Welcome to my home page!
Anssi Yli.Jyrä, Ph.D., docent at the University of Helsinki,
University Researcher, the University of Helsinki

I am a Finnish computational linguist involved in international collaboration at various levels. My research interests include:

algorithmics: basic research on weighted finite-state algorithms in NLP context
supervised machine learning: kernel methods, cover languages, weighted transducers, semirings, weighted logic, statistical machine translation
rewriting in NLP: finite-state based tokenization and segmentation, morphology, phonology, and syntax, similarity, edit distance, error correction, text normalization
substring logics: autosegmental, non-concatenative and multi-linear systems, contextual and generalized restrictions, proportional analogies, FO logics for rational relations, closure properties
surface syntax: Marcus contextual grammars, non-projective bracketed MCS dependency grammars
parameterization: trajectories, bandwidth, tracking, descriptive complexity, regular approximations
multilingual society: applications of FSM technology to the world's 7000 languages, Semitic and Bantu languages

My prior work includes:

semantics of contextual rules and transducer compilation from them
complexity measures for non-projective dependency grammars
fine-grained morpheme-aligned bilingual texts

My hobbies include violin playing, book reading and model construction.
