Natural Language Processing GroupWelcome to the Natural Language Processing Group at the Computational Linguistics Department at Heidelberg University!
Our research focuses on Advanced Semantic Analysis and Discourse Processing Models for Natural Language Understanding.
Recent research themes and applications
- Question Answering and Reading Comprehension
- Discourse Relation Classification
- Deep Sentiment Analysis
- Multilingual Semantic Role Labeling
- Abstract Anaphora Resolution
- Knowledge-based Argumentation Analysis

- We're happy to announce that the paper Reconstructing Implicit Knowledge with Language Models by Maria Becker, Siting Liang and Anette Frank has earned the Best Paper Award at DeeLIO: The 2nd Workshop on Knowledge Extraction and Integration for Deep Learning Architectures at NAACL 2021. With this we conclude our work in ExpLAIN in the SSP RATIO project.
- We are delighted to announce eight papers on interpretation and reasoning in NLU and NLG using Commonsense Knowledge, on Multilingual AMR Parsing, and on Multimodal Image and Language processsing. All details can be found here. Congratulations to all authors!
- The NLP Group will welcome new team members in 2021: Philipp
Wiesenbach will join the ACCEPT project, to work on Computational
Argumention, and Xiyan Fu will join us to research new topics in
Natural Language Understanding and Generation. We are looking
forward to the new team members joining the group in May and July!
- There will be three dissertation defenses in the upcoming
months: Angel Daza and Maria Becker
will defend their theses in May, and
Mihaylov will defend his thesis in June/July! Angel and Todor
have already started their new positions at the University of
Amsterdam and at Facebook AI in Menlo Park, and Maria will soon start her
new position at the Department of German Studies at Heidelberg University.
Frank will be Action Editor for TACL starting July 2021.
- Maria Becker and Katharina Korfhage will present CoCo-Ex in the EACL
Track. CoCo-Ex: A Tool For Linking Concepts From Texts To ConceptNet allows users to ground ConceptNet concepts in
textual sequences. Find paper, code and video at EACL 2021.
- We are happy to announce a new paper accepted for EACL 2021: Towards a Decomposable Metric for Explainable Evaluation of Text Generation from AMR, by Juri Opitz and Anette Frank. Pre-print available from arXiv. Congratulations to the authors!
- We have two openings for PhD candidates:
- A doctoral scholarship in Natural Language Understanding and Generation
- A PhD position in our new DFG project ACCEPT in the priority program RATIO (Robust Argumentation Machines)
- We have a new project accepted in the 2nd phase of the
Priority Program RATIO: Robust Argumentation Machines. The project
ACCEPT: Perspectivized Argument Knowledge Graphs for Deliberation
Support will be jointly conducted by Prof. Anette Frank and Prof. Philipp Cimiano (University Bielefeld).
- Two members of the HD NLP group have been rewarded for
outstanding contributions to EMNLP 2020: Anette Frank as
outstanding Area Chair and Juri Opitz as outstanding
Reviewer. Congrats. We appreciate such recognitions for
- Two new blog posts in our HD NLP blog (very interesting to read!):
- Two long papers by members of the NLP group have been
accepted for EMNLP
Congratulations to the authors!
- X-SRL: A Parallel Cross-Lingual Semantic Role Labeling Dataset, by Angel Daza and Anette Frank, to appear in the Proceedings of EMNLP. The publication is based on work within the LiMo project

- The paper Argumentative Relation Classification with Background Knowledge, by Debjit Paul, Juri Opitz, Maria Becker, Jonathan Kobbe, Graeme Hirst, and Anette Frank earned a nomination for the best student paper award at the COMMA 2020 Conference! Congratulations to all authors!
- Three new publications by members of the NLP group and colleagues:
- Juri Opitz, Letitia Parcalabescu and Anette Frank (2020): AMR Similarity Metrics from Principles. Transactions of the Association for Computational Linguistics, Vol. 8, pp. 522-538. [html]

- In the newest issue of Heidelberg University's research
magazine on â€śMachine
& Humanâ€ť, Anette Frank and Katja Markert
Challenges of Teaching Machines to Understand Human Language".
They discuss current work of their research groups and argue that both commonsense knowledge and creativity -
which humans master so easily - are still a challenge for automatic
language processing algorithms. Enjoy!
- New publication: Letitia Parcalabescu and Anette Frank: Exploring Phrase Grounding without Training: Contextualisation and Extension to Text-Based Image Retrieval. Workshop on Multimodal Learning (at CVPR 2020), [pdf].
- Anette Frank will be Area Chair in the Semantics track" for EMNLP 2020.
- Anette Frank will be Area Chair in the Semantics Track for ACL 2020 in Seattle.
Frank and Letitia Parcalabescu are
participating in the newly established COST Action
Multi3Generation: Multi-task, Multilingual, Multi-modal Language
Generation, led by Isabelle Augenstein.
We are members of the management committee as representatives for
We are looking forward to collaborating in this great network activity.
