Fine-Grained Natural Language Inference Based Faithfulness Evaluation for Diverse Summarisation Tasks

1 code implementation27 Feb 2024 Huajian Zhang, Yumo Xu, Laura Perez-Beltrachini

We study existing approaches to leverage off-the-shelf Natural Language Inference (NLI) models for the evaluation of summary faithfulness and argue that these are sub-optimal due to the granularity level considered for premises and hypotheses.

QTSumm: Query-Focused Summarization over Tabular Data

2 code implementations23 May 2023 Yilun Zhao, Zhenting Qi, Linyong Nan, Boyu Mi, Yixin Liu, Weijin Zou, Simeng Han, Ruizhe Chen, Xiangru Tang, Yumo Xu, Dragomir Radev, Arman Cohan

Motivated by this, we define a new query-focused table summarization task, where text generation models have to perform human-like reasoning and analysis over the given table to generate a tailored summary.

Text Summarization with Oracle Expectation

1 code implementation26 Sep 2022 Yumo Xu, Mirella Lapata

Extractive summarization produces summaries by identifying and concatenating the most important sentences in a document.

Text Summarization with Latent Queries

no code implementations31 May 2021 Yumo Xu, Mirella Lapata

The availability of large-scale datasets has driven the development of neural models that create summaries from single documents, for generic purposes.

Generating Query Focused Summaries from Query-Free Resources

1 code implementation ACL 2021 Yumo Xu, Mirella Lapata

The availability of large-scale datasets has driven the development of neural models that create generic summaries from single or multiple documents.

Meta Dialogue Policy Learning

no code implementations3 Jun 2020 Yumo Xu, Chenguang Zhu, Baolin Peng, Michael Zeng

Dialog policy determines the next-step actions for agents and hence is central to a dialogue system.

Bootstrapping a Crosslingual Semantic Parser

1 code implementation Findings of the Association for Computational Linguistics 2020 Tom Sherborne, Yumo Xu, Mirella Lapata

Considering when MT is inadequate, we also find that using our approach achieves parsing accuracy within 2% of complete translation using only 50% of training data.

Query Focused Multi-Document Summarization with Distant Supervision

no code implementations6 Apr 2020 Yumo Xu, Mirella Lapata

We consider the problem of better modeling query-cluster interactions to facilitate query focused multi-document summarization (QFS).

Stock Movement Prediction from Tweets and Historical Prices

1 code implementation ACL 2018 Yumo Xu, Shay B. Cohen

Stock movement prediction is a challenging problem: the market is highly stochastic, and we make temporally-dependent predictions from chaotic data.
