Abstract

Purpose

With the vast amount of multilingual information available online, it becomes increasingly critical for libraries to use various multilingual information access techniques in order to effectively support patrons' online information requests. However, this is still a relatively under‐explored area. This paper aims to study the effectiveness and the adoptability of query expansion and translation enhancement in the context of interactive multilingual information access.

Design/methodology/approach

Relying on an interactive multilingual information access system called ICE‐TEA, the authors conducted a controlled experiment (English‐to‐Chinese translation) involving human subjects to assess the retrieval effectiveness, analyzed the collected search logs to examine users' behavior, and employed pre‐ and post‐questionnaires to obtain users' opinions about the system.

Findings

The results confirm that significant improvement in retrieval effectiveness can be achieved by combining query expansion with translation enhancement (as compared to a case when there is no relevance feedback). However, users' ability to understand, interact with and even perceive the complex process of searches involving the combination of query expansion and translation enhancement may greatly impact the effectiveness of the techniques. The results also confirm that human‐generated queries were short queries, which calls for careful consideration of how longer queries perform in real search because many search engines rely on longer and more complex queries.

Originality/value

This study examines two important relevance feedback techniques in the context of human‐involved multilingual information access. This study is a valuable addition to the information seeking behaviour literature.

Abstract

Purpose

This article aims to examine how the interactions and perceptions of users from a defined domain, i.e. science education, vary across different groups of teachers while retrieving video. Given the prevalence of digital resources in use in education today, it is critical to assess users’ perspectives and experiences for retrieving information across different contexts and individual user groups.

Design/methodology/approach

Interactive search experiments with 28 users were performed. A pre-experiment questionnaire collected the demographic information used to form groups for comparison in the present study. Users attempted six experimenter-developed topics using a prototype video retrieval system; experimental measures were recorded, including all actions, completion rates, errors and durations. Users rated their experiences and levels of satisfaction with different aspect of the system after each search topic. Data analyses included mean comparisons across the different groups.

Findings

A variety of influences emerged from the results, including significant variations among teachers’ interactions, levels of satisfaction and expectations across different groups of users.

Research limitations/implications

Understanding the interactions and perceptions when retrieving digital video provides insights for information professionals on how to better support the needs of different users. If systems are not taking into account users and context, there can be a mismatch between the needs of users and interactive systems, which can lead to low perceptions and further underuse of digital resources.

Originality/value

Although similar influences on digital libraries have been analysed in other contexts, they have not been directly assessed, as they specifically pertain to experiences with and perceptions of video.

Abstract

Purpose

Query expansion and query limitation are two known techniques for assisting users to define efficient queries. The purpose of this article is to examine the effectiveness of the two methods.

Design/methodology/approach

The research entailed an objective and subjective evaluation of the effectiveness of automatic and interactive query expansion and of two query limit options. The evaluation included both lab simulations and large‐scale user studies. The objective aspects were evaluated in lab simulations with experts judging user performance. The subjective analysis was carried out by having the participants evaluate the quality of, and express their satisfaction with, the retrieval process and its results, thus employing perceived‐value analysis.

Findings

The main findings reveal a difference between the perceived and real values of these techniques. While users expressed their satisfaction with interactive query expansion and its performance, the real‐value analysis of their performance did not show any significant difference between the retrieval modes.

Originality/value

The article evaluates the objective and subjective effectiveness of automatic and interactive query expansion and two query limit options.

Abstract

Purpose

The purpose of this paper is to clarify the conceptual issues of information behaviour research by reviewing the approaches to information interaction in the context of information seeking and retrieval (IS&R).

Design/methodology/approach

The study uses the conceptual analysis focussing on four pioneering models for interactive IS&R proposed by Belkin, Ingwersen and Ingwersen and Järvelin.

Findings

A main characteristic of models for information interaction is the tripartite setting identifying information resources accessible through information systems, intermediary/interface and user. Dialogue is a fundamental constituent of information interaction. Early models proposed by Belkin and Ingwersen focussed on the dialogue occurring in user-intermediary interaction, while more recent frameworks developed by Ingwersen and Järvelin devote more attention to dialogue constitutive of user-information system interaction.

Research limitations/implications

As the study focusses on four models developed within the period of 1984-2005, the findings cannot be generalised to depict the phenomena of information interaction as a whole. Further research is needed to model the specific features of information interaction occurring in the networked information environments in particular.

Originality/value

The study pioneers by providing an in-depth analysis of the ways in which pioneering researchers have conceptualised the phenomena of interaction in the context of IS&R. The findings contribute to the elaboration of the conceptual space of information behaviour research.

Abstract

Purpose

This paper aims to describe a study of the queries generated from a user experiment for cross‐language information retrieval (CLIR) from a historic image archive.

Design/methodology/approach

A controlled lab‐based user study was carried out using a prototype Italian‐English image retrieval system. Participants were asked to carry out searches for 16 images provided to them, a known‐item search task. Italian speaking users generated 618 queries for a set of known‐item search tasks. User's interactions with the system were recorded and queries were analysed manually quantitatively and qualitatively. The queries generated by user's interaction with the system were analysed and the results used to suggest recommendations for the future development of cross‐language retrieval systems for digital image libraries.

Findings

Results highlight the diversity in requests for similar visual content and the weaknesses of machine translation for query translation. Through the manual translation of queries the authors show the benefits of using high‐quality translation resources. The results show the individual characteristics of users while performing known‐item searches and the overlap obtained between query terms and structured image captions, highlighting the use of user's search terms for objects within the foreground of an image.

Research limitations/implications

This research looks in depth into one case of interaction and one image repository. Despite this limitation, the discussed results are likely to be valid across other languages and image repositories.

Practical implications

To develop effective systems requires studying user's search behaviours, particularly in digital image libraries.

Originality/value

The growing quantity of digital visual material in digital libraries offers the potential to apply techniques from CLIR to provide cross‐language information access services. The value of this paper is in the provision of empirical evidence to support recommendations for effective cross‐language image retrieval system design.

Abstract

Purpose

The purpose of this paper is to understand how users behave and evaluate how systems with users are essential for interactive information retrieval (IIR) research. User study methodology serves as a primary approach to answering IIR research questions. In addition to designing user study procedures, understanding the limitations of varying study designs and discussing solutions to the limitations is also critical for improving the methods and advancing the knowledge in IIR.

Design/methodology/approach

Given this unresolved gap, we apply the faceted framework developed by Liu and Shah (2019) in systematically reviewing 131 IIR user studies recently published (2016–2021) on multiple IR and information science venues.

Findings

Our study achieve three goals: (1) extracting and synthesizing the reported limitations on multiple aspects of user study (e.g. recruitment, tasks, study procedures, system interfaces, data analysis methods) under associated facets; (2) summarizing the reported solutions to the limitations; (3) clarifying the connections between types of limitations and types of solutions.

Practical implications

The bibliography of user studies can be used by students and junior researchers who are new to user-centered IR studies as references for study design. Our results can facilitate the reflection and improvement on IR research methodology and serve as a checklist for evaluating customized IIR user studies in varying problem spaces.

Originality/value

To our knowledge, this work is the first study that systematically reviews the study limitations and solutions reported by IIR researchers in articles and empirically examines their connections to different study components.

Abstract

Purpose

The purpose of this paper is to report a study of how the test instrument of a simulated work task situation is used in empirical evaluations of interactive information retrieval (IIR) and reported in the research literature. In particular, the author is interested to learn whether the requirements of how to employ simulated work task situations are followed, and whether these requirements call for further highlighting and refinement.

Design/methodology/approach

In order to study how simulated work task situations are used, the research literature in question is identified. This is done partly via citation analysis by use of Web of Science®, and partly by systematic search of online repositories. On this basis, 67 individual publications were identified and they constitute the sample of analysis.

Findings

The analysis reveals a need for clarifications of how to use simulated work task situations in IIR evaluations. In particular, with respect to the design and creation of realistic simulated work task situations. There is a lack of tailoring of the simulated work task situations to the test participants. Likewise, the requirement to include the test participants’ personal information needs is neglected. Further, there is a need to add and emphasise a requirement to depict the used simulated work task situations when reporting the IIR studies.

Research limitations/implications

Insight about the use of simulated work task situations has implications for test design of IIR studies and hence the knowledge base generated on the basis of such studies.

Originality/value

Simulated work task situations are widely used in IIR studies, and the present study is the first comprehensive study of the intended and unintended use of this test instrument since its introduction in the late 1990’s. The paper addresses the need to carefully design and tailor simulated work task situations to suit the test participants in order to obtain the intended authentic and realistic IIR under study.

Abstract

Purpose

The purpose of this paper is to elaborate the picture of strategies for information searching and seeking by reviewing the conceptualizations on this topic in the field of library and information science (LIS).

Design/methodology/approach

The study draws on Henry Mintzberg’s idea of strategy as plan and strategy as pattern in a stream of actions. Conceptual analysis of 57 LIS investigations was conducted to find out how researchers have approached the above aspects in the characterizations of information search and seeking strategies.

Findings

In the conceptualizations of information search and information seeking strategies, the aspect of strategy as plan is explicated most clearly in text-book approaches describing the steps of rational web searching. Most conceptualizations focus on the aspect of strategy as pattern in a stream of actions. This approach places the main emphasis on realized strategies, either deliberate or emergent. Deliberate strategies indicate how information search or information seeking processes were oriented by intentions that existed previously. Emergent strategies indicate how patterns in information seeking and seeking developed in the absence of intentions, or despite them.

Research limitations/implications

The conceptualizations of the shifts in information seeking and searching strategies were excluded from the study. Similarly, conceptualizations of information search or information retrieval tactics were not examined.

Originality/value

The study pioneers by providing an in-depth analysis of the ways in which the key aspects of strategy are conceptualized in the classifications and typologies of information seeking and searching strategies. The findings contribute to the elaboration of the conceptual space of information behaviour research.
