开放资源互操作协议OAI研究 总被引：9，自引：0，他引：9
随着数字图书馆的发展,各种资源间的互操作性也变得越来越重要,人们也一直致力于对分布式资源进行统一检索的开发。要实现这一目标,归纳起来有三种方式:代理模式,即通过检索代理对不同的目标源分别检索,然后对检索结果统一处理;联邦检索模式,即各个目标源严格遵守统一标准或协议从而实现底层的跨库检索;采集模式,即通过元数据采集协议将分布的元数据集中提供检索。本文对这三种模式进行了对比介绍,并对国际上应用越来越广泛的 OAI 元数据互操作机制及应用进行了详细介绍和讨论。 相似文献

The rapid growth of the Web has increased the difficulty of finding the information that can address the users’ information needs. A number of recommendation approaches have been developed to tackle this problem. The increase in the number of data providers has necessitated the development of multi-publisher recommender systems; systems that include more than one item/data provider. In such environments, preserving the privacy of both publishers and subscribers is a key and challenging point. In this paper, we propose a multi-publisher framework for recommender systems based on a client–server architecture, which preserves the privacy of both data providers and subscribers. We develop our framework as a content-based filtering system using the statistical language modeling framework. We also introduce AUTO, a simple yet effective threshold optimization algorithm, to find a dissemination threshold for making acceptance and rejection decisions for new published documents. We further propose a language model sketching technique to reduce the network traffic between servers and clients in the proposed framework. Extensive experiments using the TREC-9 Filtering Track and the CLEF 2008-09 INFILE Track collections indicate the effectiveness of the proposed models in both single- and multi-publisher settings. 相似文献

E-government evaluation: a framework and case study 总被引：2，自引：0，他引：2
The importance of measuring the performance of e-government cannot be overemphasized. In this paper, a flexible framework is suggested to choose an appropriate strategy to measure the tangible and intangible benefits of e-government. An Indian case study of NDMC (New Delhi Municipal Corporation) has been taken up for analysis and placement into the framework. The results obtained suggest that to have a proper evaluation of tangible and intangible benefits of e-government, the projects should be in a mature stage with proper information systems in place. All of the e-government projects in India are still in a nascent stage; hence, proper information flow for calculating ‘return on e-government’ considering tangible and intangible benefits cannot be fully ascertained. 相似文献

A general model of performance and quality for one-stop e-Government service offerings 总被引：2，自引：2，他引：2
This paper introduces a framework and methodology for establishing indicators and metrics in order to assess the quality and performance of one-stop e-Government service offerings. The set of quality and performance indicators and metrics proposed has been derived in an outcomes assessment approach, based on the perspectives of e-Government service providers and end-users and following a goal-question-metric line of work that departs from some key quality and performance benefits. A methodology that employs the proposed framework to set improvement targets according to alternative scenarios is presented, and a strategy is elaborated for analyzing root causes of potential quality and performance shortcomings and undertaking appropriate countermeasures. Some results of application in a real case study, in the context of an EU-funded R&D project, are also provided. Finally, recommendations are given about usefulness of the proposed approach for e-Government service providers, as well as policy and decision-makers, and directions of future work are discussed in order to enhance the conceptual coverage of this approach, while at the same time not compromising its simplicity of application and generality of purpose. 相似文献

An ethnographic study was designed to understand the nature and the role of public library service in a specific context. Using mostly the theoretical frameworks of Pierre Bourdieu and Anthony Giddens, the study provides an analysis of the two basic systems of meaning that service providers bring to their interaction with users. Service is conceptualized as a set of organizational processes involving the production, distribution, control, and consumption of various types of resources. Research findings reveal that service providers experience various types of ambiguities and dilemmas stemming from the broad mission of the public library. Similar tensions regarding the nature of the institution were found in the social environment and at the institutional level. The study offers a framework for studying service practices in relation to social and historical issues. 相似文献

Health education for Somali Bantu refugees via home visits 总被引：1，自引：1，他引：0
Eisenhauer ER Mosher EC Lamson KS Wolf HA Schwartz DG 《Health information and libraries journal》2012,29(2):152-161
Background: Somali Bantu refugees, with unique health information needs, created challenges for health and social service providers. Objectives: A service innovation was developed (i) to raise awareness, especially among local health and social service providers, about the Bantu refugees’ presence in the community, their culture, and their information needs and (ii) to deliver needed health information, emphasizing child health, to the Bantu mothers in their homes. Methods: The project consisted of: (i) a community conference targeting local health and social service providers, describing the refugees’ presence in the community, their culture, and information needs. (ii) Focus groups conducted with members of the Bantu population elicited additional information needs. (iii) Curriculum was developed based on identified needs, and (iv) the curriculum was delivered to the refugees in their homes. A clinical informationist and MP3 technology enhanced the project. Findings: Conference attendees’ evaluation responses indicated improved understanding of Bantu culture. Focus groups’ identification of health information needs provided a framework for the health education curriculum. A project website made educational materials available to other healthcare providers. Conclusions: The project raised awareness of the Bantus’ presence, culture, and information needs. Identification of other unmet needs demonstrated that additional support for refugees is required. 相似文献

In a world characterized by the use of rapidly advancing technology, public libraries are championing the rights of the individual to equitable public access to information provided over the Internet. But beyond general connectivity, libraries are also facilitating citizens' access to networked community information (CI) by actively linking users with relevant sites, by hosting pages for other service providers, and by participating in community networking initiatives. For individuals, the availability of networked CI means that they can access it at anytime and from any place, including the home, office, and public library. This article reviews recent trends in the networked CI literature, including public library involvement, and then discusses a major study underway for which multiple methods are being used to collect data from users, librarians, and service providers in three states. Particular attention is given to explaining the use of theory specification to apply Dervin's sense-making framework in an online environment. 相似文献

In 2005, SUSHI became the latest buzzword in the library community. This article (and this kind of SUSHI) refers to usage data, not raw fish. The growth of online collections has resulted in libraries demanding that publishers provide detailed usage data to allow them to better manage their collections and purchases. The Project COUNTER Code of Practice was created in response to this need; however, it did not address the painstaking task of collection and management of the usage data. SUSHI is a new protocol developed to allow for automated retrieval of COUNTER usage reports from publishers and other content providers. 相似文献
