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
- Identifying Implicit Information in Discourse
- Multimodal Language Processing
- 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
- Social Commonsense Reasoning with Multi-Head Knowledge Attention, by Debjit Paul and Anette Frank, to appear in Findings at EMNLP, Association of Computational Linguistics, [reprint]
- 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]
- Debjit Paul, Juri Opitz, Maria Becker, Jonathan Kobbe, Graeme Hirst, and Anette Frank (2020): Argumentative Relation Classification with Background Knowledge. Proceedings of the 8th International Conference on Computational Models of Argument (COMMA 2020) [html]
- Maria Becker, Ioana Hulpus, Debjit Paul, Juri Opitz, Jonathan Kobbe, Heiner Stuckenschmidt and Anette Frank (2020): Explaining Arguments with Background Knowledge. Towards Knowledge-based Argumentation Analysis. Datenbank Spektrum 20:131â€“141, Special Issue: Argumentation Intelligence. [DOI]
- 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.
