Users as actors in interactive information retrieval (IIR) are seen in the contexts of their perceived work tasks and information seeking behaviour. The paper models IIR processes by demonstrating a variety of approaches, ranging from Ingwersen's cognitive communication model for IR interaction, over Saraceveic' stratified model which includes a typology of relevance conceptions, to Borlund's model of work task perception, information need development and relevance assessments. Other associated models and perspectives of IIR are discussed when appropriate to the major focus points of the contribution: information need development and typology; understanding of relevance in IIR; and experimental problems in IIR.
