HSE Economists Use Search Queries to Forecast Birth Rates
Researchers from the HSE Faculty of Economic Sciences have shown that the accuracy of birth rate forecasts for Russia can be improved by almost 50% by incorporating the dynamics of online search queries related to pregnancy and childbirth into forecasting models. In the best-performing models, the forecasting error fell from 4.6% to 3.2%. The findings have been published in Populations and Economics.

HSE Researchers Discover Who Eats Out in Russia-And Why
Around one-third of Russians (31.3%) rarely eat out or buy ready-made meals. The core group of active consumers—those who eat out or purchase prepared food almost every day or several times a week—accounts for only about 9% of the population. These are the findings of a study conducted by the HSE Institute for Social Policy. According to the researchers eating out is no longer a marker of high social status in Russia.

Identification of Singleton Mentions in Russian

Ch. 5. P. 33–41.
Toldova S., Max Ionov

This paper describes a pilot study of the problem of detecting singleton mentions in Russian texts. A noun phrase is considered a singleton mention if it is the only referent of some entity. We discuss various morphosyntactic and lexical features, some of which were used for analogous tasks for English and propose new features derived from the discourse analysis. Testing the machine learning classifiers trained with the use of proposed features, we conclude that although the quality of classifiers is significantly lower than for English, they still have rather high precision and thus can be helpful in various tasks of mention tracking.

Employing Wikipedia data for coreference resolution in Russian

Semantic information has been deemed a valuable resource for solving the task of coreference resolution by many researchers. Unfortunately, not much has been done in the direction of using this data when working with Russian data. This work describes the first step of a research, attempting to create a coreference resolution system for Russian based on semantic data, concerned with ...

Features for Discourse-New Referent Detection in Russian
Toldova S., Ionov M., , in: Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics). 17th International Conference on Intelligent Text Processing and Computational Linguistics, CICLing 2016Vol. 1. Issue 9623.: Springer Publishing Company, 2018. P. 648–662.
This paper concerns discourse-new mention detection in Russian. This might be helpful for different NLP applications such as coreference resolution, protagonist identification, summarization and different tasks of information extraction to detect the mention of an entity newly introduced into discourse. In our work, we are dealing with the Russian where there is no grammatical devices, ...

Coreference resolution for Russian: the impact of semantic features
Toldova S., Maxim Ionov, , in: Computational Linguistics and Intellectual Technologies. International Conference "Dialogue 2017" ProceedingsVol. 1. Issue 16 (23).: M.: -, 2017. P. 339–348.
This paper presents the results of our experiments on building a general coreference resolution system for Russian. The main aim of those experiments was to set a baseline for this task for Russian using the standard set of features developed and tested for coreference resolution systems created for other languages. We propose several baseline systems, ...

Mention Detection for Improving Coreference Resolution in Russian Texts: A Machine Learning Approach
Toldova S., Ionov M., Computacion y Sistemas 2016 Vol. 20 No. 4 P. 681–696
The paper concerns discourse-new referent detection. The task of coreference resolution is essential in many text-mining applications. The focus in this task is to detect noun phrases (NPs) that refer to the same entity. In languages without articles, there are no overt grammatical clues in an NP for whether it introduces a new referent into ...

Error analysis for anaphora resolution in Russian: new challenging issues for anaphora resolution task in a morphologically rich language
Anna Roytberg, Toldova S., Alina Ladygina et al., , in: Proceedings of the Workshop on Coreference Resolution Beyond OntoNotes (CORBON 2016), co-located with NAACL 2016, San Diego, California, June 16, 2016.: Stroudsburg, PA: Association for Computational Linguistics, 2016. P. 74–83.
This paper presents a quantitative and qualitative error analysis of Russian anaphora resolvers which participated in the RU-EVAL event. Its aim is to identify and characterize a set of challenging errors common to stateof-the-art systems dealing with Russian. We examined three types of pronouns: 3rd person pronouns, reflexive and relative pronouns. The investigation has shown ...

Many NLP researchers, especially those not working in the area of discourse processing, tend to equate coreference resolution with the sort of coreference that people did in MUC, ACE, and OntoNotes, having the impression that coreference is a well-worn task owing in part to the large number of papers reporting results on the MUC/ACE/OntoNotes corpora. Given ...

Russian Coreference Corpus
Toldova S., Ladygina A., Azerkovich I. et al., , in: Input a Word, Analyze the World.: Newcastle upon Tyne: Cambridge Scholars Publishing, 2016. Ch. 7 P. 107–125.
The Russian coreference corpus was established in 2013/2014 and annotated with coreference and anaphoric relations. At present, the corpus consists of 185 texts of different genres: newswire articles and fiction texts. The texts were taken from Russian freely available online resources and manually annotated for anaphora and coreference. Our corpus was annotated taking into account language-specific ...

Abstract - RU-EVAL is a biennial event organized in order to estimate the state of the art in Russian NLP resources, methods and toolkits and to compare various methods and principles implemented for Russian. Russian could be treated as an under-resourced language due to the lack of free distributable gold standard corpora for different NLP ...

This paper is a pilot comparative study on coreference chaining in three languages, namely, Czech, English and Russian. We have analyzed 16 parallel English-Czech newspaper texts and 16 texts in Russian (similar to the English-Czech ones in length and topics). Our motivation was to find out what the linguistic structure of coreference chains in different ...
