- Abstract
- The objectives of the study were to conduct a series of observations and experiments under as real-life a situation as possible related to: (i) user context of questions in information retrieval; (ii) the structure and classification of questions; (iii) cognitive traits and decision making of searchers; and (iv) different searches of the same question. The study is presented in three parts: part 1 presents the background of the study and describes the models, measures, methods, procedures and statistical analyses used. Pt.2 is devoted to results related to users, questions, and effectiveness measures, and pt.3 to results related to searchers, searches, and overlap studies. A concluding summary of all results is presented in pt.3

- Abstract
- Reports preliminary results from a study, conducted at Rutgers Univ., School of Communication, Information and Library Studies, to conduct observations and experiments under real-life conditions on the nature, effects and patterns in the discourse between users and intermediary searchers and in the related computer commands in the context of online searching and responses. The study involved videotaping interactions between users and intermediaries and recording the search logs for 40 questions. Users judged the relevance of output and completed a number of other measures. Data is analysed both quantitatively, using standard and innovative statistical techniques, and qualitatively, through a grounded theory approach using microanalytic and observational methods

- Abstract
- Develops a theoretical framework for expressing the nature of feedback as a critical process in interactive information retrieval. Feedback concepts from cybernetics and social sciences perspectives are used to develop a concept of information feedback applicable to information retrieval. Adapts models from human-computer interaction and interactive information retrieval as a framework for studying the manifestations of feedback in information retrieval. Presents results from an empirical study of real-life interactions between users, professional mediators and an information retrieval system computer. Presents data involving 885 feedback loops classified in 5 categories. Presents a connection between the theoretical framework and empirical observations and provides a number of pragmatic and research suggestions

- Abstract
- Examines traditional and interactive models in information retrieval, and proposes an interactive information retrieval model based on different levels in the interactive process. Proposes a stratified interactive information retrieval model which has potential to account for a variety of aspects in the processes involved. In this model information retrieval interaction is decomposed into several levels that subtly affect each other. Makes general remarks on the state of information retrieval interaction research

- Abstract
- Discusses underlying concepts related to value that must be clarified in order to proceed with any pragmatic study of value, and establishes a theory of use-oriented value of information and information services. Examines the notion of value in philosophy and economics and in relation to library and information services as well as the connection between value and relevance. Develops 2 models: one related to use of information and the other to use of library and information services. They are a theoretical framework for pragmatic study of value and a guide for the development of a Derived Taxonomy of Value in Using Library and Information Services

- Abstract
- A recent study begun at Case Western Reserve University and continued at Rutgers University compared the transcripts of 200 DIALOG searches conducted by 36 experienced searchers on real questions submitted by academic and industrial researchers. Relevance judgements by the researchers were used to give recall and precision scores to each search result. Findings included: a low degree of overlap between searches on the same question in selection of search terms or items retrieved; the more often an item was retrieved by different searchers, the more likely it was to be judged relevant; recall and precision were not necessarly inversly related; there was a significant positive impact on recall/precision from using more cycles (a sequence from selecting terms to displaying results); serious uncorrectd errors were a major problem in poor searches and proper selection of terms a key to successful searches.
