Abstract

Cancer is one among leading diseases, which affects millions of people and families around the world. Monitoring the mood of such cancer affected people plays a vital part in their treatment. In recent days, social media provides a platform for many people to share their experiences about the cancer through various blogs and communities. In this study, we intended to analyse moods of various cancer affected patients by collecting tweets from different online cancer supported communities. We employed several text mining and machine learning strategies to perform sentiment analysis on a distributed framework and developed a model for easier and faster analysis. The proposed distributed framework with long short-term memory (LSTM) neural network is an alternative to the conventional sentiment analysis approaches in analysing large volumes of data in a potential flow. The effectiveness of proposed framework was evaluated on the proposed dataset (corpus-1) and other two benchmark datasets like Health news Tweets (corpus-2) and Medical abstracts (corpus-3). The performance of each text mining and classification method was separately evaluated on three datasets and compared to each other. The results proved that the proposed approach performed better among the other methods in terms of both accuracy and execution time.
