In recent years, scientists at the Austrian Institute of Technology have been involved in numerous projects in the digital humanities area. In this talk, Dr. Bernhard Haslhofer will present two of them, both having a strong focus on applying the Linked Open Data method on datasets produced throughout the project. The first is Maphub (http://maphub.github.io/), an open source Web application which allows users to create annotations on historical maps, link these annotations with other Web sources (e.g., Wikipedia), and share annotations as Linked Open Data following the Open Annotation model. The second is Pelagios (http://pelagios-project.blogspot.co.at/), a community initiative that aims to facilitate better linking between online resources documenting the past, based on the places they refer to. To date, Pelagios interconnects 900.000+ heterogeneous digital objects - literature, archaeology, epigraphy, cartography - from 40+ international partners. The current focus of the project is to annotate Early Geospatial Documents - documents that use written or visual representation to describe geographic space prior to the European discovery of the Americas in 1492, and make the annotations available as (Linked) Open Data.
