Japanese Zero Anaphora Resolution Can Benefit from Parallel Texts Through Neural Transfer Learning

no code implementations Findings (EMNLP) 2021 Masato Umakoshi, Yugo Murawaki, Sadao Kurohashi

Parallel texts of Japanese and a non-pro-drop language have the potential of improving the performance of Japanese zero anaphora resolution (ZAR) because pronouns dropped in the former are usually mentioned explicitly in the latter.

Latent Geographical Factors for Analyzing the Evolution of Dialects in Contact

no code implementations EMNLP 2020 Yugo Murawaki

Analyzing the evolution of dialects remains a challenging problem because contact phenomena hinder the application of the standard tree model.

Principal Component Analysis as a Sanity Check for Bayesian Phylolinguistic Reconstruction

1 code implementation29 Feb 2024 Yugo Murawaki

Bayesian approaches to reconstructing the evolutionary history of languages rely on the tree model, which assumes that these languages descended from a common ancestor and underwent modifications over time.

Addressing Segmentation Ambiguity in Neural Linguistic Steganography

1 code implementation12 Nov 2022 Jumon Nozaki, Yugo Murawaki

Previous studies on neural linguistic steganography, except Ueoka et al. (2021), overlook the fact that the sender must detokenize cover texts to avoid arousing the eavesdropper's suspicion.

Frustratingly Easy Edit-based Linguistic Steganography with a Masked Language Model

1 code implementation NAACL 2021 Honai Ueoka, Yugo Murawaki, Sadao Kurohashi

With advances in neural language models, the focus of linguistic steganography has shifted from edit-based approaches to generation-based ones.

Native-like Expression Identification by Contrasting Native and Proficient Second Language Speakers

no code implementations COLING 2020 Oleksandr Harust, Yugo Murawaki, Sadao Kurohashi

We propose a novel task of native-like expression identification by contrasting texts written by native speakers and those by proficient second language speakers.

Building a Japanese Typo Dataset from Wikipedia's Revision History

no code implementations ACL 2020 Yu Tanaka, Yugo Murawaki, Daisuke Kawahara, Sadao Kurohashi

User generated texts contain many typos for which correction is necessary for NLP systems to work.

Adapting BERT to Implicit Discourse Relation Classification with a Focus on Discourse Connectives

no code implementations LREC 2020 Yudai Kishimoto, Yugo Murawaki, Sadao Kurohashi

BERT, a neural network-based language model pre-trained on large corpora, is a breakthrough in natural language processing, significantly outperforming previous state-of-the-art models in numerous tasks.

Minimally Supervised Learning of Affective Events Using Discourse Relations

no code implementations IJCNLP 2019 Jun Saito, Yugo Murawaki, Sadao Kurohashi

Recognizing affective events that trigger positive or negative sentiment has a wide range of natural language processing applications but remains a challenging problem mainly because the polarity of an event is not necessarily predictable from its constituent words.

On the Definition of Japanese Word

no code implementations24 Jun 2019 Yugo Murawaki

The annotation guidelines for Universal Dependencies (UD) stipulate that the basic units of dependency annotation are syntactic words, but it is not clear what are syntactic words in Japanese.

Bayesian Learning of Latent Representations of Language Structures

no code implementations CL 2019 Yugo Murawaki

We borrow the concept of representation learning from deep learning research, and we argue that the quest for Greenbergian implicational universals can be reformulated as the learning of good latent representations of languages, or sequences of surface typological features.

Analyzing Correlated Evolution of Multiple Features Using Latent Representations

1 code implementation EMNLP 2018 Yugo Murawaki

Statistical phylogenetic models have allowed the quantitative analysis of the evolution of a single categorical feature and a pair of binary features, but correlated evolution involving multiple discrete features is yet to be explored.

Diachrony-aware Induction of Binary Latent Representations from Typological Features

no code implementations IJCNLP 2017 Yugo Murawaki

Although features of linguistic typology are a promising alternative to lexical evidence for tracing evolutionary history of languages, a large number of missing values in the dataset pose serious difficulties for statistical modeling.

Contrasting Vertical and Horizontal Transmission of Typological Features

no code implementations COLING 2016 Kenji Yamauchi, Yugo Murawaki

Linguistic typology provides features that have a potential of uncovering deep phylogenetic relations among the world{'}s languages.

Wikification for Scriptio Continua

no code implementations LREC 2016 Yugo Murawaki, Shinsuke Mori

To address this problem, we propose to define a separate task that directly links given texts to an external resource, that is, wikification in the case of Wikipedia.
