The Unesco Statistical Yearbook includes in its annual volumes tables reporting the number of books published by countries in subject classes according to the UDC classification system. These statistics are examined to assess global trends in subjects areas such as pure, social, medical, and applied sciences, and literature. Data from Asia, Latin America, Africa, and North America are found to be highly inconclusive due to nonreporting patterns. Data from Europe and the USSR are more comprehensive. According to these data, social science titles form the largest percentages of the world's production, followed by applied sciences and literature. Overall, literature and medical science titles appear to be increasing in production faster than other subject areas. Gretchen Whitney is an assistant professor at the Graduate Library School of the University of Arizona and author ofLanguage Distribution in Databases. She teache in the fields of information science and information policy.  相似文献

Abstract

This survey examines the basic needs of Harvard Law Faculty for information about new books and current journal articles. The purpose of this survey was to examine new media and technology in order to develop better current awareness tools, to better utilize the online catalog as a method of delivering current information to faculty, and to produce a new publication that fills in the gaps left by Current Index to Legal Periodicals and other sources. This survey looks at the production and circulation of photocopied pages of law reviews, recent acquisition lists, document delivery and interdisciplinary current awareness needs.  相似文献

This study of reviews in six scholarly journals of books on U.S. history examines the sources of books reviewed; their prices, length, and other characteristics; the affiliations of the reviewers; and the timeliness and coverage of reviews. The findings indicate that, although historians rely on reviews in scholarly journals for information on current publications, these reviews are in some ways inadequate for their purposes.  相似文献

ABSTRACT

Rather than create a collection solely to support distance learners, libraries should consider the needs of all customers when developing a digital library. The acceptance of digital libraries is dependant upon the conversion of resources to an electronic format that is easy to use and is fully searchable. While electronic journals are widely accepted by most academic library customers, the delivery of online books has had a very different acceptance rate. Rather than support the sequential reading of books, electronic books are commonly used to find information and can be particularly well-suited for reference purposes. This article will provide insight into the history of e-book models and evaluate the usage statistics of a large electronic book collection in an academic library.  相似文献

The National electronic Library for Health (NeLH) is now taking shape, as the virtual branch libraries begin to accumulate ‘books’, among their resources. In the Primary Care branch ( http://www.nelh‐pc.nhs.uk ), one of the first available books was the Statement of Fees and Allowances (otherwise known as the Red Book). While being held up as an example of what the NeLH can offer, this book and the story of its transformation from paper to Internet format is a powerful example of how much further the National Health Service (NHS) must go before it can claim to be fully exploiting the benefits of information technology (IT). This article refers to the author’s experience in producing electronic books for primary care using WaX software, and an example of a process change from paper to screen that was managed within a university administrative office. The author suggests that to reap optimal benefits from IT, the NeLH and its collaborators must address the fundamental issues of people and the paper‐based processes used by information providers. The NeLH must work with both NHS IT trainers and information providers in a three‐way collaboration involving key people and processes, to achieve the efficient production of an updateable and user‐friendly library of electronic books.  相似文献

Hierarchical Text Categorization (HTC) is the task of generating (usually by means of supervised learning algorithms) text classifiers that operate on hierarchically structured classification schemes. Notwithstanding the fact that most large-sized classification schemes for text have a hierarchical structure, so far the attention of text classification researchers has mostly focused on algorithms for “flat” classification, i.e. algorithms that operate on non-hierarchical classification schemes. These algorithms, once applied to a hierarchical classification problem, are not capable of taking advantage of the information inherent in the class hierarchy, and may thus be suboptimal, in terms of efficiency and/or effectiveness. In this paper we propose TreeBoost.MH, a multi-label HTC algorithm consisting of a hierarchical variant of AdaBoost.MH, a very well-known member of the family of “boosting” learning algorithms. TreeBoost.MH embodies several intuitions that had arisen before within HTC: e.g. the intuitions that both feature selection and the selection of negative training examples should be performed “locally”, i.e. by paying attention to the topology of the classification scheme. It also embodies the novel intuition that the weight distribution that boosting algorithms update at every boosting round should likewise be updated “locally”. All these intuitions are embodied within TreeBoost.MH in an elegant and simple way, i.e. by defining TreeBoost.MH as a recursive algorithm that uses AdaBoost.MH as its base step, and that recurs over the tree structure. We present the results of experimenting TreeBoost.MH on three HTC benchmarks, and discuss analytically its computational cost.

Methods for automatically evaluating answers to complex questions   总被引:1,自引:0,他引:1  
Evaluation is a major driving force in advancing the state of the art in language technologies. In particular, methods for automatically assessing the quality of machine output is the preferred method for measuring progress, provided that these metrics have been validated against human judgments. Following recent developments in the automatic evaluation of machine translation and document summarization, we present a similar approach, implemented in a measure called POURPRE, an automatic technique for evaluating answers to complex questions based on n-gram co-occurrences between machine output and a human-generated answer key. Until now, the only way to assess the correctness of answers to such questions involves manual determination of whether an information “nugget” appears in a system's response. The lack of automatic methods for scoring system output is an impediment to progress in the field, which we address with this work. Experiments with the TREC 2003, TREC 2004, and TREC 2005 QA tracks indicate that rankings produced by our metric correlate highly with official rankings, and that POURPRE outperforms direct application of existing metrics.

Technology today more than ever has a disruptive impact on publishing. The Internet, printing-on-demand and the e-book are the main drivers of change, impacting all aspects of the publishing value chain—from the way books are published (authors can go direct to the reader), distributed (electronic marketplaces), sold (e-tailers) and read (electronic books). The author examines the context of the publishing industry in which these changes are occurring, describes the main drivers and impacts of these changes and illustrates them with an example from the information publishing industry. This paper is based on a presentation made during the conference ‘Blinded by the E-Light’ sponsored by Vista Computer Services (www.vistacomp.com) on June 15, 2000 in New York, NY.  相似文献

This work is an annotated bibliography that consists of articles, books, conference papers, dissertations, reports, etc. published in various library and information science forums on the subject of librarianship in the Maghreb. The goal of preparing this work is to provide a list of citations with abstracts that librarians, library students, and library scholars can use to perform research within this subject area and further the body of knowledge. The research methodology that was used to find these citations involved searching the database versions of ERIC, Dissertations Abstracts Online, and Library Literature within the online public access catalog of the Auburn University library system. It also involved searching the online databases of Library and Information Science Abstracts (LISA), British Education Index, andEducation Abstracts within the DIALOG database as well as the respective print versions of these resources. While this work is by no means an exhaustive critique of the entire Maghrebi library and information science literature, it does strive to be comprehensive in terms of its country-by-country analysis of librarianship and information science within the region. In providing a citation for a non-English language work, the English equivalent of the title of that work will be given next to the non-English title.  相似文献

Abstract

Universities struggle to offer complete, up-to-date and consistent information about their key assets to their numerous users across various digital services and communication channels. Key assets include people, papers, books, dissertations, patents, courses, and research projects. The main difficulty stands in the intrinsic data fragmentation and data diversity: data about the key assets is scattered across multiple information silos, data is often duplicated and difficult to correlate due to the diversity in the format, metadata, conventions, and terminology used. We illustrate how this difficulty can be tackled and describe the work carried out at the University of Trento in Italy.  相似文献

Abstract

This paper attempts to shed some light on the scientific communication behavior of Arab authors in library and information science by studying the characteristics of the literature used by these authors. A bibliometric study by way of citation analysis was conducted on the articles published from 1978 to 1988 in Maktabat Al-Idarah, an elite Arab scholarly journal in the field. It was concluded from this study that English literature is the main source of information for Arab authors in library and information science. They rely on English literature that is between 5 and 15 years of age more than on their own literature and use books more than any other form of publication. They cover almost all areas of the field with special emphasis on technical services as represented by cataloging, classification and aquisition, library administration and library education. Local materials published in their own country were also important.  相似文献

An examination of the issue of literary massification and degradation of taste in the light of how locally organized reading groups select and respond to books. Although commodification does somewhat narrow the universe of choice for these groups it seems less important in shaping their use of books than are the opinions of cultural authorities or the reader’s own personal experience. Further, the responses of these readers of “good” books resemble in certain ways what is known of reader responses to mass market books, which also undermine a rigid dichotomy between high culture and mass culture.  相似文献

This is the fourth part of a comprehensive, quantitative study of biomedical book reviews. The data base of the total project was built from statistics of 3,347 reviews of 2,067 biomedical books taken from all 1970 issues of fifty-four reviewing journals. This part of the study identifies the major American and British biomedical book publishers in terms of their quantitative production of book titles reviewed, and determines the relationships among these publishers. It is found that Williams & Wilkins, Charles C Thomas, Academic Press, and Springer Verlag are the most productive biomedical book publishers in terms of books reviewed in 1970. These four publishers accounted for 32% of the 1,674 books available in the United States and reviewed in the reviewing media in 1970. Williams & Wilkins is especially significant by virtue of reprint activity. The present study also explores the price trend of biomedical books. It is found that the mean price for 1,077 books studied was $16.20 per volume, with a standard deviation of $9.42.  相似文献

ABSTRACT

The history of Christian censorship up to the sixteenth century reveals scattered attempts to censor works of individual authors, but neither a systematic effort to formulate rules for regulating printers, booksellers, and authors, nor an effort to compile a comprehensive list of prohibited books. The first such attempt was made by the Council of Trent, which formulated a set of rules for printing, selling, and censoring books. These “Tridentine rules” were accompanied by a list of forbidden books, and together they formed the first Index Librorum Prohibitorum (1564). The Index underwent many revisions, the most important being the 1900 edition of Pope Leo XIII, which replaced the Tridentine rules with a set of Decreta Generalia on censoring and prohibiting books. Publication of the Index continued until its abolition in 1966. The reasons for its demise include the triumph of the Reformation and the rise of the nation-state, mass literacy, and mass communications.  相似文献
