Methods and apparatuses for assigning moods to content and searching for moods to select content

摘要

Systems and methods for content identification and search are described. Content is identified or represented by one or more moods conveyed by the content to viewers. Identified moods are assigned range areas corresponding to each mood. Range areas are assigned spans corresponding to the range areas. Assigned spans are digitized and stored for searching. Searches are initiated by users through the identification of one or more moods and corresponding identification spans within ranges corresponding to the ranges. Once a user has selected at least one search span, a search is performed by looking for content having identification spans that at least partially correspond to the selected search spans, with content being ordered or ranked based on the degree of overlap between the identification spans and the search spans.
