Abstract:
1. Data processing apparatus for propagative correlation comprising: a memory for storing a raw matrix cross-classifying object identifiers (idlt) and actor identifiers (idUt) and storing evaluation values for objects identified by the object identifiers, wherein the evaluation values are provided by users identified by the actor identifiers; a background module configured to convert the raw matrix into reclassified matrix blocks as a function of a criterion linked to a matrix element in the raw matrix; and a selection manager configured to look up, in response to receiving an input actor identifier, the received input actor identifier in a first table which contains links, each of which the links associating a particular one of the actor identifiers (idUt) with one or more of the reclassified matrix blocks the selection manager being further configured to present information based on contents of the one or more reclassified matrix blocks associated with the input actor identifier (idUt), wherein, the background module includes a cross-classifier for converting the raw matrix into the reclassified matrix blocks based on a criterion that combines a presence metric reflecting whether or not the matrix element is present or absent in the raw matrix, and a value metric reflecting an evaluation value of the matrix element, and wherein, the selection manager provides recommendations concerning objects which are a priori unrelated to objects for which users have made evaluations, based on the reclassified matrix blocks.
