Abstract: Systems and methods that present error messages in context of entities to application that issue rich queries, via an error propagation component. Accordingly, errors can be built up along the way (e.g., context/nesting), wherein troubleshooting processes can drill back down to the original cause. Hence, the error messages can be presented in the context of entities, as opposed to the underlying store.

Abstract: A method and system for extracting melodic patterns by first recognizing musical “keywords” or themes. The invention searches for all instances of melodic (intervallic) repetition in a piece (patterns). This process generally uncovers a large number of patterns, many of which are either uninteresting or are only superficially prevalent. Filters reduce the number and/or prevalence of such patterns. Patterns are then rated according to characteristics deemed perceptually significant. The top ranked patterns correspond to important thematic or motivic musical content. The system operates robustly across a broad range of styles, and relies on no metadata on its input, allowing it to independently and efficiently catalog multimedia data.
