Bruteporter: a hybrid approach
Статья научная
Stemming fetches the main root word from the inflectional words called stem. Stem gives different meaning when suffix or prefix is added to it. The stem need not give perfect meaning. Lemmatization gives lemma from inflectional words. Lemma should give meaning that in the dictionary form. Natural Language processing, Information retrieval, Text mining are the areas which use the stemming as preprocessing step. Through stemming, the size of the document can be reduced and ambiguity is also removed. It makes the work easy for other process likes information retrieval, semantic analysis, text categorization etc. Though there is a need for linguistic improvements in the existing stemming algorithms, all these algorithms fail in some cases to give an exact Root word and are not able to handle informal verbs. Hence, Bruteporter Hybrid approach is proposed in order to improve the linguistic process of stemming in English Texts. It combines the Wordnet and Modified Porter Algorithm. A Wordnet is a lexical dictionary created by linguistics people. Modified porter algorithm has both suffix removal and suffix substitution functionality. This proposed approach can extract root word from both inflectional words and informal verbs. In this paper, Experiment is conducted on proposed algorithm and the accuracy is calculated.

Change Impact Identification in Object-Oriented System: Dependence Graph Approach
Статья научная
The development of software products consumes a lot of time and resources. On the other hand, these development costs are lower than maintenance costs, which represent a major concern, specially, for systems designed with recent technologies. Systems modification should be taken rigorously, and change effects must be considered. The need to offer tools allowing on the one hand, to explain the mechanisms of changes at the source code level, and on the other hand, to reduce the effort as well as the cost of maintenance, is affirmed more and more. We propose in this article an approach based on dependence graph to identify change impact of object-oriented systems. The analysis of change ripple effect is made on the dependence graph representing the considered system. The identification at graph level of maximum range of change ripple effect will enable us to know consequences change at code source of system. This knowledge will enable us to estimate the change cost and to make a compromise between the various suggested changes. Finally, to concretize this study we produced a tool and tested our approach on certain systems.

Classification of Coronary Artery Disease Using Different Machine Learning Algorithms
Статья научная
Coronary Artery Disease (CAD) takes place in the category of fatal diseases resulting in death in our country and around the world. Each year about 340 thousand patients lost their lives due to CAD in Turkey. Early diagnosis is essential to reduce risk and prolong lifetime of these patients for diseases that require long-term treatment having death risk like CAD. For this reason, classification of CAD by using medical data processing and machine learning algorithms are important in order to develop assistive or expert systems for physicians. In this study, five different machine learning algorithms were applied to estimate whether patients in the Z-Alizadeh Sani data set extracted from the UCI machine learning pool are CAD. Accuracy, precision, recall, specificity and F1 score were compared as classification performance indicators to evaluate decision tree, random forest (RF), support vector machines (SVM), nearest neighborhood (k-NN) and multi-layer sensor (MLP) methods. According to the evaluation results, the MLP method gave high classification accuracy with 90%. It also appears that RF performs relatively better than other metrics. This results, show that these classification algorithms can be use for helping healthcare systems.

Classroom Management Strategies and Academic Performance of Junior High School Students
Статья научная
The study examined the influence of classroom management strategies of Junior High School teachers on the academic performance of students in the Ashanti Akim North District. The descriptive survey design was used for the study. One hypothesis and two research questions were developed to guide the study. Multistage sampling technique was used to select 48 teachers and 297 year two students to respond to the Behaviour and Instructional Management Scale (BIMS). Test scores in English Language, Integrated Science, Mathematics and Social Studies were used to measure students’ academic performance. The statistical tools used to analyse the data collected were means, standard deviation, Pearson’s Product Moment Correlation Coefficient (PPMCC) and Multiple Regression. The findings revealed that both students and teachers identified good relationship and reinforcement as the mostly used classroom management strategies. It was found that a significant positive relationship existed between reinforcement and antecedent as classroom management schemes and students’ academic performance. However, good relationship and punishment as classroom management strategies did not have a positive relationship with the academic performance of students. It is recommended that teachers should use reinforcement and antecedent strategies frequently in their classrooms since they play a dual role of managing behaviour and predicting the academic performance of students. Good relationship as a classroom management strategy should be cautiously used because it could potentially be misinterpreted or abused and can lead to low academic performance. Using punishment as a classroom management strategy should be avoided as its use hinders academic performance of students.

Comparative Analysis of Two Programming Platforms for Beginners: Python and Scratch
Статья научная
This research paper conducts a comparative analysis of Python and Scratch, exploring their strengths and weaknesses in introductory programming education. While Scratch serves as an excellent starting point, it has limitations, prompting discussions about its suitability for all learners. Some argue that starting with Scratch facilitates a smoother transition into Python, while others suggest its effectiveness in attracting beginners to computer science. The study, conducted over 12 weeks among beginners in a Nigerian higher institution, aims to assess factors such as ease of learning, versatility, community support, and real-world application on both platforms. The first 4 weeks, participants were introduced to Scratch, then were introduced to Python from week 5 to 8 and finally week 9 to 12 were to work on projects and compare both platforms. The research delves into the experiences of participants lacking prior programming experience, emphasizing the exploration of thematic analysis, System Usability Scale (SUS) scores and individual responses. A total of four evaluations were carried out. Results from the thematic analysis of the 1st evaluation using thematic analysis reveals that Scratch has the ability to foster computational thinking. The 2nd evaluation reveals that Scratch is preferred for tasks such as game development which has the ability to further deepen their programming experience. In the third evaluation, 46.3% of the participants agreed that experience gained from Scratch was helpful in learning Python while 70% agreed to some or a great extent that knowledge and skills acquired from learning Scratch was transferable to learning Python. The fourth evaluation was to understand the ease of use of Scratch versus Python using SUS. The results from SUS notably reveal that the limited number of female participants showed intriguing preferences, with a lone female participant indicating a higher preference for Scratch. However, examining individual responses revealed a consistent outlier, with all participants expressing a higher preference for using Python more frequently than Scratch, despite their initial exposure to both platforms. This research suggests that the choice between Python and Scratch goes beyond syntax preferences, involving pedagogical strategies and the learning experiences each platform offers. This research contributes insights into the effectiveness of Scratch and Python in an educational setting, offering a nuanced understanding of the preferences and experiences of beginners. The findings underscore the importance of considering not only platform features but also individual learning experiences and pedagogical strategies in shaping programming education for novices.

Computer Aided Instruction for Literature Courses Teaching
Статья научная
A majority of domestic universities currently possess conditions of carrying out computer aided instruction, however, most of them are immersed in pure applications of multimedia classroom systems. In such application environment, teachers of literature courses generally have bias on understanding of multimedia, thus they pay more attentions to application of multimedia teaching tools and ignore the effective combination of multimedia technology and literature courses with its own characteristics. Literature courses primarily allow students to capture the beauty of Chinese language and its styles through permutations and combinations of them, and then enjoy pleasure of character plots, deep thoughts and feelings and so on. Based on this understanding, computer-assisted instruction should reasonably arrange proportion of multimedia elements: text, images, audio, video and others. Meanwhile, education of magnetic personality of teachers and predominance of teachers during teaching process should not be neglected. At last but not least, proper body language, fine grasp of the classroom rhythm and suitable display of multimedia elements can dramatically improve the effectiveness of delivery, and then achieve the purpose of humane education.
