Item Open AccessCrime Prediction Using Decision Tree (J48) Classification Algorithm.(International Journal of Computer and Information Technology, 2017) Ivan, Niyonzima; Emmanuel Ahishakiye; Elisha Opiyo Omulo; Danison TaremwaThere had been an enormous increase in the crime in the recent past. Crimes are a common social problem affecting the quality of life and the economic growth of a society. With the increase of crimes, law enforcement agencies are continuing to demand advanced systems and new approaches to improve crime analytics and better protect their communities. Decision tree (J48) applied in the context of law enforcement and intelligence analysis holds the promise of alleviating such problem. Data mining is a way to extract knowledge out of usually large data sets; in other words it is an approach to discover hidden relationships among data by using artificial intelligence methods of which decision tree (J48) is inclusive. The wide range of machine learning applications has made it an important field of research. Criminology is one of the most important fields for applying data mining. Criminology is a process that aims to identify crime characteristics. This study considered the development of crime prediction prototype model using decision tree (J48) algorithm because it has been considered as the most efficient machine learning algorithm for prediction of crime data as described in the related literature. From the experimental results, J48 algorithm predicted the unknown category of crime data to the accuracy of 94.25287% which is fair enough for the system to be relied on for prediction of future crimes. Item Open AccessDeveloping Countries and Blockchain Technology: Uganda’s Perspective(International Journal of Latest Research in Engineering and Technology, 2018) Ivan, Niyonzima; Ruth Wario; Emmanuel AhishakiyeBlockchain is receiving ever-growing attention from research and industry and is considered a breakthrough technology. This paper presents an overview of Blockchain Technology and its potential applications in developing countries especially Uganda. It was noted that these nations have the potential to progress, but do not have adequate access to present day technology, primarily due to lack of infrastructure and thus Blockchain Technology will fill the gaps. Fundamentally, these nations need transparency, security, and accountability in their processes, all of which are cornerstones of Blockchain technology. Finally, this paper reveals that due to the support from both government and non-governmental organizations, and the establishment of the Blockchain Association of Uganda, Uganda is ready for Blockchain Technology. Item Open AccessMobile Enabled Vehicle Tracking System a Case of Long Distance Bus Companies in E. Africa(Journal of Electrical and Electronics Engineering (IOSR-JEEE), 2019) Conrad M., Mubaraka; Ivan, NiyonzimaThe use of Global Positioning System (GPS) has remarkable contribution in tracking human behaviour ranging from stationed persons to those in transit, especially trans-border bus drivers. With the current road Carnegies in E.African routes there suffices need to track vehicles and drivers behavior from a central station. This not only curbs down bribery with traffic officers but also tames bus drivers hence reducing on accident prevalence. A design science research methodology was adopted with six major bus companies and a prototype (Me V track system) developed to assist in this Nobel cause. It was found to be handy in reducing fatal accidents in the region. However the research recommends that in an event that the GPS is incapacitated the SMS enabled notification can be of paramount importance Item Open AccessA Performance Analysis of Business Intelligence Techniques on Crime Prediction(International Journal of Computer and Information Technology, 2017) Ivan, Niyonzima; Emmanuel Ahishakiye; Elisha Opiyo Omulo; Ruth WarioLaw Enforcement agencies are faced with a problem of effectively predicting the likelihood of crime happening given the past crime data which would otherwise help them to do so. There is a need to identify the most efficient algorithm that can be used in crime prediction given the past crime data. In this research, Business intelligence techniques considered was based on supervised learning (Classification) techniques given that labeled training data was available. Four different classification algorithms that is; decision tree (J48), Naïve Bayes, Multilayer Perceptron and Support Vector Machine were compared to find the most effective algorithm for crime prediction. The study used classification models generated using Waikato Environment for Knowledge Analysis (WEKA). Manual method of attribute selection was used; this is because it works well when there is large number of attributes. The dataset was acquired from UCI machine learning repository website with a title ‘Crime and Communities’. The data set had 128 attributes of which 13 were selected for the study. The study revealed that the accuracy of J48, Naïve bayes, Multilayer perceptron and Support Vector Machine (SMO) is approximately 100%, 89.7989%, 100% and 92.6724%, respectively for both training and test data. Also the execution time in seconds of J48, Naïve bayes, Multilayer perceptron and SVO is 0.06, 0.14, 9.26 and 0.66 respectively using windows7 32 bit. Hence, Decision Tree (J48) out performed Naïve bayes, Multilayer perceptron and Support Vector Machine (SMO) algorithms, and manifested higher performance both in execution time and in accuracy. The scope of this project was to identify the most effective and accurate Business intelligence technique that can be used during crime data mining to provide accurate results. Item Open AccessA Secure Application for Information Sharing i n Organizations: A Case Study of Kabale District Local Government(Global Society of Scientific Research and Researchers, 2016) Ivan, Niyonzima; Godfrey, Omoda OnyaitInformation shared is exposed to threats of confidentiality, integrity and availability needed for decision making in org anizations. A case study was carried out at Kabale District local Government where interviews and questionnaires were administered to purposively selected elements of the study. The findings revealed that the information shared within the organization is e xposed to potential threats that can put the organization’s information at a risk of being accessed by unauthorized users. The following factors for securing information were identified and used in the development of a secure application for information sh aring in organizations. These factors include; denying unauthorized staff and other individuals from gaining access to personal data, passwords to be treated as private to the individual, secure disposal of information, paper files to store in secure locat ions and only accessed by those who need to use them. In this application, the information is encoded using crypto graphical methods that cannot be easily intercepted, such that only the intended recipient is able to receive it in its original format for d ecoding. This makes information shared secure. The application was tested and validated by a range of stakeholders and it was found secure. For the future work, a survey will be carried out in a range of organizations in order to develop an improved applic ation for information sharing.
