Introduction: The paper presents original research designed to explore and compare selected aspects of the information seeking behaviour of mathematicians (scientists and students) on the Internet. Method: The data were gathered through a questionnaire distributed at the end of 2011 and in January 2012. Twenty-nine professional mathematicians and…

Discusses how imprecision and uncertainty are dealt with in the UFO (Uncertainty and Fuzziness in an Object-oriented) database model. Such information is expressed by means of possibility distributions, and modeled by means of the proposed concept of "role objects." The role objects model uncertain, tentative information about objects,…

Examines traditional and interactive models that have emerged in information retrieval (IR), and proposes an interactive IR model based on different levels in the interactive processes. Analyzes strengths and weaknesses of the traditional model. Concludes with general remarks on the state of IR interaction research. (Author/AEF)

To generate a search query based on an end-user request, a database searcher has to select appropriate search terms. A selection process is simulated for 94 records of written requests to a psychological information agency and the respective online searches. Results show that the simulation is better than a random selection. (AEF)

The probabilistic retrieval model developed in this paper incorporates the relationships of descriptors. A learning model is proposed to figure out the relationships incrementally. Each time retrieval results are available, the method identifies in the relevant documents the descriptors that designate the concepts specified by the query…

Describes a model of information retrieval as social interaction, which distinguishes between three types of information interaction goals: (1) task-oriented; (2) topically oriented; and (3) those centered around situation assessment (SA). Results suggest that SA is an important cognitive activity in new information retrieval environments; SA…

Discusses issues concerning student research that uses Web-based references, based on the authors' experiences. Describes ways they structured the inquiry process for student research, helped students manage the quantity of information, and provided a model for analyzing the quality of information that students find on Web sites. Includes the…

Describes how reference-based instruction can be incorporated into an instructional system design. Provides specific examples of learning objectives and student exercises. Defines reference-based instruction and outlines its benefits. Lists guidelines for how to structure usability tests for Help systems. Advises how technical communicators can…

Develops and tests a new behavioral model of information seeking on the Web by combining theoretical elements from information science and organization science. Results suggest that a behavioral framework which relates search motivations and moves may be helpful in analyzing Web-based information seeking. (Author/AEF)

This study, based on a survey of 40 library/information science students and observations made from online information retrieval instruction, focuses on information receiving, one of the three primary modes of the Information Process. Compares the modes of the Information Process and examines the role of the World Wide Web. (Author/AEF)
