On the « persistency » of scientific publications: introducing an h-index for journals

Author : Roberto Piazza

What do we really mean by a « good » scientific journal? Do we care more about the short-time impact of our papers, or about the chance that they will still bhe read and cited on the long run?

Here I show that, by regarding a journal as a « virtual scientist » that can be attributed a time-dependent Hirsch h-index, we can introduce a parameter that, arguably, better captures the « persistency » of a scientific publication. Curiously, however, this parameter seems to depend above all on the « thickness » of a journal.

Web Services for Bibliometrics

Institutional repositories have spread in universities where they provide services for recording, distributing, and preserving the institution’s intellectual output. When the Lausanne « academic server », named SERVAL, was launched at the end of 2008, the Faculty of Biology and Medicine addressed from the outset the issue of quality of metadata. Accuracy is fundamental since research funds are allocated on the basis of the statistics and indicators provided by the repository. The Head of faculty also charged the medical library to explore different ways to measure and assess the research output. The first step for the Lausanne university medical library was to implement the PubMed and the Web of Science web services to easily extract clean bibliographic information from the databases directly into the repository.

Now the medical library is testing other web services (from CrossRef, Web of Science, etc.) to generate quantitative data on research impact mainly. The approach is essentially based on citation linking. Although the utility of citation and bibliometric evaluation is still debated, the most prevalent output measures used for research evaluation are still those based on citation analysis. Even when a new scientific evaluation indicator is proposed, such as h-index, we can always see its link with citation. Additionally, the results of a new indicator are often compared with citation analysis. The presentation will review the web services which might be used in institutional repositories to collect and aggregate citation information for the researchers’ publications.

Measuring the visibility of the University’s scientific production using GoogleScholar, « Publish or Perish » software and Scientometrics

Open access to scientific information through institutional digital repositories presents today’s world information environment and the transformations imposed by information society.

The first Romanian institutional repository was implemented at Transilvania University of Brasov. As part of the undertaken research, the visibility and the impact of the university’s scientific production was measured using the scientific methods of scientometry, as a fundamental instrument for determining the international value of an university as well as for the statistical evaluation of scientific research results.

The results showed that an open access institutional repository would significantly add to the visibility of the university’s scientific production.In this article we define the scientific production and productivity and present the main indicators for the measurement of the scientific activity.

The impact of the research is analyzed and measured through scientometric indicators. The analysis of the citations represents a scientometric indicator for the evaluation of the scientific researches.

Through the number of citations we can analyse the quality of the scientific information. Google Scholar was used as a scientometric database which can be consulted free of charge on the Internet and which indexes academic papers from institutional repositories, identifying also the referenced citations.

The free “Publish or Perish” software can be used as an analysis instrument for the impact of the research, by analysing the citations through the h-index.

We present the methodology and the results of an exploratory study made at the Transilvania University of Brasov regarding the h-index of the academic staff. H-index was calculated by using “Publish or Perish” software, comparing the number of ISI indexed published articles and the number of citations from “ISI Web of Science”.

Using “Publish or Perish”, we calculated h-index, g-index, hc-index and HI norm. We analyzed the research performances achieved by Brasov academic community in 2008, as realised in their annual evaluation -number of papers, books, research contracts, etc- by comparing the four indexes of those 60 professors with the best results.

We will present correlation indicators and the importance of open access for increasing the impact of scientific research by using institutional repositories.
