Improving prediction of stock market indices by analyzing the psychological states of Twitter users.
In many languages of the world, the forms in the irrealis domain (subjunctive, conjunctive, conditional) are also used in complement clauses. The set of verbs that require subjunctive complementation is similar but not identical across languages. The paper identifies Russian verbs licensing subjunctive in complement clauses, either as the only option or as an alternative to the indicative. Basing on the Russian National Corpus, a list of these predicates is compiled, with relative frequencies of subjunctive vs. indicative for each predicate. The main result of the study is distinguishing two types of subjunctive complement clauses. Most predicates belong to the group which is similar to purpose clauses with чтобы, both semantically and syntactically. The subject of the main predicate is involved in the situation described by the subordinate clause by wishing it to be realized, by intention, or causal relations. The second, minor group includes epistemic uses of чтобы with e.g. сомневаться and other predicates in the context of negation, interrogation and other constructions expressing low probability.
The volume contains the abstracts of the 12th International Conference "Intelligent Data Processing: Theory and Applications". The conference is organized by the Russian Academy of Sciences, the Federal Research Center "Informatics and Control" of the Russian Academy of Sciences and the Scientific and Coordination Center "Digital Methods of Data Mining". The conference has being held biennially since 1989. It is one of the most recognizable scientific forums on data mining, machine learning, pattern recognition, image analysis, signal processing, and discrete analysis. The Organizing Committee of IDP-2018 is grateful to Forecsys Co. and CFRS Co. for providing assistance in the conference preparation and execution. The conference is funded by RFBR, grant 18-07-20075. The conference website http://mmro.ru/en/.
Data management and analysis is one of the fastest growing and most challenging areas of research and development in both academia and industry. Numerous types of applications and services have been studied and re-examined in this field resulting in this edited volume which includes chapters on effective approaches for dealing with the inherent complexity within data management and analysis. This edited volume contains practical case studies, and will appeal to students, researchers and professionals working in data management and analysis in the business, education, healthcare, and bioinformatics areas.
In an effort to make reading more accessible, an automated readability formula can help students to retrieve appropriate material for their language level. This study attempts to discover and analyze a set of possible features that can be used for single-sentence readability prediction in Russian. We test the influence of syntactic features on predictability of structural complexity. The readability of sentences from SynTagRus corpus was marked up manually and used for evaluation.
This paper is an overview of the current issues and tendencies in Computational linguistics. The overview is based on the materials of the conference on computational linguistics COLING’2012. The modern approaches to the traditional NLP domains such as pos-tagging, syntactic parsing, machine translation are discussed. The highlights of automated information extraction, such as fact extraction, opinion mining are also in focus. The main tendency of modern technologies in Computational linguistics is to accumulate the higher level of linguistic analysis (discourse analysis, cognitive modeling) in the models and to combine machine learning technologies with the algorithmic methods on the basis of deep expert linguistic knowledge.
The form whose main function is to express indirect commands, called the third person Imperative, Jussive or Exhortative, when compared to the prototypical (second person) Imperative, shows semantic and formal similarities and distinctions at the same time. The study describes formal and functional patterns of Jussive and places this category within the typology of the related categories, such as Imperative and Optative, based on data from six East Caucasian languages (Archi, Agul, Akhvakh, Chechen, Icari and Kumyk). Five formal patterns of Jussive are attested in these languages, including a specialized form, constructions derived from want, from tell him to do and from make him do and the Optative. Jussive forms may express such meanings as third person command, indirect causation, permission, indifference towards the accomplishment of an action and an assumption. While the Jussive is crucially different from the second person Imperative in that it introduces a third participant, this article shows that it is the addressee, not a third person, who is the central participant of a Jussive situation from both formal and functional points of view.
The paper examines the structure, governance, and balance sheets of state-controlled banks in Russia, which accounted for over 55 percent of the total assets in the country's banking system in early 2012. The author offers a credible estimate of the size of the country's state banking sector by including banks that are indirectly owned by public organizations. Contrary to some predictions based on the theoretical literature on economic transition, he explains the relatively high profitability and efficiency of Russian state-controlled banks by pointing to their competitive position in such functions as acquisition and disposal of assets on behalf of the government. Also suggested in the paper is a different way of looking at market concentration in Russia (by consolidating the market shares of core state-controlled banks), which produces a picture of a more concentrated market than officially reported. Lastly, one of the author's interesting conclusions is that China provides a better benchmark than the formerly centrally planned economies of Central and Eastern Europe by which to assess the viability of state ownership of banks in Russia and to evaluate the country's banking sector.
The paper examines the principles for the supervision of financial conglomerates proposed by BCBS in the consultative document published in December 2011. Moreover, the article proposes a number of suggestions worked out by the authors within the HSE research team.
