Word Sense Disambiguation for 158 Languages using Word Embeddings Only
Varvara Logacheva, Denis Teslenko, Artem Shelmanov +7
Disambiguation of word senses in context is easy for humans, but is a major challenge for automatic approaches. Sophisticated supervised and knowledge-based models were developed t…
HHMM at SemEval-2019 Task 2: Unsupervised Frame Induction using Contextualized Word Embeddings
Saba Anwar, Dmitry Ustalov, Nikolay Arefyev +3
We present our system for semantic frame induction that showed the best performance in Subtask B.1 and finished as the runner-up in Subtask A of the SemEval 2019 Task 2 on unsuperv…
Unsupervised Sense-Aware Hypernymy Extraction
Dmitry Ustalov, Alexander Panchenko, Chris Biemann +1
In this paper, we show how unsupervised sense representations can be used to improve hypernymy extraction. We present a method for extracting disambiguated hypernymy relationships…
Watset: Local-Global Graph Clustering with Applications in Sense and Frame Induction
Dmitry Ustalov, Alexander Panchenko, Chris Biemann +1
We present a detailed theoretical and computational analysis of the Watset meta-algorithm for fuzzy graph clustering, which has been found to be widely applicable in a variety of d…
Unsupervised Semantic Frame Induction using Triclustering
Dmitry Ustalov, Alexander Panchenko, Andrei Kutuzov +2
We use dependency triples automatically extracted from a Web-scale corpus to perform unsupervised semantic frame induction. We cast the frame induction problem as a triclustering p…
An Unsupervised Word Sense Disambiguation System for Under-Resourced Languages
Dmitry Ustalov, Denis Teslenko, Alexander Panchenko +3
In this paper, we present Watasense, an unsupervised system for word sense disambiguation. Given a sentence, the system chooses the most relevant sense of each input word with resp…
RUSSE: The First Workshop on Russian Semantic Similarity
Alexander Panchenko, Natalia Loukachevitch, Dmitry Ustalov +3
The paper gives an overview of the Russian Semantic Similarity Evaluation (RUSSE) shared task held in conjunction with the Dialogue 2015 conference. There exist a lot of comparativ…
RUSSE'2018: A Shared Task on Word Sense Induction for the Russian Language
Alexander Panchenko, Anastasiya Lopukhina, Dmitry Ustalov +4
The paper describes the results of the first shared task on word sense induction (WSI) for the Russian language. While similar shared tasks were conducted in the past for some Roma…
Improving Hypernymy Extraction with Distributional Semantic Classes
Alexander Panchenko, Dmitry Ustalov, Stefano Faralli +2
In this paper, we show how distributionally-induced semantic classes can be helpful for extracting hypernyms. We present methods for inducing sense-aware semantic classes using dis…
Human and Machine Judgements for Russian Semantic Relatedness
Alexander Panchenko, Dmitry Ustalov, Nikolay Arefyev +4
Semantic relatedness of terms represents similarity of meaning by a numerical score. On the one hand, humans easily make judgments about semantic relatedness. On the other hand, th…
Fighting with the Sparsity of Synonymy Dictionaries
Dmitry Ustalov, Mikhail Chernoskutov, Chris Biemann +1
Graph-based synset induction methods, such as MaxMax and Watset, induce synsets by performing a global clustering of a synonymy graph. However, such methods are sensitive to the st…
Unsupervised, Knowledge-Free, and Interpretable Word Sense Disambiguation
Alexander Panchenko, Fide Marten, Eugen Ruppert +4
Interpretability of a predictive model is a powerful feature that gains the trust of users in the correctness of the predictions. In word sense disambiguation (WSD), knowledge-base…
Negative Sampling Improves Hypernymy Extraction Based on Projection Learning
Dmitry Ustalov, Nikolay Arefyev, Chris Biemann +1
We present a new approach to extraction of hypernyms based on projection learning and word embeddings. In contrast to classification-based approaches, projection-based methods requ…
Watset: Automatic Induction of Synsets from a Graph of Synonyms
Dmitry Ustalov, Alexander Panchenko, Chris Biemann
This paper presents a new graph-based approach that induces synsets using synonymy dictionaries and word embeddings. First, we build a weighted graph of synonyms extracted from com…
