Topic: Towards Equitable and Culturally Adapted Multilingual Dialog Systems


The ability to intelligently converse with humans has been one of the fundamental objectives in the pursuit of artificial intelligence, and dialog systems are one of the prime user-facing applications of NLP technology. Task-oriented dialog systems in particular have been designed to assist or replace human operators in focused problems and domains with well-defined goals. However, designing and bootstrapping such systems that are able to cover multiple languages and/or domains without performance degradation, or even just collecting data for training and evaluation, is known to be notoriously difficult. In this talk, I will first point to the main gaps and challenges of modern task-oriented dialog systems, including the sheer lack of multilingual datasets and lack of cultural adaptation, which result in culturally biased, inequitable, English-centric, and non-adaptive systems. I will then follow up by describing new data collection protocols that enable creation of high-quality culturally adapted multi-parallel multilingual data. The new datasets unlock the potential for unprecedented quantitative and qualitative evaluation and analyses of multilingual performance disparities. I will then delve deeper into current performance and (cultural) diversity gaps and disparities in multilingual multi-domain dialog systems, and provide a quick overview of the latest algorithmic developments aiming to reduce the detected gaps.

Topic: BRUK Team’s Resources for Ukrainian Corpus Creation


The talk will focus on the key resources and tools developed by the BRUK team for the automatic processing of Ukrainian texts, especially for building Ukrainian corpora. The resources include:
* BRUK (Ukrainian Brown Corpus, a projected one-million-word POS gold standard)
* VESUM (A Large Electronic Dictionary of Ukrainian, over 420,000 lemmas and counting, for POS tagging)
* USL (Ukrainian Semantic Lexicon for semantic tagging).
The tools come in the form of the NLP_UK suite for Ukrainian text tokenization, lemmatization, POS tagging, and cleaning. The application of NLP_UK to build multiple iterations of the GRAC corpus will be discussed.
