Behavioral Data Analysis in Emotional Intelligence of Social Network Consumers (Published)

Emotional intelligence is both characteristic of personality and intellectual capacity, which a person inherits from the genetic material of its parents and evolves – develops throughout lifetime. It refers to information processing capacity arising from the emotions and their utility to guide action in situations that require activation of the cognitive system. The purpose of the present research work is the application of Machine Learning and Data Mining methods for the evaluation of emotional IQ in a sample of students and social network consumers (age 18-26 years). Understanding how users behave when they connect to social networking sites creates opportunities for better interface design, richer studies of social interactions, and improved design of content distribution systems. The data were collected by completion of the self-report questionnaire Trait Emotional Intelligence (TEIQue) and used for the application of data mining methods. Then the collected data were selected for analysis, with relevant transformations in order to have a suitable form for the implementation of the respective machine learning algorithms included in the software package R. Furthermore, the parameters of the corresponding set of algorithms were determined depending on the case of application to produce inference rules. Some of the algorithms implemented according to specific research questions that were applied, were the classification algorithms (ID3 and J48) for the production of decision trees, regarding the four more general factors (welfare, self-control, emotionality and sociability) and in overall emotional intelligence. The results obtained, after weighing and criteria basis, present consumers’ rates, which in turn analyze the degree of emotional intelligence.

Utilization of Data Mining and Anonymous Communication Techniques for Fraud Detection in Large Scale Business Organisations in Delta State (Published)

This study on utilisation of data mining and anonymous communication techniques for fraud detection in large scale business organisations in Delta State was necessitated by the growing incidence frauds that are crippling businesses and socio-economic development of the state. Two research questions guided the study and two null hypotheses were tested at 0.05 level of significance. Related literature to the study were reviewed. Descriptive survey research design was adopted for the study. The population of the study was 260 accounting staff. A sample size of 160 was selected for the study using simple random sampling technique. A four-point rating scale questionnaire developed by the researchers was used for data collection.  Cronbach Alpha method was used to determine the reliability of the questionnaire and this yielded reliability coefficient values of 0.85 and 0.80 respectively for the sections with an overall reliability of 0.83. Data were analyzed using mean and standard deviation to ascertain the homogeneity of the respondent while t-test and analysis of variance were used to test the hypotheses at 0.05 level of significance. The results showed that the accounting staff lowly utilised data mining and anonymous techniques for fraud detection.  Furthermore, it was found that types and status of organization in NSE significantly influenced respondents’ ratings on the utilization of data mining but did not influence their ratings on utilization of anonymous communications for fraud detection. From the findings of the study, it was concluded that the accounting staff did not utilize forensic auditing investigation techniques for fraud detection in large-scale business organisations as required. Based on the findings, the researcher recommended among others, shareholders and directors of large-scale business organisations should provide regular training on data mining techniques to equip their accounting staff with the relevant and up-to-date skills, abilities, attitude and competences for fraud detection.

A classification model for water quality analysis using decision tree (Published)

A classification algorithm is used to assign predefined classes to test instances for evaluation) or future instances to an application). This study presents a Classification model using decision tree for the purpose of analyzing water quality data from different counties in Kenya. The water quality is very important in ensuring citizens get to drink clean water. Application of decision tree as a data mining method to predict clean water based on the water quality parameters can ease the work of the laboratory technologist by predicting which water samples should proceed to the next step of analysis. The secondary data from Kenya Water institute was used for creation of this model.  The data model was implemented in WEKA software. Classification using decision tree was applied to classify /predict the clean and not clean water. The analysis of water Alkalinity,pH level and conductivity can play a major role in  assessing water quality. Five decision tree classifiers which are J48, LMT, Random forest, Hoeffding tree and Decision Stump were used to build the model and the accuracy compared. J48 decision tree had the highest accuracy of 94% with Decision Stump having the lowest accuracy of 83%.

Data Mining Technology and Its Role in Discovering Financial Fraud (Published)

The basis of any business – the customer database, which provides information about the client relationship with the company. The increasing complexity of organizational processes and rapidly changing business environment led to strong growth in domestic corporate data companies. In this regard, the increasing interest from the point of view of fraud risk assessments are beginning to provide tools such as data mining (Forensic Data Analytics – FDA), which allows you to narrow sample of suspicious transactions while minimizing the volume of checks. For example, in the field of communication in the database stores information about the conclusion of agreements for the use of services, the time of termination of the contract, a region rate, etc. The analysis revealed 7 out of 31 dentists who deliberately overstate the value of work performed by the insurance.

K-means algorithm using the algorithm of k-means as 4 clusters formed:

  • Cluster 1: specialized work using expensive additional procedures, the average age of the client – 25, the average cost of services – $ 715;
  • Cluster 2: minor works without the use of additional procedures, the average age of the client – 21, the average cost of services – $ 286;
  • Cluster 3: Significant work using expensive additional procedures, the average age of the client – 38, the average cost of services – $ 819;
  • Cluster 4: Significant work with cheap additional procedures, the average age of the client – 27, the average cost of services – $ 551.
