Abstract

The authors describe user interface tools based on search histories to support legal information seekers. The design of the tools was informed by the results of a user study (Komlodi, 2002a) that examined the use of human memory, external memory aids, and search histories in legal information seeking and derived interface design recommendations for information storage and retrieval systems. The data collected were analyzed to identify potential task areas where search histories can support information seeking and use. The results show that many information-seeking tasks can take advantage of automatically and manually recorded history information. These findings encouraged the design of user interface tools building on search history information: direct search history displays, history-enabled scratchpad facilities, and organized results collection tools.

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

The purpose of this exploratory study is to develop research methods to compare the effectiveness of two video browsing interface designs, or surrogates-one static (storyboard) and one dynamic (slide show)-on two distinct information seeking tasks (gist determination and object recognition). Although video data is multimodal, potentially consisting of images, speech, sound, and text, the surrogates tested depend on image data only and use key frames or stills extracted from source video. A test system was developed to determine the effects of different key frame displays on user performance in specified information seeking tasks. The independent variables were interface display and task type. The dependent variables were task accuracy and subjective satisfaction. Covariates included spatial visual ability and time-to-completion. The study used a repeated block factorial 2x2 design; each of 20 participants interacted with all four interface-task combinations. No statistically significant results for task accuracy were found. Statistically significant differences were found, however, for user satisfaction with the display types: users assessed the static display to be "easier" to use than the dynamic display for both task types, even though there were no performance differences. This methodological approach provides a useful way to learn about the relationship between surrogate types and user tasks during video browsing

Abstract

Purpose - The purpose of this paper is to present a high-level investigation of the physical-conceptual continuum occupied by both digital and physical libraries. Design/methodology/approach - A framework is provided for thinking about the notions of place and library. The issue of materials and the ideas they represent is considered. Places for people are considered, including issues of people's sense of place in physical and digital spaces. The issue of physical and digital spaces as places for work, collaboration, and community-building is considered. Findings - As more digital libraries are built, and as more physical libraries offer electronic access to parts of their collection, two trends are likely to result: the role of the library as a storage space for materials will become decreasingly important; and the role of the library as a space for users, for individual and collaborative work, and as a space for social activity, will become increasingly important. Research limitations/implications - Digital libraries are unable to fulfill some of the functions of the physical library as physical spaces, but are able to offer functions beyond what the physical library can offer as cognitive spaces. Practical implications - Areas of likely future development for digital libraries are suggested, as vehicles for enhancing cognitive space by augmenting representations of ideas in materials. Originality/value - This paper argues that in many ways digital libraries really are places in the conceptual sense, and will continue to broaden and enrich the roles that libraries play in people's lives and in the larger social milieu.

Abstract

This is a propitious time for information science. The WWW has propelled information services into the public eye as never before, and information professionals are sought out in all walks of life to assist people with work, learning and play in the information environment. Classical information retrieval has yielded novel techniques for applying computers to retrieval problems, including WWW search engines. The classical model of retrieval is one of matching queries to documents and ranking these matches. It is apparent, however, that a new model of retrieval is needed as people access large-scale digital libraries of multimedia content and vast collections of unstructured data in the WWW. What is needed are ways to bring human intelligence and attention more actively into the search process. To this end, researchers are beginning to combine the lessons from designing highly interactive user interfaces with the lessons from human information behavior to create new kinds of search systems that depend on continuous human control of the search process. I call this hybrid approach to the challenges of information seeking, human-computer information retrieval (HCIR). Though human-computer information interaction is perhaps a more expansive and appropriate phrase, the HCIR phrase unites two well-known fields/communities of practice and is thus adopted here. HCIR aims to empower people to explore large-scale information bases but demands that people also take responsibility for this control by expending cognitive and physical energy. This paper outlines the basic motivations and concepts of HCIR and presents design goals and challenges that are informed by two ongoing HCIR projects.
