The prevalence of video content consumption prompted book publishers to adopt this medium as a way to advertise books, through so called book trailers. Beyond advertising, a book’s video presentation may provide information to potential future readers so they can make an informed choice on whether consider reading it or not. StoryBook is a software tool that, through a process of knowledge extraction and media collection, supports the semi-automatic creation of multimedia trailers of books. A proof-of-concept of the tool and its user interface has been built and is available online.

In this demo paper, we present ARCA, a visual-search based system that allows the semantic exploration of a bookstore. Navigating a domain-specific knowledge graph, students and researchers alike can start from any specific concept and reach any other related concept, discovering associated books and information. To achieve this paradigm of interaction we built a prototype system, flexible and adaptable to multiple contexts of use, that extracts semantic information from the contents of a books' corpus, building a dedicated knowledge graph that is linked to external knowledge bases.
