AI dataset on the population of Dutch municipalities
41 dialogues with the CBS rows in context (Dutch municipalities, 2025): the model reads the figure, cites it, or declines.
AI dataset: finding the NACE code of an activity
44 dialogues with an extract of the NACE Rev. 2.1 classification in context: the model gives the code, asks for a detail or declines.
AI dataset on the population of Irish counties
39 dialogues with the CSO rows in context (26 counties, census 2022): the model reads the figure, cites it, or declines.
AI dataset: agent finding the HS customs code with a tool
43 agent traces: call to the nomenclature search tool, then the HS code, a follow-up question or a refusal.
AI dataset: finding the HS customs code of a product
43 dialogues with an extract of the Harmonized System in context: the model gives the HS code, asks for a detail or declines.
AI dataset (DPO): HS customs code without guessing
40 preference pairs: HS code read in the nomenclature and cited, versus a neighbouring or remembered code.
AI dataset on the population of U.S. states
43 dialogues for an AI assistant on U.S. state populations: 2025 estimates, change since 2020, regions (Census Bureau). Cites its source.
AI dataset: agent finding the ESCO occupation with a tool
60 agent traces: call to the ESCO search tool, occupations returned, then occupation and code or a refusal.
AI dataset: finding the ESCO occupation of a job title
60 dialogues with ESCO occupations in context: the model gives the occupation and its code, asks for a detail or declines.
AI dataset (DPO): ESCO occupation without guessing
57 preference pairs: occupation read in the ESCO classification and cited, versus a neighbouring or remembered one.
AI dataset: normalizing US addresses
36 dialogues with U.S. Census geocoder lines in context: normalized address, a follow-up question or a refusal.
