User-system interaction is a critical aspect for IR and digital librar
ies as well. Thus, a better understanding and modeling of these proces
ses is of great importance to efforts aimed at making these systems mo
re user responsive. The traditional IR model, with all its strengths,
had a serious weakness: it did not depict the rich and varied interact
ion processes. Thus, several IR interaction models have been proposed.
In 1996 I proposed a stratified model that views the interaction as a
dialogue between participants, user and 'computer' (system) through a
n interface at a surface level; furthermore, each of the participants
are depicted as having different levels or strata. On the user side el
ements involve at least these levels: cognitive, affective, and situat
ional. On the 'computer' side there are at least engineering, processi
ng, and content levels. Interaction is the interplay between various l
evels. This general model is now extended to encompass specific proces
ses or phenomena that play a crucial role in IR interaction: the notio
n of relevance, user modeling, selection of search terms, and feedback
types. Examples from a large study of interaction are used to illustr
ate these extensions. Suggestions for further research are made.
