Sentiment Analysis
We carry out research in a range of tasks in sentiment
analysis, including sentiment classification,
emotion ranking, sentiment-topic extraction,
Twitter sentiment analysis, dialogue emotion
detection, emotion cause extraction, aspect-based
sentiment analysis, stance detection and sarcasm
detection.
