Abstract

Purpose - One core element of interactive information retrieval (IIR) experiments is the assignment of search tasks. The purpose of this paper is to provide an analytical review of current practice in developing those search tasks to test, observe or control task complexity and difficulty. Design/methodology/approach - Over 100 prior studies of IIR were examined in terms of how each defined task complexity and/or difficulty (or related concepts) and subsequently interpreted those concepts in the development of the assigned search tasks. Findings - Search task complexity is found to include three dimensions: multiplicity of subtasks or steps, multiplicity of facets, and indeterminability. Search task difficulty is based on an interaction between the search task and the attributes of the searcher or the attributes of the search situation. The paper highlights the anomalies in our use of these two concepts, concluding with suggestions for future methodological research related to search task complexity and difficulty. Originality/value - By analyzing and synthesizing current practices, this paper provides guidance for future experiments in IIR that involve these two constructs.

Abstract

Purpose - The purpose of this paper is to understand the needs of humanists with respect to information and communication technology (ICT) in order to prescribe the design of an e-humanist's workbench. Design/methodology/approach - A web-based survey comprising over 60 questions gathered the following data from 169 humanists: profile of the humanist, use of ICT in teaching, e-texts, text analysis tools, access to and use of primary and secondary sources, and use of collaboration and communication tools. Findings - Humanists conduct varied forms of research and use multiple techniques. They rely on the availability of inexpensive, quality-controlled e-texts for their research. The existence of primary sources in digital form influences the type of research conducted. They are unaware of existing tools for conducting text analyses, but expressed a need for better tools. Search engines have replaced the library catalogue as the key access tool for sources. Research continues to be solitary with little collaboration among scholars. Research limitations/implications - The results are based on a self-selected sample of humanists who responded to a web-based survey. Future research needs to examine the work of the scholar at a more detailed level, preferably through observation and/or interviewing. Practical implications - The findings support a five-part framework that could serve as the basis for the design of an e-humanist's workbench. Originality/value - The paper examines the needs of the humanist, founded on an integration of information science research and humanities computing for a more comprehensive understanding of the humanist at work.

Abstract: Computer-based systems are increasingly used by society for everyday activities. Yet these systems are rarely exploited to meet personal information needs. One development that may change this imbalance is the community online system. This paper examines one type of community online system, the Free-Net, and discusses its usefulness in delivering the information and services typically provided by community information centers

Abstract

We introduce WiIRE, a prototype system for conducting interactive information retrieval (IIR) experiments via the Internet. We conceived Wi IRE to increase validity while streamlining procedures and adding efficiencies to the conduct of IIR experiments. The system incorporates password-controlled access, online questionnaires, study instructions and tutorials, conditional interface assignment, and conditional query assignment as well as provision for data collection. As an initial evaluation, we used WiIRE inhouse to conduct a Web-based IIR experiment using an external search engine with customized search interfaces and the TREC 11 Interactive Track search queries. Our evaluation of the prototype indicated significant cost efficiencies in the conduct of IIR studies, and additionally had some novel findings about the human perspective: about half participants would have preferred some personal contact with the researcher, and participants spent a significantly decreasing amount of time on tasks over the course of a session.

Abstract

This research aimed to gain a detailed understanding of how genealogists and historians interact with, and make use of, finding aids in print and digital form. The study uses the lens of human information interaction to investigate finding aid use. Data were collected through a lab-based study of 32 experienced archives' users who completed two tasks with each of two finding aids. Participants were able to carry out the tasks, but they were somewhat challenged by the structure of the finding aid and employed various techniques to cope. Their patterns of interaction differed by task type and they reported higher rates of satisfaction, ease of use, and clarity for the assessment task than the known-item task. Four common patterns of interaction were identified: top-down, bottom-up, interrogative, and opportunistic. Results show how users interact with findings aids and identify features that support and hinder use. This research examines process and performance in addition to outcomes. Results contribute to the archival science literature and also suggest ways to extend models of human information interaction.

Abstract

Documents belonging to a genre have a definite structure which has evolved within specific discourse communities to the point where its use is fixed and standardized. We speculate that such a structure exhibits a strong visual cue, facilitating document recognition and defining a shape of information. To test the concept of shape, 72 participants from two groups (half currently working in an academic setting and half from the general public) examined 24 documents typically used in the academic environment. The documents were in three versions: one based on form, in which the text was masked, leaving only the layout, a second based on content, in which the document was reduced to its semantic information only, and the full version, the original unaltered document. On examining each of the 24 documents (e.g., journal article, call for papers, annotated bibliography) in one of the three versions, participants identified: the type of document and, its recognizable and/or unfamiliar features. In addition, they assessed 8 print versions of the form document for suggestive features of shape. Two variables were tested: the genre element (form or content) and the participant's membership in the academic community. Not unexpectedly, participants identified more documents in the Full and Content versions than the Form versions. But Form versions were recognized twice as quickly as the other two versions. Thus when document shape was evident, the document was immediately discernible to participants; when participants were required to read the semantic content for a gist of the document and an extrapolation of its contents, it took more time. Surprisingly, discourse community had no effect
