The current study details the development of an undergraduate business analytics course that combines components of both active and experiential learning. The course offering is designed to expose students from different backgrounds to an intermediate-to-advanced level of business analytics. The course is unique in that it was designed to be…

This article introduces the CELI corpus, a new learner corpus of written Italian consisting of ca. 600,000 tokens, evenly distributed among CEFR (Common European Framework of Reference for Languages) proficiency levels B1, B2, C1 and C2. The collected texts derive from the language certification exams administered by the University for Foreigners…

The intellectual origins of information organization (IO) as a field of study are examined by tracing the use of the terms, "information organization", "knowledge organization", "bibliographic control", and their variants, and by surveying the educational texts dealing with the various component activities of IO,…

Recently considerable attention has been given in the online information retrieval literature to techniques for producing a weighted output of documents in response to a request. One approach tries to maintain the form of and relationships among requests as they appear in current Boolean logic-based systems, while extending it to permit a weighted…

Explores the theory of psychological relevance and its relationship to information retrieval, and provides an extended example. Topics discussed include information need, the search process, the nature of information, topical relevance, relevance judgments and retrieval testing, information retrieval and bibliometrics, and suggestions for further…

Provides an overview of some of the main ideas in the philosophy of language that have relevance to the issues of information retrieval, focusing on the description of the intellectual content. Highlights include retrieval problems; recall and precision; words and meanings; context; externalism and the philosophy of language; and scaffolding and…

Introduces navigation as a central concept for information retrieval and for information systems in general. The evolution of information systems is described; navigability as an aid to improve relevance is discussed; and a system under development that attempts to facilitate navigation for information retrieval is described. (31 references) (LRW)

Discusses precision and recall in information science and proposes a new model based on fractal geometry for clusters of relevant documents. Search strategies for retrieving a group of relevant documents are reviewed; fractal sets and chaotic processes are described; and the new model is explained. (Contains 43 references.) (LRW)

Discusses general issues of computer and human understanding; contrasts three paradigms of information retrieval methodology, including statistical, deep semantic or natural language, and smart Boolean; describes CONIT, a knowledge-based intermediary retrieval assistance system; and examines system evaluation procedures, including a…

Describes prototype retrieval systems that use statistically based rank retrieval of records for text retrieval and bibliographic records: (1) the PRISE System at the National Institute of Standards and Technology; (2) the CITE System, for MEDLINE; (3) the Muscat System at the Scott Polar Research Institute; and (4) the News Retrieval Tool at the…

Discusses relevance and its role in evaluating the effectiveness of information retrieval. Highlights include an information retrieval interaction model; a review of research; evaluation and measurement, including recall and precision and utility and user satisfaction; judges and judgment conditions; user criteria; decision making; and cognitive…

Discussion of relevance provides an overview to this special issue on relevance research. Topics addressed include user-centered criteria that affect relevance judgments; information-seeking behavior; the need for appropriate research methodologies; models for system design and evaluation; and approaches to facilitate further research, including…

Explores current research on indexing and ranking as retrieval functions of search engines on the Web. Highlights include measuring search engine stability; evaluation of Web indexing and retrieval; Web crawlers; hyperlinks for indexing and ranking; ranking for metasearch; document structure; citation indexing; relevance; query evaluation;…

Discusses the need to develop the concept of user-based relevance for the benefit of users and for the meaningful development of future research in information retrieval. Characteristics of users' criteria of relevance are examined; and research methodology models are considered, including naturalistic inquiry versus scientific, or rationalistic,…

Presents a background on theory in knowledge organization, which has moved from an epistemic stance of pragmatism and rationalism (based on observation of the construction of retrieval tools), to empiricism (based on the results of empirical research). Discusses historicism, external validity, classification, user-interface design, and…
