Language technology

The language technology group works on questions which involve the analysis and handling of human language. The challenges involve building models that can handle how human language changes over time, between users, topics, channels, and situations, yet make use of the obvious and observable regularities of human language use.

Applications of language technology are manifold, but of special interest for the group are terminology, writing aids, large scale text analytics, and health informatics. Methods used by the group involve general machine learning approaches as well as symbolic knowledge-based approaches.

The group has an extensive international network, with a several-year collaboration with King's College in London organised by Sumithra Velupillai. Industrial cooperation is frequent, through development projects or student internships hosted by the many companies in the Stockholm area with interests in language technology and through an adjoint professorship whereby Jussi Karlgren of Gavagai  spends part of his time at KTH. Viggo Kann is coordinating the national Swedish Language Technology Terminology Group .

There is a certain overlap of interests with TMH, but where TMH focusses on spoken language and dialogue, the language technology group works primarily on text.


The group, in collaboration with TMH, gives a class on ¬†language technology , participates in classes on search engines and information retrieval systems  and language technological tools for language consultancies, and supervises M Sc degree projects related to language technology.
