Is that really a question? Going beyond factoid questions in NLP

1 code implementation IWCS (ACL) 2021 Aikaterini-Lida Kalouli, Rebecca Kehlbeck, Rita Sevastjanova, Oliver Deussen, Daniel Keim, Miriam Butt

Research in NLP has mainly focused on factoid questions, with the goal of finding quick and reliable ways of matching a query to an answer.

SyntaxShap: Syntax-aware Explainability Method for Text Generation

no code implementations14 Feb 2024 Kenza Amara, Rita Sevastjanova, Mennatallah El-Assady

We adopt a model-based evaluation to compare SyntaxShap and its weighted form to state-of-the-art explainability methods adapted to text generation tasks, using diverse metrics including faithfulness, complexity, coherency, and semantic alignment of the explanations to the model.

Negation, Coordination, and Quantifiers in Contextualized Language Models

no code implementations COLING 2022 Aikaterini-Lida Kalouli, Rita Sevastjanova, Christin Beck, Maribel Romero

With the success of contextualized language models, much research explores what these models really learn and in which cases they still fail.

Explaining Contextualization in Language Models using Visual Analytics

no code implementations ACL 2021 Rita Sevastjanova, Aikaterini-Lida Kalouli, Christin Beck, Hanna Sch{\"a}fer, Mennatallah El-Assady

Despite the success of contextualized language models on various NLP tasks, it is still unclear what these models really learn.

XplaiNLI: Explainable Natural Language Inference through Visual Analytics

no code implementations COLING 2020 Aikaterini-Lida Kalouli, Rita Sevastjanova, Valeria de Paiva, Richard Crouch, Mennatallah El-Assady

Advances in Natural Language Inference (NLI) have helped us understand what state-of-the-art models really learn and what their generalization power is.

ParHistVis: Visualization of Parallel Multilingual Historical Data

no code implementations WS 2019 Aikaterini-Lida Kalouli, Rebecca Kehlbeck, Rita Sevastjanova, Katharina Kaiser, Georg A. Kaiser, Miriam Butt

The study of language change through parallel corpora can be advantageous for the analysis of complex interactions between time, text domain and language.

VIANA: Visual Interactive Annotation of Argumentation

no code implementations29 Jul 2019 Fabian Sperrle, Rita Sevastjanova, Rebecca Kehlbeck, Mennatallah El-Assady

The results show that experts prefer our system over existing solutions due to the speedup provided by the automatic suggestions and the tight integration between text and graph views.
