An innovative system for formulating complex, combined content-based and keyword-based queries

摘要

We propose a search & retrieval (S&R) tool, which supports the combination of a text search with content-based search for video and image content. This S&R system allows the formulation of complex queries allowing the arbitrary combination of content-based and text-based query elements with logical operators. The system will be implemented as a client/server system. The entire S&R system is designed in such a way that the client system can be either a web application accessing the server over the Internet or a native client with local access to the server. The S&R tool is embedded into a system called "MECiTV - Media Collaboration for iTV". Within MECiTV a complete authoring environment for iTV content will be developed. The proposed S&R tool will enable iTV authors and content producers to efficiently search for already existing material in order to reduce costs for iTV productions.
