Thesaurus-assisted search term selection and query expansion: a review of user-centred studies

This paper provides a review of the literature related to the application of domain-specific thesauri in the search and retrieval process. Focusing on studies which adopt a user-centred approach, the review presents a survey of the methodologies and results from empirical studies undertaken on the use of thesauri as sources of term selection for query formulation and expansion during the search process. It summaries the ways in which domain-specific thesauri from different disciplines have been used by various types of users and how these tools aid users in the selection of search terms. The review consists of two main sections covering, firstly studies on thesaurus-aided search term selection and secondly those dealing with query expansion using thesauri. Both sections are illustrated with case studies that have adopted a user-centred approach

Achieving information fulfilment in the networked society: part 1: introducing new concepts

Purpose – The purpose of this paper is to introduce the idea of information fulfilment. The networked society provides many opportunities for information flow. However, information professionals readily accept that, although one is surrounded by information of many sorts, in many formats, what is important is whether users consider that they ever achieve what is known as “Information Fulfilment”. i.e. occurrences when there has been information which is accurate, timely, current and presented in an appropriate and useful format to allow (work) tasks to be completed. Design/methodology/approach – This first paper contains a literature review which informed the study. The study (which will be reported in detail in a later paper) was interpretive and used ethnography (through participant observation) as the research tool. The research deals with issues surrounding organisation structures and examines levels of information fulfilment in micro substantive settings. Findings – The paper serves to introduce background and cultural information from a small section of a larger European research project which involved five countries and was partially funded by TEMPUS and Leonardo da Vinci Socrates grants. Research limitations/implications – The paper introduces ideas concerning information fulfilment and addresses initial issues concerning a small section of results from a larger project. Phase 2 is now under way and more studies are planned. It is noted that organisation structures are only one variable that affects levels of information fulfilment and there are plans in the future to further extend the study. Originality/value – The research attempts to link the levels of information fulfilment with types of organisation structures. This paper introduces the concept and gives the rationale for the project

Evaluation of a personalized digital library based on cognitive styles: Adaptivity vs. adaptability

Personalization can be addressed by adaptability and adaptivity, which have different advantages and disadvantages. This study investigates how digital library users react to these two techniques. More specifically, we develop a personalized digital library to suit the needs of different cognitive styles based on the findings of our previous work (Frias-Martinez, et al., in press). The personalized digital library includes two versions: adaptive version and adaptable version. The results showed that users not only performed better in the adaptive version, but also they perceived more positively to the adaptive version. In addition, cognitive styles have great effects on users’ responses to adaptability and adaptivity. These results provide guidance for designers to select suitable techniques to develop personalized digital libraries

The exploration of relationships between information fulfilment and organisational design

Purpose: The purpose of this paper is to explore the relationship between information fulfilment and organisational design. Design/ Methodology/Approach: This exploration is undertaken in four ways. First, the early part of the paper places information fulfilment within the literature. Second, there is an attempt to further determine the meaning of Information Fulfilment. Third, the factors that impact on Information Fulfilment are identified within the context of organisational design. Fourth, empirical findings are reported in the form of a European project which investigated the “relationship” between organisational design and information fulfilment. Findings: Information fulfilment is shown to be about the process of taking an intuitive “feel” and delineating a number of aspects which are concerned with what might be called emotion. Fulfilment is also connected with organisational roles and wider environmental issues Originality/ Value: The contribution of this paper to the discipline of information management is that information fulfilment is found to exist and to be an important issue influenced by the design of an organisatio

InfoVis experience enhancement through mediated interaction

Information visualization is an experience in which both the aesthetic representations and interaction are part. Such an experience can be augmented through close consideration of its major components. Interaction is crucial to the experience, yet it has seldom been adequately explored in the field. We claim that direct mediated interaction can augment such an experience. This paper discusses the reasons behind such a claim and proposes a mediated interactive manipulation scheme based on the notion of directness. It also describes the ways in which such a claim will be validated. The Literature Knowledge Domain (LKD) is used as the concrete domain around which the discussions will be held

Search procedures revisited

Search Procedures reflects on a series of studies carried out over a four year period in the late 1970s. It was published at an interesting time for Information Retrieval. Written before Information Retrieval became synonymous with online information seeking it focuses on Information Retrieval within Public Libraries, then the major location for everyday information seeking. While many of his contemporaries focused on information seeking in academic or special library settings, Peter chose instead to focus a setting that was visited by a more diverse set of people with a broader range of information needs

Understanding Novice Users\u27 Help-seeking Behavior in Getting Started with Digital Libraries: Influence of Learning Styles

Users\u27 information needs have to be fulfilled by providing a well-designed system. However, end users usually encounter various problems when interacting with information retrieval (IR) systems and it is even more so for novice users. The most common problem reported from previous research is that novice users do not know how to get started even though most IR systems contain help mechanisms. There is a deep gap between the system\u27s help function and the user\u27s need. In order to fill the gap and provide a better interacting environment, it is necessary to have a clearer picture of the problem and understand what the novice users\u27 behaviors are in using IR systems. The purpose of this study is to identify novice users\u27 help-seeking behaviors while they get started with digital libraries and how their learning styles lead to these behaviors. While a novice user is engaged in the process of interacting with an IR system, he/she may easily encounter problematic situations and require some kind of help in the search process. Novice users need to learn how to use a new IR environment by interacting with help features to fulfill their searching needs. However, many research studies have demonstrated that the existing help systems in IR systems cannot fully satisfy users\u27 needs. In addition to the system side problems, users\u27 characteristics, such as preference in using help, also play major roles in the decision of using system help. When viewing help-seeking as a learning activity, learning style is an influential factor that would lead to different help-seeking behaviors. Learning style deeply influences how students process information in learning activities, including learning performance, learning strategy, and learning preferences. Existing research does not seem to consider learning style and help-seeking together; therefore, the aim of this study is to explore the effects of learning styles on help-seeking interactions in the information seeking and searching environment. The study took place in an academic setting, and recruited 60 participants representing students from different education levels and disciplines. Data were collected by different methods, including pre-questionnaire, cognitive preference questionnaire, think-aloud protocol, transaction log, and interview. Both qualitative and quantitative approaches were employed to analyze data in the study. Qualitative methods were first applied to explore novice users\u27 help-seeking approaches as well as to illustrate how learning styles lead to these approaches. Quantitative methods were followed to test whether or not learning style would affect help-seeking behaviors and approaches. Results of this study highlight two findings. First, this study identifies eight types of help features used by novice users with different learning styles. The quantitative evidence also verifies the effect of learning styles on help-seeking interactions with help features. Based on the foundation of the analysis of help features, the study further identified fifteen help-seeking approaches applied by users with different learning styles in digital libraries. The broad triangulation approach assumed in this study not only enables the illustration of novice users\u27 diversified help-seeking approaches but also explores and confirms the relationships between different dimensions of learning styles and help-seeking behaviors. The results also suggest that the designs and delivery of IR systems, including digital libraries, need to support different learning styles by offering more engaging processing layouts, diversified input formats, as well as easy-to-perceive and easy-to-understand modes of help features
