Methods, systems, and computer program products for implementing ontological domain services are provided. A method includes gathering information elements relating to an individual from trusted sources of information via secure channels of communication. The method also includes creating an ontological domain that is specific to the individual using the information elements accrued from the sources. The information elements are acquired from detectable behaviors of the individual over time. The ontological domain is automatically generated from the detectable behaviors and absent any intervention by the individual. The method also includes determining an interest that is specific to the individual based upon relevancy analyses performed with respect to the information elements and making the interest available to the individual or entity.
