Systems and methods for event stream platforms which enable applications

摘要

Systems and methods to generate a final event stream are provided. The system collects information from a wide variety of sources, and then parses, normalizes, and indexes the information. This generates an initial event stream that can be tagged and then iteratively processed to generate a final event stream. The processing includes first order logic querying and knowledge extraction to infer additional events which is added to the event stream. The final event stream is used by a knowledge exchange for consumption by applications. These applications may be internal applications and/or third party applications. This system may be particularly useful in use with medical information, or any other big data enterprise system.

主权项

1. In a Medical Information Navigation Engine, a computerized method for generating a final event stream, the method comprising:
collecting medical information from a plurality of data sources; parsing the medical information; normalizing the medical information; indexing the medical information to generate an initial event stream, wherein an event includes a fact that is either true or false, occurs in a specific time interval for a specific subject, attributed to a source and episode grouping, and the event stream is a collection of such events; semantic meta-tagging the event stream; and iteratively processing the event stream to generate a final event stream, wherein the processing includes at least one of first order logic querying and knowledge extraction to infer at least one additional event which is added to the event stream by agents to provide a rich and expanded event stream for deriving clinical knowledge and downstream applications.
