About MLchart

MLchart is a dataset catalogue for research groups, trading firms and machine learning teams.

The catalogue is organised in domains: terminology and definitions, patents and designs, finance, life sciences and health, science and engineering, commerce, government and law, conversation and social. Each dataset has an identifier (MLC-0101 and onward), a datasheet, a schema and sample records.

Two collections are online in full, one page per record: terminology (72,741 terms in 15 fields) and patents full text (5,000 publications). The remaining datasets show sample records on their datasheet pages and are delivered on request.

Datasets ship as JSONL, CSV or Parquet under a commercial licence, versioned by release (current version 2026.10).
