SentiRuEval competition
Sentiment analysis competition organizer
I co-organized the Russian sentiment analysis evaluation SentiRuEval-2015 and SentiRuEval-2016, which was focused on the reputation monitoring of banks and telecom companies on Twitter. All competition materials can be found on GitHub at this link: https://github.com/mokoron/sentirueval.
I was responsible for the following:
  • development of a crowdsourcing platform for labeling data;
  • collection and preparation of train and test data;
  • evaluation of participant systems and results;
  • preparing for publication.

The results of labeling were the follows:

  • The labeling was attended by 112 people from 7 countries and 25 cities.
  • In total, 45439 ratings were put down.
  • At least four participants labeled each text. (805 texts - 4 assessors, 7704 - 5 assessors)

Education
Bachelor of Science degree in applied mathematics and computer science
In 2003, I enrolled in the Department of Mechanics and Mathematics at the Novosibirsk State University (NSU), located in "science-city" of Akademgorodok in Novosibirsk. NSU is one of the top universities in Russia, offering a combination of basic education and practical experience in the Institutes of the Siberian Branch of the Russian Academy of Sciences. Received a bachelor's degree after successfully defending the thesis "Designing methods and tools for setting queries for research systems using ontology and a subject dictionary."

Master of Science in Mathematics and Computer Science
Execution and presentation of graduate qualification work: “Aspect-based sentiment classification of reviews from twitter for the task of reputational analysis.
With final grade of “Magna cum laude” (excellent).
Ph.D. in engineering, Data Science
In 2020 I defended my Ph.D. thesis. The dissertation title: Overcoming degradation in sentiment classification for the collections separated in time.
