Abstract: A system for determining a most probable cause of an event is presented. The system includes a processing subsystem coupled to a smart lighting subsystem and is configured to receive an event signature from the smart lighting subsystem, determine an event based on the event signature, determine an entropy of the event, connect with a plurality of historical data documents, determine information gain of at least a first subset of the plurality of historical data documents, identify and index a plurality of relevant documents from the first subset of the plurality of historical data documents based on the information gain and a determined threshold, determine one or more probable reasons of the event based on the plurality of relevant documents, and determine the most probable cause of the event at least based on the probable reasons, the plurality of relevant documents and the plurality of historical data documents.
