This study presents a comparative analysis between two scientific document classification systems. The first system employs the Scopus journal-based assignment method, adapted to a fractional model, while the second system uses the U1-F-0.8 classification, an item-by-item system based on reclassified references according to the origin of the citers...

A reference-based classification system for individual Scopus publications is presented which takes into account the categories of the papers citing those references instead of the journals in which those cited papers are published. It supports multiple assignments of up to 5 categories within the Scopus ASJC structure, but eliminates the Multidisc...

This paper presents and evaluates a set of methods to classify individual Scopus publications using their references back to the second generation, where each publication can be assigned fractionally into up to five ASJC (All Science Journal Classifications) categories, excluding the Multidisciplinary area and the miscellaneous categories. Based on...

In this paper, we present the results of the first global ranking that assesses the status and evolution of the media according to their digital reputation. We analyzed 4,541 general information digital newspapers, both legacy and native, published in 200 countries and in more than 80 languages. Methodologically, we applied a new Digital Reputation...

An indicator to measure disruption has recently been proposed (Funk & Owen-Smith, 2017; Wu, Wang, & Evans, 2019) which has given rise to a large number of variants (Bornmann et al., 2020). In this work we are going to focus on the original indicator DI and the one that seems to have a better performance DI5 (Bornmann and Tekles, 2021; Bittmann et a...

Purpose This study aimed to examine the similarities and differences between the ability to analyze the environment and exploit new knowledge (absorptive capacity) and the skills to generate value from innovation (appropriation). These fields have similar origins and are sometimes confused by practitioners and academics. Design/methodology/approac...

Despite the increasing number of data visualization authoring systems in recent years, it remains a challenge to simultaneously achieve high expressive power and ease of use in a single tool. In this paper we present SCImago Graphica, a no-code tool which allows the creation of complex visualizations by simple drag-and-drop interactions. Users bind...

This paper presents a large-scale document-level comparison of two major bibliographic data sources: Scopus and Dimensions. The focus is on the differences in their coverage of documents at two levels of aggregation: by country and by institution. The main goal is to analyze whether Dimensions offers as good new opportunities for bibliometric analy...

Предлагается действующее определение степени журнала национальной ориентации на основе географического распространения его публикующихся или цитирующих автор...

In Scopus there are four times more documents in first-quartile publications than in fourth-quartile ones. Publishers intend to adjust the editorial supply to the demand from authors, which seems to focus primarily on Q1 publications. Since 44% of the papers are concentrated in Q1 journals, papers published in journals in this quartile will be more...

Scientific research in the communication field has experienced great growth in recent years.

It is very popular in bibliometrics to present results on institutions not only as tabular lists, but also on maps (see, for example, the Leiden Ranking). However, the problem with these visualisations is that institutions are frequently spatially clustered in larger cities whereby institutions are positioned one above the other. In this Brief Comm...
