This thesis explores the critical role of effective knowledge management in non-profit organisations, particularly those involved in child rights advocacy in Switzerland. It identifies the pervasive issue of information silos within these NGOs, which impede internal communication and external collaboration, thereby limiting their capacity to advocate effectively. Contributing factors include fragmented data storage, limited accessibility, and organisational cultures discouraging knowledge sharing. The research posits that Knowledge Graphs (KGs) present a viable solution to these fragmentation issues by enabling sophisticated data integration and analysis across diverse sources.
