• 1 Introduction
• 2 Background

• EMNLP 2017
• https://arxiv.org/pdf/1906.04943.pdf
• learn temporal relations in natural language text

1 Introduction

• timex extraction: easy
• temporal relation: hard
• directed temporal graph
  • nodes represent temporal entities
  • edges represent TLINKs
  • E-E TLINKs: events
  • T-T, E-T
  • focus on the E-E TLINKs
• want to construct a temporal graph as in Fig.1
  

2 Background

• reduced set of relation types
• ambiguity
• TE3, temporal awareness
