Research Activities

This section presents my main research activities that may help in understanding
the impact of my research. Assessing scientific quality is not an easy task andit is still source of debate among many scholars. One of the key issues on
this assessment is typically the publication record and associated bibliometricnumbers. However, there are many disciplines where other aspects of research
activity can be regarded as significant in terms of the impact on the community,
and that is frequently the case of Computer Science, the field were I belong. For
instance, developping a software tool that is widely used by the community andallows for further advances may well be more important than many publications
and yet it is seldom considered as a criterion as it is not easy to assess without
being involved in the concrete field of expertise. In my personal case I havedevelopped many software programs that are widely used by the community, likefor instance several R packages that have hundreds of monthly downloads. I havealso created and still mantain a free regression data set repository that is usedin most papers that test new regression algorithms whithin the machine learning
community. This type of contributions, although relevant and important in mypersonal opinion, are hardly reflected in any type of research bliblometrics (withthe exception of the data set repository whose citations are counted by Google
Scholar although not all papers that use these data sets, cite the repository).
In spite of the previously mentioned limitations I have collected some data
concerning bibliometric information related with my publications with the goalof helping in assessing the impact of this aspect of my research activities. The
inclusion of this information requires some clarifications. Bibliometric data
involves two main decisions: (i) whether to use it or not; and (ii) if yes, fromwhich source. The first decision is hard to escape - it is the norm nowadays toevaluate CVs based on these numbers. Unfortunately this process often leads tounwanted bad decisions. There is a growing awareness of the research communitythat these numbers may be seriously misleading, particularly in some disciplines(like Computer Science) where the publication culture is rather different fromother disciplines, for instance in the case of international conferences. While inmost disciplines works published in conferences are not subject to peer reviewing,that is not the case in CS where international conferences are always peer
reviewed and some are far more competitive than most journals. This leads toa clear bias on some of the frequently used bibliometric indices that frequently
disregard conferences. Regarding this issue of the bias and risk of misjudgmentof bibliometrics it may be interesting to point out several very interesting recent

10papers on this topic:• Diana Hicks, Paul Wouters, Ludo Waltman, Sarah de Rijcke & Ismael
Rafols.Bibliometrics: The Leiden Manifesto for research metrics. Nature
520, 429–431 (23 April 2015) doi:10.1038/520429a• Paula Stephan, Reinhilde Veugelers & Jian Wang. Reviewers are blinkeredby bibliometrics. Nature 544, 411–412 (27 April 2017) doi:10.1038/544411a• Rinze Benedictus, Frank Miedema & Mark W. J. Ferguson. Fewer numbers,
better science. Nature 538, 453–455 (27 October 2016) doi:10.1038/538453a
These and many other works have been trying to raise the awareness of thecommunity for the danger of these bibliometric-based decisions. Still, as this is
still the norm I will present some of these numbers with the list of publications
given below.
The second decision concerns the source of the bibliometric numbers. I haveconsidered 3 sources: Thomson ISI, Elsevier Scopus and Google Scholar. All ofthem have potential drawbacks. Still, the decision was to select Google Scholar(GS). This index overcomes some limitations the other indices have, particularly
for Computer Science, as it is clearly much more inclusive, although with anincreased risk of inflating numbers. A few examples of my personal CV provide
illustrations of the problems. My top cited publication is my book Data Mining
with R published by a major publishing house (CRC Press from Taylor andFrancis). For some reason that I cannot explain but most probably relatedwith financial issues between the companies involved, this book is not indexedby Scopus. So, a peer reviewed book by a major publisher is non-existent forthis widely used bibliometric index; (ii) one of my recent journal publications
is on ACM Computing Surveys, one of the top journals of Computer Science
according to the 2017 data from Thomson ISI impact factor. At some point intime (12/Dec/2017), according to Google Scholar (GS) this publication from2016 had 42 citations. According to Scopus this citation number was 20! If wecheck the concrete citations which is possible on GS we can observe that 6 ofthese were self-citations, so we can reduce this to 36, but this is still too far from
20. These and other similar effects lead to divergent values like the fact thatmy h-index according to Scopus is significantly lower than that reported in GS,
a very common phenomenon for computer science researchers as mentioned in[ˆ1]. Still, GS is not without problems either. For instance, the same book I’ve
mentioned above has two quite different editions currently, the second being morethan 150 pages longer, with the other pages having been significantly revised. In
spite of this GS insists in not considering these two books which obviously has
an impact on the bibliometrics (I’ve inserted it manually but citations are notbeing counted by GS).
[ˆ1] - Judit Bar-Ilan. Which h-index? — A comparison of WoS, Scopus andGoogle Scholar. Scientometrics, Volume 74, Issue 2, pp. 257–271.
Summarizing, I have decided to include bibliometric data from Google Scholar,
even-though I’m well aware that this is a source of debate but my decision was
11essentially guided by completeness criteria both in terms of computer science ingeneral and in my particular case. Moreover, in order to try to provide more
information on the quality of the peer-reviewed conference papers, I have added
the CORE rank of the respective conferences. CORE is a widely used source of
information on the computer science conferences reputation. It is used wordwide
by many funding agencies and universities where the specificities of the computerscience field have been recognised. This austrolasian association provides a rankfor international conferences using a scale from A* till Unranked. Further details
on the criteria and meaning of this classification schema can be obtained here.
