Flexible and scalable digital library search
No full textThe everlasting search for new methods to explore the Inter- or Intranet is still going on. In this demo we present the combined effort of the AMIS and DMW research projects, each covering significant parts of this problem.
The contribution of this demo is twofold. Firstly, we demonstrate how feature grammars offer a flexible solution for extraction and querying of meta-data from multimedia documents in general. Scalability and efficiency support are illustrated for full text indexing and retrieval. Secondly, we show how for a more limited domain, like an Intranet, conceptual modeling can offer additional and more powerful query facilities. The limited domain case, also allows the extraction and querying of high-level concepts from raw video data
Identifying Internet-related database research
No full textWith the arrival of the Information Society, which is getting great political support, computer science has to wonder whether the research efforts are focused on the right topics. Activities such as World-Wide Web are leading us the way to the “Information Superhighway”. As a database community we have to ask ourselves what can we contribute to this field. By discussing various issues of finding relevant data on the Internet, Internet-related database research topics are identified
