Language Technology and Computational Linguistics
The research group ‘Language Technology and Computational Linguistics’ works in the areas of computational linguistics, natural language processing (NLP), and cognitive modelling. An overall research challenge concerns the enrichment of computational language models with linguistic and cognitive information. Language models based on text distribution alone are successful in many NLP tasks, but there are complex scenarios that need a deeper ‘understanding’ of text than current models can master.
Questions addressed are how we can inform models with semantic and pragmatic information known from linguistic theory, with cognitive signals such as eye tracking and EEG traces, and also with data from the visual modality (combining text with images, or speech with gesture).
Another challenge concerns the language technology gap that exists for smaller languages, including Danish, compared to e.g. English, and which must be met by increasing the creation of resources and models for Danish. Included here is the development of good and efficient methods for establishing high-quality datasets and lexical-semantic resources.
Finally, the group works on adapting NLP techniques to assist in different areas of Digital Humanities, an emerging field in the humanities where increasingly more data material has become or needs to be digitized and prepared for further digital processing and statistical analysis.
Following these lines of research, our studies fall into the following focus areas:
Methodologies for Developing NLP Language Resources
We develop principled methods for compiling NLP resources and language models that encompass cultural and societal diversity. We experiment with contextual embeddings in order to examine the correlations between the handcrafted and the statistically generated resources. We work with annotated datasets as well as with methods for building computational resources, including lexical-semantic lexicons.
Computational Cognitive Modelling and Multimodality
Seeks The general goal of this area is to explain the way humans process information by developing computational models capturing aspects of such processing. We focus on computational models of language processing and the extent to which these models make use of cognitive signals and data from the visual gestural modality, and combine them with linguistic knowledge.
NLP and Digital Humanities
This area includes computational NLP models for the analysis of textual data in its widest forms including poems, novels, letters, news articles, scientific articles, or lyrics. We perform a continuous upgrade of our NLP pipelines and corpus tools, in particular for Danish, and work to ensure that appropriate methods and gold standards are compiled for evaluating them.
