The Philosophers SPARQL Explorer is a FAIR-compliant research dataset and exploration platform dedicated to the intellectual heritage of two ancient civilisations. It covers city-states, schools, lineages, and cross-cultural influences whose ideas shaped the trajectory of philosophical thought across the Mediterranean and East Asia.

The project applies semantic enrichment to model philosophers as complex historical entities — articulating birthplaces, master-pupil relationships, school memberships, and patterns of influence. The resulting RDF Knowledge Graph enables advanced querying and reuse, offering a powerful resource for scholars in digital humanities, ancient history, and comparative philosophy.

The dataset adheres to the FAIR data principles — Findable, Accessible, Interoperable, and Reusable — ensuring that its resources are openly published with persistent identifiers, rich metadata, and standardised vocabularies. Geographic entities align with Pleiades coordinates, embedding the corpus within the broader Semantic Web of cultural heritage.

What’s Inside?

The ontology captures a comprehensive network of philosophical history spanning two profound traditions:

• Biographical data — birthplaces, deathplaces, and chronological timelines (century of living, birth and death dates).
• Intellectual lineages — master-pupil relationships and broader philosophical influences (e.g., who influenced Plato; who did Confucius teach).
• Schools of thought — membership and prominent representatives of major movements, from the Platonic Academy and Stoicism to Confucianism and Daoism.
• Geographic data — ancient cities annotated with Pleiades coordinates for spatial analysis.

How to use this tool

This explorer offers a direct path into the data:

1. Direct SPARQL execution — the query editor provides full SPARQL 1.1 access to the embedded RDF graph using an in-browser Comunica engine. No backend required.
2. Visual exploration — browse the dataset through the interactive Atlas, the Knowledge Graph, the curated Example Queries, and the full Ontology Browser.
