Abstract: A system for managing medical records based on semantic address parsing. The system comprises a processor, a memory, and an application that comprises a semantic address parser that incorporates a graphical discriminative probabilistic model. When executed by the processor the application receives an address as input comprising tokens and for each token identifies a feature value of at least one feature associated with the token. The application analyzes the feature values to determine an address label for each token and based on the address labels of the tokens, converts the input patient address to a canonical address format. The application searches a data store of medical records to find a stored medical record having a patient address that matches the input address in canonical address format and processes a medical record associated with the input patient address based on the matching stored medical record.

Abstract: A search method is provided. The method comprises, building a first plurality of collectors, associating a first plurality of index entries with the first plurality of collectors, wherein each index entry comprises a search target and is associated with at least one of the first plurality of collectors based on a similarity between the search target of the index entry and the at least one collector, selecting a second plurality of collectors from among the first collectors based on a similarity between a search term and each of the second plurality of collectors, selecting a second plurality of index entries from among the index entries associated with the second plurality of collectors based on a similarity between the search term and the search target of each of the index entries associated with the second plurality of collectors, and presenting information related to the second plurality of index entries.
