1. Introduction: Digital and the HumanitiesComputers, digital tools, and the Internet have fundamentally changed the way scholars work, collaborate, and publish their research, and have supported the creation, storage, analysis, and dissemination of data and information. While many areas of study within the natural, medical, and social sciences have a long tradition with these technologies, most of the humanities have been more reluctant and have found it more difficult or inappropriate to integrate computational tools that are generally built to perform quantitative analyses. In recent years, new activities and new research opportunities have emerged from the intersection between the humanities disciplines and the world of digital technologies, what we now call digital humanities, represents an indefinite and heterogeneous set of studies and practices that aims to understand their implications and the opportunities that digital technologies can provide as media, tools or objects of study in the humanities [1, 2]. What is certain is that the enormous amount of information coming from digital collections and in a more general sense from the "digital world", is offering various opportunities to rethink traditional research activities and tasks in the humanities (Moretti, Manovic... ). These new relationships between the digital and the humanities are rapidly requiring new ways of observation, exploration and interpretation and in this perspective information visualization and interfaces are becoming essential tools for exploring and making sense of the growing amount of data available. Since most of the methods and technologies adopted by digital humanities come from other disciplines...... middle of paper . .....starting from the Internet, not only to study online culture, but in a more general sense as a unique data source for analyzing society and culture (Rogers, 2009). The situation in traditional arts and humanities, especially literature and historical studies, is quite different. They usually do not create their own data but rely on documents, be they newspapers, photographs, letters, diaries, books, articles; birth, death and marriage records; documents found in churches, courts, schools and universities; or maps. Fundamentally, “any record of human experience can be a source of data for a humanities scholar” (Borgman, 2009). Cultural documents and materials are usually stored in libraries, archives, museums or other public and private agencies under a complex system of access rules. and, if already digitalised, through various online platforms built with different technologies.
