nuisance water and to ensure an adequate supply of process water. They supply and evaluate information which will protect ground and surface water from contamination.
- environmental geologistESCO 2114.1.1重なるが同じではない
Environmental geologists study how mineral operations may impact the composition and physical characteristics of the earth and its resources. They provide advice on issues such as land reclamation and environmental pollution.
- geologistESCO 2114.1重なるが同じではない
Geologists research the materials that form the earth. Their observations depend on the purpose of the research. Depending on their specialisation, geologists study how the Earth has been shaped over time, its geological layers, the quality of minerals for mining purposes, earthquakes and volcanic activity for private services, and similar phenomena.
- soil scientistESCO 2133.11重なるが同じではない
Soil scientists research and study the scientific discipline concerning soil. They advise on how to improve soil quality to support nature, food production or human infrastructure using surveying techniques, irrigation techniques and erosion reduction measures. They make sure to conserve and restore land suffering from intense farming or human interaction.
- water engineerESCO 2142.1.11重なるが同じではない
Water engineers research and develop methods for the provision of clean water, water treatment and flood damage prevention and reaction. They research water needs in a location and develop methods for meeting those needs, such as designing and developing projects for managing water resources such as treatment plants, pipelines, pump systems, irrigation or draining systems and other water supply systems. Water engineers also ensure proper installation of these systems on construction sites. Water engineers also maintain, repair and build structures that control water resources, such as bridges, canals and dams.
