Dataset
ProMajor Event Taxonomy
A classification taxonomy over material announcements — per row: event class, subject, event time, confidence, and rule version; sourced from MOPS material announcements.
What this data is
Each row is one classified material announcement, carrying event_class / subject / event_time / confidence / rule_version (event class, subject, event time, confidence, and rule version). Sourced from MOPS material announcements, graded reference / master. Keyed on the data as-of date and point-in-time safe; The backend /v2/datasets meta exposes only grade / tier / point-in-time and no coverage window, so none is stated here.
Use cases
- Group material announcements into an analyzable event stream via event_class.
- Filter by confidence for classification reliability.
- Track rule_version for reproducible, versioned classification.
Why it matters for stock analysis
Material announcements are free text; this dataset structures them via a versioned taxonomy with confidence, point-in-time safe.
