Abstract: Systems and method are provided for extracting and processing terms referenced in multimedia content with the use of different term extraction models to determine the relevance of categories to the referenced terms and to rank the categories by relative dominance for the multimedia content. The most dominant category for the multimedia content and/or particular segment(s) of the multimedia content can then be identified and used to link to supplemental content and/or to identify multimedia content related to topics of interest.

Abstract: A computing system is configured to provide access to electronic content. The computing system includes a processor, a data store, an access control system, and a user interface component. The data store is coupled to the processor and is configured to store the electronic content. The access control system control system is configured to selectively allow a requestor to access the electronic content based on a stored metadata setting that is associated with the link. The user interface component is configured to receive a setting change related to a share associated with the link and to persist metadata associated with the setting change.
