/claim #17

Summary

Implements a self-contained Scientific Knowledge Graph milestone for issue #17.

This adds deterministic linked-data workflows:

• entity extraction for concepts, authors, institutions, tools, datasets, protocols, funders, DOIs, and projects
• typed graph nodes and evidence-backed relationship edges
• entity page payloads with contexts, connected entities, and evidence
• graph search/filtering by type, domain, institution, citation count, and reproducibility
• personalized recommendation payloads for sidebar, weekly digest, and discovery mode
• schema.org/JSON-LD export
• lightweight local API/demo server

Requirement Mapping

• Entity extraction: extractEntities
• Linked data and schema.org metadata: buildJsonLdExport
• Entity pages: buildEntityPage
• Knowledge navigation/search: searchGraph
• Relationship graph: buildKnowledgeGraph
• AI research recommendations: buildRecommendations
• Personalized feed: recommendation scoring uses interests, project history, citations, reproducibility, and institution

Full mapping is in scientific-knowledge-graph/docs/requirement-map.md.

Verification

cd scientific-knowledge-graph
npm run check
npm test
PORT=4331 npm start

Notes

Prepared with OpenAI Codex assistance. The implementation and tests were reviewed and run locally before submission.
