A multi-cloud user interface apparatus facilitates transparent use of multiple Internet-based clouds. A network interface compatibly interacts with the multiple Internet-based clouds, a database management system of information, and a user interface that includes a non-human agent. The database management system pertains to a world model that represents a plurality of entities such as workgroups, products, humans, animals, plants, positions, and assets. The database itself can be configured such that the items of information are partially but not wholly stored on individual ones of each of the multiple Internet-based clouds. The non-human agent can be configured to receive input from a human user and to respond to the input by accessing the database. The nature of the response can be automatically derived as a function of an information relevance measurement that is itself calculated as a function, at least in part, of an entity relationship-based metric.
