On a high level of abstraction a Web Information System (WIS) can be described by a storyboard, which in an abstract way specifies who will be using the system, in which way and for which goals. While syntax and semantics of storyboarding has been well explored, its pragmatics has not. A first step towards pragmatics of storyboards is the observation and documentation of life cases in reality. These, however, have to be complemented by user models. This paper presents an approach to capture user models and to specify the various facets of actor profiles that are needed for them. We analyse actor profiles and present a semi-formal way for their documentation. We outline how these profiles can be used to specify actors, which are an important component of a storyboard.
