What we add

Topic graph

A wire service tags a release with a category, once. It doesn't maintain a durable graph over time. We connect them to a topic graph an agent can query.

Continuous Integration https://decisioninsights.ai/term/continuous-integration-ci/ Continuous Integration and Continuous Deployment https://decisioninsights.ai/term/continuous-integration-and-continuous-deployment-cicd/ Enterprise https://decisioninsights.ai/term/enterprise/ and 2 more

Counted facts

A protocol or open source project keeps no vendor list and publishes no figures of its own to check this against. This counts how it actually shows up across the graph -- articles that name it, the organizations named alongside it in those articles, similar projects, and organizations whose topic tags overlap with its own -- computed, not curated.
