Abstract: In this talk, we describe our long-standing work on sentiment and emotion analysis, and also the use of NLP for mental health monitoring. The last mentioned is a stigma that society prefers to keep under cover, but with hazardous consequences. We describe our contribution to the techniques of sentiment and emotion analysisoften multimodal, multitasking, and multilingual. Such techniques have also proven useful in monitoring mental distress and providing positivity and hope through NLP agents. The work reported is the result of efforts of generations of students, and has found a place in top journals and conferences.
