基于内容的可视化多媒体查询语言的设计

设计了一个基于内容的可视化多媒体查询语言CBVMQL(Content-Based Visual Multimedia Query Language),该语言将语义表达、概念化定义、面向对象的语义表示和图像示例有机地结合起来,不仅提供了一个自然的可视化查询接口,而且也支持通过自动查询生成来精确地操纵信息.同时,它还结合多媒体的内容信息,实现了基于内容的多媒体查询.

Content-Based Visual Multimedia Query Language

At present, there are two ways to get multimedia information from multimedia database. One is applying query language to manipulate information directly,it can exactly tell computer about relative query information,but its user interface is not friendly.The other one is developing query interface,but it is lowly precise.With the development of visual programm language enviroment and the technique of content-based query,it is possible to combine both of them. Therefore,query by visual example and query by pictorial example are connected,and a content-based visual multimedia query language—CBVMQL is designed,in which semantics expression, concept definition, object-oriented expression are combined. CBVMQL not only provides a visual query interface,but supports manipulation exactly of information by automatic query.Otherwise,it implements content-based multimedia query,too.
