This chapter focusses on the drivers for the advancement of mapping of science and the detection of topics as often applied in scientometrics. The chapter identifies three different drivers for this advancement: technological innovation resulting in increased computational power, the improved community detection approaches available today, and advancements in scientometrics itself with respect to the actual linking of documents through citations or lexical approaches. We will show that the main ...

It is difficult to imagine a world without science policy. Ever since Vannevar Bush published his seminal insights on the role of science in society, science policy has become deeply ingrained in public policy. Alongside this, the discipline of scientometrics developed. It started from library and information needs, helping the ever-growing scientific community to access, retrieve and disseminate its ever-increasing output. However, along the way, scientometrics developed into a powerful set of ...

In this chapter, we describe a scientometric assessment tool that was first introduced as early as the second half of the 1980s, but due to the high computational requirements at that time, the method fell undeservedly into oblivion. The method is called Characteristic Scores and Scales (CSS) and is aimed at providing a more detailed picture of citation impact, with particular regard to the high end of performance. More than two decades after its introduction, the method experienced a revival as...

A novel hashing algorithm is applied to match two prominent and important bibliographic databases at the paper level. In the literature, such tasks have been studied and conducted many times, but relying only on journal information due to massive volume of indexed publications. As a result of paper based match, missing or erroneous items can be completed from other source or the overlap can be measured more reliably. In this context, we focus on measuring the overlap between Clarivate Analytics ...

In this paper we study the effect of granularity on Characteristic Scores and Scales (CSS). Unlike the traditional indicators that are mostly based on means and quantiles, CSS require the reduction of the citation distributions collaboration of the underlying reference population to four states (classes) and thus higher a different level of granularity. While the question of the choice of granularity is at higher levels of aggregation usually not critical since countries and university have rath...

Abstract The concern about predominance of basic discovery research and lack of translation into clinical medicine, and segregation between these research communities, led the authors to study these research communities through mapping networks of publications and cross-references. Cardiovascular research from 1993 to 2013 was published in 565 journals, including 104 new journals. Only 50% were published in core cardiovascular journals, such as the Journal of the American College of Cardiology, ...

The introduction of textual analysis and the use of lexical similarities already proved an important asset in science mapping. Earlier research showed the added value of hybrid document networks over link-based ones through the reduction of the extreme sparseness. However, it was only after the application of Natural Language Processing and phrase extraction that networks purely based on lexical similarities could be used as input for topic detection in quantitative science studies. This study i...

Author name disambiguation plays a very important role in individual based bibliometric analysis and has suffered from lack of information. Therefore, some have tried to leverage external web sources to obtain additional evidence with success. However, the main problem is generally the high cost of extracting data from web pages due to their diverse designs. Considering this challenge, we employed ResearchGate (RG), a social network platform for scholars presenting their publication lists in a s...
