Additional Information:

The research department at the TIB is relatively young and offers many opportunities. It is our vision to rethink the representation and provision of data and information and to organize them in an Open Research Knowledge Graph (ORKG) in the future. There is close cooperation with the L3S Research Centre at Leibniz University Hannover, one of the world\’s leading research institutes in the field of Web & Data Science, within the Leibniz Joint Lab Data Science & Open Knowledge.

With the Open Science Lab, TIB supports the digital opening of science by helping communities to adopt new methods and tools in their practice. Research and development activities in the OSL are closely interlinked with the training of young scientists in the Information Management degree programme at Faculty III – Media, Information and Design at Hannover University of Applied Sciences and Arts, with which TIB has established the Leibniz Joint Lab Future Libraries & Research Data.

Last but not least, we attach great importance to an open and creative working atmosphere in which it is fun to work.
