Supervised temporal link prediction in large-scale real-world networks

August 2021

Networks used in paper.

We published a new paper in the Social Network Analysis and Mining journal!

For the first time, a systematic investigation of supervised temporal link prediction is conducted on a corpus of structurally diverse, real-world networks. We report on four contributions. It is open-access, so you can read the entire paper now!


Experimental Evaluation of Train and Test Split Strategies in Link Prediction

December 2020

Splits in link prediction.

At the Complex Networks 2020 conference, which was unfortunately completely online, I shared my latest work on different train/ test splitting strategies in link prediction.

European Sailing Network

July 2020

Communities of ports in Europe.

Nathalie van Veen finished her MSc thesis at the Human Environment and Transport Inspectorate. In her work, she uses tools from the network science domain to get a better understanding of movements of large ships in Europe. She presented her work very well both for an academic public as well for inspectors at the Human Environment and Transport Inspectorate.

Understanding Dynamics of Truck Co-Driving Networks

December 2019

Approach to undertand truck co-driving networks.

At the Complex Networks 2019 conference, I presented a link prediction approach to understanding dynamics in truck co-driving networks.


Detection of Suspicious Behaviour from Ship Transponder Data

July 2019

Michael Bosch performed his bachelor research project on detecting suspicious behaviour from AIS data. He constructed several machine learning models to predict from a given ship trajectory what kind of vessel is observed.

The next four years Leiden University and the Ministry of Infrastructure and Waterstate collaborate to investigate the use of data science. The funding of my PhD-scholarship is part of this project. I will mainly focus on applying network science to get a better understanding of behavior of companies under investigation.

Efficient Compliance Monitoring on Sulphur Dioxide Emissions of Ships

January - October 2017

When I planned to do my master thesis for the master Analytical Chemistry, I looked for projects in the public domain with a focus on data acquisition and processing. At that time the Human Environment and Transport Inspectorate used a so-called sniffer instrument from TNO. The main function of this sniffer is to see whether ships were sailing on non-compliant fuel in the Port of Rotterdam.

The objective of my research was to compare different techniques which are available for analysis of ship plumes. The first part of the thesis contains a literature review for instruments able to measure sulphur dioxide emissions. In the second part I perform analysis on data obtained from several European agencies. It is the first time (to my knowledge) that multiple instruments were compared on such a large dataset (more than 8000 measurements).
