SFTZJS-KG v1.0: A Provenance-Linked Knowledge Organization Dataset of the Suanfa Tongzong (1592)

<p>SFTZJS-KG is a provenance-linked dataset built from the <em>Suanfa Tongzong</em> (1592), a foundational Chinese arithmetic compendium. It contains 1,177 extraction records across five record types (terms, contextual entities, algorithms, formulas, knowledge points), 2,548 registered entities, and 2,777 relation assertions (2,594 distinct subject–predicate–object statements), serialized as 49,000 RDF triples.</p><p>Every record is linked to its source CSV and row number, and every entity and assertion carries a provenance status and an evidence level. Inferred assertions are marked as candidates and excluded from the materialized graph, so reconstructed knowledge is not presented as attested fact.</p><p>The package includes the extraction tables, three registries (entities, relations, provenance), the Turtle serialization, a 23-class ontology, a data dictionary, three reproducible query examples, validation scripts, and a SHA-256 manifest.</p><p>This is the public variant: it contains no scanned pages, no OCR output, and no editorial annotations from the modern critical edition. Two verbatim quotation columns are omitted (626 rows); all descriptive fields are retained.</p><p>Known limits: 186 extraction records have no mapped relations; 899 assertions are candidates and not materialized; page boundaries for volumes 4–6 contain a known offset. No OWL reasoner validation was performed.</p>
