  • uploading, by an owning entity, a file to a file sharing environment including, a security label and a keyword associated with the file;

    specifying a first tier of a mandatory access control policy to the file based on the security label, the mandatory access control policy limiting sharing scope of the file and placing a restriction on an ability of the owning entity to share the file within the file sharing environment including limiting an ability to grant a second entity outside the restricted maximum sharing scope access to the file;

    generating a profile for an entity contact and storing the generated profile in memory, the profile including a collaboration vector comprising keywords representing collaboration topics between the owning entity and the entity contact, the keywords associated with a calculated weight;

    calculating a contact score for each entity contact defining relevance matching between the file and the entity contact, the contact score calculated based upon the weight of each keyword in the profile of the entity contact and the keywords associated with the file;

    interactively recommending a first entity contact within the limited sharing scope of the file to the owning entity as a candidate for file sharing based upon an associated contact score of the first entity contact;

    periodically updating the profile of each entity contact and the collaboration vector of each entity contact using new collaboration information; and

    interactively adjusting the recommendation for file sharing based on the updated contact profile, wherein the interactive adjustment includes an automated evaluation within the limited sharing scope of the file.
