A review of the literature on citation impact indicators
Citation impact indicators nowadays play an important role in research
evaluation, and consequently these indicators have received a lot of attention
in the bibliometric and scientometric literature. This paper provides an
in-depth review of the literature on citation impact indicators. First, an
overview is given of the literature on bibliographic databases that can be used
to calculate citation impact indicators (Web of Science, Scopus, and Google
Scholar). Next, selected topics in the literature on citation impact indicators
are reviewed in detail. The first topic is the selection of publications and
citations to be included in the calculation of citation impact indicators. The
second topic is the normalization of citation impact indicators, in particular
normalization for field differences. Counting methods for dealing with
co-authored publications are the third topic, and citation impact indicators
for journals are the last topic. The paper concludes by offering some
recommendations for future research
A review of the characteristics of 108 author-level bibliometric indicators
An increasing demand for bibliometric assessment of individuals has led to a
growth of new bibliometric indicators as well as new variants or combinations
of established ones. The aim of this review is to contribute with objective
facts about the usefulness of bibliometric indicators of the effects of
publication activity at the individual level. This paper reviews 108 indicators
that can potentially be used to measure performance on the individual author
level, and examines the complexity of their calculations in relation to what
they are supposed to reflect and ease of end-user application.Comment: to be published in Scientometrics, 201
Applied Evaluative Informetrics: Part 1
This manuscript is a preprint version of Part 1 (General Introduction and
Synopsis) of the book Applied Evaluative Informetrics, to be published by
Springer in the summer of 2017. This book presents an introduction to the field
of applied evaluative informetrics, and is written for interested scholars and
students from all domains of science and scholarship. It sketches the field's
history, recent achievements, and its potential and limits. It explains the
notion of multi-dimensional research performance, and discusses the pros and
cons of 28 citation-, patent-, reputation- and altmetrics-based indicators. In
addition, it presents quantitative research assessment as an evaluation
science, and focuses on the role of extra-informetric factors in the
development of indicators, and on the policy context of their application. It
also discusses the way forward, both for users and for developers of
informetric tools.Comment: The posted version is a preprint (author copy) of Part 1 (General

How journal rankings can suppress interdisciplinary research. A comparison between Innovation Studies and Business & Management
This study provides quantitative evidence on how the use of journal rankings
can disadvantage interdisciplinary research in research evaluations. Using
publication and citation data, it compares the degree of interdisciplinarity
and the research performance of a number of Innovation Studies units with that
of leading Business & Management schools in the UK. On the basis of various
mappings and metrics, this study shows that: (i) Innovation Studies units are
consistently more interdisciplinary in their research than Business &
Management schools; (ii) the top journals in the Association of Business
Schools' rankings span a less diverse set of disciplines than lower-ranked
journals; (iii) this results in a more favourable assessment of the performance
of Business & Management schools, which are more disciplinary-focused. This
citation-based analysis challenges the journal ranking-based assessment. In
short, the investigation illustrates how ostensibly 'excellence-based' journal
rankings exhibit a systematic bias in favour of mono-disciplinary research. The
paper concludes with a discussion of implications of these phenomena, in
particular how the bias is likely to affect negatively the evaluation and
associated financial resourcing of interdisciplinary research organisations,
and may result in researchers becoming more compliant with disciplinary
authority over time.Comment: 41 pages, 10 figure
