An analysis of backlink counts and Web Impact Factorsfor Chinese university websites

This article aims to study the total backlink counts, external backlink counts and the Web Impact Factors (WIFs) for Chinese university websites. By studying whether the backlink counts and WIFs of websites associate with the comprehensive ratings and the research ratings for Chinese universities, the article demonstrates that the external backlink count can be a better evaluation measure for university websites than WIF. The study also investigated issues about data collection by using different search engines. It shows that data collected by Alta Vista are more stable than AllTheWeb.

Scientific research competitiveness of world universities in computer science

This article evaluates the scientific research competitiveness of world universities in computer science. The data source is the Essential Science Indicator (ESI) database with a time span of more than 10 years, from 01/01/1996 to 08/31/2006. We establish a hierarchical indicator system including four primary indicators which consist of scientific research production, influence, innovation and development and six secondary indicators which consist of the number of papers, total citations, highly cited papers, hot papers, average citations per paper and the ration of highly cited papers to papers. Then we assign them with proper weights. Based on these, we obtain the rankings of university and country/territory competitiveness in computer science. We hope this paper can contribute to the further study in the evaluation of a certain subject or a whole university.

An empirical study on the utilization of web academic resources in humanities and social sciences based on web citations

In this era of a rapid change in the way people finding and using information resources, despite that the academic communication and using patterns for people in the traditional print environment have been studied for many years, the Internet media presents a new and relatively unexplored area for such study. In this article, we explored the distribution and utilization of web recourses in humanities and social sciences based on web citations. We collected 1,421,731 citations listed in 148,172 articles from 493 journals published during the period of 2006–2007 in the CSSCI, which resulted in 44,973 web citations. We counted the amount and types of web resources used in various disciplines, analyzed the URLs frequency from the host-level, fitted the frequency distribution into the regression models with SPSS, and perform the disciplines coupling analysis based on the web citations. We found out that: (a) The distributions of web citations by years or by websites and webpage types are selective and regular; (b) Great disparity exists among various disciplines in terms of using web information, and the high-frequency websites; (c) The frequency distribution of web citations is similar to the Garfield’s citation distribution curve; (d) Some relationships between disciplines are detected, based on the utilization of web information.

Research on the cross-citation relationship of core authors in scientometrics

Generally speaking, citation relationship among authors can be divided into 3 types: co-citation, coupling and cross-citation. Since author co-citation analysis was first introduced in 1982, it has been widely applied to study discipline structure, research state and research trends. Afterwards, conception of author bibliographic-coupling analysis was put forward and related empirical studies provided a method for mapping active authors in a research field for a more realistic picture of the current state of its research activities. Additionally, if one of author A’s papers has a citation from one of author B’s, there is cross-citation relationship between A and B. However, studies based on author cross-citation relationship mainly describe citation behaviors themselves using citation identity and citation image; they rarely involve any implicit knowledge communication, author research correlation or discovering academic communities. Author cross-citation analysis infers to both citing and cited phenomenon, which can be roughly correspond to citation identity and citation image. The study will further explore the author cross-citation relationship with core authors in scientometrics field as study object in order to provide reference for development of scientometrics field and in-depth application of citation analysis.

An approach to improve the indicator weights of scientific and technological competitiveness evaluation of Chinese universities

As indicator weights obtaining is often difficult in all types of evaluation, this paper describes an approach to improve the indicator weights of scientific and technological competitiveness evaluation of Chinese universities. As a public institution funded by Chinese government, the research center for Chinese science evaluation of Wuhan University has completed five annual evaluations for the scientific and technological competitiveness of Chinese universities since 2005, whose abundant and reliable data motivated us to try to improve the weights obtained by the AHP (analytical hierarchy process). Based on these data, we calculated the objective weights of the indicator using the representative mathematical methods of the least square and the variation coefficient. As the weights of AHP can be influenced by the knowledge, experience and preference of experts and the calculated objective weights neglect the subjective judgement information, we integrated the subjective and objective weights by respectively using the additive and multiplicative model to reflect both the subjective considerations of experts and the objective information, and obtained three kinds of integrative weights. Finally, we selected the integrative weights of multiplicative model as the best weights by comparing and analyzing the evaluation results in 2005 and 2009 of each kind of weights. The results show that the evaluation effect of the weights of multiplicative model is indeed the best for all types of Chinese universities among these kinds of weights, and the experts and university principals enquired also basically reached a consensus on the university rankings of the integrative weights of multiplicative model.

New exploratory work of evaluating a researcher’s output

SCI has been popular all over the world since it was published by Garfield in 1963. Researches on evaluating a researcher’s output with SCI have always been continuous. In recent years, a great breakthrough has been made since the h-index was put forward in 2005. In this paper, we also advance a new method — Paper Quality Index (PQI) to evaluate the output of a researcher. The main purpose of our method is to solve two problems that consist in the method of h-index: one is that the h-index can’t compare the outputs of researchers in different fields; the other is that it is unsuitable for evaluating the outputs of young researchers. A simple mathematical expression is constructed to eliminate the difference of citation among different fields and makes the evaluation of short-term outputs of researchers possible.

An exploratory study on substantive co-link analysis: A modification to total co-link analysis

Since the term “co-link” was put forward, many scholars have done exploratory investigations to prove the applicability and validity of co-link analysis used in mapping internet structure and mining relationships among internet colonies. All of these studies are based on the whole links in the web called “total co-link analysis”. However, there are both substantive and non-substantive links in the web, and the number of the latter outweights that of the former, which makes the preconditions of total co-link analysis untenable. In this paper, we present “substantive co-link analysis”, and believe it is more sound and valid than “total co-link analysis”. Then exploratory investigations on both total and substantive co-link analysis are carried out with the sample of 20 academic blogs on Library and Information Science, the results of which testify our assumption that “substantive co-link analysis” is more efficient and reasonable than “total co-link analysis”.

Digital Library System Integration Model Construction Based on Semantic Web Service

At the basis of analyzing the basic structure and current application of the Semantic Web Service, we built digital library system integration model based on Semantic Web Service. Detailing the realization process of the entire model, the paper focuses on the two main modules: the main module of digital library system integration processing and the main module of digital library system function query. The model is the effective integration of digital library system resources to create a centralized, united digital library system, and to make the query up to semantic level. It enhances the overall operation and service performance of digital libraries.

Analysis on research activity and impact of authors in Chinese information science based on citation relationship

– The purpose of this paper is to further explore the co-citation and bibliographic-coupling relationship among the core authors in the field of Chinese information science (IS), to expose research activity and author impact, and to make induction analyses about Chinese IS research patterns and theme evolution. , – The research data include 8,567 papers and 70,947 cited articles in the IS field indexed by Chinese Social Sciences Citation Index from 2000 to 2009. Author co-citation analysis, author bibliographic-coupling analysis, social network analysis, and factor analysis were combined to explore co-citation and bibliographic-coupling relationships and to identify research groups and subjects. , – Scholars with greatest impact are different from the most active scholars of Chinese IS; there is no uniform impact pattern forming since authors’ impact subjects are scattered and not steady; while authors’ research activities present higher independence and concentration, there is still no steady research pattern due to no deep research existing. Furthermore, Chinese IS studies can be delineated by: foundation or extension. The research subjects of these two parts, as well as their corresponding/contributing authors, are different under different views. The general research status of core authors is concentrated, while their impact is broad. , – The combined use of some related methods could enrich the development and methodology research of the discipline, and the results establish a reference point on the development of IS research.

The Credibility of Enterprise’s Website and Its Evaluation in the Customer’s Perspective

The credibility of website is a sort of psychological feeling, in other words, a sense of trust and its intensity towards the enterprise’s website produced by the customers from individual or collective perspective. The credibility of website has become a decisive factor for the website’s survival and an important driving force of promotion and market expansion. Currently, the credibility of website is still at a low level. There are many factors affecting the customer’s assessment of the credibility of enterprise’s website. According to the website’s structure and function modules, the evaluation indicator framework for the credibility of enterprise’s website is divided into three level indicators, respectively: the credibility of website structure, the credibility of website service, and the credibility of E-marketing. There are a number of second-level indicators under each level indicator. Since the credibility of website is one kind of subjective psychology feeling, it can use the multi-level fuzzy comprehensive evaluation based on the expert consultation and the customer questionnaire survey to evaluate the credibility of enterprise’s website. This paper finally takes a gift company website as a case study, and has carried out an evaluation of its credibility. As the evaluation of ordinary customer is obviously different from that of the expert, together with the shortcomings inherent in questionnaire survey, the evaluation of credibility of website based on customer perspective may result in deviation sometimes.
