Over time, researchers have acknowledged the importance of understanding the users’ strategies in the design of search systems. However, when involving users in the comparison of search systems, methodological challenges still exist as researchers are pondering on how to handle the variability that human participants bring to the comparisons. This paper present methods for controlling the complexity of user-centered evaluations of search user interfaces through within subjects designs,...

Information-seeking is important for lawyers, who have access to many dedicated electronic resources. However there is considerable scope for improving the design of these resources to better support information-seeking. One way of informing design is to use information-seeking models as theoretical lenses to analyse users’ behaviour with existing systems. However many models, including those informed by studying lawyers, analyse information-seeking at a high level of abstraction and are...

Information behavior (IB) research involves examining how people look for and use information, often with the sole purpose of gaining insights into the behavior displayed. However, it is also possible to examine IB with the purpose of using the insights gained to design new tools or improve the design of existing tools to support information seeking and use. This approach is advocated by David Ellis who, over two decades ago, presented a model of information seeking behaviors and made...

To help design an environment in which professionals without legal training can make effective use of public sector legal information on planning and the environment - for Add-Wijzer, a European e-government project - we evaluated their perceptions of usefulness and usability. In concurrent think-aloud usability tests, lawyers and non-lawyers carried out information retrieval tasks on a range of online legal databases. We found that non-lawyers reported twice as many difficulties as those...

This paper describes a qualitative study of information-seeking behavior patterns of students at the Villanova University School of Law Farmworker Legal Aid Clinic. The interactions of law student researchers with legal information systems were observed, as well as the overall context of use of those systems. The purpose of this study is to develop a conceptual framework for legal information behavior. A strong conceptual framework can be used by librarians and system designers to develop improved legal information systems, services, and instruction.

Purpose - This paper seeks to report an investigation into the ways in which end-users perceive a thesaurus-enhanced search interface, in particular thesaurus and search interface usability. Design/methodology/approach - Thirty academic users, split between staff and postgraduate students, carrying out real search requests were observed during this study. Users were asked to comment on a range of thesaurus and interface characteristics including: ease of use, ease of learning, ease of...

Previous work on understanding user web search behavior has focused on how people search and what they are searching for, but not why they are searching. In this paper, we describe a framework for understanding the underlying goals of user searches, and our experience in using the framework to manually classify queries from a web search engine. Our analysis suggests that so-called navigational" searches are less prevalent than generally believed while a previously unexplored...

One of the most pressing usability issues in the design of web sites is that of how to improve navigation and search. We are conducting a series of usability studies to address this problem, focusing on web sites that consist of large collections of loosely organized information. This article describes our method and presents preliminary results which suggest that use of faceted metadata can be useful both for the initial stages of highly constrained search and for the intermediate stages of...

The paper examines the information needs and seeking behaviour of lawyers in Lagos, Nigeria. Results reveal that many lawyer is perceived the need to know the latest decisions of superior courts as their greatest professional information need. Other expressed needs include knowing recent legislation, obtaining information on local and international seminars and conferences, and on acquisition and application of legal “know-how”. The library has been identified as the most heavily consulted...

Research on Web searching is at an incipient stage. This aspect provides a unique opportunity to review the current state of research in the field, identify common trends, develop a methodological framework, and define terminology for future Web searching studies. In this article, the results from published studies of Web searching are reviewed to present the current state of research. The analysis of the limited Web searching studies available indicates that research methods and terminology...

The study reported in this paper is part of a programme of ongoing research based on the model of the Information Search Process (ISP) developed in a series of prior studies by Kuhlthau. This study sought to gain a better understanding of the variety of tasks that involve lawyers as a particular group of information workers, how they use information to accomplish their work, and the role mediators play in their process of information seeking and use. Findings revealed that these lawyers...

The information-seeking behavior of lawyers has not been fully investigated empirically. Prior work has tended to focus on legal research as the central task performed by lawyers in their information-seeking activities. This analysis of more than 150 interviews of practicing lawyers showed that legal research should not be considered information-seeking. The lawyers interviewed identified other tasks, such as administration of their law practices, as constituting problem-solving,...

Our research focuses on designing effective search aids for legal researchers interested in law-related information on the world wide web. In this paper we report on the design and evaluation of two software systems developed to explore models for browsing and searching across a user-selected set of WWW sites. A directory services tool, LIBClient, provides a hierarchical index of legal information resources in an interface emphasizing ease-of-use by Internet novices and management of...

The paper presents the results of a pilot study of 15 lawyers at various stages of their career. We examine novice lawyers at the beginning of their career and compare their concepts of task, information and information seeking with the concepts of task, information and information seeking of expert lawyers who have practiced law for more than 7 years. We observed that while novice lawyers have separate problem recognition and solution structures, for expert lawyers these structures are...

In database or knowledge-base systems, query formulation languages are the means offered to users for accessing data or knowledge. Queries allow selection of data under particular, either simple or complex constraints, resulting from one or several structures. However, query formulation remains obstinately difficult for large classes of users. Indeed, with the exception of approaches facilitating syntax problems, there is a noticeable absence of models taking charge of the user through...
