A method finds people within a network of people who are interested in the same topic. Individual user profiles, for people within the network of people based upon concepts featured in documents consumed by said people so that the individual user profiles include user-specific concepts, are provided in a database. A document concerning a topic of interest is selected. A computer system creates a model of the selected document including document-specific concepts featured in the selected document. A computer system compares the document-specific concepts to the user-specific concepts from the individual user profiles. Any matches as a result of the comparing step are determined. If there are any matches, at least one match is reported to a user.
