Overview of Robust and Multilingual Automatic Evaluation Metrics for Open-Domain Dialogue Systems at DSTC 11 Track 4

1 code implementation22 Jun 2023 Mario Rodríguez-Cantelar, Chen Zhang, Chengguang Tang, Ke Shi, Sarik Ghazarian, João Sedoc, Luis Fernando D'Haro, Alexander Rudnicky

The advent and fast development of neural networks have revolutionized the research on dialogue systems and subsequently have triggered various challenges regarding their automatic evaluation.

DMRST: A Joint Framework for Document-Level Multilingual RST Discourse Segmentation and Parsing

1 code implementation CODI 2021 Zhengyuan Liu, Ke Shi, Nancy F. Chen

While previous work significantly improves the performance of RST discourse parsing, they are not readily applicable to practical use cases: (1) EDU segmentation is not integrated into most existing tree parsing frameworks, thus it is not straightforward to apply such models on newly-coming data.

Conditional Neural Generation using Sub-Aspect Functions for Extractive News Summarization

no code implementations Findings of the Association for Computational Linguistics 2020 Zhengyuan Liu, Ke Shi, Nancy F. Chen

In this paper, we propose a neural framework that can flexibly control summary generation by introducing a set of sub-aspect functions (i. e. importance, diversity, position).
