Dual Memory Network Model for Biased Product Review Classification
TLDR
A dual user and product memory network (DUPMN) model is proposed to learn user profiles and product reviews using separate memory networks and the two representations are used jointly for sentiment prediction. Expand
Implicit Discourse Relation Identification for Open-domain Dialogues
TLDR
A method to automatically extract the implicit discourse relation argument pairs and labels from a dataset of dialogic turns is proposed, resulting in a novel corpus of discourse relation pairs, the first of its kind to attempt to identify the discourse relations connecting the dialogicturns in open-domain discourse.

TLDR
A dual user and product memory network (DUPMN) model is proposed to learn user profiles and product information for reviews classification using separate memory networks and the two representations are used jointly for sentiment analysis. Expand
EventPlus: A Temporal Event Understanding Pipeline
TLDR
EventPlus as the first comprehensive temporal event understanding pipeline provides a convenient tool for users to quickly obtain annotations about events and their temporal information for any user-provided document. Expand
HyperExpan: Taxonomy Expansion with Hyperbolic Representation Learning
TLDR
A taxonomy expansion algorithm that seeks to preserve the structure of a taxonomy in a more expressive hyperbolic embedding space and learn to represent concepts and their relations with a Hyperbolic Graph Neural Network (HGNN). Expand
