A computerized system and method are presented that creates implicit content on a mobile device by monitoring and recording input from sensors on the device. Metadata from the implicit content and from user-created content is then analyzed for the purpose of event identification. Using the metadata and event identification, the content is created into clusters, which can be confirmed by the user as actual events. Events can then be grouped according to metadata and event information into a presentation grouping. Users can also be associated with organizations, allowing the sharing of content and event definitions between the organization and its member users. Users can create ad hoc organizations with a particular subset of other users, which simplifies the creation of event meta data and content sharing with other users in the ad hoc organization.
