Abstract

For the purposes of this article, the indexing of information is interpreted as the pre-processing of information in order to enable its retrieval. The definition thus spans a dimension extending from classification-based approaches (pre-co-ordinate) to keyword searching (post-co-ordinate). In the first section we clarify our use of terminology, by briefly describing a framework for modelling IR systems in terms of sets of objects, relationships and functions. In the following 3 sections, we discuss the application of indexing functions to document collections of 3 specific types: (1) 'conventional' text databases; (2) hypertext databases; and (3) the World Wide Web, globally distributed across the Internet

Abstract

The study explores the role of information and information seeking in the Research and Development Department of an international oil and gas company. The information seeking patterns of engineers and research scientists at Statoil's Research Centre, in Trondheim, Norway were studied in relation to their research activities in different phases and types of project. The project phases were evaluation of alternative solutions; development and testing; and summary of experiences. The project types were incremental; radical; and fundamental. Eight major characteristics were identified in the patterns: surveying; chaining; monitoring; browsing; distinguishing; filtering; extracting and ending. The study analyses the requirements for different types of information in an environment where the need for internal and external resources are intertwined; it also compares features of the information seeking patterns of engineers and research scientists from this and previous studies. It was found that, although there were differences in the features of the information seeking patterns of the research scientists and engineers, the behavioural characteristics were similar; and the study identified identical or very similar categories of information seeking behaviour to those of previous studies of academic researchers.

Abstract

The problem of measurement in information retrieval research is traced to its source in the first retrieval tests. The problem is seen as presenting a chronic dilemma for the field. This dilemma has taken 3 forms as the discipline has evloved: (1) the dilemma of measurement in the archetypal approach: stated relevance versus user relevance; (2) the dilemma of measurement in the probabilistic approach: realism versus formalism; and (3) the dilemma of measurement in the Information Retrieval-Expert System (IR-ES) approach: linear measures of relevance versus logarithmic measures of knowledge. It is argued that the dilemma of measurement has remained intractable even given the different assumptions of the different approaches for 3 connecte reasons - the nature of the subject matter of the field; the nature of relevance jidgement; and the nature of cognition and knowledge. Finally, it is concluded that the original vision of information retrieval research as a discipline founded on quantification proved restricting for its theoretical and methodological development and that increasing recognition of this is reflected in growing interest in qualitative methods in information retrieval research in relation to cognitive, behavioral, and affective aspects of the information retrieval interaction
