Weakly Supervised Subevent Knowledge Acquisition

no code implementations EMNLP 2020 Wenlin Yao, Zeyu Dai, Maitreyi Ramaswamy, Bonan Min, Ruihong Huang

We first obtain the initial set of event pairs that are likely to have the subevent relation, by exploiting two observations that 1) subevents are temporally contained by the parent event, and 2) the definitions of the parent event can be used to further guide the identification of subevents.


Hierarchical Fusion for Online Multimodal Dialog Act Classification

Public opinion is shaped by the information news media provide, and that information in turn may be shaped by the ideological preferences of media outlets.

Discourse Structures Guided Fine-grained Propaganda Identification

1 code implementation28 Oct 2023 Yuanyuan Lei, Ruihong Huang

Hence, we propose to incorporate both local and global discourse structures for propaganda discovery and construct two teacher models for identifying PDTB-style discourse relations between nearby sentences and common discourse roles of sentences in a news article respectively.

RST-style Discourse Parsing Guided by Document-level Content Structures

no code implementations8 Sep 2023 Ming Li, Ruihong Huang

Rhetorical Structure Theory based Discourse Parsing (RST-DP) explores how clauses, sentences, and large text spans compose a whole discourse and presents the rhetorical structure as a hierarchical tree.

Explicitly Capturing Relations between Entity Mentions via Graph Neural Networks for Domain-specific Named Entity Recognition

1 code implementation ACL 2021 Pei Chen, Haibo Ding, Jun Araki, Ruihong Huang

Named entity recognition (NER) is well studied for the general domain, and recent systems have achieved human-level performance for identifying common entity types.

Automatic Data Acquisition for Event Coreference Resolution

1 code implementation EACL 2021 Prafulla Kumar Choubey, Ruihong Huang

We propose to leverage lexical paraphrases and high precision rules informed by news discourse structure to automatically collect coreferential and non-coreferential event pairs from unlabeled English news articles.

Weakly-supervised Fine-grained Event Recognition on Social Media Texts for Disaster Management

1 code implementation4 Oct 2020 Wenlin Yao, Cheng Zhang, Shiva Saravanan, Ruihong Huang, Ali Mostafavi

People increasingly use social media to report emergencies, seek help or share information during disasters, which makes social networks an important tool for disaster management.


A Regularization Approach for Incorporating Event Knowledge and Coreference Relations into Neural Discourse Parsing

no code implementations IJCNLP 2019 Zeyu Dai, Ruihong Huang

We argue that external commonsense knowledge and linguistic constraints need to be incorporated into neural network models for mitigating data sparsity issues and further improving the performance of discourse parsing.

In Plain Sight: Media Bias Through the Lens of Factual Reporting

1 code implementation IJCNLP 2019 Lisa Fan, Marshall White, Eva Sharma, Ruisi Su, Prafulla Kumar Choubey, Ruihong Huang, Lu Wang

The increasing prevalence of political bias in news media calls for greater public awareness of it, as well as robust methods for its detection.

Modeling Document-level Causal Structures for Event Causal Relation Identification

no code implementations NAACL 2019 Lei Gao, Prafulla Kumar Choubey, Ruihong Huang

We aim to comprehensively identify all the event causal relations in a document, both within a sentence and across sentences, which is important for reconstructing pivotal event structures.

Improving Dialogue State Tracking by Discerning the Relevant Context

no code implementations NAACL 2019 Sanuj Sharma, Prafulla Kumar Choubey, Ruihong Huang

Specifically, we use the current user utterance and the most recent system utterance to determine the relevance of a system utterance.

Building Context-aware Clause Representations for Situation Entity Type Classification

1 code implementation EMNLP 2018 Zeyu Dai, Ruihong Huang

Capabilities to categorize a clause based on the type of situation entity (e. g., events, states and generic statements) the clause introduces to the discourse can benefit many NLP applications.

Improving Event Coreference Resolution by Modeling Correlations between Event Coreference Chains and Document Topic Structures

Identifying the Most Dominant Event in a News Article by Mining Event Coreference Relations

no code implementations NAACL 2018 Prafulla Kumar Choubey, Kaushik Raju, Ruihong Huang

Identifying the most dominant and central event of a document, which governs and connects other foreground and background events in the document, is useful for many applications, such as text summarization, storyline generation and text segmentation.

Temporal Event Knowledge Acquisition via Identifying Narratives

Improving Implicit Discourse Relation Classification by Modeling Inter-dependencies of Discourse Units in a Paragraph

no code implementations NAACL 2018 Zeyu Dai, Ruihong Huang

We argue that semantic meanings of a sentence or clause can not be interpreted independently from the rest of a paragraph, or independently from all discourse relations and the overall paragraph-level discourse structure.
