Train a Naive Bayes model on the frequent features. A Naïve Bayes model uses the Naïve Bayes theorem which is based on an event occurring given that another event has already occurred. The naive Bayes classifier uses the Bayes Theorem. It predicts membership probabilities for each category such as the probability that a given record or data point belongs to a particular group. The class that is selected as the most likely class is the one with maximum posterior probability. In this model, we applied the Bernoulli Naïve Bayes algorithm which analyzes features in binary form. The model was evaluated using a confusion matrix; which shows how the model performed in predicting the polarity of the test reviews. The metrics for that include accuracy, Kappa, sensitivity, and specificity. Accuracy: The was able to predict correctly 79% of the new reviews data. Kappa: The model had 57.99% agreement with the baseline random classifier, this shows that our model agrees with the ground truth

An analysis to investigate whether people with long last names also tend to have long first names The whole analysis is targeted at investigating the relationship between the length of the Arabic first name and the length of the Arabic last name. The analysis begins with dot plots of two variables namely; “Fname” which stands for first name and “Lname” which stands for last name. The dot plot shows that the two variables had no relationship at all. The plotted points indicate that the length of the first name was as long as that of the first name but there was no clear trend of the names. The correlation test confirms this assertion with a very small estimated correlation coefficient. The regression model also confirms this with a huge p-value. Therefore it’s statistically correct to state that people with long last names don’t necessarily have long first names.
