Abstract: A method, a data aggregation tool, and a set of instructions are disclosed. A data storage 120 may store a data aggregation tree with at least one entry node, a root node, and an initial entry status level for the at least one entry node. A processor 110 may detect an entry node status level change to a resulting entry status level at the at least one entry node. The processor 110 may aggregate a root node score at a root node based on an entry node score for the at least one entry node.

Abstract: A resource coordinating system is provided. The resource coordinating system has an interface module that receives a request from a user and an ontology framework module including a plurality of objects, each object being associated with a respective resource. The resource coordinating system also has a search module that coordinates a retrieval of information from one or more resources based on a search strategy generated in response to the user's request and an output module that generates an output to the user based on the retrieved information wherein, the search strategy selects objects from the ontology framework module based on the user's request and each selected object directs the search module to its associated resource.
