  1. Word Complexity is in the Eye of the Beholder

    2021

    Sian Gooding, Ekaterina Kochmar, Seid Muhie Yimam, Chris Biemann. Proceedings of the 2021 Conference of the North American Chapter of the Association for Computational Linguistics: Human Language Technologies. 2021.

  2. Improving Unsupervised Sparsespeech Acoustic Models with Categorical\n Reparameterization

    2020 · arXiv (Cornell University)

    The Sparsespeech model is an unsupervised acoustic model that can generate\ndiscrete pseudo-labels for untranscribed speech. We extend the Sparsespeech\nmodel to allow for sampling over a random discrete variable, yielding\npseudo-posteriorgrams. The degree of sparsity in this …

  3. Exploring Amharic Hate Speech Data Collection and Classification Approaches

    2023

    In this paper, we present a study of efficient data selection and annotation strategies for Amharic hate speech.We also build various classification models and investigate the challenges of hate speech data selection, annotation, and classification …

  4. Large Language Models Are Overparameterized Text Encoders

    2024 · arXiv (Cornell University)

    Large language models (LLMs) demonstrate strong performance as text embedding models when finetuned with supervised contrastive training. However, their large size balloons inference time and memory requirements. In this paper, we show that by pruning …

  5. How to Compare Things Properly? A Study of Argument Relevance in Comparative Question Answering

    2025

    Irina Nikishina, Saba Anwar, Nikolay Dolgov, Maria Manina, Daria Ignatenko, Artem Shelmanov, Chris Biemann. Proceedings of the 63rd Annual Meeting of the Association for Computational Linguistics (Volume 1: Long Papers). 2025.

  6. Do Supervised Distributional Methods Really Learn Lexical Inference Relations?

    2015

    Omer Levy, Steffen Remus, Chris Biemann, Ido Dagan. Proceedings of the 2015 Conference of the North American Chapter of the Association for Computational Linguistics: Human Language Technologies. 2015.

  7. A Web-based Tool for the Integrated Annotation of Semantic and Syntactic Structures

    2016 · International Conference on Computational Linguistics

    We introduce the third major release of WebAnno, a generic web-based annotation tool for distributed teams. New features in this release focus on semantic annotation tasks (e.g. semantic role labelling or event annotation) and allow …
