|Information retrieval: Theory, experiment, and operational systems|
The paper examines the process of scientific communication resulting from users' expressed needs for information and in particular the formal mechanisms for the storage and retrieval of information in response to queries or requests. Formal indexing or coding schemes, Boolean systems, facet analysis, and associative methods, as well as probabilistic models, are reviewed and information-seeking behaviour is discussed.
