“…Such data sets may facilitate access to the right information. Moreover, the use of massive data sets crossed with robust data analyses may foster multidisciplinary perspectives, raising new questions and providing new answers [27][28][29]. Classification techniques can be used to go through the large volume of references and allow researchers to save time on this part of their research.…”

UNSTRUCTURED In these trying times, we developed an R package to simplify the workflow of interested researchers, with multidisciplinarity in mind. With more than 28,000 medical references, this package is among the largest ones about the medical references on coronaviruses. It is also the only one of this size - to the best of our knowledge - to be built in the R language. This package could be of interest to epidemiologists, researchers in scientometrics, biostatisticians, as well as data scientists broadly defined. This package collects references from PubMed and organize the data in a dataframe. Then, we built functions to sort through the collection of references. Researchers can also integrate the data in their own pipeline and implement in R their own code libraries. We provide a short use case in this article based on a bibliometric analysis of the references made available by this package.

Purpose Cross-border e-commerce in China has been booming in recent years. This paper aims to study pricing in Chinese cross-border e-commerce companies and focuses on the baby food market, which is simply examined as a case study to highlight broader implications. In this intensely competitive sector, the biggest challenge faced by such companies is ensuring that they are in a position to be able set prices in the short-term to maximize their competitive advantage and profitability. The study of pricing will help management to make correct operational decisions. Design/methodology/approach This study utilizes transaction data, which were obtained from the Taobao e-commerce platform. Taobao is the largest e-commerce retail platform in the world. We analyzed factors, including business models, homogeneity, reputation ratings and sales volumes, which may affect pricing. Findings This study found that consumers in the baby food sector of Chinese cross-border e-commerce are not price-sensitive. Consumers are reputation-rating-sensitive. The reputation ratings of sellers affect the price dispersion in e-commerce markets. The Core Price Dispersion Rate Model not only considers the prices but also takes sales volumes into account in the calculations. Finally, based on Gaussian processes, a model was developed for price forecasting in the area of cross-border e-commerce. The experimental results show that the proposed method is highly valuable for price forecasting. Originality/value This study provides a novel understanding of the baby food sector in the Chinese cross-border e-commerce market by examining the business model, price dispersion, reputation rating and correlation between the reputation of sellers, prices and sales volume. Furthermore, a model for price forecasting is proposed.

“…In any case, it would be interesting to demonstrate this hierarchy with a competitive keystone-based market structure at the top, then a monopolistic keystone-based market structure, and then a no-keystone-based pure and perfect competition market structure. From an empirical perspective, it would be interesting to look into the use of big data to go this route (Warin and Troadec 2016;Warin and Leiter 2012).…”
