Title: Contextual knowledge based system: A study and design in enology .

Abstract:
Wine making is a domain where formalization is very difficult, mainly because one has to deal with a huge number of heterogeneous pieces of knowledge that intervene at different steps of the wine-making process. We address the problem of stops in the alcoholic fermentation. This step of the wine-making process is strongly correlated with knowledge of the events that occur at previous steps. This knowledge of the previous steps intervenes in the wine-making process as contextual knowledge. In this paper, we present the results of our modeling of contextual knowledge and the design of a context-based system. In our application, we use the onion metaphor to model contextual knowledge. The problem to solve is the heart, and contextual knowledge is organized in layers around the heart in an order that relies on a qualitative distance.
