Two design principles, which we call incremental diagenesis and incremental summarization, help human editors flexibly distill the informal information. Our system, Arkose, is built as a demonstration of these principles, providing the necessary tools for distillation. These tools include a number of visualization mechanisms (Keyword Farm and Author Network) and information retrieval mechanisms, as well as an authoring tool and a navigator for the information space. They support a gradual increase in the order and reusability of the information space and allow various levels of intermediate states of a distillation. 

Our current implementation of the Arkose system demonstrates that such a system is feasible although complex.
