NLP Seminar: Emotion Ranking and Emotion Cause Detection from Text

Yulan He, full professor at University of Warwick, UK, will give a talk at University of Copenhagen as part of the NLP Seminar Series, funded by CCC. The talk will start at 17:00, there will be refreshments from 16:30.

Title

Emotion Ranking and Emotion Cause Detection from Text

Abstract

Text might contain or evoke multiple emotions with varying intensities. Traditional approaches typically cast the problem of detecting multiple emotions from text as multi-label classification. This talk will first present a novel ranking-based approach to generate a ranked list of relevant emotions where top-ranked emotions are more intensely associated with text compared to lower ranked emotions. Furthermore, since emotions might be evoked by different hidden topics, it is important to unveil and incorporate such topical information to understand how the emotions are evoked. A novel neural network approach with topical information incorporated will be discussed for relevant emotion ranking. Finally, the problem of identifying the reasons behind a certain emotion expressed in text can be framed as a reading comprehension task and a new approach based on memory networks will be presented for emotion cause detection from text.
