Entity Enhancement for Implicit Discourse Relation Classification in the Biomedical Domain

no code implementations ACL 2021 Wei Shi, Vera Demberg

Implicit discourse relation classification is a challenging task, in particular when the text domain is different from the standard Penn Discourse Treebank (PDTB; Prasad et al., 2008) training corpus domain (Wall Street Journal in 1990s).

Exploring the Potential of Lexical Paraphrases for Mitigating Noise-Induced Comprehension Errors

no code implementations18 Jul 2021 Anupama Chingacham, Vera Demberg, Dietrich Klakow

We evaluate the intelligibility of synonyms in context and find that choosing a lexical unit that is less risky to be misheard than its synonym introduced an average gain in comprehension of 37% at SNR -5 dB and 21% at SNR 0 dB for babble noise.

Time-Aware Ancient Chinese Text Translation and Inference

1 code implementation7 Jul 2021 Ernie Chang, Yow-Ting Shiue, Hui-Syuan Yeh, Vera Demberg

In this paper, we aim to address the challenges surrounding the translation of ancient Chinese text: (1) The linguistic gap due to the difference in eras results in translations that are poor in quality, and (2) most translations are missing the contextual information that is often very crucial to understanding the text.

Jointly Improving Language Understanding and Generation with Quality-Weighted Weak Supervision of Automatic Labeling

no code implementations EACL 2021 Ernie Chang, Vera Demberg, Alex Marin

Neural natural language generation (NLG) and understanding (NLU) models are data-hungry and require massive amounts of annotated data to be competitive.

Neural Data-to-Text Generation with LM-based Text Augmentation

no code implementations EACL 2021 Ernie Chang, Xiaoyu Shen, Dawei Zhu, Vera Demberg, Hui Su

Our approach automatically augments the data available for training by (i) generating new text samples based on replacing specific values by alternative ones from the same category, (ii) generating new text samples based on GPT-2, and (iii) proposing an automatic method for pairing the new text samples with data samples.

Diverse and Relevant Visual Storytelling with Scene Graph Embeddings

no code implementations CONLL 2020 Xudong Hong, Rakshith Shetty, Asad Sayeed, Khushboo Mehra, Vera Demberg, Bernt Schiele

A problem in automatically generated stories for image sequences is that they use overly generic vocabulary and phrase structure and fail to match the distributional characteristics of human-generated text.

Crowdsourcing Discourse Relation Annotations by a Two-Step Connective Insertion Task

no code implementations WS 2019 Frances Yung, Vera Demberg, Merel Scholman

The perspective of being able to crowd-source coherence relations bears the promise of acquiring annotations for new texts quickly, which could then increase the size and variety of discourse-annotated corpora.

A Hybrid Model for Globally Coherent Story Generation

no code implementations WS 2019 Fangzhou Zhai, Vera Demberg, Pavel Shkadzko, Wei Shi, Asad Sayeed

The model exploits a symbolic text planning module to produce text plans, thus reducing the demand of data; a neural surface realization module then generates fluent text conditioned on the text plan.

Verb-Second Effect on Quantifier Scope Interpretation

no code implementations WS 2019 Asad Sayeed, Matthias Lindemann, Vera Demberg

Sentences like {``}Every child climbed a tree{''} have at least two interpretations depending on the precedence order of the universal quantifier and the indefinite.

Toward Bayesian Synchronous Tree Substitution Grammars for Sentence Planning

no code implementations WS 2018 David M. Howcroft, Dietrich Klakow, Vera Demberg

Developing conventional natural language generation systems requires extensive attention from human experts in order to craft complex sets of sentence planning rules.

Acquiring Annotated Data with Cross-lingual Explicitation for Implicit Discourse Relation Classification

no code implementations WS 2019 Wei Shi, Frances Yung, Vera Demberg

Implicit discourse relation classification is one of the most challenging and important tasks in discourse parsing, due to the lack of connective as strong linguistic cues.

Do Speakers Produce Discourse Connectives Rationally?

no code implementations WS 2018 Frances Yung, Vera Demberg

A number of different discourse connectives can be used to mark the same discourse relation, but it is unclear what factors affect connective choice.
