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…

The new database will make it easier and quicker to observe which fungi…

What do you do when you’re suddenly given access to a whole lot of data but don’t know how to organise and analyse it? Maritime historians in the Faculty of Humanities joined forces with vocational college (MBO) students to build a database. ‘We’re so compatible with each other.’

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.’

Which plant species grow where - and why? In a new study in Nature Ecology & Evolution, an international research team presents the world's first global vegetation database which contains over 1.1 million complete lists of plant species for all terrestrial ecosystems. Leiden professor of Environmental…

On 23-24 October, 2023, Simona Demkova spoke at the meeting of Transnational Administrative Law Network on the transnational challenges of the EU large-scale informational cooperation, based on her recently published book, 'Automated Decision-Making and Effective Remedies'. The theme of this TALN meeting…

Scientists' computers are now full of complicated 3D models, but no standard has yet been developed for exchanging the data. A new database should change this. External PhD student Liselore Tissen is receiving a grant to contribute to this on behalf of Leiden University (and TU Delft). ‘It will be great…

It is the largest database for space ice yet: The Leiden Ice Database for Astrochemistry: LIDA. Created by astrophysicists at the Leiden Observatory, LIDA includes not only hundreds of measurement data, but also software to examine astronomical observations and prepare new measurements with the James…

Too expensive groceries, diseases suddenly breaking out: from the sixteenth to the nineteenth century, hundreds of people documented the world around them in chronicles. A significant number of these texts have been digitised in recent years. Professor of Early Modern Dutch History and project leader…

This project aims to contribute to the improvement of documentation and archiving standards (conform the FAIR principles) for systematic Mediterranean archaeological field survey.

This project aims to integrate three of the largest survey databases in the Mediterranean to study the impact of the megalopolis Rome on its direct hinterland.

The database is created by the Centre for Public Values and Ethics of the Institute of Public Administration. Its aim is to collect and describe scandals involving (supposed) corruption and lacking integrity of public officials in the Netherlands between 1945 and the present.

The European Registry of Exonerations database provides an overview of miscarriages of justice in Europe with a view to preventing future errors.

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…

What are interactive effects of human pressures on aquatic communities?

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,…

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…
