DReaMS lab Postdoc position in abusive/offensive Language Detection and Multilinguality

Three top research teams in Amsterdam, led by Profs. Piek Vossen, Maarten de Rijke and Frank van Harmelen, together with the Huawei Consumer Business Group are starting the DReaMS lab (, a new 9-person strong collaboration on intelligent, multi-lingual conversational search.
For this project the two VU groups (KRR and CLTL) are looking for a Postdoc specialised in toxic, abusive, misleading language classification across many European languages. Although there is a lot of NLP research on this topic, it is yet not clear what defines such language, how to obtain the data and how to integrate such classification in a transparent and non-based search environment. The appointment will be for 2 years with the possibility to extend to 4 years.
We are looking for a postdoc with expertise in abusive/offensive language detection and multilinguality.

Excited about the 3rd Meet & Greet CLTL-masterstudents and Industry on Dec. 3, 2020

Every 1 or 2 year in December (2017 and 2019 and 2020) we are organizing a CLTL Meet & Greet where companies and students can exchange ideas and get to know each other.

This is an excellent opportunity to introduce your company or organization to Human Language Technology and Text Mining students, and for master students to present their research topic or area of expertise to you. The one-year Master Text Mining and the two-year Research Master Human Language Technology are programs by CLTL, one of the world’s leading research institutes in Human Language technology.

This year, we are meeting each other in GatherTown, an online, virtual space. The basic idea is: you are an avatar, and walk around in a space. As soon as you get close to someone else, your webcams turns on, allowing for conversation. This allows for very natural feeling social dynamics: you see someone walking past and join them, or “run into them”, or sub-groups form. Sounds (of people speaking, of a tv playing music) get more distant as you “walk away”.

Our GatherTown is a CLTL Poster Space. We have poster boards for 13 companies, and hung their poster there. Each company representative can stand at their poster, and students standing near there will hear the presenter. This allows for students to walk from poster to poster. Near the front of the room is a microphone. When you stand on it, your webcam (and, if you are sharing a screen, your screen) is broadcast to the entire room. This will be the place for room-wide presentations. We also made several tables where students and company representatives can sit and get to know eachother. Only people sitting at the table will hear one-another, a more natural form of a “break-out room”. We also have set up a table with student portfolios, so companies can get to know students as well.

We are excited to meet everybody and see everybody mingle @ the Meet&Greet2020!

Program December 3, 2020:

  • 13.45 – 14.00 walk-in
  • 14.00  Welcome by Professor Piek Vossen (head of CLTL)
  • 14.10  Internship procedures and details (Hennie van der Vliet)

  • 15.30 Poster session 2:
  • 16.15  walk around, meet people
  • 17.00  end of meeting


Are you highly motivated and enthusiastic with expertise in computational linguistics? Are you interested in news recommendation systems and how to improve them by making their suggestions more divers? Would you like to investigate language models that can establish similarity and diversity and see how they can be used best in an interdisciplinary team?  Then please consider applying for this position.

Rethinking News Algorithms

In this project, an interdisciplinary team consisting of experts from Law, Computational Linguistics, Computer Science and Communication Science will study how recommendations and presentation choices can optimize the diversity of consumed news. Will you help us fix the way news is spread in the 21st century?

Specifically, in this project you will work on applying NLP technologies that can identify similarities and differences between news articles.

See for more details on the project. When contacting us with questions (see below for contacting details), please name the project in the subject of your email.

Where current algorithms mainly aim for finding things that are similar to prior consumption, we envision algorithms that optimize between sufficient diversity to keep users well informed and sufficient similarity so that the user is triggered to read (and be satisfied with) the offer. Together with law (ethics) and communication science experts, you will dive various dimensions of diversity (ranging from a different view on a specific event or political decision to diversity in topics in general) and aim to design language models that can identify articles that strike the desired balance between diversity and connection.

Your duties

  • conduct reproducible computational linguistic experiments on language models for diversifying recommendation systems
  • write research articles and present your work, which is to culminate in a successful dissertation, at international conferences 
  • collaborate with the other junior and senior researchers on the team experience in or affinity with working in an interdisciplinary team
  • organize small events such as workshops and colloquia


  • master degree in computational linguistics or a related field (e.g. Artificial Intelligence or Computer Science with focus on NLP)
  • solid programming skills
  • experience in or affinity with working in an interdisciplinary team
  • fluent verbal communication and good writing skills in English
  • knowledge of Dutch is an advantage (but not strictly necessary) 


The research will be carried in a great interdisciplinary team containing experts from computational linguistics, philosophy, law, computer science and communication science. You will become part of a renown computational linguistics lab (, headed by Spinoza laureat Prof. dr. Piek Vossen. The lab is embedded in the gravity project Hybrid Intelligence offering plenty of opportunity to collaborate with reseachers of various universities across the Netherlands on fundamental aspects around collaborate, adaptive, responsible and explainable AI. In this context, you will receive joint supervision by dr. Antske Fokkens (VU) and dr. Suzan Verberne (Leiden University).
