Do We Know What We Don’t Know? Studying Unanswerable Questions beyond SQuAD 2.0

no code implementations Findings (EMNLP) 2021 Elior Sulem, Jamaal Hay, Dan Roth

Understanding when a text snippet does not provide a sought after information is an essential part of natural language utnderstanding.

RTE

Capturing the Content of a Document through Complex Event Identification

no code implementations *SEM (NAACL) 2022 Zheng Qi, Elior Sulem, Haoyu Wang, Xiaodong Yu, Dan Roth

We address this task as a pipeline, first predicting whether two granular events mentioned in the text belong to the same complex event, independently of their position in the text, and then using this to cluster them into complex events.

Yes, No or IDK: The Challenge of Unanswerable Yes/No Questions

no code implementations NAACL 2022 Elior Sulem, Jamaal Hay, Dan Roth

For example, given the context “She married a lawyer from New-York.”, we don’t know whether the answer to the question “Did she marry in New York?” is “Yes” or “No”.

Zero-shot Event Extraction via Transfer Learning: Challenges and Insights

no code implementations ACL 2021 Qing Lyu, Hongming Zhang, Elior Sulem, Dan Roth

Event extraction has long been a challenging task, addressed mostly with supervised methods that require expensive annotation and are not extensible to new event ontologies.

Semantic Structural Decomposition for Neural Machine Translation

1 code implementation Joint Conference on Lexical and Computational Semantics 2020 Elior Sulem, Omri Abend, Ari Rappoport

Building on recent advances in semantic parsing and text simplification, we investigate the use of semantic splitting of the source sentence as preprocessing for machine translation.

The Language of Legal and Illegal Activity on the Darknet

2 code implementations ACL 2019 Leshem Choshen, Dan Eldad, Daniel Hershcovich, Elior Sulem, Omri Abend

The non-indexed parts of the Internet (the Darknet) have become a haven for both legal and illegal anonymous activity.

SemEval-2019 Task 1: Cross-lingual Semantic Parsing with UCCA

no code implementations SEMEVAL 2019 Daniel Hershcovich, Zohar Aizenbud, Leshem Choshen, Elior Sulem, Ari Rappoport, Omri Abend

We present the SemEval 2019 shared task on UCCA parsing in English, German and French, and discuss the participating systems and results.

BLEU is Not Suitable for the Evaluation of Text Simplification

1 code implementation EMNLP 2018 Elior Sulem, Omri Abend, Ari Rappoport

BLEU is widely considered to be an informative metric for text-to-text generation, including Text Simplification (TS).

Semantic Structural Evaluation for Text Simplification

1 code implementation NAACL 2018 Elior Sulem, Omri Abend, Ari Rappoport

Current measures for evaluating text simplification systems focus on evaluating lexical text aspects, neglecting its structural aspects.

SemEval 2019 Shared Task: Cross-lingual Semantic Parsing with UCCA - Call for Participation

no code implementations31 May 2018 Daniel Hershcovich, Leshem Choshen, Elior Sulem, Zohar Aizenbud, Ari Rappoport, Omri Abend

Given the success of recent semantic parsing shared tasks (on SDP and AMR), we expect the task to have a significant contribution to the advancement of UCCA parsing in particular, and semantic parsing in general.
