Abstract: An information processing apparatus includes a storage unit and a computing unit. The computing unit receives registration of information corresponding to a user and indicating levels of a plurality of skill items. Further, the computing unit receives an input specifying levels of the plurality of skill items, and displays a radar chart including a first graph based on the specified levels. The computing unit executes a search for a user from among users who are registered, using the specified levels as a search condition. The computing unit displays a radar chart including a second graph based on levels of the plurality of skill items corresponding to a user found by the search, in a manner associated with the found user.

Abstract: An information processing apparatus includes a storage unit and a computing unit. The computing unit accepts a registration of trust relationship information indicating a trust relationship between specified users among a plurality of registered users, and stores the trust relationship information in the storage unit. When receiving an instruction to display a relationship between a first user and a second user, the computing unit displays a correlation diagram of trust relationships in a range of trust relationships linked between the first user and the second user, and information indicating a trust relationship registered for trust to the second user, irrespective of the range, in parallel to each other.
