ABSTRACT:
A method and system that aggregates data associated with one or more entities from different data sources are provided. The data sources include documents, web pages, or images that have information about one or more entities. The information is extracted from the data sources based on criteria that define the entities. The extracted information is utilized to generate a hash identifier that corresponds to each entity and one or more storage locations. The one or more storage locations and associated hash identifiers are utilized to store the extracted information corresponding to the entities, and the extracted information for each entity is structured as a virtual page that is stored in an index having references to the data sources. The index storing the virtual pages is notified or updated when the associated data sources are modified.
