    Abstract
    A new search paradigm, in which the primary user activity is the guided exploration of a complex information space rather than the retrieval of items based on precise specifications, is proposed. The author claims that this paradigm is the norm in most practical applications, and that solutions based on traditional search methods are not effective in this context. He then presents a solution based on dynamic taxonomies, a knowledge management model that effectively guides users to reach their goal while giving them total freedom in exploring the information base. Applications, benefits, and current research are discussed.

    Abstract
    User interfaces of Web search engines reflect attributes of the underlying tools used to create them, rather than what we know about how people look for information. In this article, the author examines several characteristics of user search behavior: the variety of information-seeking goals, the cultural and situational context of search, and the iterative nature of the search task. An analysis of these characteristics suggests ways that interfaces can be redesigned to make searching more effective for users.

    Abstract
    Progress in search interfaces requires vigorous inquiry into how search features can be embedded into application environments such as those for decision-making, personal information collecting, and designing. Progress can be made by focusing on mid-level descriptions of how search components can draw upon and update workspace content and structure. The immediate goal is to advance our understanding of how to shape and exploit context in search. The long-term goal is to develop an interdisciplinary design resource that enables stakeholders in the computing, social, and information sciences to more richly impact each others' work.

    Abstract
    The Online Public Access Catalog (OPAC) is an information retrieval system characterized by short bibliographic records, mainly of books, journals, and audiovisual materials available in a particular library. This, coupled with a Boolean search interface and a heterogeneous user population with diverse needs, presents special problems for subject searching by end users. To perform effective subject searching in the OPAC system requires a wide range of knowledge and skills. Various approaches to improving the OPAC design for subject searching have been proposed and are reviewed in this entry. The trend toward Web-based OPAC interfaces and the developments in Internet and digital library technologies present fresh opportunities for enhancing the effectiveness of the OPAC system for subject searching.

    Abstract
    Domain visualization is one of the new research fronts resulted from the proliferation of information visualization, aiming to reveal the essence of a knowledge domain. Information visualization plays an integral role in modeling and representing intellectual structures associated with scientific disciplines. In this article, the domain of computer graphics is visualized based on author cocitation patterns derived from an 18-year span of the prestigious IEEE Computer Graphics and Applications (1982-1999). This domain visualization utilizes a series of visualization and animation techniques, including author cocitation maps, citation time lines, animation of a highdimensional specialty space, and institutional profiles. This approach not only augments traditional domain analysis and the understanding of scientific disciplines, but also produces a persistent and shared knowledge space for researchers to keep track the development of knowledge more effectively. The results of the domain visualization are discussed and triangulated in a broader context of the computer graphics field

    Abstract
    The authors describe a set of best practices that were developed to assist in the design of search user interfaces. Search user interfaces represent a challenging design domain because novices who have no desire to learn the mechanics of search engine architecture or algorithms often use them. These can lead to frustration and task failure when it is not addressed by the user interface. The best practices are organized into five domains: the corpus, search algorithms, user and task context, the search interface, and mobility. In each section the authors present an introduction to the design challenges related to the domain and a set of best practices for creating a user interface that facilitates effective use by a broad population of users and tasks.

    Abstract
    The Internet is a medium for education, entertainment, communication, and personal expression. User behavior has developed three main modalities for using this medium effectively - searching, browsing, and monitoring - which are supported to different degrees by conventional tools. Understanding the nature of the interaction allows us to design and implement a system called Mitsukeru to support browsing behaviors, while retaining the free-form movements between other interaction styles. The system uses agent-based modeling and look-ahead to provide informative yet nonintrusive guidance to the user, and is described in detail.

    Abstract
    Adaptive interfaces have received much criticism because adaptation and automatic assistance generally contradict the principles of direct-manipulation interfaces. In addition, their success depends highly on the ability of user models to capture the goals and needs of the users. As the construction of user models is often based on poor evidence, even the most advanced learning algorithms may fail to infer accurately the user goals. Previous research has put little emphasis on investigating usability problems of adaptive systems and developing interaction techniques that could resolve these problems. This paper examines these problems and presents an interaction model for adaptive hypermedia (AH) that merges adaptive support and direct manipulation. This approach is built upon a new content adaptation technique that derives from fisheye views. This adaptation technique supports incremental and continuous adjustments of the adaptive views of hypermedia documents and balances between focus and context. By combining this technique with visual representations and controllers of user models, we form a twofold interaction model that enables users to move quickly between adaptation and direct control. Two preliminary user studies exhibit the strengths of our proposed interaction model and adaptation technique. Future extensions to our work are outlined based on the weaknesses and limitations that the studies revealed.

    Abstract
    The effect that content and layout of bibliographic displays had on the ability of end-users to process catalog information was tested using a 2 x 2 factorial experimental design. Participants were asked to perform two related tasks during the course of the experiment. In the first task, they were asked to select a set of items that they would examine further for a hypothetical paper they must write, using a simulated online catalog to make their assessments of relevance. In the second task, they were asked to examine 20 bibliographic records, decide whether they would choose to examine these items further on the shelf, and identify the data elements that they used to formulate their relevance decision. One group viewed bibliographic records on an interface similar to current online catalogs, one that used data labels and contained data elements commonly found. A second group viewed these records on an interface in which the labels had been removed, but the data elements were the same as those in the first. The third group viewed these records on a labeled display that included enhanced data elements on the brief record display. The final group viewed these records with the same brief record data elements as the third group, but with the labels removed, using ISBD and AACR2 punctuation standards. For the first task, participants using enhanced brief screen interfaces viewed more brief screens and fewer full screens than their counterparts. Screen durations for the second 10 screens were found to have dropped from those of the first 10 screens. Statistical analyses comparing demographic variables to the screen frequencies uncovered many significant differences. Participants using the enhanced-content interfaces made fewer selections from index and full screens, and more selections from brief screens. For the second task, participants who used enhanced-content interfaces were able to make some sort of relevance judgment more frequently than those who used standard-content interfaces.

    Abstract
    This study explores an image-based retrieval interface for drug information, focusing on usability for a specific population - seniors. Qualitative, task-based interviews examined participants' health information behaviors and documented search strategies using an existing database (www.drugs.com) and a new prototype that uses similarity-based clustering of pill images for retrieval. Twelve participants (aged 65 and older), reflecting a diversity of backgrounds and experience with Web-based resources, located pill information using the interfaces and discussed navigational and other search preferences. Findings point to design features (e.g., image enlargement) that meet seniors' needs in the context of other health-related information-seeking strategies (e.g., contacting pharmacists).

    Abstract
    Recording search histories, presenting them to the searcher, and building additional interface tools on them offer many opportunities for supporting user tasks in information seeking and use. This study investigated the use of search history information in legal information seeking. Qualitative methods were used to explore how attorneys and law librarians used their memory and external memory aids while searching for information and in transferring to information use. Based on the findings, interface design recommendations were made for information systems. Results of the study from the legal user group presented evidence of the usefulness of search histories and history-based interface tools. Both user manifestations and researcher observations revealed that searchers need historical information in information seeking. Search histories were found to be useful in many user tasks: memory support, search system use, information seeking, information use, task management, task integration, and collaboration. Integrating information across various user tasks and collaborating with others are extensions of traditional information-seeking and use models. These findings encouraged the design of user interface tools and guidelines building on search history information.

    Abstract
    A natural language interface to an expert system is a program that enables the user to communicate with the system in English or some other human language. It is designed to spare the user from learning some special programming language or command input language. Today this input is almost always typed at a keyboard or assembled with a mouse. Only a few research systems understand spoken input and produce spoken output. The precise definition of an expert system is a matter of argument. For the purposes of this article an expert system is a computer system that is capable of providing expert advice or otherwise performing at an expert level, usually in a rather narrow area. An excellent discussion of the controversy surrounding this term is given in Ref. 1. A typical expert system has at least three different kinds of interfaces. Some have four. One interface is designed to understand user queries and commands, another to generate answers and explanations. The knowledge-engineering interface provides a way for a human expert to endow the system with the expertise it needs to function. This may be a natural language interface as well. Some expert systems also produce documents, such as medical case reports or legal wills or petitions for divorce. The first paradigm expert system, Shortliffe's MYCIN system (2), provided natural language interfaces for both the end user and the engineer. The first widely used expert system that Shortliffe developed, ONCOCIN (3, 4), not only provided natural language interfaces for the end user and the knowledge engineer, it also generated the lengthy patient reports required by complex drug trials. In this article we will concentrate mainly an the natural language understanding and generation required to communicate with the end user, but we will also discuss interfaces for the knowledge engineer. We will describe some document generation techniques briefly.
    The explanation facility, the ability to display its reasoning to the user, has been a key component of the expert system from the very beginning. Even though this facility may not be used very often, its presence gives users some crucial reassurance that they can explore the system's decision-making processes and themselves make a reasoned decision about whether or not to accept the advice given by the system. Elaine Rich (S) was the first to enunciate a fundamental principle of explanation generation in expert systems: It is essential that the explanation generated be derived from the actual decision-making process used by the system so that as that process changes, the explanations change with it. If the system relies an previously stored "canned explanations," then changes in the rules or the inference processes will leave the system providing explanations that are no longer valid. She argues also that the system can give deeper explanations if it operates off the internal reasoning process. From the very beginning, expert systems were thought of as vehicles for learning, particularly through the text that the system provides to explain its reasoning. When William Clancey (6) set out to produce a tutoring system based an the MYCIN system, people thought that this was going to be a quick and easy thesis, but Clancey soon realized that MYCIN's rules, written by experts for other practicing physicians, were not an appropriate way to teach diagnosis to medical students. He spent 10 years building and rebuilding the NEOMYCIN/GUIDON system as an effective tutoring system for medical students. Because of the historic connection between expert sytems and tutoring systems, we add a discussion of natural language interfaces for tutoring systems at the end of this article. Dialogue issues are becoming important as hardware systems speed up and software systems become sophisticated enough to carry an an actual dialogue with the user. This is particularly true in tutoring systems that teach languages. We will conclude with a brief mention of some systems of the future that are still in the research stage.

    Abstract
    Over the last couple of years, there has been a surge of activity in the library automation arena directed toward improved user interfaces. As Breeding looks at the events and activities that have transpired over the last year or so, Breeding sees an incredible amount of progress in creating interfaces that help librarians compete better in an ever more crowded landscape of information providers. It's strategically important for libraries to have technologies in place that will optimize delivery of content and services in the context of today's Web. Breeding believes that failure to make progress in this area can foster a creep of irrelevancy as potential users increasingly rely on information resources provided by entities other than libraries.

    1. Introduction Web search engines and digital libraries usually expect the users to use search terms that most accurately represent their information needs. Finding the most appropriate search terms to represent an information need is an age old problem in information retrieval. Keyword or phrase search may produce good search results as long as the search terms or phrase(s) match those used by the authors and have been chosen for indexing by the concerned information retrieval system. Since this does not always happen, a large number of false drops are produced by information retrieval systems. The retrieval results become worse in very large systems that deal with millions of records, such as the Web search engines and digital libraries. Vocabulary control tools are used to improve the performance of text retrieval systems. Thesauri, the most common type of vocabulary control tool used in information retrieval, appeared in the late fifties, designed for use with the emerging post-coordinate indexing systems of that time. They are used to exert terminology control in indexing, and to aid in searching by allowing the searcher to select appropriate search terms. A large volume of literature exists describing the design features, and experiments with the use, of thesauri in various types of information retrieval systems (see for example, Furnas et.al., 1987; Bates, 1986, 1998; Milstead, 1997, and Shiri et al., 2002).
