1. A method comprising: receiving, by a computer processor, a set of data entities representing users' physical interactions with tangible real-world entities, wherein the tangible real-world entities include geographical locations and physical objects located at the geographical locations; providing a metadata collector to at least one user, wherein the metadata collector is associated with at least one metadata element; receiving user interaction data generated based on interaction between the at least one user and the metadata collector, wherein the user interaction data identifies at least one data entity of the set of data entities, wherein the at least one data entity is added to at least one user profile associated with the at least one user, and wherein the at least one user profile is created to describe the at least one user; attempting to validate a physical interaction of the user with at least one tangible real-world entity represented by the identified at least one data entity using one or more of the group consisting of: location data of the at least one user; photographs associated with the at least one user; the user interaction data; or any combination thereof, wherein the location data of the at least one user, the photographs associated with the at least one user, or the user interaction data indicate whether the user has been at geographical locations of the at least one tangible real-world entity; in an instance in which the physical interaction is validated, generating an association between the at least one metadata element and the at least one data entity, and the user profile associated with the at least one user; and evaluating the user interaction data and the user profile associated with the at least one user to determine an association weight of the generated association between the at least one metadata element and the at least one data entity added to the user profile associated with the at least one user, wherein the generated association either increases or decreases based on the determined association weight.
