Automated subgroup

OpenSource

This web application provides a service for an automated subgroup fairness analysis of a binary classifier. Our system detects the subgroups in the data automatically by using either subgroups obtained from clustering the dataset or entropy-based patterns derived from the found clusters.

​Umsetzung kryptographie-basierter Verfahren zur sicheren Datenverwaltung in Cloud-Datenbanken

OpenAccess, OpenSource

Column family stores are a special case of NoSQL databases. To achieve data protection while at the same time supporting advanced data management in these stores, novel cryptographic algorithms like order-preserving and searchable encryption schemes are needed. In this project, several such schemes are implemented and tested with the stores Apache HBase and Apache Cassandra.

German Parliamentary Corpus

OpenData, OpenMethodology, OpenSource

GerParCor is a genre-specific corpus of (predominantly historical) German-language parliamentary protocols from three centuries and four countries, including state and federal level data. In addition, GerParCor contains conversions of scanned protocols and, in particular, of protocols in Fraktur converted via an OCR process based on Tesseract. All protocols were preprocessed by means of the NLP pipeline of spaCy3 and automatically annotated with metadata regarding their session date. GerParCor is made available in the XMI format of the UIMA project. In this way, GerParCor can be used as a large corpus of historical texts in the field of political communication for various tasks in NLP.

Extension of HeidelTime

OpenMethodology, OpenSource

HeidelTime is one of the most widespread and successful tools for detecting temporal expressions in texts. Since HeidelTime's pattern matching system is based on regular expression, it can be extended in a convenient way. We present such an extension for the German resources of HeidelTime: HeidelTimeext. The extension has been brought about by means of observing false negatives within real world texts and various time banks. The gain in coverage is 2.7 % or 8.5 %, depending on the admitted degree of potential overgeneralization. We describe the development of HeidelTimeext, its evaluation on text samples from various genres, and share some linguistic observations.

​SemioGraph

OpenSource

SemioGraph aims to encode as much information as possible in one and the same graph representation. This is interesting for word networks, for example, where one needs to visualize units of information such as POS, node weight, node saliency, node centrality, etc. To present SemioGraph, we use word embedding networks.

​TTLab-Embeddings

OpenData

The Text Technology Lab provides on this page a list of ready-made embeddings created by the Lab. The list contains a variety of downloadable embeddings of different methods and parameters. Metadata is available for all files, with information about the corpus, the method, the tool hyper parameters and much more. This allows a detailed search and easy recovery as well as the reuse of the embedding files. All data is also available through a RESTful API.
