Editorial: Research beyond our borders

Abstract

Translate Article

This first issue of SACJ in 2023 includes three papers from researchers outside South Africa: one from our neighbours in Namibia and two from Ukraine.The first paper from Namibia by Shapopi, Limbo and Backes describes the operation and running of Namibia's first high performance computer, how this experience has developed human capacity, and how the service is supporting scientific research.The paper is published in the form of a 'Communication', rather than a research paper.Communications in SACJ are publications of ideas or experiences that are deemed by the editor-in-chief to be of interest to readers.Although contributions of this category are not peer reviewed and hence would not qualify for government subsidy in the South African context, they still follow the usual copy-editing and production editing processes and are allocated a unique persistent DOI like regular research papers.Similar to Communications, Viewpoints are publications of research-in-progress that are not peer reviewed.In this issue, we have two articles published as Viewpoints from the Glushkov Institute of Cybernetics of the National Academy of Sciences of Ukraine.Since Russia's invasion of Ukraine in 2022, the work of Ukrainian researchers has become very challenging due to the large-scale decrease in funding for research projects.In addition, many researchers were mobilised into the ranks of the armed forces and those who are keeping research going in cities such as Kyiv have to contend with the unpredictability and destruction of ongoing rocket attacks.We are therefore happy to support these researchers in a small way by disseminating their work.Figure 1 provides a glimpse into the research lab in Kyiv of the authors who contributed to this issue.Both articles from Ukraine are related to ontologies.The first paper by Malakhov, Petrenko and Cohn describes the architectural and structural organisation of an ontology-related system for processing repositories of scientific publications.The second paper by Litvin, Palagin, Kaverinsky and Malakhov describes an approach for the automated creation of ontologies from natural language text and provides a software implementation parameterised for the Ukrainian language.We hope these articles will be of interest to researchers in South Africa
