The Linked Open Data Portal (LODPortal) is an open source application for the Digital Humanities which has been developed within the European Project (CIP-ICT-PSP) Agora -- Scholarly Open Access Research in European Philosophy. Although it is in aprototypal stage of development, it presents an innovative use of Linked data technologies applied to the Digital Humanities domain. By combining thousands of resources coming from different Digital Libraries, thanks to the use of Semantic Web technologies it offers to Scholars novel tools to create, reuse and visualize research data and results. In particular, the LODPortal gathers and indexes resources coming from twelve Digital Libraries and the Linked Data cloud (such as DBPedia and Freebase) and includes a module based on Pundit, enabling automatic entity extraction, thanks to the service DANDELION, and manual semantic enrichment. Based on the semantic indexing, the navigation interface offers advanced visualizations such as the Timeline, the people graph and a map of places.
