The Internet faces such problems as the issue of privacy and security of the information transmitted, the issue of insufficient access to the web in some parts of the world, and some technical issues in such a seemingly high-tech system. As long as there is an Internet business, this topic will always be relevant. The need to combine optimal information systems with models of interaction between users is a constant problem that researchers, business, and government agencies are trying to find a solution. Each of the participants in this process considers the situation from their own point of view. However, the achievements of all parties form one or another model that determines the development of information systems and technologies. The models of the information business are analyzed, the directions of information commerce and the factors for the effective implementation of business models and the attractiveness of the Internet market are considered in the article. The choice of topic is determined by international trends aimed at developing business with minimal barriers for consumers in terms of receiving goods or services. In particular, during the period of struggle with COVID-19, when people are forced to stay at home, those companies that are poorly represented on the Internet will not be able to achieve success in their work. However, without the development of an optimal information infrastructure, software and sites, technologies and models, it is impossible to ensure fast customer acquisition and service.</p> Mikhail Gasparian Irina Kiseleva Elena Chernysheva Irina Androshina Copyright (c) 2020 COMPUSOFT: An International Journal of Advanced Computer Technology 2020-06-30 2020-06-30 9 6 3705 3713 NOVEL HYBRID THREE SIGMA (3∑W.I.S.D.O.M) APPROACH: DEEP MULTIMODAL FUSION FOR SMART CITY APPLICATIONS TOWARD WISDOM <p>In big data era, data shows characters of large volume and velocity, especially variety that is also called heterogeneity, which is the generated datasets from various city domains. Recently, modeling heterogeneous data sources has gathered significant interest especially with the power of artificial intelligence. AI and big data, as it is the case with every tool, are used for good and bad whereas in reality we do not need just intelligence. We need wisdom to create a new powerful and complete image. Our concept is based on the inspiration from human being that every system is like a human being with five senses and the intuition or the sixth sense will be the result of the fusion of all other senses to pave the way to wisdom. In this paper we will showcase how diversity and heterogeneity are key to Fusion for better behaviour and&nbsp; Decision which is the area of the study of many domains like Healthcare, Self-driving cars, and smart Recruitment. Then, we will propose our novel hybrid three Sigma (3∑ w.i.s.d.o.m ) approach, Deep Multimodal Fusion for smart city applications toward wisdom.</p> Fadwa FATHI M. OUZZIF N.

As a result of data preprocessing, three objects were formed: 1) Ischemic heart disease. Unstable angina pectoris; 2) Ischemic heart disease. Acute myocardial infarction; 3) Ischemic heart disease. Arrhythmic form. Further, the issues such as classifying, selecting a set of informative features that differentiate between class objects were solved using Fisher criterion, and algorithms for an estimate calculation as well as software programs for them were developed. As a result of data preprocessing, reference classes were formed. Objects that had fallen outside of their class during the formation process were excluded from the training set. A classification and a set of informative features were selected using established classes. Initially, three class objects, each containing 62 features, were provided by medical professionals, and as a result of data preprocessing, three sets consisting of 131, 115, and 40 objects, respectively, in the three classes were used to form a reference table.</p> Akhram Khasanovich Nishanov Gulomjon Primovich Djurayev Malika Akhramovna Khasanova Copyright (c) 2020 COMPUSOFT: An International Journal of Advanced Computer Technology 2020-07-02 2020-07-02 9 6 3725 3732 Prospects and Issues of Legal Regulation and Application of Blockchain Technology in the Civil Law Transactions of the Russian Federation <p>The article is dedicated to the assessment of blockchain technology from the point of view of the prospects of legal regulation and the possibility of using it in business and other activities, considering the legal field of the Russian Federation. The methodological basis of the study is a set of methods of scientific knowledge, among which the main place is occupied by the methods of historicism, systematicity, and analysis. The paper considers such technical features of blockchain systems that have a direct impact on both current and future legal regulation of relations emerging in connection with the use of blockchain systems.</p><p>Results: the blockchain technology is examined from the point of view of performing the functions of the payment system and other methods of application, such as using distributed information storage, decentralized decision-making, as a replacement for traditional contracts. The article presents a study of the views on the legal nature of a smart contract, considering changes in civil law. The author examines in detail the nature of a smart contract as an agreement at the three stages of its dynamics: conclusion, execution, and violation. The article discusses the features of blockchain technology that predetermine the features of smart contracts and the specifics of their application.</p><p>Conclusions: the definition of the place of a smart contract in the system of civil law agreements is proposed. A smart contract, taking into account its features, is a contractual design, and not a contract form, which has the following characteristics: conclusion and existence in exclusively electronic form in the blockchain system; automatic execution of an emerging counter contractual obligation without the need for a separate expression of the will of the parties to the contract; the impossibility of changing the smart contract after it was posted on the blockchain network, even by agreement of the parties. The classification of named civil contracts in terms of the possibility of their existence in the form of a smart contract design was carried out.</p> Aleksei Churilov Copyright (c) 2020 COMPUSOFT: An International Journal of Advanced Computer Technology 9 6 3733 3742
