Magnus Pfeffer

Prof. Magnus Pfeffer is a faculty member at Hochschule der Medien Stuttgart, affiliated with the Faculty of Information and Communication and the Department of Information Science. He holds the academic rank of Professor and is actively engaged in research and teaching in information science, digital libraries, and semantic technologies.

His research interests include:

• Semantic Web and Knowledge Graphs
• Metadata Management and Interoperability
• Knowledge Organization and Classification Systems
• Information Retrieval in Heterogeneous Environments
• Digital Humanities, particularly Japanese Visual Media (Anime, Manga, Otaku Culture)
• Integration of Fan-Created and Community Data

His recent publications (2022–2018) reveal a strong focus on the Japanese Visual Media Graph project, which builds domain-specific knowledge graphs by integrating data from enthusiast communities using RDF, ontologies, and semantic web standards. This work bridges library science with digital humanities and addresses challenges in licensing, data harmonization, and research utility of crowdsourced metadata. Earlier works focus on automated indexing, classification system mapping, and metadata enrichment in library contexts.

Scientific contributions include:

• Development of ontologies for anime characters, visual novels, and fan databases
• Legal and technical integration of open-licensed community databases
• Innovations in retro-classification and metadata provenance
• Curriculum development in information science, especially IT competencies and pandemic-era teaching
