Task-Specific Embeddings for Ante-Hoc Explainable Text Classification

no code implementations30 Nov 2022 Kishaloy Halder, Josip Krapac, Alan Akbik, Anthony Brew, Matti Lyra

In a series of experiments, we show that this yields a number of interesting benefits: (1) The resulting order induced by distances in the embedding space can be used to directly explain classification decisions.

Early Detection of Sexual Predators in Chats

1 code implementation ACL 2021 Matthias Vogt, Ulf Leser, Alan Akbik

We define and study the task of early sexual predator detection (eSPD) in chats, where the goal is to analyze a running chat from its beginning and predict grooming attempts as early and as accurately as possible.

Task-Aware Representation of Sentences for Generic Text Classification

1 code implementation COLING 2020 Kishaloy Halder, Alan Akbik, Josip Krapac, Roland Vollgraf

FLERT: Document-Level Features for Named Entity Recognition

1 code implementation13 Nov 2020 Stefan Schweter, Alan Akbik

Current state-of-the-art approaches for named entity recognition (NER) typically consider text at the sentence-level and thus do not model information that crosses sentence boundaries.

K-SRL: Instance-based Learning for Semantic Role Labeling

no code implementations COLING 2016 Alan Akbik, Yunyao Li

To overcome this challenge, we propose the use of instance-based learning that performs no explicit generalization, but rather extrapolates predictions from the most similar instances in the training data.
