Investigating the Robustness of Modelling Decisions for Few-Shot Cross-Topic Stance Detection: A Preregistered Study

1 code implementation5 Apr 2024 Myrthe Reuver, Suzan Verberne, Antske Fokkens

In this paper, we investigate the robustness of operationalization choices for few-shot stance detection, with special attention to modelling stance across different topics.

The Role of Syntactic Span Preferences in Post-Hoc Explanation Disagreement

1 code implementation28 Mar 2024 Jonathan Kamp, Lisa Beinborn, Antske Fokkens

We systematically investigate the interaction between $k$ and spans and propose an improved configuration for selecting important tokens.

Dynamic Top-k Estimation Consolidates Disagreement between Feature Attribution Methods

no code implementations9 Oct 2023 Jonathan Kamp, Lisa Beinborn, Antske Fokkens

Feature attribution scores are used for explaining the prediction of a text classifier to users by highlighting a k number of tokens.


Better Hit the Nail on the Head than Beat around the Bush: Removing Protected Attributes with a Single Projection

no code implementations8 Dec 2022 Pantea Haghighatkhah, Antske Fokkens, Pia Sommerauer, Bettina Speckmann, Kevin Verbeek

Applying one targeted (MP) projection hence is methodologically cleaner than applying multiple (INLP) projections that introduce random effects.

Dealing with Abbreviations in the Slovenian Biographical Lexicon

1 code implementation4 Nov 2022 Angel Daza, Antske Fokkens, Tomaž Erjavec

We also propose and present the results of a method for expanding the identified abbreviations in context.

Perturbations and Subpopulations for Testing Robustness in Token-Based Argument Unit Recognition

1 code implementation ArgMining (ACL) 2022 Jonathan Kamp, Lisa Beinborn, Antske Fokkens

Argument Unit Recognition and Classification aims at identifying argument units from text and classifying them as pro or against.


Hate Speech Criteria: A Modular Approach to Task-Specific Hate Speech Definitions

no code implementations NAACL (WOAH) 2022 Urja Khurana, Ivar Vermeulen, Eric Nalisnick, Marloes van Noorloos, Antske Fokkens

We argue that the goal and exact task developers have in mind should determine how the scope of \textit{hate speech} is defined.

Is Stance Detection Topic-Independent and Cross-topic Generalizable? -- A Reproduction Study

no code implementations14 Oct 2021 Myrthe Reuver, Suzan Verberne, Roser Morante, Antske Fokkens

Cross-topic stance detection is the task to automatically detect stances (pro, against, or neutral) on unseen topics.

Challenging distributional models with a conceptual network of philosophical terms

1 code implementation NAACL 2021 Yvette Oortwijn, Jelke Bloem, Pia Sommerauer, Francois Meyer, Wei Zhou, Antske Fokkens

We investigate the possibilities and limitations of using distributional semantic models for analyzing philosophical data by means of a realistic use-case.


Would you describe a leopard as yellow? Evaluating crowd-annotations with justified and informative disagreement

no code implementations COLING 2020 Pia Sommerauer, Antske Fokkens, Piek Vossen

We establish an additional, agreement-independent quality metric based on answer-coherence and evaluate it in comparison to existing metrics.

Large-scale Cross-lingual Language Resources for Referencing and Framing

no code implementations LREC 2020 Piek Vossen, Filip Ilievski, Marten Postma, Antske Fokkens, Gosse Minnema, Levi Remijnse

In this article, we lay out the basic ideas and principles of the project Framing Situations in the Dutch Language.

Combining Conceptual and Referential Annotation to Study Variation in Framing

no code implementations LREC 2020 Marten Postma, Levi Remijnse, Filip Ilievski, Antske Fokkens, Sam Titarsolej, Piek Vossen

The user can apply two types of annotations: 1) mappings from expressions to frames and frame elements, 2) reference relations from mentions to events and participants of the structured data.

Conceptual Change and Distributional Semantic Models: an Exploratory Study on Pitfalls and Possibilities

no code implementations WS 2019 Pia Sommerauer, Antske Fokkens

Studying conceptual change using embedding models has become increasingly popular in the Digital Humanities community while critical observations about them have received less attention.

Firearms and Tigers are Dangerous, Kitchen Knives and Zebras are Not: Testing whether Word Embeddings Can Tell

no code implementations WS 2018 Pia Sommerauer, Antske Fokkens

The idea behind this method is that properties identified by classifiers, but not through full vector comparison are captured by embeddings.
