    Example text

    Smith (1981) listed some basic assumptions about citation analysis: 1. 2. 3. 4. 5. A citation implies use of the cited document Citation reflects merit (or intellectual debt (Small, 2004)) Citations are usually made to the best possible and available work Cited, co-cited and bibliographically coupled documents are related in content All citations are equal These assumptions rather reflect the ideal of citation analysis than the reality of it, as some of the assumptions may not apply in every case.

    The h-index, although it counteracts against the shortcomings of JIFs, has been criticized, for instance, for the arbitrary choice of h as the number of significant publications (Bornmann & Leydesdorff, 2014). , Egghe, 2006; Burrell, 2007, 2013; Abramo, D’Angelo, & Viel, 2013; Ferrara & Romero, 2013; Schreiber, 2013). Vieira, Cabral, and Gomes (2014) tested a selection of different bibliometric indicators against peer evaluations and ranking of applicants to an academic position. Of the tested indicators a model including a modified h-index (the hnf-index, which normalizes for citation count and allows for fractional counting based on the number of co-authors of the publications) and the percentage of highly cited documents came close to peer evaluations and was to be preferred according to the authors, but even that should not substitute peer review.

    Webometric research has always been driven by the data available online. It could perhaps be said that webometrics have often looked at new data sources and asked, what type of data can we collect and analyze from here, or what kind of social science research questions can we answer by investigating this? Webometrics has also been heavily involved in the development of tools for both data collection and analysis (Thelwall & Wouters, 2005). In that sense, webometrics has always been at the cutting edge of new data sources and new research methods.
