An “RFID-Based Inference Platform” provides various techniques for using RFID tags in combination with other enterprise sensors to track users and objects, infer their interactions, and provide these inferences for enabling further applications. Specifically, observations are collected from combinations of RFID tag reads and other enterprise sensors including electronic calendars, user presence identifiers, cardkey access logs, computer logins, etc. Given sufficient observations, the RFID-Based Inference Platform automatically differentiates between tags associated with or affixed to people and tags affixed to objects. The RFID-Based Inference Platform then infers additional information including identities of people, ownership of specific objects, the nature of different “zones” in a workspace (e.g., private office versus conference room). These inferences are then used to enable various applications including object tracking, automated object ownership determinations, automated object cataloging, automated misplaced object alerts, video annotations, automated conference room scheduling, semi-automated object image catalogs, object interaction query systems, etc.
