This paper presents the architecture for the development of web applications for exploring semantic knowledge graphs through parameterized interactive visualizations. The web interface and the interactive parameterized visualizations, in the form of a computational book, provide a way in which knowledge graphs can be explored. An important part of...

... change of entities or SPARQL endpoints can be done in the cells that are directly in the computational book. Figure 2 shows the cells where the code can be changed, and the parameters of the visualization, Figure 3 shows the TreeMap which is one of the visualisations in this use case. This way, users can discover new data from knowledge graphs. ...

Data science collaboration is problematic when access to operational data or models from outside the data-holding organisation is prohibited, for a variety of legal, security, ethical, or practical reasons. There are significant data privacy challenges when performing collaborative data science work against such restricted data. In this paper we de...

The reproducibility of code and the whole environment in which that code needs to be executed takes up much of the time of software engineers, computer scientists, and anyone who writes code. There are several reasons why we can not get the same results if the original data is available to us. This may be because the environment is not configured the same way as the source code author, we do not have enough knowledge of the technology used, poorly written documentation , lack of documentation, different versions of libraries, tools, development frameworks, mistakes made by one who wants to reproduce the code or there are errors in the code or errors that occurred after a certain period of time. In this paper, we introduce a new system for reproducible coding environments called Dohrnii, as a cloud-based solution. The main purpose is to save the time lost when we want to reproduce the results of a project for the first time. Every Dohrnii environment contains a video, description, instance (virtual machine), resources, and evaluation. This means that with this system it will be possible to reproduce environments in which the code needs to be executed, for that there will be a video where it will be shown how to reproduce the code, instance (virtual machine), description, additional resources, and part for an evaluation to determine if what is in the video corresponds to what is in the instance.
