Abstract:

Method, storage medium and apparatus associated with content preparation and/or selection are disclosed herewith. In embodiments, an apparatus may include a content preparation or selection module to receive, as part of a content preparation or selection, a representation of a concept; and determine, for the content preparation or selection, topical relevance of a content item (N) of a content hierarchy to the concept. The content hierarchy may include a plurality of content items, including N, and determining the topical relevance of N to the concept includes determination of propagation of influence among content items of the content hierarchy subject to constraints that bound the number of operations performed by the computing system to determine the propagation of influence among content items of the content hierarchy with a chosen constant. Other embodiments may be disclosed and/or claimed.
