Building Local Knowledge Graphs for OSINT: Bypassing Rate Limits and Maintaining OPSEC

Traditional OSINT collection faces two critical challenges: public APIs throttle queries to prevent abuse, and each query potentially reveals investigative interests to service providers. This talk presents a practical solution using Knowledge Graph technology combined with RDF (Resource Description Framework) to build queryable, offline OSINT repositories.

We demonstrate how to scrape multi-source OSINT data, transform it into RDF format, align it with common ontologies, and store it in local data packages. Once built, analysts can run complex SPARQL queries against their local triplestore without external dependencies or operational security concerns.
