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 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...

Digital Libraries (DLs) is a recent term used to refer to information systems (IS) and services that provide electronic documents-text files, digital sound, digital video-available in dynamic or archival repositories. Some insist that DLs refer to documentary collections that are accessed via the Internet, while others refer to DLs as any collection of electronic text, sound, or video files used in a shared space. There is much at stake in these debates. If DLs are narrowly defined, then we...

This study investigated the effects of end-user search experience on searching behavior in the use of an online information retrieval system by monitoring the QUICKLAW searches of a group of law students over a 1-year period. Searching behavior was examined in these aspects: Searcher command and feature repertoires (i.e., the set of commands and the set of features such as Boolean operators and truncation used), language usage patterns (command and feature use frequencies, state chains of...

Juris-Data est une des plus importantes banques juridiques de France. Les documents sont indexés par une classification juridique élaborée par JurisData. Des techniques de génie cognitif ont été utilisées pour réaliser une interface intelligente pour la recheche d'information basée sur cette classification. Le but de ce système est d'aider l'utilisateur à trouver le cas juridique le plus proche de celui qui le concerne. Cette approche s'est révélée fructueuse, mais pour la généraliser à...
