Abstract

Addresses the technical and policy issues in the development of an international infrastructure for the flow of information by studying the emerging national information infrastructures in 6 post communist countries in Central and Eastern Europe. The study consisted of interviews with over 300 library managers, computing network administrators, government policy makers and other information professionals conducted in 1993 and 1994 in Croatia, the Czech Republic, Hungary, Poland, Slovakia and Slovenia, plus a 1994 mail survey of research libraries in these countries. After presenting the principles under which the G-7 leading industrialized countries have agreed to collaborate on constructing a Global Information Infrastructure (GII), presents examples from the survey on how the GII pronciples might be addressed. Results of the longitudinal study were reported at greater length in the Proceedings of the 58th Meeting of the ASIS, 1995, S.27-34

Abstract

Why devote an ARIST chapter to scholarly communication and bibliometrics, and why now? Bibliometrics already is a frequently covered ARIST topic, with chapters such as that by White and McCain (1989) on bibliometrics generally, White and McCain (1997) on visualization of literatures, Wilson and Hood (2001) on informetric laws, and Tabah (2001) on literature dynamics. Similarly, scholarly communication has been addressed in other ARIST chapters such as Bishop and Star (1996) on social informatics and digital libraries, Schamber (1994) on relevance and information behavior, and many earlier chapters on information needs and uses. More than a decade ago, the first author addressed the intersection of scholarly communication and bibliometrics with a journal special issue and an edited book (Borgman, 1990; Borgman & Paisley, 1989), and she recently examined interim developments (Borgman, 2000a, 2000c). This review covers the decade (1990-2000) since the comprehensive 1990 volume, citing earlier works only when necessary to explain the foundation for recent developments.

Abstract

Reports on a continuing project to study children's use of a graphically-based direct manipulation interface for science materials. The Science Library Catalogue (SLC), a component of project SEED, has been implemented in the libraries of 21 elementary schools in Los Angeles and will soon be implemented in a public library. The interface employs a hierarchical structure drawn from the DDC and implemented in HyperCard on the Macintosh. The study on the 2nd version of the interface indicates that children are able to use the Science Library Catalogue unaided, with reasonable success in finding items. Search success on the same topics on a Boolean command driven system was equivalent, but Boolean searches were faster. However, the Boolean system was more sensitive to differences in age, with 12-year-olds having significantly better success rates than 10-year-olds; and to search topic, with one set of questions being much easier to search than the other. On average, children liked the 2 systems about the same; the Boolean system was more attractive to certain age and gender combinations, while the Science Library Catalogue was more consistently liked across groups. results are compared to prior studies on the Science Library Catalogue and other online catalogues

Abstract

User performance on information retrieval systems is highly variable. After briefly reviewing the characterisitcs on which IR performance varies, reports on a specific study that sought to idetify both technical aptitudes and personality characteristics that were related to academic orientation variables previously found to predict IR performance. Academic orientation was related to technical aptitudes as measured by standardised achievement tests and coursework; and that academic orientation was related to some personaliyt characteristics, as measured by standardised tests. Since individual differences in information retrieval are assumed not to be random, argues that individual characteristics should be described so they can be accomodated through design and training

Abstract

The study assessed the ability of children to categorise concepts that will be used to organise an information retrieval interface. The work was done of Project SEED (Science for Early Educational Development), a project to develop hands-on science programmes for elementary schools. Aims to tailor an interface to the particular skills of children in organising science knowledge. The results are promising for the design of IR interfaces based on children's abilities to manipulate information.

Abstract

We trained 40 doctoral students to search INSPEC or ERIC on DIALOG using either the SCI-MATE menu or native commands. Each student then performed a free search on his or her chosen research topic. In comparison with 20 control subjects - doctoral students for whom a free search was performed by a skilled librarian - the experimental subjects were no less satisfied with their retrievals, which were smaller but higher in precision than the retrievals produced by the intermediaries. End-users retrieved as many relevant references as the intermediaries. Use of the menu interface did not affect quality of retrieval or user satisfaction, although subjects instructed to use native commands required less training time, and interacted more with the databases than subjects trained on the SCI-MATE menu.

Abstract

Reports on a continuing project to study children's search behaviour on an automated library catalogue designed for children, called the Science Library Catalog. This experiment exployed an advanced version of the system which combines the browsing features of earlier versions with keyword capabilities that do not require correct spelling, searching alphabetical lists, or using Boolean logic. 5th grade children are able to use browsing and keyword searchs trategies successfully, relying on browsing to familiarize themselves with the system and graduating to keyword methods after they are comfortable with the system. Children's level of science domian knowledge was found to influence both their success in finding books and their search behaviour, with children with high domain knowledge finding books more successfully and utilizing more keyword and mixed search methgods. Results contribute to understanding of the factors affecting children's search behaviour

Abstract

As we seek both to improve public school education in high technology areas and to link libraries and classrooms on the 'information superhighway', we need to understand more about children's information searching abilities. We present results of 4 experiments conducted on 4 versions of the Science Library Catalog (SLC), a Dewey Decimal based hierarchical browsing systems implemeted in HyperCard without a keyboard. The experiments were conducted over a 3-year period at 3 sites, with 4 databases, and with comparisons to 2 different keyword online catalogs. Subjects were ethnically and culturally diverse children aged 9 through 12; with 32 to 34 children participating in each experiment. Children were provided explicit instruction and reference materials for the keyword systems but not for the SLC. The number of search topics matched was comparable across all systems and all experiments; search times were comparable, thought hey varied among the 4 SLC versions and between the 2 keyword OPACs. The SLC overall was robust to differences in age, sex and computer experience. One of the keyword OPACs was subject to minor effects of age and computer experience; the other was not. We found relationships between search topic and system structure, such that the most difficult topics on the SLC were those hard to locate in the hierarchy, and those most difficult on the keyword OPACs were hard to spell or required children to generate their own search terms. The SLC approach overcomes problems with several searching features that are difficult for children in typical keyword OPAC systems; typing skills, spelling, vocabulary, and Boolean logic. Results have general implications for the desing of information retrieval systems for children

Abstract

Research in user behavior on online catalogs is in its early stages, but preliminary findings suggest that users encounter many of the same problems identified in behavioral studies of other types of bibliographic retrieval systems. Much can be learned from comparing the results of user behavior studies on these two types of systems. Research on user problems with both the mechanical aspects and the conceptual aspects of system use is reviewed, with the conclusion that more similiratiy exists across types of systems in conceptual than in mechanical problems. Also discussed are potential sources of the problems, due either to individual characteristics or to system variables. A series of research questions is proposed and a number of potential interim solutions ae suggested for alleviating some of the problems encountered by users of information systems

Abstract

40 doctoral student were trained to search INSPEC or ERIC on DIALOG using either the Sci-Mate Menu or native commands. In comparison with 20 control subjects for whom a free search was performed by an intermediary, the experiment subjects were no less satisfied with their retrievals, which were fewer in number but higher in precision than the retrievals produced by the intermediaries. Use of the menu interface did not affect quality of retrieval or user satisfaction, although subjects instructed to use native commands required less training time and interacted more with the data bases than did subjects trained on the Sci-Mate Menu. INSPEC subjects placed a higher monetary value on their searches than did ERIC subjects, indicated that they would make more frequent use of ddata bases in the future, and interacted more with the data base.

Abstract

A 5-year project to study scientific data uses in geography, starting in 1999, evolved into 20 years of research on data practices in sensor networks, environmental sciences, biology, seismology, undersea science, biomedicine, astronomy, and other fields. By emulating the "team science" approaches of the scientists studied, the UCLA Center for Knowledge Infrastructures accumulated a comprehensive collection of qualitative data about how scientists generate, manage, use, and reuse data across domains. Building upon Paul N. Edwards's model of "making global data"-collecting signals via consistent methods, technologies, and policies-to "make data global"-comparing and integrating those data, the research team has managed and exploited these data as a collaborative resource. This article reflects on the social, technical, organizational, economic, and policy challenges the team has encountered in creating new knowledge from data old and new. We reflect on continuity over generations of students and staff, transitions between grants, transfer of legacy data between software tools, research methods, and the role of professional data managers in the social sciences.

Abstract

Searching information retrieval systems is a highly interactive, iterative process that cannot be understood simply by comparing the output of a search session (the 'search product') to a query stated in advance. In this article, we examine evaluation goals and methods for studying information retrieval behavior, drawing examples from our own research and that of others. We limit our review to research that employs online monitoring, also known as transaction log analysis. Online monitoring is one of few methods that can capture detailed data on the search process at a reasonable cost; these data can be used to build quantitative models or to support qualitative interpretations of quatitative results. Monitoring is a data collection technique rather than a research design, and can be employed in experimental of field studies, whether alone or combined with other data collection methods. Based on the the research questions of interest, the researcher must determine what variables to collect from each data source, which to treat as independent varaibles to manipulate, and which to treat as dependent variables to observe effects. Studies of searching behavior often treat search task and searcher characteristics as independent variables and may manipulate other independent variables specific to the research questions addressed. Search outcomes, time, and search paths frequently are treated as dependent variables. We discuss each of these sets of variables, illustrating them with sample results from the literature and from our own research. Our examples are drawn from the Science Library Catalog project, a 7-year study of children's searching behavior on an experimental retrieval system. We close with a brief discussion of the implications of these results for the design of information retrieval systems

Abstract

In the former Yugoslavia and Soviet Bloc countries of Central and Eastern Europe most information technology was unavailable, unaffordable or discouraged for forty years. These countries realise that they must improve their internal infrastructures if they are to become integral parts of the global information infrastructure. We report the results of a mail survey conducted in late 1994 and early 1995 of 70 research libraries in Croatia, Czech Republic, Hungary, Poland, Slovakia and Slovenia, building on the findings from interviews conducted with 300 persons in the region in 1993-1994. Results show that these libraries are acquiring automated processing systems, CD-ROM databases, and connections to computer networks at a rapid rate and that automation activity has increased substantially since 1989

Abstract

The Internet would not be very useful if communication were limited to textual exchanges between speakers of English located in the United States. Rather, its value lies in its ability to enable people from multiple nations, speaking multiple languages, to employ multiple media in interacting with each other. While computer networks broke through national boundaries long ago, they remain much more effective for textual communication than for exchanges of sound, images, or mixed media -- and more effective for communication in English than for exchanges in most other languages, much less interactions involving multiple languages. Supporting searching and display in multiple languages is an increasingly important issue for all digital libraries accessible on the Internet. Even if a digital library contains materials in only one language, the content needs to be searchable and displayable on computers in countries speaking other languages. We need to exchange data between digital libraries, whether in a single language or in multiple languages. Data exchanges may be large batch updates or interactive hyperlinks. In any of these cases, character sets must be represented in a consistent manner if exchanges are to succeed. Issues of interoperability, portability, and data exchange related to multi-lingual character sets have received surprisingly little attention in the digital library community or in discussions of standards for information infrastructure, except in Europe. The landmark collection of papers on Standards Policy for Information Infrastructure, for example, contains no discussion of multi-lingual issues except for a passing reference to the Unicode standard. The goal of this short essay is to draw attention to the multi-lingual issues involved in designing digital libraries accessible on the Internet. Many of the multi-lingual design issues parallel those of multi-media digital libraries, a topic more familiar to most readers of D-Lib Magazine. This essay draws examples from multi-media DLs to illustrate some of the urgent design challenges in creating a globally distributed network serving people who speak many languages other than English. First we introduce some general issues of medium, culture, and language, then discuss the design challenges in the transition from local to global systems, lastly addressing technical matters. The technical issues involve the choice of character sets to represent languages, similar to the choices made in representing images or sound. However, the scale of the language problem is far greater. Standards for multi-media representation are being adopted fairly rapidly, in parallel with the availability of multi-media content in electronic form. By contrast, we have hundreds (and sometimes thousands) of years worth of textual materials in hundreds of languages, created long before data encoding standards existed. Textual content from past and present is being encoded in language and application-specific representations that are difficult to exchange without losing data -- if they exchange at all. We illustrate the multi-language DL challenge with examples drawn from the research library community, which typically handles collections of materials in 400 or so languages. These are problems faced not only by developers of digital libraries, but by those who develop and manage any communication technology that crosses national or linguistic boundaries.

Abstract

"Big Data" is on the covers of Science, Nature, the Economist, and Wired magazines, on the front pages of the Wall Street Journal and the New York Times. But despite the media hyperbole, as Christine Borgman points out in this examination of data and scholarly research, having the right data is usually better than having more data; little data can be just as valuable as big data. In many cases, there are no data -- because relevant data don't exist, cannot be found, or are not available. Moreover, data sharing is difficult, incentives to do so are minimal, and data practices vary widely across disciplines. Borgman, an often-cited authority on scholarly communication, argues that data have no value or meaning in isolation; they exist within a knowledge infrastructure -- an ecology of people, practices, technologies, institutions, material objects, and relationships. After laying out the premises of her investigation -- six "provocations" meant to inspire discussion about the uses of data in scholarship -- Borgman offers case studies of data practices in the sciences, the social sciences, and the humanities, and then considers the implications of her findings for scholarly practice and research policy. To manage and exploit data over the long term, Borgman argues, requires massive investment in knowledge infrastructures; at stake is the future of scholarship.
