We construct a meta-ranking of 277 economics journals based on 22 different rankings. The ranking incorporates bibliometric indicators from four different databases (Web of Science, Scopus, Google Scholar, and RePEc). We account for the different scaling of the bibliometric indicators by standardizing each ranking score. We run a principal component analysis to assign weights to each ranking. In our meta-ranking, the top five journals are given by: Quarterly Journal of Economics, Journal of Financial Economics, Journal of Economic Literature (JEL), Journal of Finance, and Econometrica. Additionally, leaving out the JEL as a survey journal and the finance journals in our top 10 list we confirm the perceived top five journals in the economics profession. 相似文献

A web-based system architecture for ontology-based data integration in the domain of IT benchmarking
In the domain of IT benchmarking (ITBM), a variety of data and information are collected. Although these data serve as the basis for business analyses, no unified semantic representation of such data yet exists. Consequently, data analysis across different distributed data sets and different benchmarks is almost impossible. This paper presents a system architecture and prototypical implementation for an integrated data management of distributed databases based on a domain-specific ontology. To preserve the semantic meaning of the data, the ITBM ontology is linked to data sources and functions as the central concept for database access. Thus, additional databases can be integrated by linking them to this domain-specific ontology and are directly available for further business analyses. Moreover, the web-based system supports the process of mapping ontology concepts to external databases by introducing a semi-automatic mapping recommender and by visualizing possible mapping candidates. The system also provides a natural language interface to easily query linked databases. The expected result of this ontology-based approach of knowledge representation and data access is an increase in knowledge and data sharing in this domain, which will enhance existing business analysis methods. 相似文献

The implementation of Internet technologies has led to e-Manufacturing technologies becoming more widely used and to the development of tools for compiling, transforming and synchronising manufacturing data through the Web. In this context, a potential area for development is the extension of virtual manufacturing to performance measurement (PM) processes, a critical area for decision making and implementing improvement actions in manufacturing. This paper proposes a PM information framework to integrate decision support systems in e-Manufacturing. Specifically, the proposed framework offers a homogeneous PM information exchange model that can be applied through decision support in e-Manufacturing environment. Its application improves the necessary interoperability in decision-making data processing tasks. It comprises three sub-systems: a data model, a PM information platform and PM-Web services architecture. A practical example of data exchange for measurement processes in the area of equipment maintenance is shown to demonstrate the utility of the model. 相似文献

The Hong Kong Disneyland will be open in 2005 and the theme park is very likely to have an official web site. In order to determine the nature of a model/ideal official web site that would serve the promotional purpose, this study is conducted with two objectives. First, the study makes an attempt to understand the information types that the target markets, namely local Hong Kong residents, Western visitors and Chinese visitors, would like to have on the future Hong Kong Disney web site. Secondly, this research examines whether e‐ticketing is feasible for the web site. Using a questionnaire and a convenience sampling method, 198 responses were received. Empirical results indicate that the respondents all agreed that the suggested attributes should be listed in the web site. In addition, no significant difference was found among different groups of respondents on homepage information. However, significant differences were found among the interviewees’ views regarding products/services information, and ticketing information. To communicate effectively, the adoption of EDI (Electronic Data Interchange) is recommended in a value‐chain system for achieving successful e‐commerce. 相似文献

People from around the world are bringing together a variety of information technologies—devices, services, applications, networks, and information—to create personal information systems. This emerging phenomenon is enabled by a convergence of inexpensive, powerful, and ubiquitous devices and applications connected through global networks, motivated by an open ideology and enacted by ‘prosuming’ users. This article examines the phenomenon of the user-generated information system (UGIS) to better understand its origins and thereby describe its nature. A formal definition of UGIS is developed, and its components described. A model of the ideological and technical forces that contribute to the changing role of the user as information system creator, and to the emergence of this capability and issues, is introduced. Implications for managers are discussed. 相似文献
