DHFI-C Knowledge Graph and Supporting Materials (Version 1.0)

The DHFI-C Knowledge Graph and Supporting Materials provide an ontology-guided RDF dataset for mechanism-based and condition-inclusive drug–herb–food interaction modeling. This record contains both the semantic knowledge graph and the supporting curation materials used during dataset construction. File contents: • dhfi_schema_v1.ttl — Ontology schema defining DHFI-C classes, properties, and semantic relations. • dhfi_triples_v1.ttl — RDF instance data representing curated drug–herb–food interaction statements and mechanistic context. • dhfi_source_curation_master_v1.xlsx — Structured source-level abstraction tables used for entity normalization, interaction definition, and ontology alignment prior to ETL transformation. • dhfi_reference_curation_table_v1.docx — Bibliographic records and curated primary studies (n = 20) supporting the interaction modeling framework. • README.md — Dataset documentation and loading instructions. Additional file included in this version: • PRISMA_2020_checklist_DHFI-C.pdf Completed PRISMA 2020 checklist describing literature search and study selection workflow for the DHFI-C study. • DHFI-C_external_case_based_assessment_v1.xlsxThe external case-based assessment of DHFI-C outputs across four interaction domains. The dataset supports transparency, reproducibility, and FAIR-aligned biomedical knowledge representation.
