Monuments Digital Library

Given the chance, every man, woman and child would like to visit at least one of the Seven Wonders of the World. However, over 99% of us never get the opportunity to see any of them. Advances in information and communication technologies make it possible for us to experience the pleasure of visiting these locations without physically going there. The DOI is proposing a multi-national effort to begin to create the content and make it accessible around the world so that anyone who wishes to visit one of these sites virtually can do so with the click of a mouse from the comfort of their home or office. While the necessary research has been done, 3D modeling of each of these locations can be expensive and time consuming. 

Spoken Language Digital Library

The DOI is a center for innovations in speech and language to collect and annotate the recorded speech. This initiative is designed to support research into innovative methodologies in knowledge representation and knowledge acquisition applied to speech recognition and synthesis. This very ambitious data collection effort comprising at least a million hours of recorded speech in at least 100 languages will be accomplished by utilizing DOI centers all over the globe as speech collection centers. This Million-Hour Corpus will be the basis for a major international research program aimed at dramatically improving the performance of speech recognition and speech synthesis systems, as well as making these technologies available is many more languages.
