We present RuDSI, a new benchmark for word sense induction (WSI) in Russian.
Contextualized language models for semantic change detection: lessons learned
Our findings show that contextualized methods can often predict high change scores for words which are not undergoing any real diachronic semantic shift in the lexicographic sense of the term (or at least the status of these shifts is questionable).
Do Not Fire the Linguist: Grammatical Profiles Help Language Models Detect Semantic Change
In this work, we explore whether large pre-trained contextualised language models, a common tool for lexical semantic change detection, are sensitive to such morphosyntactic changes.

Large-Scale Contextualised Language Modelling for Norwegian
We present the ongoing NorLM initiative to support the creation and use of very large contextualised language models for Norwegian (and in principle other Nordic languages), including a ready-to-use software environment, as well as an experience report for data preparation and training.
Representing ELMo embeddings as two-dimensional text online
We describe a new addition to the WebVectors toolkit which is used to serve word embedding models over the Web.
RuSemShift: a dataset of historical lexical semantic change in Russian
We present RuSemShift, a large-scale manually annotated test set for the task of semantic change modeling in Russian for two long-term time period pairs: from the pre-Soviet through the Soviet times and from the Soviet through the post-Soviet times.
ELMo and BERT in semantic change detection for Russian
We study the effectiveness of contextualized embeddings for the task of diachronic semantic change detection for Russian language data.

We apply contextualised word embeddings to lexical semantic change detection in the SemEval-2020 Shared Task 1.
Word Sense Disambiguation for 158 Languages using Word Embeddings Only
We use this method to induce a collection of sense inventories for 158 languages on the basis of the original pre-trained fastText word embeddings by Grave et al. (2018), enabling WSD in these languages.
\'UFAL-Oslo at MRP 2019: Garage Sale Semantic Parsing
This paper describes the {\'U}FAL--Oslo system submission to the shared task on Cross-Framework Meaning Representation Parsing (MRP, Oepen et al. 2019).
