ML Powered Sentiment Analysis for a Medical Research Organization

Challenge

The client organized an employee training session and conducted a feedback survey to gauge satisfaction levels regarding the training. The survey generated a large amount of data, making manual analysis impractical. Therefore, the client sought to implement a machine learning solution for sentiment analysis to automate and streamline the task.

Solution

IT Convergence conducted thorough testing of various machine learning models in the Python library to identify the most suitable option to perform sentiment analysis. After rigorous evaluation, we shortlisted two machine learning analysis models as they fit the requirements. Subsequent testing with a small dataset revealed that one of them consistently delivered more accurate results, leading to its selection.

The data underwent a cleaning process to address formatting issues and the model analyzed the data, accurately classifying as positive, neutral, and negative sentiments. We created a word cloud, where the size of each word indicated its frequency within the dataset. The client could now visualize the most important words in the survey and identify patterns that indicated sentiment. This information was presented through visualizations on a custom Tableau dashboard, providing an accurate representation of the sentiment analysis models and results.
