|Professor of Computational Linguistics
|Research Director CLiPS Computational Linguistics Group
Computational linguists build computer systems that can learn and use language. The long term goal is to understand how people acquire and process language and to make computers and robots able to do the same.
Research on Conversational Agents (Chatbots)
Research on Clinical NLP
Research on NLP for Hate Speech Detection
Overview of current and (selected) past projects
I'm directing the University of Antwerp's core facility on text mining TEXTUA. We provide help on applying text analysis tools and methods to scientists from all research areas that use text data.

Short CV: Walter Daelemans is professor of Computational Linguistics at the University of Antwerp where he directs the CLiPS computational linguistics research group. His research interests are in applying machine learning techniques to natural language processing; computational psycholinguistics (modeling how people acquire and use language); computational stylometry, with a focus on authorship attribution and author profiling from text; and language technology applications, for example biomedical information extraction, cybersecurity systems for social networks, and conversational agents using large language models.
Some background: I studied linguistics (“Germanic Philology”) and psycholinguistics in Belgium at the Universities of Antwerp and Leuven. I moved to The Netherlands in 1984 to work as a research assistant at the Radboud University in Nijmegen in Gerard Kempen’s group, which was pioneering language technology in The Netherlands at the time. After military service at the Royal Military School in Brussels, I worked at the Artificial Intelligence Laboratory of Luc Steels, where I was responsible for an ESPRIT project on office automation. In 1987 I finished my Ph.D. (University of Leuven) on an object-oriented computer model of Dutch morphology and phonology and its applications in language technology, supervised by Flip Droste and Gerard Kempen. Although I was trained in the eighties “handcrafting” Artificial Intelligence tradition (using LISP programming), I already started working at the AI-Lab on machine learning approaches to language (inspired mainly by work on genetic algorithms by Goldberg and on memory-based reasoning by Stanfill and Waltz). This led to work on Memory-Based Language Processing (Cambridge University Press, 2005), an exemplar-based approach to NLP and Computational Psycholinguistics with Antal van den Bosch, Steven Gillis, and others. From 1989, I took up a lectureship in the Computational Linguistics group of the faculty for Language and Literature at Tilburg University where I founded the ILK (Induction of Linguistic Knowledge) research group a few years later, on the basis of a large grant from NWO. I ended my affiliation in Tilburg as a part-time professor of “Machine Learning and Language Technology” in 2006. Since 1999, I am a full-time professor at the University of Antwerp (UAntwerp), teaching Computational Linguistics and Artificial Intelligence courses and directing the Computational Linguistics group of the CLiPS (previously CNTS) research center.
