A semantic service system may includes a tagging facility for collecting references to resources thereby providing tagged resources; a semantic database for storing the collected references; a semantic associating facility for determining semantic relationships among the references and the resources thereby providing semantic objects; and a user interface for presenting context-based views of one or more of the semantic objects, the references, and the tagged resources. A handheld tagging device includes a computing facility with a camera for acquiring images of resources and a motion sensor for detecting a tagging gesture.
