Reference Publication Year Spectroscopy (RPYS) and Multi-RPYS provide algorithmic approaches to reconstructing the intellectual histories of scientific fields. With this brief communication, we describe a technical advancement for developing research historiographies by introducing RPYS i/o, an online tool for performing standard RPYS and Multi-RPYS analyses interactively (at http://comins.leyd...

Referenced Publication Year Spectroscopy (RPYS) was recently introduced as a method to analyze the historical roots of research fields and groups or institutions. RPYS maps the distribution of the publication years of the cited references in a document set. In this study, we apply this methodology to the œuvre of an individual researcher on the occasion of a Festschrift for András Schubert’s 70...

Citation classics” are not only highly cited, but also cited during several decades. We test whether the peaks in the spectrograms generated by Reference Publication Years Spectroscopy (RPYS) indicate such long-term impact by comparing across RPYS for subsequent time intervals. Multi-RPYS enables us to distinguish between short-term citation peaks at the research front that decay within ten yea...

In this study, we analyzed the newly emerging research field of climate change in combination with tea production. We adapted a valid search query to cover the relevant literature as completely as possible and to exclude irrelevant literature. The search resulted in a publication set of 14 key papers dealing with the implications of climate change for tea production as well as 71 papers citing ...

We introduce the quantitative method named "reference publication year spectroscopy" (RPYS). With this method one can determine the historical roots of research fields and quantify their impact on current research. RPYS is based on the analysis of the frequency with which references are cited in the publications of a specific research field in terms of the publication years of these cited refer...

The use of artificial intelligence in paediatrics has vastly increased the last few years. Interestingly, no historical bibliometric study analysing knowledge development this specific paediatric field been performed yet, thus our aimed to close gap. References Publication Years Spectrography (RPYS), more precisely Cited Reference Explorer (CRE) software tool was employed achieve aim. We identi...

پژوهش حاضر با هدف شناسایی سیر تکاملی و تاریخی پژوهش‌های صورت گرفته در حوزه کاردرمانی با روش علم‌سنجی و استفاده از دو تکنیک جدید به نام‌های RPYSوRPYSCO که رویکردی مبتنی بر تاریخ علم دارند، انجام شده و به این صورت آثار و چهره‌های تأثیر‌گذار در روند تکامل این رشته از منظر داده‌های کتاب‌شناختی مورد تحلیل قرار گرفته است. جامعه این پژوهش را تعداد 7592 مقاله در حوزه کار‌درمانی که در بازه 20 ساله در نم...

We introduce a new tool – the CitedReferencesExplorer (CRExplorer, www.crexplorer.net) – which can be used to disambiguate and analyze the cited references (CRs) of a publication set downloaded from the Web of Science (WoS). The tool is especially suitable to identify those publications which have been frequently cited by the researchers in a field and thereby to study for example the historica...

Reference Publication Year Spectroscopy (RPYS) is a bibliometric method originally introduced to reveal the historical roots of research topics or fields. RPYS does not identify most highly cited papers publication set being studied (as usually done by analyses in evaluation), but instead it indicates frequently referenced publications – each within specific reference year. In this study, we pr...
