The rapid growth in the use of social media has given rise to several new types of text analytics, such as buzz monitoring, opinion mining, and Sentiment Analysis (SA). SentiMetrix©, Inc., a company specializing in Sentiment Analysis, has built a scalable modular SentiGrade™ engine that provides near-real-time analysis and precise granular sentiment scores for textual documents across a variety of domains. SentiGrade™, combining several open-source components with proprietary technology developed by the SentiMetrix© team, utilizes in-depth analysis of the grammatical structure of each sentence and applies human-trained models to quantify the sentiment towards multiple topics. The engine was expanded to incorporate new TAPIR algorithms to better accommodate the needs of the psychology-related subject and the project.
