The power of the Knowledge Graph comes from its Semantic Web structure. The Graph can be imagined as an information network, in which historical data is organized into categories, classes, and relationships. Unlike a conventional database, all data in the Knowledge Graph has a ‘meaning’ that a machine can interpret. In other words, raw information becomes knowledge—and this knowledge can power research and discovery.
To date, the Knowledge Graph contains over 2.9 million linked data ‘triples’—meaningful statements—concerning people, places, offices, and organizations across Irish history.

Datasets
The Knowledge Graph for Irish History draws on curated datasets containing data on people, places, offices, and organizations. Individual people and places mentioned in the Graph are known as ‘entities’. Every entity in the Graph has a unique resource identifier, or URI. The Knowledge Graph is a dynamic resource. As more historical entities are added, the Graph will continue to grow.
Key datasets in the graph include:
- Present Day Places: over 60,000 modern place-names in a hierarchy of all counties, baronies, parishes, and townlands in Ireland generating 2,411,271 triples
- Modern Place: over 2,000 modern place-names in a hierarchy of all counties, baronies, parishes, and townlands in Ireland generating 29,669 triples
- Dictionary of Irish Biography : over 10,000 persons from the Dictionary of Irish Biography generating 514,347 triples
