Visual exploration of digital cultural artifacts

We exploited the synergy between semantic technologies and knowledge exploration tools for digital libraries, proposing a system which includes: semantic enrichment of textual content; a user interface for search and exploration of a digital library through visual navigation of a knowledge graph of topics; the extensions of the central system to leverage the extracted knowledge. For example, interface components hide complex queries to find interesting topics for users; an integrated system to semi-automatically manage the knowledge contained in the images, generating video trailers of books; and a collaborative system to improve extracted data quality.
