I still have Time(s): Extending HeidelTime for German Texts (2022.lrec-1)
Copied to clipboard
| Challenge: | HeidelTime is a widely used tool for detecting temporal expressions in texts. |
| Approach: | They propose to extend HeidelTime's pattern matching system by observing false negatives within real world texts and various time banks. |
| Outcome: | The proposed extension can detect expressions in texts and time banks in a convenient way. |
German Parliamentary Corpus (GerParCor) (2022.lrec-1)
Copied to clipboard
| Challenge: | German parliaments have a large and partly unexploited treasure trove of publicly accessible texts. |
| Approach: | a new corpus of German-language parliamentary protocols is made available in XMI format . the corpus is genre-specific and contains conversions of scanned protocols . a researcher at the university of berlin and a professor at the berlin university created the corpuus . |
| Outcome: | the German Parliamentary Corpus is a genre-specific corpus of German-language parliamentary protocols from three centuries and four countries. |
German Parliamentary Corpus (GerParCor) Reloaded (2024.lrec-main)
Copied to clipboard
| Challenge: | In 2022, the largest German-speaking corpus of parliamentary protocols from three different centuries has been published - GerParCor. |
| Approach: | They propose to update the largest German-speaking corpus of parliamentary protocols from three different centuries, on a national and federal level, from Germany, Austria, Switzerland and Liechtenstein, and to make them available in XMI format. |
| Outcome: | The updated corpus includes all new parliamentary protocols and adds and preprocesses further parliamentary protocol not covered in the previous version. |
A UIMA Database Interface for Managing NLP-related Text Annotations (L18-1)
Copied to clipboard
| Challenge: | despite the use of UIMA as a document-based schema, it does not provide native database support. |
| Approach: | They develop a database interface to allow generic use of UIMA documents in database systems. |
| Outcome: | The framework is evaluated in relation to file system-based storage and provides data protection. |
TextAnnotator: A UIMA Based Tool for the Simultaneous and Collaborative Annotation of Texts (2020.lrec-1)
Copied to clipboard
| Challenge: | Existing annotation tools are not efficient for the annotation of corpora and are not error-free. |
| Approach: | They propose to extend existing annotation tools by evaluating their flexibility and efficiency. |
| Outcome: | The proposed system performs platform-independent multimodal annotations and annotates complex textual structures. |
Unlocking the Heterogeneous Landscape of Big Data NLP with DUUI (2023.findings-emnlp)
Copied to clipboard
| Challenge: | Automated analysis of large corpora is a complex task, especially in terms of time efficiency. |
| Approach: | They propose a framework for automatic distributed analysis of text corpora that leverages Big Data experience and virtualization with Docker. |
| Outcome: | The proposed framework is scalable, flexible, lightweight, and feature-rich for automatic distributed analysis of text corpora. |

Andy Luecking, Giuseppe Abrami, Leon Hammerla, Marc Rahn, Daniel Baumartz, Steffen Eger, Alexander Mehler
| Challenge: | Using the examples of English and German, we examine how parsers trained on modern variants of these languages can be transferred to older language levels without loss. |
| Approach: | They develop a treebank of diachronic corpora enriched with dependency annotations using 3 parsers, 6 pre-trained language models, 5 newly trained models for German, and two tag sets. |
| Outcome: | The proposed treebank covers the time period from 1800 until today and is based on the DependencyAnnotator annotation tool. |
TreeAnnotator: Versatile Visual Annotation of Hierarchical Text Relations (L18-1)
Copied to clipboard
| Challenge: | TREEANNOTATOR is a browser-based tool for annotating tree-like structures . it provides a wider range of formats and provides graphical annotations . |
| Approach: | They evaluate TREEANNOTATOR, a browser-based tool for annotating tree-like structures, in particular structures that jointly map dependency relations and inclusion hierarchies, as used by Rhetorical Structure Theory. |
| Outcome: | The GUI interface is user-friendly and provides two visualization modes. |
