Introduce two text summarization papers

[nguyentthong]

Hello,

Thank you for your comprehensive and wonderful survey.

Would you mind adding 2 papers about text summarization?

Paper 1: Enriching and Controlling Global Semantics for Text Summarization

Accepted at EMNLP 2021

The paper proposes to fuse global semantics of neural topic model and hidden representation of language model to improve document summarization quality.

Paper 2: Improving Neural Cross-Lingual Summarization via Employing Optimal Transport Distance for Knowledge Distillation

This work proposes a method to distill knowledge from monolingual summarization model into cross-lingual summarization model.
