Saracevic antager at den primære intention i alle IR processer drejer sig om relevans. De<br />
forskellige elementer og lag har alle en consideration af relevans, så Stratified Model<br />
bliver et ”system af relevanser”.<br />
De forskellige lag kan diskuteres med henblik på at bidrage til analysemodellen. Det er<br />
interessant at se på hele processen som indeholdende et element af relevans.<br />
