Abstract

Cataloguers need to create and harness flexibility and commitment in order to develop a cataloguing strategy. This can be done through developing trust. Explains how the British Library Cataloguing Department is attempting to carry out a strategy of rethinking its values and agreeing a programme of action for achieving them. The key elements of this strategy are cooperation in record creation, and training and development of professionally assertive and flexible staff

Abstract

The Wolverhampton Web Library (WWLib) is a WWW search engine that provides access to UK based information. The experimental version developed in 1995, was a success but highlighted the need for a much higher degree of automation. An interesting feature of the experimental WWLib was that it organised information according to DDC. Discusses the advantages of classification and describes the automatic classifier that is being developed in Java as part of the new, fully automated WWLib

Abstract

Contends that quality in a catalogue is crucially related to its capability to deliver the services it is intended to provide: enabling a user to find a book of which the author, title or subject is known; and to show what the library has be a given author or on a given subject or in a given kind of literature. Describes changes in recent years which have implications for the choice of a retrieval system for library users. Discusses 2 types of problems experiences by users wanting to harness the potential of OPACs. These include: problems with the system itself. Describes the role of the cataloguer today which is essentially to interface the users with the retrieval system

Abstract

Revised version of a paper presented at the Annual Conference of the Association of Canadian Archivists, Montreal, 12 Sept 92. The challenges raised by electronic records present an opportunity to define the essential purposes for description: to reassess its objectives, agents and timing; and to imagine new approaches that harness the power of information technology while respecting archival principles. Discusses how archival description must support the need to identify, gain access, understand the meaning, interpret the content, determine authenticity, and manage electronic records to ensure continuing access. Proposes management of metadata as an alternative strategy to current descriptive practices

Abstract

Presents a range of pessimistic and optimistic predictions for the future of the library. Foresees research libraries being more financially pressed and reducing acquisitions in isolation and in an uncoordinated manner. Also predicts that older materials will become less accessible, and that the nature of access will increasingly influence the nature of scholarly inquiry. Notes the optimistic promises of the virtual library, but argues that librarians will have to become more active, and harness the resources of the electronic world rather than simply learning about and playing with them. Also librarians must ask themselves how the routine ways of doing things might be done differently, given the new context of their work

Abstract

Reports on a research project to evaluate and compare Boolean searching and methods of query reformulation using ranked output retrieval. Illustrates the design and operating features of the ranked output system, called ROSE (Ranked Output Search Engine), by means of typical results obtained by searching a database of 1239 records on the subject of cystic fibrosis. Concludes that further work is needed to determine the best reformulation tactics needed to harness the professional searcher's intelligence with that much more limited intelligence provided by the search software

Abstract

Reviews the significant changes in information technology over the last 50 years and considers the many implications for information services. The Internet, global access to distributed information sources, and remote users all present challenges to would-be providers of information services. As resources proliferate, the information professional must develop new methods for locating and accessing them: reliance on publishers and reviews is no longer sufficient. Information service providers can now serve more diverse clienteles, but must be aware of the greater range of information needs and styles of information seeking. The continuing challenge is to harness the information technologies to meet these needs

Abstract

Content-based retrieval (CBR) promises to greatly improve capabilities for searching for images based on semantic features and visual appearance. However, developing a framework for evaluating image retrieval effectiveness remains a significant challenge. Difficulties include determining how matching at different description levels affects relevance, designing meaningful benchmark queries of large image collections, and developing suitable quantitative metrics for measuring retrieval effectiveness. This article studies the problems of developing a framework and testbed for quantitative assessment of image retrieval effectiveness. In order to better harness the extensive research on CBR and improve capabilities of image retrieval systems, this article advocates the establishment of common image retrieval testbeds consisting of standardized image collections, benchmark queries, relevance assessments, and quantitative evaluation methods

Abstract

Metadata has taken an a new took with the advent of XML and digital resources. XML provides a new versatile structure for tagging and packaging metadata as the rapid proliferation of digital resources demands both rapidly produced descriptive data and the encoding of more types of metadata. Two emerging standards are attempting to harness these developments for library needs. The first is the Metadata Object and Description Schema (MODS), a MARC-compatible XML schema for encoding descriptive data. The second standard is the Metadata Encoding and Transmission Standard (METS), a highly flexible XML schema for packaging the descriptive metadata and various other important types of metadata needed to assure the use and preservation of digital resources.

Abstract

Presents a Guided tour system for the WWW, called Ariadne, which implements the ideas of trails and guided tours, originating from the hypertext field. Ariadne appears as a Java applet to the user and it stores guided tours in a database format separated from the WWW documents included in the tour. Itd main advantages are: an independent user interface which does not affect the layout of the documents being part of the tour, branching tours where the user may follow alternative routes, composition of existing tours into aggregate tours, overview map with indication of which parts of a tour have been visited an support for getting back on track. Ariadne is available as a research prototype, and it has been tested among a group of university students as well as casual users on the Internet

Abstract

Despite the rapid growth in social network sites and in data mining for emotion (sentiment analysis), little research has tied the two together, and none has had social science goals. This article examines the extent to which emotion is present in MySpace comments, using a combination of data mining and content analysis, and exploring age and gender. A random sample of 819 public comments to or from U.S. users was manually classified for strength of positive and negative emotion. Two thirds of the comments expressed positive emotion, but a minority (20%) contained negative emotion, confirming that MySpace is an extraordinarily emotion-rich environment. Females are likely to give and receive more positive comments than are males, but there is no difference for negative comments. It is thus possible that females are more successful social network site users partly because of their greater ability to textually harness positive affect.

Abstract

Green information technology (IT) initiatives cannot be implemented in isolation if they are to have a significant and lasting impact on environmental sustainability. Instead, there is a need to harness the collective IT resources of the diverse stakeholders operating in the interorganizational business networks that characterize the contemporary business landscape. This, in turn, demands an appropriate leadership structure. However, the notion of "green leadership" has not received adequate research attention to date. Using a case study of green IT implementation at China Mobile, the world's largest mobile telecommunications provider, this study seeks to shed light on the underlying process through which green leadership is achieved and subsequently enacted to facilitate collective green IT initiatives. With its findings, this study presents a process theory that complements the dominant, internally-oriented perspective of green IT and provides practitioners with a useful reference for leveraging the collective IT resources of their network partners to contribute toward preserving the environment for future generations.

Abstract

The importance of involving humans in the data science process has been widely discussed in the literature. However, studies lack details on how to involve humans in the process. Using a design science approach, this paper proposes and evaluates a human-supervised data science framework in the context of local governments. Our findings suggest that the involvement of a stakeholder group, public managers in this case, in the process of data science project enhanced quality of data science outcomes. Public managers' detailed knowledge on both the data and context was beneficial for improving future data science infrastructure. In addition, the study suggests that local governments can harness the value of data-driven approaches to policy and decision making through focalized investments in improving data and data science infrastructure, which includes culture and processes necessary to incorporate data science and analytics into the decision-making process.

Abstract

The integration of Artificial Intelligence (AI) chatbots in higher education institutions (HEIs) is reshaping the educational landscape, offering opportunities for enhanced student support and administrative efficiency. This study explores the future implications of AI chatbots in HEIs, aiming to understand their potential impact on teaching, learning, and research processes. Utilizing a narrative literature review (NLR) methodology, this study synthesizes existing research on AI chatbots in higher education from diverse sources, including academic databases and scholarly publications. The findings highlight the transformative potential of AI chatbots in streamlining administrative tasks, enhancing student learning experiences, and supporting research activities. However, challenges such as academic integrity concerns, user input understanding, and resource allocation pose significant obstacles to the effective integration of AI chatbots in HEIs. This study underscores the importance of proactive measures to address ethical considerations, provide comprehensive training for stakeholders, and establish clear guidelines for the responsible use of AI chatbots in higher education. By navigating these challenges, and leveraging the benefits of AI technologies, HEIs can harness the full potential of AI chatbots to create a more efficient, effective, inclusive, and innovative educational environment.
