Video programs (media) are analyzed, often using computerized image feature analysis methods. Annotator index descriptors or signatures that are indexes to specific video scenes and items of interest are determined, and these in turn serve as an index to annotator metadata (often third party metadata) associated with these video scenes. The annotator index descriptors and signatures, typically chosen to be free from copyright restrictions, are in turn linked to annotator metadata, and then made available for download on a P2P network. Media viewers can then use processor equipped video devices to select video scenes and areas of interest, determine the corresponding user index, and send this user index over the P2P network to search for index linked annotator metadata. This metadata is then sent back to the user video device over the P2P network. Thus video programs can be enriched with additional content without transmitting any copyrighted video data.

A concept learning module trains video classifiers associated with a stored set of concepts derived from textual metadata of a plurality of videos, the training based on features extracted from training videos. Each of the video classifiers can then be applied to a given video to obtain a score indicating whether or not the video is representative of the concept associated with the classifier. The learning process does not require any concepts to be known a priori, nor does it require a training set of videos having training labels manually applied by human experts. Rather, in one embodiment the learning is based solely upon the content of the videos themselves and on whatever metadata was provided along with the video, e.g., on possibly sparse and/or inaccurate textual metadata specified by a user of a video hosting service who submitted the video.

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.
