Item Linguistic Characteristics of Combat Post-Traumatic Stress Disorder in a Trauma Related Narrative: Computational Context-Aware Approach(2021-05-04) Didushok, Valeriia; Khairova, Nina; National Technical University “Kharkiv Polytechnic Institute”These days, an increased prevalence of post-traumatic stress disorder (PTSD) and severe depression has been reported in populations exposed to war. This paper introduces using linguistic analysis of trauma narratives in the context of the study of post-traumatic stress disorder of combatants. As a subject of the analysis, posts of people who participated in combat, obtained from topic-related discussion boards were used. The approach utilizes vocabulary adaptation in NLP using the pre-trained language BERT model in addition to descriptive statistics obtained from text. The novelty of the research lies in the use of a context-sensitive model, while most of the existing research in this area is based on statistical models that use statistical inference to discover hidden patterns.Item Media Discourse Analysis Based on Ukrainian Spoken and Written Corpus(2021-05-04) Razno, Maria; Khairova, Nina; National Technical University "Kharkiv Polytechnic Institute"This article describes Ukrainian media discourse corpus creation and the relevance of the discourse analysis task applied on this corpus, using NLP methods, that can be implemented on Python programming language. It also includes the concept of different NLP methods and algorithms, its main varieties and the most popular Python packages and libraries for working with text data. Extraction of media discourse markers analysis algorithms based on the text processing is introduced in this study. It shows how to use NLP methods in practice.Item Semantic similarity identification for short text fragments(Lviv Politechnic Publishing House, 2019-04-18) Chuiko, Viktoriia; Khairova, Nina; National Technical University «Kharkiv Polytechnic Institute»The paper contains review of the existing methods for semantic similarity identification, such as methods based on the distance between concepts and methods based on lexical intersection. We proposed a method for measuring the semantic similarity of short text fragment, i.e. two sentences. Also, we created corpus of mass-media text. It contains articles of Kharkiv news, that were sorted by their source and date. Then we annotated texts. We defined semantic similarity of sentences manually. In this way, we created learning corpus for our future system.Item Use of linguistic criteria for estimating of wikipedia articles quality(National Technical University «KhPI», 2017) Kolesnik, Anastasiia; Khairova, Nina; National Technical University "Kharkiv Polytechnic Institute"Item Methods of comparing interval objects in intelligent computer systems(National Technical University «KhPI», 2017) Shepelev, Gennady; Khairova, Nina; Institute for Systems Studies of Federal Research Center ―Computer Science and Control of Russian Academy of Sciences, Moscow, RussiaProblems of expert knowledge representation by means of generalized interval estimates approach and using methods of comparing interval alternatives in the framework of intelligent computer systems are considered. The problems are common in economy, engineering and in other domains. Necessity of multi criteria approach to comparing problem that is taking into account both preference criteria and risk ones is shown. It is proposed to use a multi-steps approach to decision-making concerning choice of preferable interval alternatives. It is based on consistent using of different comparing methods: new collective risk estimating techniques, ―mean-risk‖ approach (for interval-probability situations) and Savage method (for full uncertainty situations).
