Abstract

Explores the idea that virtual books will send printed books into obsolescnece within the next decade giving rise to either book museums or to virtual libraries. The evidence suggestss that because librarians value confidentiality, intellectual freedom, users' ability to find information independently, awareness of their role in the community, literacy and continuing professional education, their educational role in helping users to navigate collections of books will not become redundant with the growth of electronic resources. Explores these trends in an art library context focusing on the indispensible nature of the art librarian

Abstract

Constructivism palces emphasis on helping learners create or modify internal models on which to build knowledge and foster experiences which facilitate further knowledge construction. An understanding of models and the use of analogy can be a tool to help facilitate understanding and knowledge construction in new learning environemnts such as the Internet

Abstract

A growing demand for digital documents is redefining the meaning of document delivery and repositioning the role it plays in libraries. Other trends helping to bring about these changes include the increasing sophistication of information technologies, new library philosophies and the prevalence of information 'pointers' such as bibliographic databases. Studies of delivery system usage have shown digital documents can meet a variety of research needs. Criteria for evaluating document delivery systems and services include consistency, dependability, rapid turnaround and ease of integration

Abstract

Asserts that although the library landscape may shift a great deal, reference librarians will still be in the business of negotiating with users and helping them find what they need. The electronic environment may cause a shift in the tools librarians use and the speed in which they change; it may also allow them to look more closely at their users' needs and deliver what they request more quickly and in a wider variety of forms

Abstract

The Ambient Wood project, carried out as part of the Equator project, set out to provide an augmented learning experience for children in an outdoor environment. Using a variety of devices, the children gathered information about the woodland habitats performing basic scientific enquiry and hypothesis testing. In this paper, we describe the supporting information infrastructure used in the project, focusing on how hypermedia tools and techniques were used to structure and deliver the information to the children, helping to orchestrate the learning activities.

Abstract

This study investigates the motivational factors affecting the quantity and quality of voluntary knowledge contribution in online Q&A communities. Although previous studies focus on knowledge contribution quantity, this study regards quantity and quality as two important, yet distinct, aspects of knowledge contribution. Drawing on self-determination theory, this study proposes that five motivational factors, categorized along the extrinsic-intrinsic spectrum of motivation, have differential effects on knowledge contribution quantity versus quality in the context of online Q&A communities. An online survey with 367 participants was conducted in a leading online Q&A community to test the research model. Results show that rewards in the reputation system, learning, knowledge self-efficacy, and enjoy helping stand out as important motivations. Furthermore, rewards in the reputation system, as a manifestation of the external regulation, is more effective in facilitating the knowledge contribution quantity than quality. Knowledge self-efficacy, as a manifestation of intrinsic motivation, is more strongly related to knowledge contribution quality, whereas the other intrinsic motivation, enjoy helping, is more strongly associated with knowledge contribution quantity. Both theoretical and practical implications are discussed.

Abstract

An HTTP based resource discovery system called Discover has been built that provides a single point of access to over 500 WAIS servers. Discover provides 2 key services: query refinement and query routing. Query refinement helps a user improve a query fragment to describe the user's interests more precisely. Once a query has been refined and describes a manageable result set, query routing automatically forewards the query to the WAIS servers that contain relevant documents. Abbreviated descriptions of WAIS sites called content lables are used by the query routing provides an effective way to discover resources in a large universe of documents. Expansion of query fragments is essential in helping one use a large, dynamically changing, heterogenous distributed information system

Abstract

Challenges the mind sets that exist about cataloguing in libraries today by offereing arguments for new priorities based on a formula of blending the users' needs with the need for libraries to take a more proactive role in helping users find and use information relevant to their learning needs in a world of rapid and complex change. Argues that inhouse cataloguing is in decline due to the explosion of technological innovations and a high demand for new services pushing for a new order of priorities to ensure effective management at a time of shrinking resources. Focuses on examples from the university environment

Abstract

OCLC's NetFirst Internet database includes DDC numbers and LoC subject headings to facilitate access to resources. 3 OCLC research projects are helping explore the potential of DDC as a knowledge-structuring tool for large collections of electronic documents. The Scorpion system explores indexing and cataloguing of electronic resources, with emphasis on building tools for automatic subject recognition using schemes like the DDC. Dewey ETC Trees and Wordsmith are concerned with expanding the Deqey knowledge based and enhancing the vocabulary and terminology of the DDC

Abstract

MedLine Search Assistant is a new interface for MEDLINE searching. The interface is designed to (1) visualize boolean query building process, (2) extract descriptors (MeSH terms) automatically from the retrieved documents and list them in the order of their occurrence frequencies, (3) guide the user's query modification process through the display of the number of hits, and (4) allow the user to "pick-and-choose" from a list of related MeSH terms to construct search queries. MedLine Search Assistant improves both search precision and recall by helping the user convert a free text search to a controlled vocabulary-based search in a visual environment

Abstract

The widely used Web search engines index and recommend individual Web pages in response to a few keywords queries to assist users in locating relevant documents. However, the Web search engines give different users the same answer set, although the users may have different preferences. A personalized Web search would carry out the search for each user according to his or her preferences. To conduct the personalized Web search, the authors provide a novel approach to model the user profile with a self-organizing map (SOM). Their results indicate that SOM is capable of helping the user to find the related category for each query used in the Web search to make a personalized Web search effective.

Abstract

This paper discusses and illustrates through examples how meaningful or deep learning can be supported through well-structured presentation of material, through giving learners schemas they can use to organize knowledge in their minds, and through helping learners to understand knowledge organization principles they can use to construct their own schemas. It is a call to all authors, educators and information designers to pay attention to meaningful presentation that expresses the internal structure of the domain and facilitates the learner's assimilation of concepts and their relationships.
