A SYSTEM AND METHOD FOR ANOMALY DETECTION BASED ON DIFFERENTIAL OF SENTIMENT SCORE

A System (100) and a method (200) for anomaly detection based on differential of sentiment score, comprises of: a user interface unit (102) for accessing a social media account upon successful authentication of a user and selecting a specific topic for anomaly detection; a text extraction unit (104) for collecting a plurality of data to extract text content from each of the collected plurality of data; a sentiment processing unit (106) for processing the collected data to calculate a sentiment score of each feed based on a plurality of parameters and stored in a database (108); a classification unit (110) for classifying the processed data into positive, negative and neutral percentage of posts; a calculation unit (112) for calculating a differential of sentiment score based on historical data stored in the database; and an anomaly detection unit (114) for detecting anomaly in the differential of the sentiment score.
