Gephi (and other graph tools) aren't quite the same thing. The front-end user interface, and the workflows are different. It's a little closer to how maybe yED works with dragging and dropping of entities, connections, groups, but also a robust meta-data system attached to all of those things + some tools that make bringing in new information from free-text (or wherever) simple. Then all that stuff should be stored in some kind of centralized semantic database that any user using that system can search and find stuff somebody else already put in there. Maybe a document search as well so you can see what raw documents have been ETL'd. Then take various attributes off of some of the entities and relationships (like dates, or geos, or IPs) and builds various ways of looking at, filtering, and search that stuff quickly.
