The role of the SGC-SGI is to inform state and public sector agencies on important events, as well as views and reactions of Greek and foreign public opinion, including the mass media, on issues affecting the country. SGC-SGI collects data in the field of national, political, social, economic, cultural, and environmental issues concerning Greece, as well as international issues that are relevant to the country and/or the international bodies of which Greece is a member. Journalists, analysts, and political scientists then process the news sources to assess national and international news, photos, as well as radio and television material. As part of a larger electronic government (e-Government) initiative, SGC-SCI works with mass-media authorities, universities, and private companies, within a unified framework for information access, to provide innovative electronic services (e-services) for both the government and the public. QualiArc is the integrated environment that we have developed for accessing and annotating multimedia digital content, providing advanced searching and browsing capabilities. We have successfully applied emerging technologies for data storage, indexing and retrieval, and we have integrated them into a large video and audio library system that covers broadcast news and current affairs in Greek and English. The SGC-SGI digital video archive uses intelligent automatic mechanisms that provide full-content search and retrieval from a large online digital video library. Τhe tools that we developed during the project automatically populate the library and support access to it. The approach that we have followed uses speech recognition in Greek and English and language processing technologies to automatically transcribe, segment and index the video. Retrieval is text-based, performed on the material that results from speech recognition or on the metadata manually created by the user.
