1. A method for incrementally integrating and persisting context over an available observational space, comprising: obtaining a new observation for an entity; using at least one feature associated with the new observation to create at least one index key; using the at least one index key to query one or more reverse lookup tables to identify previously persisted candidates observations from previously persisted observations, wherein each of the one or more reverse lookup tables has an associated index; using a threshold to make a new assertion about how the new observation and a first previously persisted candidate observation are related to the entity based on a number of features of the new observation and the first previously persisted candidate observation matching; using the new observation to review previous assertions to determine that a previous assertion that indicated that two previously persisted candidate observations were one of same and related is to be reversed; in response to reversing the previous assertion, incrementally integrating the new observation, the new assertion, and the reversed assertion into persistent context, wherein the persistent context is represented with assertions that indicate which of the new observation and the previously persisted observations are at least one of same and related; and using the persistent context to make a business decision.
