Explicating the Implicit: Argument Detection Beyond Sentence Boundaries

ACL 2024long

Detecting semantic arguments of a predicate word has been conventionally modeled as a sentence-level task. The typical reader, however, perfectly interprets predicate-argument relations in a much wider context than just the sentence where the predicate was evoked. In this work, we reformulate the pr…

QASem Parsing: Text-to-text Modeling of QA-based Semantics

EMNLP 2022main

Various works suggest the appeals of incorporating explicit semantic representations when addressing challenging realistic NLP scenarios. Common approaches offer either comprehensive linguistically-based formalisms, like AMR, or alternatively Open-IE, which provides a shallow and partial representat…

QA-Align: Representing Cross-Text Content Overlap by Aligning Question-Answer Propositions

EMNLP 2021main

Multi-text applications, such as multi-document summarization, are typically required to model redundancies across related texts. Current methods confronting consolidation struggle to fuse overlapping information. In order to explicitly represent content overlap, we propose to align predicate-argume…

QANom: Question-Answer driven SRL for Nominalizations

COLING 2020main

We propose a new semantic scheme for capturing predicate-argument relations for nominalizations, termed QANom. This scheme extends the QA-SRL formalism (He et al., 2015), modeling the relations between nominalizations and their arguments via natural language question-answer pairs. We construct the f…
