Episodic memory stores, data ingestion and query systems for same, including examples of autonomous smart agents

A method comprising:

• creating a bitmap table from a plurality of episodes, the plurality of episodes including instances of contextually labeled data, the bitmap table including a designation for a presence or absence of a particular piece of the contextually labeled data in each of the plurality of episodes;
• responsive to a query for the particular piece of the contextually labeled data, accessing the bitmap table;
• and
• reporting the presence or absence of the particular piece of the contextually labeled data from the bitmap table.

A method comprising:

• generate a target signature for particular contextually labeled data in a target semantic context;
• generate a plurality of signatures for other contextually labeled data in the target semantic context;
• calculate a distance between the target signature and each of the plurality of signatures;
• and
• identify selected other contextually labeled data as relevant to the particular contextually labeled data when the corresponding signatures have a distance meeting a predetermined criteria from the target signature.
