Interdisciplinary approach to language

The article deals with the phenomenon of interdisciplinarity regarded as one of the main methodological principles of modern linguistics. Under discussion are the problems of the anthropocentric paradigm which at present takes a dominant place among other scientific paradigms. The relationships between interdisciplinarity and other methodological principles such as anthropocentrism, functionalism and explanatorism have been analyzed. The levels of interdisciplinarity as polydisciplinarity and transdisciplinarity have been highlighted. The assumption that some notions, such as discourse, concept, linguocultureme, foregrounding are interdisciplinary by nature, and can not be discussed within the framework of one discipline, is put forward. From the position of interdisciplinarity the scientific status of such disciplines as stylistics and cognitive linguistics has been discussed. One of the conclusions is that the interdisciplinary synthesis of Stylistics is determined by its internal links with all the language aspects (phonological stylistics, stylistic grammar, lexical stylistics, stylistic phraseology, stylistics of word-formation), and external correlations of Stylistics with the disciplines of the anthropocentric paradigm. As for the interdisciplinary status of Cognitive Linguistics, it is characterized by two tendencies: 1) correlations with both humanitarian sciences (Philosophy of language, Sociolinguistics, Linguoculturology), natural sciences (Psycholinguistics, Neurolinguistics), exact and technical sciences (Mathematical Linguistics, Computer Linguistics); 2) interpenetration of many notions and methods of analysis of Cognitive Linguistics and other sciences. The main conclusions of the research are the assumptions about: a) interdisciplinarity as a basic methodological principle of modern linguistics; b) a variety of forms, types and levels of interdisciplinarity; c) the interdisciplinary status of all the anthropocentric trends of modern linguistics; d) the peculiar features of interdisciplinarity in Stylistics and Cognitive Linguistics; e) the necessity of an interdisciplinary approach to the analysis of many notions of modern linguistics.

Variation in mild context-sensitivity

Aravind Joshi famously hypothesized that natural language syntax was characterized (in part) by mildly context-sensitive generative power. Subsequent work in mathematical linguistics over the past three decades has revealed surprising convergences among a wide variety of grammatical formalisms, all of which can be said to be mildly context-sensitive. But this convergence is not absolute. Not all mildly context-sensitive formalisms can generate exactly the same stringsets (i.e. they are not all weakly equivalent), and even when two formalisms can both generate a certain stringset, there might be differences in the structural descriptions they use to do so. It has generally been difficult to find cases where such differences in structural descriptions can be pinpointed in a way that allows linguistic considerations to be brought to bear on choices between formalisms, but in this paper we present one such case. The empirical pattern of interest involves wh-movement dependencies in languages that do not enforce the wh-island constraint. This pattern draws attention to two related dimensions of variation among formalisms: whether structures grow monotonically from one end to another, and whether structure-building operations are conditioned by only a finite amount of derivational state. From this perspective, we show that one class of formalisms generates the crucial empirical pattern using structures that align with mainstream syntactic analysis, and another class can only generate that same string pattern in a linguistically unnatural way. This is particularly interesting given that (i) the structurally-inadequate formalisms are strictly more powerful than the structurally-adequate ones from the perspective of weak generative capacity, and (ii) the formalism based on derivational operations that appear on the surface to align most closely with the mechanisms adopted in contemporary work in syntactic theory (merge and move) are the formalisms that fail to align with the analyses proposed in that work when the phenomenon is considered in full generality.

Formation of a generalized semantic network of concepts

The subject of research is the features of formation of a generalized semantic network of concepts. The purpose of article is to substantiate the composition and main types of nodes and relationships characteristic of the semantic network of concepts, as well as the formation of a generalized semantic network of concepts for structural and linguistic recognition of images in computer systems and networks. Research methods: methods of the theory of mathematical logic, mathematical linguistics and set theory; methods of information visualization using graphs. Results: an approach to the formation of a generalized semantic network of structural and linguistic concepts of contour images of objects obtained at different shooting angles is proposed; the substantiation of the composition and types of nodes and relations, characteristic of the semantic network of concepts, has been carried out; the basic principles of constructing a semantic network of structural and linguistic concepts of recognition objects are formulated. Conclusions: To construct an image description that corresponds to the concept of semantic information processing and can be used in systems for collecting relevant images in computer systems and networks, it is advisable to use a structural-linguistic approach to recognition using a generalized semantic network of concepts. The use of this network in the classification and identification of objects can significantly expand the range of images accepted for consideration, taking into account different directions of shooting and different angles of camera deviation from nadir position.

Development of a Linguistic Approach to the Problem of the Computer Electrocardiogram’s Classifications

Introduction. The linguistic approach, based on the transition from the observed cyclic signal to a sequence of symbols (codeword), which characterize the dynamics of indicators from cycle to cycle, makes it possible to use the procedures of mathematical linguistics to increase the reliability of decisions. The purpose of the article is to expand the diagnostic capabilities of the linguistic approach to the analysis and interpretation of electrocardiograms (ECG). Methods. Each ECG cycle is encoded with one of four symbols characterizing changes in two indicators: traditional (cycle duration) and original (symmetry of the repolarization area). Results. Based on the processing of real clinical data of verified patients and healthy volunteers, standards of patients with chronic coronary artery disease (СAD) and healthy patients. The standards are developed using computational procedures of mathematical linguistics – the Levenshtein distance, which is the minimum number of editing operations (insertion, deletion and replacement of a character), ensuring the transition from one word to another and the frequency of occurrence of substrings in the analyzed word. On the basis of these procedures, decision rules that have been developed allow making diagnostic decisions based on the Levenshtein distance to the standards and the frequency of occurrence of one-, two- and three-symbol patterns in code words. It was found that the combination of these two methods expands the diagnostic capabilities of the linguistic approach to the analysis and interpretation of the ECG. Conclusions. It has been shown that using of the developed decision rules makes it possible to increase the sensitivity and specificity of diagnostics even in cases when the ECG does not show traditional electrocardiological signs of myocardial ischemia.

From mathematical linguistics to philology: Some remembered impressions

The author recalls her youth in Wroclaw where Jerzy Woronczak — a philologist and one of the pioneers in applying mathematical linguistics to literary analysis — worked. Woronczak was a true master for his students in the nineteen-seventies and eighties. It is interesting to trace the paradoxical journey from traditional Polish philology to mathematical linguistics, semiotics and structuralism fifty years ago, and from them to the new philology as a phenomenon of digital humanities.

Solomon Marcus Contributions to Theoretical Computer Science and Applications

Solomon Marcus (1925–2016) was one of the founders of the Romanian theoretical computer science. His pioneering contributions to automata and formal language theories, mathematical linguistics and natural computing have been widely recognised internationally. In this paper we briefly present his publications in theoretical computer science and related areas, which consist in almost ninety papers. Finally we present a selection of ten Marcus books in these areas.

The Entropy Universe

About 160 years ago, the concept of entropy was introduced in thermodynamics by Rudolf Clausius. Since then, it has been continually extended, interpreted, and applied by researchers in many scientific fields, such as general physics, information theory, chaos theory, data mining, and mathematical linguistics. This paper presents The Entropy Universe, which aims to review the many variants of entropies applied to time-series. The purpose is to answer research questions such as: How did each entropy emerge? What is the mathematical definition of each variant of entropy? How are entropies related to each other? What are the most applied scientific fields for each entropy? We describe in-depth the relationship between the most applied entropies in time-series for different scientific fields, establishing bases for researchers to properly choose the variant of entropy most suitable for their data. The number of citations over the past sixteen years of each paper proposing a new entropy was also accessed. The Shannon/differential, the Tsallis, the sample, the permutation, and the approximate entropies were the most cited ones. Based on the ten research areas with the most significant number of records obtained in the Web of Science and Scopus, the areas in which the entropies are more applied are computer science, physics, mathematics, and engineering. The universe of entropies is growing each day, either due to the introducing new variants either due to novel applications. Knowing each entropy’s strengths and of limitations is essential to ensure the proper improvement of this research field.

The role of problem-solving methods in teaching

This article reveals the pedagogical concept of “teaching methodˮ – one of the key concepts of didactics, a kind of synthesis of the most important components of the educational process: goals, content, principles, forms of teaching, and educational functions. The role of teaching methods used for new experimental course Mathematical Linguistics, is still a truly unexplored sector of Pedagogy. Based on modern requirements for teaching methods, we can distinguish three types of teaching and, accordingly, its three structures that historically evolved in the process of social development. There are three types of educational process in a modern school, and each of them should be considered as a subsystem of a single classroom system: informational-reporting, explanatory-illustrative and problem-solving. Since the founding of the school, scientists have noticed that a large number of teachers and students’ activities are used during a lesson. They were called teaching methods. The first attempts to identify teaching methods were related to the forms of their recognition, which developed a basis for teaching method classification. Problem-solving method of teaching means the interconnected activity of a teacher and students, which is built on the logic of problem setting with the following search for its solution and aimed at the “discoveryˮ of new knowledge, skills, and abilities by students themselves. One of the main functions of problem-solving method is the formation of students’ independent thinking, development of their creativity. In order to prepare students to creative activity, it is necessary to involve them in independent problem solving process, searching for solutions and making creative decisions. Keywords: teaching method, problem-solving method, problem situation, role play, collective research, dispute, hypothesis.

THE IMPORTANCE OF LINGUISTIC MODELS IN THE DEVELOPMENT OF LANGUAGE BASES GE BASE

Relevance. In Uzbek linguistics, a number of studies have been carried out on automatic translation, the development of the linguistic foundations of the author's corpus, the processing of lexicographic texts and linguistic-statistical analysis. However, the processing of the Uzbek language as the language of the Internet: spelling, automatic processing and translation programs, search programs for various characters, text generation, the linguistic basis of the text corpus and national corpus, the technology of its software is not studied in any monograph. The article discusses such problems as: the transformation of language into the language of the Internet, computer technology, mathematical linguistics, its continuation and the formation and development of computer linguistics, in particular the question of modeling natural languages for artificial intelligence. The Uzbek National Corps plays an important role in enhancing the international status of the Uzbek language.
