Effectiveness of SVM Method by Naïve Bayes Weighting in Movie Review Classification

Classification of movie review belongs to the realm of text classification, especially in the field of sentiment analysis. One familiar text classification method used is support vector maching (SVM) and Naïve Bayes. Both of these methods are known to have good performance in handling text classification separately. Combining these two methods is expected to improve the performance of classifier compared to working separately. This paper reports the effort to classify movie reviews using the combined method of Naïve Bayes and SVM with Naïve Bayes as weights. This combined method is commonly called NBSVM. The results showed the best accuracy is obtained if the classification is done by the NBSVM method, which is equal to 88.8% with the combined features of unigram and bigram and using pre-processing in the form of data cleansing only.

An identification methods of under-segmented regions in segmented lung mask

The Juxtapleural nodule regions are often missed in the result of lung segmentation algorithms. To tackle this problem, an identification method basing on the SIFT information and elliptic Fourier descriptor is proposed. Firstly, the SIFT information is used to locate the position of key points in the lung mask. Then with the help of distance relationship, the support borderlines of key points are calculated. Thirdly, the elliptic Fourier descriptor is introduced to describe a support line. Finally, an adaptive threshold is designed to decide whether the current support line is corresponding to an under-segmented region. Experiments on real CT images demonstrate that the proposed model provides an efficient way to perform under-segmented region identification task.
Analisa Denyut Jantung Menggunakan Aplikasi Mobile Self Integrated BioInformatics System

Heart disease is still ranked first in the WHO most dangerous and deadly disease in the world. This is also influenced by the individual's reluctance to check his heart condition routinely. So we need an application that is able to help overcome this. SIBioS application is a mobile-based application that functions to analyze heart rate. SIBioS is useful to help with the initial diagnosis of the presence or absence of cardiovascular disorders in individuals. The method applied for data analysis in SIBioS applications is case-based reasoning. Each heart rate data obtained will be calculated the degree of closeness of the distance to the heart rate contained in the knowledge base owned. So that the individual's heart rate can be informed. The test results show SIBioS is able to provide information about the status of the heart condition tester in accordance with the real condition of the tester at the time of measurement. In addition to using the right data analysis method, the results of heart rate data analysis are also influenced by the smartwatch device which is used as a media for tapping heart rate data, gender, age, daily physical activity, individual professional status, and supporting factors when measuring the resting heart rate. Case-based reasoning analysis methods can be applied to heart rate analysis to determine the condition of a person's heart under normal conditions or the presence of cardiovascular disorders. The physical activity recommendations given by the system are determined based on the individual's heart condition.
FAIR data to accelerate scientific discovery at national scattering facilities

Rapid developments in experimental instrumentation and detectors allow researchers to collect experimental data in unprecedented amounts.At the same time advanced in computing, data analytics and machine learning open the door to accelerating scientific discovery from experimental data and offer the possibility to 'learn' from large amounts of experimental data available in the user community.However, it is still common practice that experiments, data analysis and modeling are confined to a small team of collaborating researchers and results are published in the form of scientific papers.One notable exception is crystallographic structural results being published and shared via databases such as the PDB or CSD.Using the full potential of experimental data for scientific discovery requires data to be FAIR [1]: Findable, Accessible, Interoperable and Reusable.In this contribution, these four aspects will be discussed from the point of view of Synchrotron and Neutron User Facilities.Both individual researchers in need of individual data sets to e.g.validate a theoretical model as well as the needs required for large scale data mining, data analytics and machine learning will be discussed.
Konsep Fantasi dalam Film

Fantasy films were born from the development of fiction films that have shown existence since the beginning of its history. Fantasy films have their own charm because they can penetrate time and space compared to other genres. Fiction films develop from their creators both in terms of story and cinematography because fiction films are at the center of the poles: real and abstract. Its greatest strength lies in its ability to integrate and combine with other genres without exception and can be broadly developed unlimitedly. That is because fantasy films contain elements with different characteristics from other films where if a fantasy film has one element in the making of the film then it has been said to be a fantasy film. The elements or components that are seen are derived from the narrative and cinematic elements of filmmaking which contain ideas of stories, characters, and settings in a film. These three elements are the forming components of fantasy films that are fictitious and imaginative. The idea of the story is not based on an imaginary reality, that is a fiction that makes no sense. In the case of fantasy films, filmmakers will compete to develop and present ideas that have not been thought of before, so the audience seems to be carried away in a new world outside of real life. Character characters in fantasy films are the imagination of creators in fictitious forms, such as: animal characters, extraterrestrials, monsters, robots, and non-physical characters such as ghosts, spirits and holograms. While the background elements in fantasy films have a character setting place and time imaginative events are unique in unknown times or dimensions, can be past, present, and future with the centuries formed by the creators.
THE CONCEPTION OF THE LOGIC OF NIKOLAI GROTH IN THE CONTEXT OF MODERN PHILOSOPHICAL DISCOURSES

The author of the article considers that N. Groth is building a project for a new branch of the logical theory – «genetic» («practical») logic. The subject of the latter is the self-organizing process of forming the basic, universal structures of human thinking, which constitute the initial potential for its further development.N. Groth can not be attributed to the supporters of radical («hard») naturalism, since this would contradict his model of thinking as an intersubject, free, creative process aimed at «increasing consciousness» (spirituality) of man.At the same time N. Groth considers important the unity of the unconscious and conscious levels of thinking; one of the demonstrations of this unity is the presence and combination of the same «movements» and forms: association, dissociation, integration, disintegration – at all levels of thinking, from the unconscious to the targeted «methodical».

ELECTRONIC LIBRARIES: PROBLEMS OF ACCESS TO INFORMATION

The purpose of the article is to analyze of the features of open access to world electronic databases in Ukraine.Methodology. The article uses the method of analysis and data synthesis, statistic method and other.Finding. An example of the Scientific Library of the Ivan Franko National University of Lviv there is shows the achievements in the formation of electronic libraries in Ukraine. In the article is focused on the problems of modern development of electronic libraries and to identify the vectors further their formation on the basis of national specificity.Results. Electronic libraries are an important example of radical changes in contemporary culture now. They help get access to a variety of knowledge, to preserve and get quick information about the national culture heritage, integrate electronic resources into the world socio-cultural space. The results of the this article testify to the discrepancy between the wide possibilities of access to world information and the Ukrainian practice of this access. Barriers in access to information that temporarily exist in Ukraine do not contribute to expanding the outlook of scholars, popularisation their research, raising the prestige of science and education, disseminating information about the country’s cultural values, and enhancing the status of the country in the world. Barriers in free access to scientific information had help to reveale insufficient efficiency of mechanisms financing of Ukrainian science and education.Practical value of the research is the possibility of using its results during the study of topical issues of scientific communication, bibliometrics, modern library activities, etc.
Information Security in the Arab World: Risks and Challenges

This study aims at identifying the risks and challenges facing information technology in the Arab world, through measuring the magnitude of cybercrimes; cybersecurity capabilities in the Arab world; the impact of the gap in the research and development on cybersecurity; and the legal and organizational readiness to maintain cybersecurity and its security measures in the region. This study applied the descriptive analytical method as it is the most appropriate method to achieve its objectives. The study concluded to a number of results, such as: the Arab countries vary in their exposure to cybercrime risks and their capabilities to encounter those risks; the Gulf Countries are the least capable to combat cyber-attack risks due to the lack in technical skills compared to advanced countries; and the limited spread of communication networks in some Arab countries made them less exposed to cybercrime risks. It also showed that Arab countries, except of Oman, ranked last compared to other world countries regarding the legal and regulatory readiness. Moreover, the Study highlights that there is no correlation between cybersecurity regulatory and administrative readiness for a country, and the capability to encounter cyber-attack risks. The study concluded to a number of recommendations, such as: the importance of enacting new regulations on cybercrimes; establishing a central government entity for cybersecurity-related issues; and developing a national cybersecurity strategy that clearly identifies the roles and responsibilities of entities.
Mengatasi Error Berkorelasi Menggunakan Metode Transformasi Prewhitening pada Regresi Nonparametrik Kernel Bivariat

Suppose that given 𝑛 data {(𝑋1𝑡, 𝑋2𝑡, 𝑌𝑡)}𝑛 with nonparametric regression model :𝑡=1𝑌𝑡 = 𝑚(𝑋1𝑡, 𝑋2𝑡) + 𝜀𝑡 ; 𝑡 = 1,2, ⋯ , 𝑛with 𝑚(𝑋𝑡) is a regression function and 𝜀𝑖 is a random errors. In nonparametric regression often found correlated errors, i.e. the error value does not meet the identical and independent assumptions. Correlated errors will adversely affect the estimation model. Correlated errors can be resolved by prewhitening transformation method, a method where the error is assumed to follow the model ARMA (𝑝, 𝑞). Applied on data is shown that regression model was obtained with correlated errors. The error obtained from the conventional Kernel regression model follows the AR(1) model with the value ∅1= 0.932. After the prewhitening transformation, the kernel regression model results from the prewhitening transformation with uncorrelated errors. The MSE value of the conventional Kernel estimation modal is 639203.308 smaller than the MSE value of the estimated Kernel prewhitening transformation model that is 290303.832, so the Kernel estimator resulting from prewhitening transformation is more efficient than conventional Kernel estimator.

SUBSTANTIATION OF PRAXEO-DYNAMIC APPROACH TO THE IMPROVEMENT OF FUTURE TEACHER’S READINESS FOR THE PRIMARY SCHOOLCHILD’S SPIRITUAL-MORAL DEVELOPMENT

The article is devoted to the substantiation of praxeo-dynamic approach to the improvement of future teacher’s readiness for the primary schoolchild’s spiritual-moral development. The use of this approach allows educators to develop a research program that will open new horizons in cognition and transformation of personality. The research has been conducted using scientific empirical and theoretical methods, common scientific methods: analysis, synthesis, comparison, induction and deduction. The descriptions have been used to determine the praxeo-dynamic approach to the future primary school teachers’ professional training. The article represents an analysis of studies, which suggest that a praxeo-dynamic approach to the improvement of future teacher’s readiness for the primary schoolchild’s spiritual-moral development should take into account the strength and pace of the development of each personality’s abilities. These findings confirm the idea that while working with students we should pay attention to the fact that excessive acceleration in the formation of cognitive, emotional and behavioral spheres of personality can lead to negative results (e.g, ignorance in other areas of life and interests, which are limited to narrow specialization). Therefore, when these features emerge, we should be more cautious about organizing the educational process in higher education institutions. This study is characterized by the fact that the author provides a rational for the praxeo-dynamic approach from the point of view of achievements of modern humanitarian knowledge. It allows educators to plan the actions of future teachers, which are aimed at the formation of their readiness for spiritual-moral development of primary schoolchildren. It also gives the opportunity to develop the abilities, which taken in a system, can affects this readiness. The results of this study can be used in the educational process of institutions of higher education in terms of improving teachers’ pedagogical skills in the system of postgraduate pedagogical education, in the process of design of compulsory and optional pedagogical courses while training students of the specialty “Primary Education”. Using a praxeo-dynamic approach to the improvement of future teacher's readiness for the primary schoolchild’s spiritual-moral development the following aspects should be taken into account: moral attitudes (restraint, compassion) and four emotional types of intelligence (according to T. Bradberry and D. Greaves), which have a direct impact on the productivity, effectiveness and dynamism of this area of professional activity. It is also important to use hands-on exercises, which help to increase emotional intelligence.
Performance Analysis of Human Detection and Tracking in Changing Illumination

Understanding Business Strategy Factors that Support or Impede Moving Business Capabilities to a Cloud Environment in the Investment Services Industry

This research investigates how the business strategy factors for South African organizations either support or impede moving business capabilities to a Cloud Computing (CC) environment. In particular, the research considers larger organizations within the investment services industry. By performing a qualitative study the research investigates the various business and Information Technology (IT) strategies. The various CC options are then explored to draw a correlation between the business strategy factors and CC. It concludes that cloud computing offers no competitive differentiation for South African investment services organisations. For these organisations, their existing business models remains profitable. Business strategy, therefore, has no compelling reason to consider cloud computing. South African investment services organizations align with their business strategies through the service-level method, which cause the IT departments to focus on stability and reliability.
Spacing detection method for shearing interference fringes containing speckle noises

Due to environmental illumination and other factors, actual shearing interference image used to measure the rotation angle contains high-frequency speckle noises. According to the characteristics of shearing interference images, a low-pass filter based on homomorphic filtering principle is selected to filter these images. The desired filtering result can be achieved by adjusting the filter parameters such as the cutoff frequency radius and the order of the filter. The Hilditch thinning algorithm is applied to extract the center of the fringes to calculate the spacing between neighbor fringes. The accuracy of the algorithm is verified by the actual and simulation experiments with the error of fringe spacing detection less than 0.01%.
