Abstract:

Over a period of about twenty years, the IIS SB RAS has created information systems of historical orientation: the Electronic Archive of Academician A.P. Ershov, the Photo Archive of the Siberian Branch of the RAS, the Archive of the newspaper “Science in Siberia”, the Open Archive of the SB RAS, etc. Each of the resources has its own specifics but in general their content is based on the general social and territorial basis of scientific and public activities of the SB AS USSR/RAS and the Novosibirsk Akademgorodok. In this report we will look at some of the problems of integrating/disintegrating disparate electronic resources into a common platform using existing and emerging tools.

Abstract:

This paper describes the Information extraction system that was presented at SentiRuEval-2015: aspect-based sentiment analysis of users' reviews in Russian. The proposed system uses a conditional random field algorithm to extract aspect terms mentioned in the text. A set of morphological features was used for machine learning. The system intent to perform two subtasks, Task A – automatic extraction of explicit aspects and Task B – automatic extraction of all aspects (explicit, implicit and sentiment facts), and tested on two domains: restaurants and automobiles. Our systems performed competitively and showed the results comparable to those of the other 10 participants.

Abstract:

The article draws attention to the problem of measuring the effect that programming solutions have on the programming productivity and performance, in educational programming and the correctness-saving program improvements. The results of some experiments concerning these questions are discussed. The hypothesis that  functional models can provide a metric scale capable of separating features of programming languages and systems from features of programs and programming solutions is proposed. The results of a preliminary demonstrative experiment in studying the dependence of the program productivity upon the opted compiler and, on the other hand, upon the representation of the programming solution in the opted programming languages are described. Analysis of these results leads to a method that can reveal such dependencies. The long experience in sifting educational and contest programs revealed some unnoticed aspects of this problem.

Abstract: The report is devoted to the analysis of the method of comparison of programming languages, convenient for assessing the expressive power of languages and the complexity of the programming systems. The method is adapted to substantiate practical, objective criteria of program decomposition, which can be considered as an approach to solving the problem of factorization of very complicated definitions of programming languages and their support systems. The article presents the results of the analysis of the most well-known programming paradigms and outlines an approach to navigation in the modern expanding space of programming languages, based on the classification of paradigms on the peculiarities of problem statements and semantic characteristics of programming languages and systems with an emphasis on the criteria for the quality of programs and priorities in decision-making in their implementation.

Abstract: The purpose of the article is the choice of presenting the results of a comparison of programming languages, convenient for assessing the expressive power of languages and the complexity of the implementation of programming systems. Forms of such a presentation should be adapted to substantiate practical criteria for program decomposition, which can be viewed as an approach to solving the problem of factorization of very sophisticated definitions of programming languages.
The relevance of choosing concise and quickly perceived forms is useful for working in the rapidly developing space of new problem-oriented programming languages. Along the way, you can show the distance in the conceptual complexity between programming and the development of programming systems.

Abstract: The report is devoted to the analysis of the possibilities of using the modern IT potential in solving problems of processing large and complex data by the example of program texts and definitions of programming languages.

Abstract: The information visualization methods have been known as a tool providing the understanding of large data. The visualization of research publication collections is a special case of applying visualization methods to large data. This paper presents a survey of problems solved by means of visualization, document models and document analysis methods as well as of new approaches to visualization methods for research publication collections. Special attention is paid to the relation between the document analysis and visualization methods.

Abstract:

The article is devoted to the results of the analysis of modern trends in functional programming, considered as a metaparadigm for solving the problems of organizing parallel computations and multithreaded programs for multiprocessor complexes and distributed systems. Taking into account the multi-paradigm nature of parallel programming, the paradigm analysis of languages and functional programming systems is used. This makes it possible to reduce the complexity of the problems being solved by methods of decomposition of programs into autonomously developed components, to evaluate their similarities and differences. Consideration of such features is necessary when predicting the course of application processes, as well as when planning the study and organizing the development of programs. There is reason to believe that functional programming has the ability to improve programs performance. A variety of paradigmatic characteristics inherent in the preparation and debugging of long-lived parallel computing programs are shown.

Abstract:

International and Russian-language data sources that provide information about Russian research-related organizations are considered. It is demonstrated that Russian-language data sources contain more information about Russian research-related organizations than most international data sources, but this information remains unavailable for English-language data sources. Experiments on comparison and integration of information about Russian research organizations in international and Russian data sources are outlined. Data sources such as GRID, Russian and English chapters of Wikipedia, Wikidata and eLIBRARY.ru are considered. The work is an intermediate step towards the creation of an open and extensible knowledge graph.

Abstract:

The article is devoted to the development of solutions in the project of a simulator for teaching programming, intended for initial familiarization with the basic concepts of process interaction and calculation management. No matter how complex the world of parallelism is, the programmer training system will have to master it and create a methodology for fully familiarizing itself with its non-obvious phenomena. The simulator is based on the experience of controlling the interaction of toy robots moving on a checkered board. The article material is of interest to programmers, students and graduate students specializing in the field of system and theoretical programming.

Abstract: Exponential size growth of such graphs as social networks, Internet graphs, etc. requires new approaches to their visualization. Along with node-link diagram representations, adjacency matrices and various hybrid representations are increasingly used for large graphs visualizations. This survey discusses new approaches to the visualization of large graphs using adjacency matrices and gives examples of applications where these approaches are used. We describe various types of patterns arising when adjacency matrices corresponding to modern networks are ordered, and algorithms making it possible to reveal these patterns. In particular, the use of matrix ordering methods in conjunction with algorithms looking for such graph patterns as stars, false stars, chains, near-cliques, full cliques, bipartite cores and near-bipartite cores enable users to create understandable visualizations of graphs with millions of vertices and edges. Examples of hybrid visualizations using node-link diagrams for representing sparse parts of a graph and adjacency matrices for representing dense parts are also given. The hybrid methods are used to visualize co-authorship networks, deep neural networks, to compare networks of the human brain connectivity, etc.

Abstract:

Cross-lingual entity alignment algorithms are designed to look for identical real-world objects in multilingual knowledge graphs. This problem occurs, for example, when searching for drugs manufactured in different countries under different names, or when searching for imported equipment. At the moment, there are several open-source libraries that collect implementations of entity alignment algorithms as well as test data sets for various languages. This paper describes experiments with several popular entity alignment algorithms applied to a Russian-English dataset. In addition to translating entity names from Russian to English, experiments on combining the various generators of entity name embeddings with the various generators of relational information embeddings have been conducted. In order to obtain more detailed information about the results of the EA approaches, an assessment by entity types, the number of relationships and attributes have been made. These experiments allowed us to significantly improve the accuracy of several EA algorithms on the English-Russian dataset.
