Artificial intelligence researchers interested in knowledge and in designing and implementing digitized artifacts for representing or sharing knowledge play a crucial role in the development of a knowledge-based economy. They help answer the question of how the computer devices they develop can be appropriated by the collectives that manage the flow of knowledge and know-how underlying human organizations. A dialogical, constructivist view of interaction processes permits theorizing the role of digital tools, seen as sociotechnical devices that serve both as resources and as sources of communication within our organizations.
