Towards the Development of Speech-Based Measures of Stress Response in Individuals

no code implementations NAACL (CLPsych) 2021 Archna Bhatia, Toshiya Miyatsu, Peter Pirolli

In this paper, we identify and validate features in speech that can be used as indicators of stress response in individuals to develop speech-based measures of stress response.

From Spatial Relations to Spatial Configurations

no code implementations LREC 2020 Soham Dan, Parisa Kordjamshidi, Julia Bonn, Archna Bhatia, Jon Cai, Martha Palmer, Dan Roth

To exhibit the applicability of our representation scheme, we annotate text taken from diverse datasets and show how we extend the capabilities of existing spatial representation languages with the fine-grained decomposition of semantics and blend it seamlessly with AMRs of sentences and discourse representations as a whole.

Adaptation of a Lexical Organization for Social Engineering Detection and Response Generation

no code implementations LREC 2020 Archna Bhatia, Adam Dalton, Brodie Mather, Sashank Santhanam, Samira Shaikh, Alan Zemel, Tomek Strzalkowski, Bonnie J. Dorr

We present a paradigm for extensible lexicon development based on Lexical Conceptual Structure to support social engineering detection and response generation.

Characterization of Divergence in Impaired Speech of ALS Patients

no code implementations WS 2017 Archna Bhatia, Bonnie Dorr, Kristy Hollingshead, Samuel L. Phillips, Barbara McKenzie

Approximately 80{\%} to 95{\%} of patients with Amyotrophic Lateral Sclerosis (ALS) eventually develop speech impairments, such as defective articulation, slow laborious speech and hypernasality.

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).

Compositionality in Verb-Particle Constructions

no code implementations WS 2017 Archna Bhatia, Choh Man Teng, James Allen

We are developing a broad-coverage deep semantic lexicon for a system that parses sentences into a logical form expressed in a rich ontology that supports reasoning.

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.

Augmenting English Adjective Senses with Supersenses

1 code implementation LREC 2014 Yulia Tsvetkov, Nathan Schneider, Dirk Hovy, Archna Bhatia, Manaal Faruqui, Chris Dyer

We develop a supersense taxonomy for adjectives, based on that of GermaNet, and apply it to English adjectives in WordNet using human annotation and supervised classification.

A Unified Annotation Scheme for the Semantic/Pragmatic Components of Definiteness

no code implementations LREC 2014 Archna Bhatia, M Simons, y, Lori Levin, Yulia Tsvetkov, Chris Dyer, Jordan Bender

We present a definiteness annotation scheme that captures the semantic, pragmatic, and discourse information, which we call communicative functions, associated with linguistic descriptions such as {``}a story about my speech{''}, {``}the story{''}, {``}every time I give it{''}, {``}this slideshow{''}.
