Abstract: A method of searching for information includes receiving a query, providing the query to a first search engine that searches a set of data sources, the data sources having relationships to an ontology, receiving search results from the search engine, analyzing the search results to determine at least one statistic corresponding to the search results and the query, wherein the statistic is based upon a relevance score that is calculated based upon a first weighting function related to a concept, a second weighting function related to a data source item, a set of items related to the concept, and a set of items related to the search results, and providing at least one concept to a user, wherein said at least one concept correspond to said at least one statistic.

Abstract: A method and system to process a domain. A domain is modeled with one or more domain models. Support models are generated from domain models. An ontological system utilizes the support models to interact with and manipulate the domain models. Further, the support models are used to describe domain model states.

Abstract: A method, system and machine readable medium are disclosed to process one or more documents in a domain. The method includes modeling the domain with a plurality of domain models using an ontological system; representing each document as a collection of one or more domain models; and populating the domain models that are used to represent the document with values corresponding to properties of the document being represented.

Abstract: According to one aspect of the present invention, a method is provided in which a request is submitted to a first node in a network containing multiple nodes, the request containing data relating to a healthcare event associated with a patient. The request is processed at the first node to obtain information from one or more databases associated with the first node, based upon the data contained in the request. The request is also processed at one or more additional nodes in the network to obtain information from one or more additional databases associated with the one or more additional nodes, based upon the data contained in the request. A response to the request is generated based upon an aggregation of information obtained from the first node and the one or more additional nodes.
