In relational databases you can store information and data without losing the relationships between those data. They are therefore useful tools for computer scientists. There is, however, a gap between the relational database research community and data scientists. This leads to inefficient use of databases…

Leiden researchers have compiled information collected by scientists over the past 120 years into a database of plant-fungal interactions. This important biological data is now freely available for researchers and nature conservationists. Publication in New Phytologist.

An organized overview of the current global fungal diversity, that is what Irene Martorelli and colleagues try to achieve with the new MycoDiversity Database (MDDB) she builds in collaboration with Naturalis Biodiversity Center. The new database will make it easier and quicker to observe which fungi…

Pharmaceutical research should make more use of data science, says Gerard van Westen, postdoctoral fellow at the Leiden Academic Centre for Drug Research (LACDR). ‘If we want to have better drugs, we should start with data.’

In this project of the Center for Public Values & Ethics (CPVE) ongoing research is conducted on the history of advice to Dutch central government by so-called State committees from 1814 to 2014. State committees have been installed by Dutch central government since 1814 to provide expert advice, research…

Corruption, integrity (or a lack thereof…) and public values are near omnipresent elements in public administration and politics of all times. Cases of corrupt public officials and politicians continuously emerge. Strangely enough, however, it often remains unknown what actually occurred, how something…

This project aims at studying the social media reception of African publications as covered by the most important “altmetric” sources.

Knowledge and culture subproject 2:

Due to the modern techniques of combinatorial chemistry and high-throughput screening, data on the biological activity of many millions of compounds is known. However, it is still very difficult to transfer this data into knowledge: if we know that compounds A and B bind to a certain protein with high…

During international training-sessions for judges on the JudgeCo project by the end of 2014, the LLS-team received several questions on the meaning of a protocol within the framework of international insolvencies. It appeared to be an obscure phenomenon. The LLS team promised to conduct a study on the…

Bert Fraussen, Assistant Professor at Leiden University, Adrià Albareda, a PhD candidate at Leiden University and Caelesta Braun, Associate Professor at Leiden University, identified combinations of consultation tools and analyzed their implications for stakeholder diversity.

Interactive exploration of large volumes of data is increasingly common, as data scientists attempt to extract interesting information from large opaque data sets. This scenario presents a difficult challenge for traditional database systems, as (1) nothing is known about the query workload in advance,…
