Projects

Camera-based In-Line Inspection of Machine Parts

In this project, a software was developed that inspects the surface of machine parts. Based on camera images, the software detects and evaluates surface anomalies like scratches or pores. The evaluation result determines whether machine parts are accepted or rejected.

Technologies: Python, PyPylon, OpenCV, PyTorch

Open‑Source Plugins for Metadata Management of the Verfassungsblog

The Verfassungsblog is an academic Open‑Access journal discussing topics regarding constitutional law in Germany. In this project, WordPress plugins were developed to improve the management of article metadata and allow exporting information in multiple formats, e.g., as Marc21-XML.

Technologies: PHP, WordPress, MySQL, XML, XSLT

REST Service for Document Classification in Digital Libraries

In this project, the Open‑Source software “slub_docsa” was developed. It allows the comparison of state-of-the-art machine learning methods (e.g., Artificial Neural Networks) for the purpose of automatically annotating documents with detailed class hierarchies often used by libraries (e.g., DDC). A REST service provides the trained models.

Technologies: Python, Scikit-Learn, PyTorch, Transformers

Adaptation and Maintenance of the Search Tool “BLE‑X”

BLE‑X is a web-based research tool that allows to search within the full text of research reports. Search results are visualized in groups of similar documents to support users during the research process. In this project, the Java application was updated according to new requirements.

Technologies: Java, Lucene, JavaScript, jQuery, Docker
