will consist of biofuels rather than conventional petrol or diesel by 2020. But this component of the Commission's goals is just one that has been causing concern for researchers. In the face of rapidly rising demand for crops to be used as food, and growing worries about the true environmental benefit of some potential biofuels, concerns have been raised about this EU target.

Wrangling Galaxy’s reference data

UNLABELLED The Galaxy platform has developed into a fully featured collaborative workbench, with goals of inherently capturing provenance to enable reproducible data analysis, and of making it straightforward to run one's own server. However, many Galaxy platform tools rely on the presence of reference data, such as alignment indexes, to function efficiently. Until now, the building of this cac...

Towards Automated Relational Data Wrangling

It is well-known in data science that 80% of the work is devoted to preprocessing and only 20% to the actual machine learning or data mining step. This motivates us to explore different ways to (help) automate that preprocessing step. This note focusses on the question whether it is possible to (help) automate the data wrangling process for tabular data in data science.

Data Wrangling for Big Data: Towards a Lingua Franca for Data Wrangling

Wrangling categorical data in R

Data wrangling is a critical foundation of data science, and wrangling of categorical data is an important component of this process. However, categorical data can introduce unique issues in data wrangling, particularly in real-world settings with collaborators and periodically-updated dynamic data. This paper discusses common problems arising from categorical variable transformations in R, dem...
