Speaker: Dr. Tulika Saha, Dept. of Computer Science, University of Liverpool, UK

Date/Time: May 27 16:00:00

Location: Online Seminar

Abstract:
Conversational Natural Language Processing (NLP) is a rapidly growing field with applications ranging from virtual assistants for customer service to personalized assistants. Today\'s talk will explore dialogue systems in several domains and applications such as ecommerce, NLPfor Social Good such as healthcare etc. In this process, the talk aims to highlight three primary modules of a dialogue system, namely Natural Language Understanding, Dialogue Policy Learning, Natural Language Generation. As the eventual evaluators of any dialogue systems are users, sentiment of the user plays an important role and provides additional information apart from semantics to ensure a fulfilling conversational experience. Thus, this talk will also explore how sentiment and multi-modality is incorporated in every module of the dialogue system to learn a richer representation of user needs and queries and to highlight its effect in task-fulfillment.
