Abstract: In one embodiment, a method for determining query return referent data for concept types in a conceptual graph includes generating a conceptual graph for a document query, the conceptual graph comprising a plurality of graph terms, identifying one of more of the plurality of graph terms needing referent data, identifying conceptually similar terms for each of the graph terms, for the graph terms needing referents, identifying referent data by searching for instances where conceptually similar terms for graph terms needing referent data are associated by conceptually similar terms for the linking concept term, and associating identified referent data with the graph terms needing referent data.

Abstract: A turbocharger is provided with a tubular insert that carries engine coolant to an area adjacent the bearing supporting the end of the shaft upon which the turbine wheel is attached to provide cooling so that the temperature of the bearing does not increase to an unacceptable level.

Abstract: A label holder for a product information label is suspended from a wire rod forming part of a wire basket, wire shelf, or the like containing the product, the label holder having elongate tabs along the upper margin which loop around the rod and attach to the body of the holder. The tabs have adhesive inner surfaces which are pressed into engagement with the rod so as to stabilize the label holder against swaying when traversed by a bar code reader.
