俄文连续出版物联机编目规则在我国尚没有统一的标准,只有少数图书馆按照自定规则实现了俄文连续出版物的计算机管理。黑龙江大学图书馆在俄文图书联机编目实践成功后,又对俄文连续出版物联机编目工作进行了探索。针对著录内容的简化以及编号项和附注项、受控检索点、统一题名的著录等方面出现的普遍问题以及特殊出版物、连续出版物的出版变化和分类等方面的特殊问题,图书馆应统一俄文连续出版物数据库建设标准,进行俄文连续出版物编目工作的培训,指定专人定期维护已建成的数据库并做好编目人员队伍梯队建设。 相似文献

Riitta Alkula 《Information Retrieval》2001,4(3-4):195-208
The paper deals with linguistic processing and retrieval techniques in fulltext databases. Special attention is focused on the characteristics of highly inflectional languages, and how morphological structure of a language should be taken into account, when designing and developing information retrieval systems. Finnish is used as an example of a language, which has a more complicated inflectional structure than the English language. In the FULLTEXT project, natural language analysis modules for Finnish were incorporated into the commercial BASIS information retrieval system, which is based on inverted files and Boolean searching. Several test databases were produced, each using one or two Finnish morphological analysis programs. 相似文献

《Library Acquisitions: Practice & Theory #》1993,17(3):239-248
This article is based on a presentation given July 1, 1991, at the American Library Association's annual conference. It reports on an attempt to develop a CD-ROM price index modelled on the price indexes for serials and other materials produced under the aegis of ALA's Library Materials Price Index Committee and conforming to ANSI Standard Z39.20-1983. This proved to be an impossible task, primarily because of the inability to define a reliable unit of measurement for CD-ROM prices and the difficulty of tracking a sufficiently representative sample of the universe of CD-ROM titles purchased by libraries over the period from 1988–1991. However, the value of simply tracking the prices of a data sample without a base index year—a price inventory—was recognized by the Committee. The data gathered thus far were analyzed to show price trends by LC subject classification and publication types (monographs and serials). The 4.3% increase from 1989 to 1990 reflects the change from $1,783 to $1,860 in publication price for the average CD-ROM title. The evolution and stabilization of the CD-ROM publishing industry in the 1990s should support the eventual establishment of a CD-ROM price index, on which work continues. 相似文献

The article deals with serials publication and their acquisition and management of serials in libraries in the Great Socialist Peoples' Libyan Arab Jamahiriya. The introduction of printing and the earliest serials published in Arabic are detailed. Recent changes in government policies affecting general conditions in the country and expected changes in publication policies are discussed. Two lists containing serials published prior to 1975 and a third, consisting of current serials published under Green Book theories, are annexed. 相似文献

异构分布式信息检索系统整合研究 总被引：2，自引：0，他引：2
实现异构处理器、异构数据源之间的共建共享,必须对分布式检索系统的各个子系统进行整合。现有的技术对于实现具体的、个别的分布式检索系统的互操作虽然没有问题,但要建立普遍意义的互操作规范,尚有一定难度。数据/语义层的互操作仍是异构分布式信息检索系统整合的重点,相关研究仍需深入。 相似文献

This research offers information on the experience and educational backgrounds of serials workers and the amount of time per title utilized for serials processing functions as determined by onsite investigations of forty-eight libraries on nine major university campuses in 1975. In addition to leading to more intelligent staffing for serials processing, the data should be useful as a partial basis for budget requests, the future development of library staffing standards, and additional research in this important, but neglected, field. 相似文献

A "shorthand" code system which would uniquely identify serials could speed library operations of ordering and checking in serials, and could facilitate retrieval of information on a worldwide basis, through computerized methods. Each serial would be represented by a brief but unique combination of letters and/or numbers. Four different code systems have been developed. Two of these systems are in growing use today: the CODEN, which are composed of six capital letters having mnemonic significance, and the ISSN (International Standard Serial Numbers), which consist of two groups of four digits each. This annotated bibliography encompasses both the criteria for an ideal code and the development of the existing codes. 相似文献

A thesaurus has been developed to serve as the integrating unit for the computerized information storage and retrieval system of the Vision Information Center. The Center maintains records of information in the visual sciences which are available to the user in the forms of computer-assisted instruction, literature retrieval, and patient records. The numerical coding system used in the thesaurus permits seven levels of specificity; this specificity is required for depth of indexing, as well as to limit the retrieval to those bibliographic citations which are relevant to a highly specific search request. The flexible design of the thesaurus facilitates frequent revision and addition of new terminology. 相似文献

While some bibliographic information on serial publications is abundant and available from various sources, many librarians want extensive and accurate serials data which is convenient for searching. This article describes the genesis and development of a new serials database and subsequent serials reference work. 相似文献

The following paper examines current United Nations (UN) serial publishing practices. Using the series listed in the "Current Serials' list in the 1985 cumulated UNDOC: Current Index as the sample population, this study discusses UN serials in terns of their: (a) physical and intellectual formats, @) place of publication, c) frequency of publication, (d) survivability, indexing, and availability. The study concludes that UN serials follow a definite pattern of publication, despite apparent variability found in the UNDOC "Current Serials" list. The need for better bibliographic control for UN serials is also discussed. 相似文献

A project to recatalog and reclassify the book collection of the Bowman Gray School of Medicine Library utilizing the Magnetic Tape/Selectric Typwriter system for simultaneous catalog card production and computer stored data acquisition marks the beginning of eventual computerization of all library operations. A keyboard optical display system will be added by late 1970. Major input operations requiring the creation of "hard copy" will continue via the MTST system. Updating, editing and retrieval operations as well as input without hard copy production will be done through the "on-line" keyboard optical display system. Once the library's first data bank, the book catalog, has been established the computer may be consulted directly for library holdings from any optical display terminal throughout the medical center. Three basic information retrieval operations may be carried out through "on-line" optical display terminals. Output options include the reproduction of part or all of a given document, or the generation of statistical data, which are derived from two Acquisition Code lines. The creation of a central bibliographic record of Bowman Gray Faculty publications patterned after the cataloging program is presently under way. The cataloging and computer storage of serial holdings records will begin after completion of the reclassification project. All acquisitions added to the collection since October 1967 are computer-stored and fully retrievable. Reclassification of older titles will be completed in early 1971. 相似文献

一种面向语义的信息检索方法 总被引：1，自引：0，他引：1
传统的信息检索技术忽视了语义对检索过程的影响,这是造成查准率不高的一个重要原因.论文提出了一种面向语义的信息检索方法,该方法强调使用基于知网的语义处理技术实现对用户查询需求和目标文档的语义标注,使用基于知网的词汇链技术实现对文档特征词汇的过滤.一方面可以实现语义级别的检索匹配,另一方面可以降低大量无关词对检索结果的干扰.论文描述了一个实现该方法的信息检索系统SOIRS,并且利用该系统与传统检索系统做了对比实验.实验结果表明面向语义的信息检索方法在查准率方面要明显优于传统信息检索方法. 相似文献

Summary Numerous departments are involved in the serials processing chain, with functions becoming more inter-related in the online environment. At the University of Maryland at College Park, no one person or individual acted as a central clearing house for planning, implementing, or disseminating information about serials processing. This workshop examines function and process of a continuous quality improvement (CQI) team which studied the issues surrounding processing of serials, as well as the team's recommendations and their implementation. 相似文献

The serials and circulation phases of the data-processing system in use at the University of New Mexico Library of the Medical Sciences are described. The development of the programs is also reported. The serials program uses simple punched card equipment. The circulation program uses the IBM 357 Data Collection System and punched card data-processing equipment. 相似文献
