Solving NLP Problems through Human-System Collaboration: A Discussion-based Approach
Masahiro Kaneko, Graham Neubig, Naoaki Okazaki
Humans work together to solve common problems by having discussions, explaining, and agreeing or disagreeing with each other. Similarly, if a system can have discussions with human…
Semantic Specialization for Knowledge-based Word Sense Disambiguation
Sakae Mizuki, Naoaki Okazaki
A promising approach for knowledge-based Word Sense Disambiguation (WSD) is to select the sense whose contextualized embeddings computed for its definition sentence are closest to…
DREEAM: Guiding Attention with Evidence for Improving Document-Level Relation Extraction
Youmi Ma, An Wang, Naoaki Okazaki
