PhD student.  Jue works on scalability of the back end and the front end, and educational data science — to analyze and model data collected from proof-of-concept studies with real learners.  His research focuses on modeling learner proficiency and novel approaches to language modeling deep-learning neural nets.

PhD Student.  Anisia works on all aspects of user studies involving Russian.  Her research is on building deep-learning language models for detection of grammatical errors.  Revita needs such  models to identify "alternative-correct" answers — important situations in learning, where more than one answer is possible for an exercise.

PhD Student.  Duc works on Bayesian networks and deep learning modeling of the learners' proficiency and progress, which is essential for personalization in the Revita Project — learner competency must be modeled accurately to provide the most suitable exercises and feedback.

Duc's MS Thesis (2020) was on "Modeling knowledge states in language learning."

Project lead.  Roman Yangarber is Associate Professor at the Department of Digital Humanities, University of Helsinki (UH).  He holds the Chair in Linguistic Inequalities and Translation Technologies at INEQ: The Helsinki Inequality Initiative.  His research group — the Language Learning Lab — works on a variety of topics: studying how language works, and how computers can better understand language.  His earlier research themes include analysis of news media, and modeling language evolution.  More recent focus is on AI support for language learning.  This has resulted in a system currently in use by learners and teachers at several universities.  The research focuses on support for learning of smaller, endangered languages, as well as for "majority" languages.

Here are some of our main contributors: local, at the University of Helsinki (UH), and international.
Remote Studies — are current work with groups of learners at other universities, collecting feedback from them and researching their progress.

All of our colleagues and collaborators typically work on multiple problems and aspects of the Project at the same time, and contribute to many areas.  We list here some of them here:

  • Javad Nouri — MS Student.  Javad built all components of the first functioning Revita platform.  Initial focus on several endangered Finno-Ugric languages, Finnish, Russian.
  • Kim Salmi — MS Student.  Contributed to many front-end and back-end aspects of the early platform.
  • José María (Txema) Hoya Quecedo — MS Student.  The core back-bone for supporting cross-language handling of morphological analysis and for (shallow) syntactic analysis.  NLP topics: models of ambiguity and disambiguation.  Initial support for Romance languages (β).
  • Max Koppatz — MS Student.  Major improvements to the language-analysis layer and to exercise selection.  NLP work: deep-learning language modeling.  Language specific work on Finnish, initial support for Swedish and German (β).
  • Tomi Rikander — MS Student.  Front-end improvements and re-ingeneering.
  • Sardana Ivanova — PhD Student.  Support for Russian, Sakha (Yakut).
  • Gert Adamson — MS Student.  New front-end, enhanced user experience.
