Abstract
A hierarchical decoder is operable to decode a hierarchical multi-layer data package. The hierarchical multi-layer data package includes a plurality of layers and one or more subpackages in each layer. To decode the data package, an objective function is created based on parameters for identifying data in the data package most relevant to information of interest. Subpackages in one or more layers are evaluated using the objective function and a subpackage is selected. Information for the selected subpackage, which may include a summary and metadata, is used to determine whether the subpackage satisfies an information need. If the information need is not satisfied, a drill down procedure is performed to evaluate subpackages in a next lower layer of the data package.
