Abstract

Reports research, conducted on the UTLink online catalogue at Toronto University Library, aimed at examining the provision of library staff assistance to users of OPACs. The study identified a significant change in the demand for service when there was a change from offering traditional 'from the desk' help to 'point of use' help at the OPAC terminals. The kind of help most given by librarians was procedural: a frequent problem being how to deal with information overload. Results suggest that while it is important to continue to improve the technology there remains an ongoing need for human support. Research into human help is supportive of library practice, which values the provision of high quality services to users who are not yet self sufficient on OPACs

Abstract

In order to evaluate the features and functionality of the online help system for the NOTIS (version 5.1) OPAC. a set of performance enhancing features were gathered from a review of research studies of online help systems, 25 features were identified and organized into 4 categories: user training, interface; access to system commands; and massage content and display. The evaluation revealed that the NOTIS online help system fared poorly in user training features, fared well in user interface; was substandard in access to system commands, and moderately well in message content and display. Concludes that the NOTIS help system is probably no better and no worse than that of other library systems but is adequate

Abstract

Die Entstehung von Social Software ermöglicht es Nutzern, in großem Umfang im Netz zu publizieren. Bisher liegen aber nur wenige empirische Befunde zu funktionalen Eigenschaften sowie Qualitätsaspekten von Nutzerbeiträgen im Kontext von Informationsmanagement und Information Retrieval vor. Diese Arbeit diskutiert grundlegende Partizipationsformen, präsentiert empirische Studien über Social Tagging, Blogbeiträge sowie Relevanzbeurteilungen und entwickelt Design und Implementierung einer "sozialen" Informationsarchitektur für ein partizipatives Onlinehilfesystem.

Abstract

Describes the creation and results of a questionnaire survey of cataloguers in 6 Singapore academic and national libraries and of their vendor helpdesk staff to evaluate the help systems of library automation systems, with particular emphasis on the cataloguing function. Describes the structure of the questionnaire; the methodology used to analyse the data; the profile of the respondents and the systems used by them; and the implications of the statistical results. Functionalities for the following help features were surveyed: getting in and out of the help systems; selecting a relevant topic; formulating queries; searching of information; completeness and comprehensiveness of the help system; navigation to other topics; applying information to solve problems; and data entry and authority control in cataloguing tasks. Data analysis identified 27 preferred features which could be taken into account in the product development of online help systems

Abstract

Today, more and more software packages come with online documentation. Some have complete manuals as well. Others have basic documentation on paper and more advanced information online. I recently purchased a computer that came with 20 software programs and not one page of written documentation. More and more, users have to find information by searching online. Most documentation teams focus on writing and ignore the problems of information retrieval, making information in printed documents difficult to find, and online information impossible to find. With online Help, you cannot browse the documentation. You cannot even browse more than a couple of inches of the index at a time. If online users do not get superb guidance into the jungle of online Help, they go away like the hero of Joseph Conrad's Heart of Darkness, saying "Oh, the horror! The horror!" How does an online Help index work? The following examples are based on the Windows 95 Help-type system, but do not represent actual Help screens

Abstract

This article introduces a new concept and technique for information retrieval called 'colinked descriptors'. Borrowed from an analogous idea in bibliometrics - cocited references - colinked descriptors provide a theory and method for identifying search terms that, by hypothesis, will be superior to those entered initially by a searcher. The theory suggests a means of moving automatically from 2 or more initial search terms, to other terms that should be superior in retrieval performance to the 2 original terms. A research project designed to test this colinked descriptor hypothesis is reported. The results suggest that the approach is effective, although methodological problems in testing the idea are reported. Algorithms to generate colinked descriptors can be incorporated easily into system interfaces, front-end or pre-search systems, or help software, in any database that employs a thesaurus. The potential use of colinked descriptors is a strong argument for building richer and more complex thesauri that reflect as many legitimate links among descriptors as possible

Abstract

For more than thirty years thesauri have been valuable tools in information retrieval. Originally, the basic function of the thesauri was to help the indexer to transform concepts and their relationships, as expressed in the language of documents, into the more regularised indexing language of catalogues and databases. In the nineties another important purpose of the thesauri is to guide the searcher to the best search terms. In spite of the new role, the design of the thesauri has remained more or less stable. This paper explores the demands which are put on the thesauri in relation to searching. Findings are presented in the form of generalisations and moreover illustrated in relation to a real-life situation. Suggestions for improved functionality are presented in the form of a prototype of a thesaurus record. The new role as a conceptual searching tool is also influencing the construction process. Therefore, the paper ends up with a discussion of new methods for thesaurus construction

Abstract

The need for thesauri to help users in their search for information in online information systems has been discussed for several decades. Many wide-ranging contributions have been made to solve this problem. Nevertheless, investigation is needed to design a thesaurus structure based on what is relevant for users and generators of information within a specific subject domain. Explores the possibility of creating a thesaurus from the cognitive viewpoint. This approach is based on a system that organizes its representation of knowledge or its classification as closely as possible to the authors' and users' images of the subject domain with the objective of increasing the interaction between users and texts, and thus the communication in a given information retrieval system. Discourse analysis is used as a main method to identify the categories and its relevance for building such a structure is discussed

Abstract

In industrialized countries, the rapidity of development has not taken into account the fact that it would be opportune to formalize "niche" knowledge. There is an ever-growing need for a written formalization of tacit knowledge. The aim of this activity consists in building specialized knowledge collections, which are useful to help and to guarantee the continuity of small and medium-sized business during successions, and to guarantee staff training related to specific practices. To reach this aim, this work presents the construction of a faceted thesaurus (GoldThes) for the domain of goldsmith handcraftsmanship, which tries to classify and organize a domain extracted from a regional context. The use of this kind of system demonstrated how classifying and organizing information into multi-dimensional hierarchies makes it more accessible than using a single taxonomy, that is a unique hierarchical dimension.

Abstract

The task of an information architect is to create web sites where users can actually find the information they are looking for. As the ocean of information rises and leaves what we seek ever more deeply buried in what we don't seek, this discipline becomes ever more relevant. Information architecture involves many different aspects of web site creation and organization, but its principal tools are information organization techniques developed in other disciplines. Most of these techniques come from library science, such as thesauri, taxonomies, and faceted classification. Topic maps are a relative newcomer to this area and bring with them the promise of better-organized web sites, compared to what is possible with existing techniques. However, it is not generally understood how topic maps relate to the traditional techniques, and what advantages and disadvantages they have, compared to these techniques. The aim of this paper is to help build a better understanding of these issues.

Abstract

Traces the origin of the term librametry. Shows how librametry has helped Ranganathan to develop the staff formula for different libraries, and it can help in decision making relating to the establishment of rural and branch libraries; dormitory and service libraries. His maintenance of statistics of various library activities showed the growth pattern of library collection, use of the collection by users, busy and very busy hours in the circulations and reference sections, and so on. He also developed a method for optimal procurement of books for every department in the university. Ranganathan also showed statistically that on average Colon class numbers are shorter than DC class numbers. With the passage of time bibliometrics overshadowed librametrics. Ranganathan did not define librametrics, neither he isolated its components. The lacunae have been filled in this article. It has also been shown that a substantial part of librametrics is occupied by bibliometrics.

Abstract

Colon Classification (CC), based on dynamic theory of classification saw seven editions from 1928 to 1987. Libraries practising it continued with extensions and additions carried out to meet their needs since it was not revised for long after the 7th edition. Revision requires adding terms in different disciplines, organising them in relation to each other and assigning notation for shelf classification. Use of ICT would help in reviving CC and is essential for regular revision of a classification scheme. The paper explores the possibility for creation of an expert system through the design of Web based Colon Classification. The author explores the possibility by designing a prototype for online revision of Colon Classification in the paper.

Abstract

This paper illustrates the changing role of thesauri interlinked with overall changes of modern information infrastructure services, referring to "STW Thesaurus for Economics" as a case study. It starts with an overview of the history and development of the STW and describes the far-reaching changes brought about by its publication on the Web, with regard to subject indexing, retrieval and new uses for Linked Open Data. It argues that only the most recent technological developments help thesauri to exploit their full potential which is why they more than ever have a place in current information retrieval and infrastructure.

Abstract

Thesauri are knowledge models commonly used for information classication and retrieval whose structure is dened by standards that describe the main features the concepts and relations must have. However, following these standards requires a deep knowledge of the field the thesaurus is going to cover and experience in their creation. To help in this task, this paper describes a software processing chain that provides dierent validation components that evaluates the quality of the main thesaurus features.

Abstract

The 'data revolution' has impacted researchers across the disciplines. As if the traditional work of teaching, competing for grants and promotion, doing research and publishing results was not challenging enough, researchers are required to make fundamental changes in the way they do all of these things. A similar shift can be seen for academic librarians. Librarians who were taught to meet the needs of their users based on information scarcity now need to retrain themselves to help users deal with information overload. Moreover, librarians increasingly find themselves 'upstream' in the research process, trying to assist their users in managing unwieldy amounts of data when their comfort zone is firmly 'downstream' in the post-publication stage. Unsettling as it may be, these are exciting developments for the library profession.
