A Graph Oriented Based Recommender System for Financial Products and Services

Review Article of International Journal of Service Science and Management A Graph Oriented Based Recommender System for Financial Products and Services Olakunle Temitope., Awodele, O., Adekunle, Y.A., Eze, M.O., *Ebiesuwa Seun Department of Computer Science, Babcock University, Nigeria Recommender Systems are intelligent applications designed to assist the user in a decision-making process whereby user wants to choose one item amongst the potentially overwhelming set of alternative products or services. This research is aimed at developing an intelligent recommender system that provides high quality recommendations in the financial domain. Hashed and anonymized datasets (which are account statements) were acquired from online sources and bank customers. The acquired data was pre-processed using the Microsoft Excel 2016 and WEKA 3.8.3 data mining software. The K-nearest neighbor (KNN) algorithm was used to classify the dataset and train the model. The trained model was used to develop a recommender system using the Java 2 platform Enterprise Edition (J2EE). For effective management of the data and consideration of rapid increase in data growth, a graph-oriented database approach was proposed and utilized. The database management system used was the Neo4j. From the evaluation of the algorithms implemented in the recommender system taxonomy, the KNN algorithm recorded the best performance building the model in 0.3seconds with an accuracy of 89.8%. The fuzzy decision tree algorithm performed second best building the model within 0.48 seconds with an accuracy of 62.8%. The decision table algorithm performed poorly building the model in 3.9 seconds with an accuracy of 53%. However, the baseline accuracy of the dataset used was evaluated to be 62.75% of accuracy in 0.4 seconds. It is therefore recommended, as proposed in this study that the graph technology be used in developing recommender systems especially for institutions with massively growing data like the financial institutions. In addition, bank products ...

Assessment of Airport Taxi Dispatching Based on Psychological Account Principle Decision Model — A Case Study of Shanghai pudong Airport

Research Article of International Journal of Service Science and Management Assessment of Airport Taxi Dispatching Based on Psychological Account Principle Decision Model -- A Case Study of Shanghai pudong Airport Zhong Zheng1*, Yanlin Li2, Qing Xu3, Yun Tang1, Hao Zhang1 1College of Electrical Engineering & New Energy, China Three Gorges University, Yichang, 443002, China. 2College of Science, China Three Gorges University, Yichang, 443002, China. 3College of Foreign Languages, China Three Gorges University, Yichang, 443002, China. In this paper, a decision model based on psychological account principle and a queuing theory model based on (M/ M/1) system are established to solve the problem of providing more reasonable choices for airport taxi drivers. Combined with reverse test method, control variable method and other methods to analyze the problem. Taking Shanghai pudong airport as an example, the error coefficient of critical decision value is calculated to be around 0.13, and the model is reasonable. It is concluded that weather has great influence on decision making and seasonal change has little influence on decision making. Keywords: Psychological account principle; Reverse test; Control variable method ...

Airport Taxi Management Based on Dynamic Decision and Multi-objective Programming Model

Research Article of International Journal of Service Science and Management Airport Taxi Management Based on Dynamic Decision and Multi-objective Programming Model Hairui Zhang1*, Zhong Zheng2, Yu Cao1 1College of Science, China Three Gorges University, Yichang, 443002, China. 2College of Electrical Engineering & New Energy, China Three Gorges University, Yichang, 443002, China. Nowadays major airports often have a large number of passengers and vehicles stranded, resulting in inefficient airport operations. In order to solve this problem, this article aims at the decision-making problems that airport taxi drivers face after sending passengers to the airport, and the problem of setting up the boarding point of the airport by analyzing the influencing mechanism of factors related to taxi driver decisions, and considering the changing rules of airport passengers and the benefits of taxi drivers, we have established Driver’s choice decision model based on time periods and Multi-objective programming model based on queuing theory. The model established in this paper can greatly alleviate the airport’s load-bearing pressure, improve the airport’s overall boarding efficiency under the condition that the taxi driver’s income is balanced, and provide a theoretical basis for the systematization of airport taxi queuing. Keywords: Multi-objective programming; Queuing theory; Periodic dynamic decision mode; Vehicle threshold ...

Assessment of Nurses’ Knowledge and Utilization of Evidence Based Practice and its Associated Factors

Research Article of International Journal of Service Science and Management Assessment of Nurses’ Knowledge and Utilization of Evidence Based Practice and its Associated Factors in Selected Hospitals of three Zones of Southern Ethiopia, 2017 Teshome Habte Wurjine1*, Eyoel Abate Dade2 1Department of Nursing and Midwifery, College of Health Sciences, Addis Ababa University; 2Saint Paul Hospital Millennium Medical College Background: Evidence based practice is conscientious, clear and judicious use of current best evidence in making decisions about the care of patient. It is becoming a worldwide concern for nurses, doctors and administrators at various level of health care settings considered as critical element to improve quality of health care services. Currently one of the major barriers to utilize Evidence-based practice is knowledge deficit especially in developing countries like Ethiopia. Objective: the aim of this study was to assess nurses’ knowledge and utilization of evidence-based practice and its associated factors in selected hospitals of three zones of SNNPR, South Ethiopia. Methods: setting: the study was carried out in a sample of three zonal and secondary hospitals because evidence based practice are more implemented at hospital settings. Study design and period: Facility-based descriptive cross-sectional study design was conducted among nurses working in selected hospitals of three zones of south region from March 30 to May 1, 2017. A total of 208 nurses answered a self-reported questionnaire and selected by using convenient sampling technique. Descriptive statistics, Bi-variate and multivariate logistic regression were used to analyze the data. A statistical significance was declared at p value<0.05. Primary and secondary outcome: The primary outcome was nurses’ knowledge and utilization of evidence based practice in making decision in the nursing care of patients and secondary outcome of individual aspect of nurses experience EBP in decision making process in the patient care. Results: Sample of the study gathered ...
