Description Knowledge Graphs (KGs) have emerged as a core technology for incorporating human knowledge because of their capability to capture the relational dimension of information and of its semantic properties. The nature of KGs meets one of the vocational pursuits of academic institutions, which are sharing their intellectual output, especially publications.

In this thesis we propose to continue the development of Geranium (https://www.mdpi.com/2078-2489/12/9/366), a Knowledge Graph (KG) and Graph Neural Networks (GNNs) based search, discovery and recommendation engine for academic publications built by the Nexa Center for Internet and Society.

The thesis will involve the development of new features for the platform, the expansion of the knowledge base and the application of Geranium to new domains, other than the one already explored (i.e. academic publications).
