NATURAL LANGUAGE PROCESSING
My work concerns the design of models and algorithms that learn to represent, understand, and generate language data. Examples of specific problems I am interested in include language modelling, machine translation, syntactic parsing, textual entailment, text classification, and question answering. I also develop techniques to approach general machine learning problems such as probabilistic inference, gradient and density estimation.

I work on responsible machine learning and representation learning for natural language processing. I am interested in tasks and applications where commonsense and real-world knowledge are necessary, including vision & language and applications in medicine and psychology.

Our research is focused on developing intelligent technology to connect people to information. Topics include search engines, recommender systems, and conversational assistants. We follow a data-driven, machine learning-based approach to contribute to fundamental knowledge in the area of information retrieval with new algorithms, new models, and new evaluation methodology.

My research is focused on computational linguistics, cognitive modelling and artificial intelligence in order to understand how we use language to communicate with each other in situated environments and how dialogue interaction shapes learning — about the world and about language itself. Topics include: computational pragmatics, visually grounded language and visual reasoning, conversational agents and learning from interaction, language variation and change in communities of speakers.

My group investigates intelligent systems that support people in their work with data and information from diverse sources. This includes addressing problems related to the preparation, management, integration and reuse of both structured and unstructured data. Topics include: data management for machine learning, information integration, causality-inspired machine learning, automated knowledge graph construction, data provenance.
Topic areas: knowledge graphs, data management for ML, data reuse, data provenance
My research is focused on building the necessary methods and technology to enable human – machine collaboration for retrieving information by obtaining a deeper understanding of user preferences and decisions during information seeking activities, developing algorithms that can interact with users during information seeking activities, and building the appropriate evaluation methodology to measure progress.

My research focuses on automated information access, in particular access across languages. Topics of interest to me are: Statistical Machine Translation, Cross-Language Information Retrieval, Data Mining for Natural Language Processing.
Topic areas: machine translation, natural language processing
My research is in the area of natural language processing, with a specific focus on machine learning for natural language understanding tasks. My current interests include few-shot learning and meta-learning, cognitively-inspired models of language, joint modelling of language and vision, and multilingual NLP. My work also explores practical applications of NLP that can have direct societal impact, for instance, in the areas of hate speech and misinformation detection. At the UvA, I lead the Amsterdam Natural Language Understanding Lab, actively collaborating with industrial partners, such as Google, Facebook and Deloitte.

Our research concentrates on statistical learning for language understanding and for modeling human language processing phenomena. Earlier work focused on developing statistical learning algorithms for NLP and on devising structured statistical models for machine translation, paraphrasing, semantic and morpho-syntactic parsing. We collaborate with industrial partners for the exchange of knowledge and research outcomes leading to the development and deployment of actual systems in practical settings.

My research is primarily on natural language understanding (e.g., question answering, information extraction, and semantic parsing) and language generation (e.g., summarization and machine translation). In my group, we are specifically interested in developing methods for reducing the need for expensive human annotation (semi-supervised, self-learning, integrating inductive biases), making the models robust under changes in data distribution (including systematic, compositional generalization) and building models interpretable to human users.
Topic areas: natural language processing, generation, interpretability, systematic generalization
My group does research in natural language processing, with a focus on interpretability techniques and the cognitive, neural relevance of modern language models, and venturing into the domains of music processing and language evolution. Our contributions include work on iterated learning, techniques for analyzing grammar learning in children and non-human animals, constituency and dependency parsing, tree-shaped LSTMs and other neural networks, interpretability techniques like diagnostic probes and Shapley-based attributions, and correlating brain activity to word and sentence embeddings. We published both at AI venues (NeurIPS, ACL, EMNLP, JAIR) and in cognitive science journals and conferences (PNAS, TopiCS, CogSci).
