以豆瓣网和中国国家图书馆为案例的网上书目推荐系统研究

现有网上书目推荐系统根据应用服务理念的不同可以分为Web2．0型和传统型,根据其使用的过滤技术可以分为非个性化推荐、基于产品属性的推荐、基于相关用户的推荐和基于用户知识结构的推荐。书目推荐的开展应当遵循针对性、可行性、时效性这三个原则。本文通过对豆瓣网和中国国家图书馆的网上书目推荐服务的调查,从有用性、易用性、满意度、可找到性、普及性和可靠性六个方面对它们进行了比较,概括了传统型网上书目推荐系统的优势和改进意见。     

On the problem of determining a citation index of publications by Kazakh scientists

This paper discusses the evaluation of scientific activity with the help of some scientometric indices, in particular, a citation index. The information massif of the bibliographic database of citations to domestic publications of Kazakh authors is statistically described.     

Key issues of the development of the information infrastructure and information support of innovation activities

We consider some issues of the development of the national information infrastructure in the field of innovation, including a national system of accounting for the results of scientific and technical activities (RSTA) and a national new-generation research computer network (NNGRCN). The current state of the national system of scientific and technical information and its resources for information support of innovation processes are analyzed. In the context of further development of the Commonwealth of Independent States (CIS), we propose a Conception of scientific and technical support for programs and projects of NIS member-states in the field of innovation, making it possible to incorporate the existing innovation-oriented information resources into a joint distributed integrated information system as well as to create new information resources and technologies.     

基于粗糙―模糊集的Web信息检索改进模型

针对传统信息检索模型对不确定性知识处理的不足,提出一种基于粗糙集的信息检索改进模型,并以粗糙集技术为支撑,结合模糊集合理论,对查询进行泛化以提高查询性能,同时给出该模型的关键实现算法及性能评估方法。该模型能够提高信息检索的效率,具有较高的理论及应用价值。     

Enhancing reference services with the support of your colleagues

The expertise of colleagues and experience gained through professional organizations is an overlooked resource for adding value to reference service. Collegial networks must be nurtured. They deserve the support and investment of the institution.     

Analysis of the use of reference services in an academic health sciences library

In 1991, the Reference and Information Services staff of the Alfred Taubman Medical Library at the University of Michigan gathered data on the use of the reference desk, including the frequency and types of assistance requested by different user groups throughout the year. Recommendations based on the results of this study led to improved service as well as more efficient use of staff resources.     

The literature of women and the acquired immunodeficiency syndrome (AIDS): implications for collection development and information retrieval

The purpose of the study was to identify the pattern of publication about women and AIDS in scientific journals. Bradford zones were identified in each of six databases. The study determined that journal scatter for this subset of AIDS literature differed from the scatter in the general literature; further, the information indexed in the six electronic sources demonstrated little overlap. Consequently, key journal and newsletter titles identified by this study should form the core of any collection focusing on women and AIDS. The assurance of quality patient care management demands that librarians consult multiple resources for information retrieval that can assist health care providers, patients, and caregivers to enhance quality of life as well as to provide optimum care.
