A source-traceable knowledge graph connects companies, products, people, deals, markets, and claims. Every edge retains the sentence or record that supports it. Different traversal views operate on one graph rather than separate datasets.
629 company entities
11 graph lenses
~40k sourced facts
Graph lenses: One universe with bounded relationship filters
| Entry mode | Starting object | Traversal purpose |
|---|---|---|
| Universe | All entities | Observe clusters across relationship types. |
| Entity | One company or product | Follow ownership, competition, and evidence. |
| Audience | One stakeholder class | Find entities serving the same users. |
| Market | One clinical or commercial area | Compare participants and claims. |
Traceability: A graph edge is an evidence claim
entity A → relationship → entity B → source pointer → supporting sentence
- Retain the source pointer on every edge.
- Separate extracted claims from inferred clusters.
- Allow every visible relationship to open its evidence.
- Use lenses as filters, not duplicate graph stores.
Traversal modes: Four entrances to one graph
Provenance key: Source identity joins facts across corpora
The source tag is a join key, not decoration. It links the visible fact to its file and line range. Shared claims can connect companies. External identifiers can extend the trail into PubMed, FDA, and SEC evidence.
node → labeled edge → node → fact identifier → file and line range → source sentence
