Systems and methods are described that may be used for the creation of user defined objects arising from the implicit interaction of a user with a network resource. The objects are made generally available within the network. A network resource in communication with a network maintains content accessible by a plurality of users of the network. An agent provided to a user device identifies an implicit interaction with a portion of the content and transmits information associated with the implicit interaction to another computing system communicatively connected to the network. The information includes a URL identifying the network resource and the portion of the content and is provided in a user-defined object on the network. Frequency of occurrence of a URL in a plurality of the objects can be used to determine relevance of a network resource and its content.
