In this article we analyze the performance of existing models to classify journal articles into disciplines from a predefined classification scheme (i.e., supervised learning), based on their abstract. The first part analyzes scenarios with ample labeled data, comparing the performance of the Support Vector Machine algorithm (SVM) combined with TF-IDF and with SPECTER embeddings (Cohan et al. SPECTER: Document-level representation learning using ...

This study compares publication pattern dynamics in the social sciences and humanities in five European countries. Three are Central and Eastern European countries that share a similar cultural and political heritage (the Czech Republic, Slovakia, and Poland). The other two are Flanders (Belgium) and Norway, representing Western Europe and the Nordics, respectively. We analysed 449,409 publications from 2013–2016 and found that, despite ...

On June 18, 2015, the New England Journal of Medicine published an article entitled "Permissive underfeeding of standard enteral feeding in critically ill adults", which reports the results of a study that examined the impact of prolonged nutritional energy restriction for critically ill patients. The study design was unique in the sense that patients in both groups received similar doses of protein during the intervention, while the non-protein ...

This study analyzes coauthorship patterns in the social sciences and humanities (SSH) for the period 2000 to 2010. The basis for the analysis is the Flemish Academic Bibliographic Database for the Social Sciences and Humanities (VABB-SHW), a comprehensive bibliographic database of peer-reviewed publications in the SSH by researchers affiliated with Flemish universities. Combining data on journal articles and book chapters, our findings indicate ...

We compare two supervised machine learning algorithms—Multinomial Naïve Bayes and Gradient Boosting—to classify social science articles using textual data. The high level of granularity of the classification scheme used and the possibility that multiple categories are assigned to a document make this task challenging. To collect the training data, we query three discipline specific thesauri to retrieve articles corresponding to specialties in ...

Even though bibliometric analyses often rely on different disciplinary classifications, it is not known to what extent the choice of classification influences bibliometric findings. Here we explore differences in the distribution of articles across disciplines using four different classifications. We use data on social sciences and humanities (SSH) journal articles from comprehensive bibliographic databases in Belgium (Flanders) and Norway ...
