Sprucing up Supersenses: Untangling the Semantic Clusters of Accompaniment and Purpose

no code implementations COLING (LAW) 2020 Jena D. Hwang, Nathan Schneider, Vivek Srikumar

We reevaluate an existing adpositional annotation scheme with respect to two thorny semantic domains: accompaniment and purpose.

K-SNACS: Annotating Korean Adposition Semantics

no code implementations DMR (COLING) 2020 Jena D. Hwang, Hanwool Choe, Na-Rae Han, Nathan Schneider

While many languages use adpositions to encode semantic relationships between content words in a sentence (e. g., agentivity or temporality), the details of how adpositions work vary widely across languages with respect to both form and meaning.

Penguins Don't Fly: Reasoning about Generics through Instantiations and Exceptions

no code implementations23 May 2022 Emily Allaway, Jena D. Hwang, Chandra Bhagavatula, Kathleen McKeown, Doug Downey, Yejin Choi

However, they are not universally true -- while sparrows and penguins are both birds, only sparrows can fly and penguins cannot.

The Abduction of Sherlock Holmes: A Dataset for Visual Abductive Reasoning

no code implementations10 Feb 2022 Jack Hessel, Jena D. Hwang, Jae Sung Park, Rowan Zellers, Chandra Bhagavatula, Anna Rohrbach, Kate Saenko, Yejin Choi

We present Sherlock, an annotated corpus of 103K images for testing machine capacity for abductive reasoning beyond literal image contents.

Delphi: Towards Machine Ethics and Norms

no code implementations14 Oct 2021 Liwei Jiang, Jena D. Hwang, Chandra Bhagavatula, Ronan Le Bras, Maxwell Forbes, Jon Borchardt, Jenny Liang, Oren Etzioni, Maarten Sap, Yejin Choi

We identify four underlying challenges towards machine ethics and norms: (1) an understanding of moral precepts and social norms; (2) the ability to perceive real-world situations visually or by reading natural language descriptions; (3) commonsense reasoning to anticipate the outcome of alternative actions in different contexts; (4) most importantly, the ability to make ethical judgments given the interplay between competing values and their grounding in different contexts (e. g., the right to freedom of expression vs. preventing the spread of fake news).

On-the-Fly Attention Modulation for Neural Generation

no code implementations Findings (ACL) 2021 Yue Dong, Chandra Bhagavatula, Ximing Lu, Jena D. Hwang, Antoine Bosselut, Jackie Chi Kit Cheung, Yejin Choi

Despite considerable advancements with deep neural language models (LMs), neural text generation still suffers from degeneration: the generated text is repetitive, generic, self-contradictory, and often lacks commonsense.

Social Chemistry 101: Learning to Reason about Social and Moral Norms

1 code implementation EMNLP 2020 Maxwell Forbes, Jena D. Hwang, Vered Shwartz, Maarten Sap, Yejin Choi

We present Social Chemistry, a new conceptual formalism to study people's everyday social norms and moral judgments over a rich spectrum of real life situations described in natural language.

COMET-ATOMIC 2020: On Symbolic and Neural Commonsense Knowledge Graphs

no code implementations12 Oct 2020 Jena D. Hwang, Chandra Bhagavatula, Ronan Le Bras, Jeff Da, Keisuke Sakaguchi, Antoine Bosselut, Yejin Choi

Next, we show that ATOMIC 2020 is better suited for training knowledge models that can generate accurate, representative knowledge for new, unseen entities and events.

Analysis of the Penn Korean Universal Dependency Treebank (PKT-UD): Manual Revision to Build Robust Parsing Model in Korean

no code implementations WS 2020 Tae Hwan Oh, Ji Yoon Han, Hyonsu Choe, Seokwon Park, Han He, Jinho D. Choi, Na-Rae Han, Jena D. Hwang, Hansaem Kim

In this paper, we first open on important issues regarding the Penn Korean Universal Treebank (PKT-UD) and address these issues by revising the entire corpus manually with the aim of producing cleaner UD annotations that are more faithful to Korean grammar.

Preparing SNACS for Subjects and Objects

1 code implementation WS 2019 Adi Shalev, Jena D. Hwang, Nathan Schneider, Vivek Srikumar, Omri Abend, Ari Rappoport

Research on adpositions and possessives in multiple languages has led to a small inventory of general-purpose meaning classes that disambiguate tokens.

Coordinate Structures in Universal Dependencies for Head-final Languages

no code implementations WS 2018 Hiroshi Kanayama, Na-Rae Han, Masayuki Asahara, Jena D. Hwang, Yusuke Miyao, Jinho D. Choi, Yuji Matsumoto

This paper discusses the representation of coordinate structures in the Universal Dependencies framework for two head-final languages, Japanese and Korean.

Comprehensive Supersense Disambiguation of English Prepositions and Possessives

1 code implementation ACL 2018 Nathan Schneider, Jena D. Hwang, Vivek Srikumar, Jakob Prange, Austin Blodgett, Sarah R. Moeller, Aviram Stern, Adi Bitan, Omri Abend

Semantic relations are often signaled with prepositional or possessive marking--but extreme polysemy bedevils their analysis and automatic interpretation.

Double Trouble: The Problem of Construal in Semantic Annotation of Adpositions

no code implementations SEMEVAL 2017 Jena D. Hwang, Archna Bhatia, Na-Rae Han, Tim O{'}Gorman, Vivek Srikumar, Nathan Schneider

We consider the semantics of prepositions, revisiting a broad-coverage annotation scheme used for annotating all 4, 250 preposition tokens in a 55, 000 word corpus of English.

Adposition and Case Supersenses v2.6: Guidelines for English

3 code implementations7 Apr 2017 Nathan Schneider, Jena D. Hwang, Vivek Srikumar, Archna Bhatia, Na-Rae Han, Tim O'Gorman, Sarah R. Moeller, Omri Abend, Adi Shalev, Austin Blodgett, Jakob Prange

This document offers a detailed linguistic description of SNACS (Semantic Network of Adposition and Case Supersenses; Schneider et al., 2018), an inventory of 52 semantic labels ("supersenses") that characterize the use of adpositions and case markers at a somewhat coarse level of granularity, as demonstrated in the STREUSLE corpus (https://github. com/nert-nlp/streusle/; version 4. 5 tracks guidelines version 2. 6).

Coping with Construals in Broad-Coverage Semantic Annotation of Adpositions

no code implementations10 Mar 2017 Jena D. Hwang, Archna Bhatia, Na-Rae Han, Tim O'Gorman, Vivek Srikumar, Nathan Schneider

We consider the semantics of prepositions, revisiting a broad-coverage annotation scheme used for annotating all 4, 250 preposition tokens in a 55, 000 word corpus of English.

A corpus of preposition supersenses in English web reviews

no code implementations8 May 2016 Nathan Schneider, Jena D. Hwang, Vivek Srikumar, Meredith Green, Kathryn Conger, Tim O'Gorman, Martha Palmer

We present the first corpus annotated with preposition supersenses, unlexicalized categories for semantic functions that can be marked by English prepositions (Schneider et al., 2015).

PropBank: Semantics of New Predicate Types

no code implementations LREC 2014 Claire Bonial, Julia Bonn, Kathryn Conger, Jena D. Hwang, Martha Palmer

This research focuses on expanding PropBank, a corpus annotated with predicate argument structures, with new predicate types; namely, noun, adjective and complex predicates, such as Light Verb Constructions.

Criteria for Identifying and Annotating Caused Motion Constructions in Corpus Data

no code implementations LREC 2014 Jena D. Hwang, Annie Zaenen, Martha Palmer

While natural language processing performance has been improved through the recognition that there is a relationship between the semantics of the verb and the syntactic context in which the verb is realized, sentences where the verb does not conform to the expected syntax-semantic patterning behavior remain problematic.
