IVR call records are meticulously analyzed to help with optimization of the IVR system in an effort to ensure that maximum calls complete at the IVR itself, leaving no room for the need for a call-center.
Sentiment Analysis
Sentiment analysis is the analysis of people’s opinions, sentiments, evaluations, appraisals, attitudes, and emotions in relation to entities such as individuals, products, events, services, organizations, and topics. It is achieved by classifying the observed expressions as opinions that may be positive or negative.
Titanic Data Analysis
Titanic was one of the most colossal disasters in the history of mankind, and it happened because of both natural events and human mistakes. The objective of this project is to analyze multiple Titanic data sets to generate essential insights pertaining to age, gender, survived, class, and embarked.
Crime Analysis
