We are collaborating on a project for computationally modelling people's intuitions about various associations of both real words and non-words (e.g., novel words or company names) for the Dutch language. The project will result in an easy-to-use openly available application in which (non-)words can be analyzed for various associations that they may evoke as well as give a list of semantically similar words.

We collaborate on finding the limits of predictability for fertility intentions using a mass collaboration (benchmark). We are opening up the participant's models to understand what information is captured by highly predictive models, and to disaggregate the predictions of the models to assess geographical and demographic biases.

Together with RIVM and the ministry of health, the SoDa team is co-authoring a scientific paper on the spread of COVID-19 in schools in the Netherlands.

Contributors: RIVM, Javier Garcia-Bernardo

Linking databases on company names is a challenging task. Company names are usually not unique and can have many spelling variations. We helped conduct a sensitivity analysis for different methods of linking these databases, which can be used to answer many different social science research questions about companies in the Netherlands.

Contributors: Peter Gerbrands, Jonathan de Bruin, Wim Coreynen

We created a workflow using existing software packages to generate synthetic datasets for the Statistics Netherlands microdata architecture. These synthetic datasets can then be used as example datasets when sharing analyses (but not original data!) with researchers.

Contributors: Jan Kabatek, Erik-Jan van Kesteren, Kyuri Park

We helped to design and set up a benchmark for a social data science challenge at the end of the SICSS-ODISSEI summerschool. The benchmark was based on microdata from Statistics Netherlands.

Contributors: Paulina Pankowska, Javier Garcia-Bernardo, Adrienne Mendrik

We are developing a metadata format which includes variable-level statistical information. This format can then be used to generate fake, synthetic datasets for testing purposes using a python package.

Contributors: Ricarda Braukmann, Erik-Jan van Kesteren, Raoul Schram

Contributors: Peter Lugtig, Erik-Jan van Kesteren, Annemarie Timmers, Javier Garcia-Bernardo

We performed data engineering work to transform 10TB of online marketing (clicks) data from a large online housing platform into an analyzable format. These datasets are used in research surrounding search behaviour on the housing market in the Netherlands. We made the processed data available as an open dataset.

Contributors: Joep Steegmans, Jonathan de Bruin

To get an overview of what citizen science projects are available in the Netherlands, we have created a website with an overview of such projects. The community can contribute their own projects via the gitub page!

Contributors: Peter Lugtig, Jonathan de Bruin, Leonardo Vida, Annemarie Timmers

We have created an R-package to perform geo-enrichment of datasets using openstreetmaps. Enriching geo-coded (latitude/longitude) data sets with features from the physical surroundings enables researchers to take into account spatial surroundings in statistical models.

Contributors: Peter Lugtig, Erik-Jan van Kesteren, Leonardo Vida

Geo-enrichment requires transferring large amounts of data from a geospatial database to a computer program. Public APIs served over the internet are usually too slow for this purpose. Hence, we have created a docker image so that the API for our osmenrich R package can be run locally.

Contributors: Peter Lugtig, Erik-Jan van Kesteren, Leonardo Vida

Using large data sets from Statistics Netherlands, we developed a data pre-processing and analysis pipeline for estimating expectations concerning the inequality of opportunity in The Netherlands using the ODISSEI Secure Supercomputer (OSSC). These estimates will be available on the project website.
