摘要
The paper reports experimental results concerning user interaction with document organization, user‐librarian negotiation and the librarian's search processes in public libraries. The focus of the investigations is on the cognitive aspects of information retrieval. After defining the formal framework of the information retrieval (IR) process a theoretical section discusses the cognitive viewpoint on which the research is based, followed by an outline of applicable findings and theories within the fields of cognitive science and cognitive psychology. The experimental design involving tape‐recording and analysis of verbal protocols is briefly described and considered. The main part of the paper concentrates on the results of investigations and considers certain implications. It is shown how the user's knowledge structures cope with the structures of the system. User needs seem often to be presented as a label which may create ambiguity problems. Functions of open and closed questions are investigated and certain behaviouristic factors discussed. Matching the knowledge structure of the user and the librarian is considered a kind of learning process. Librarians prefer search activity before consideration of the presented problem. Without a user present the librarian's IR process is determined by three search attitudes involving motives and expectations as to search routines and possibilities. Conceptual knowledge, previous search and working domain play important roles. The attitudes have consequences for the objectives concerning use of routines and for the use of search concepts.
