Abstract
The distributed nature of our digital healthcare and the rapid emergence
of new data sources prevents a compelling overview and the joint use of new data.
Data integration, e.g., with metadata and semantic annotations, is expected to
overcome this challenge. In this paper, we present an approach to predict UMLS
codes to given German metadata using recurrent neural networks. The augmentation
of the training dataset using the Medical Subject Headings (MeSH), particularly the
German translations, also improved the model accuracy. The model demonstrates
robust performance with 75% accuracy and aims to show that increasingly
sophisticated machine learning tools can already play a significant role in data
integration.
