Implementing intelligent agent services includes generating an ontological domain for an individual based upon sets of information elements. A set of the information elements represents aspects of a detectable behavior of the individual at a point in time. The detectable behavior is one of a number of detectable behaviors of the individual occurring within a physical and virtual geography and in relation to time. The detectable behaviors include an activity conducted by the individual at a computer and a presence of the individual at a function. Implementing the intelligent agent services also includes determining relevance of relationships among the sets of the information elements in the ontological domain, and searching sources of information using the sets of the information elements having a relationship determined to be relevant, and identifying a solution for satisfying an interest based on the search.
