摘要: |
为了实现对UMQL的有效处理,提出了通用多媒体查询代数MQA。通过常规选择、结构选择和时空选择等代数运算来处理UMQL中的结构表达式、特征表示式和时空表达式,很好地保持了与UMQL查询描述能力的一致性,能有效地处理UMQL。 |

Abstract: |
UMQL (unified multimedia query language), which has powerful ability to specify complicated multime-dia query requirements,can support effectively queries based on the content,structure and spatio-temporal rela-tionships of multimedia data. In order to treat with UMQL effectively and efficiently,we propose a type of multime-dia query algebra,called MQA by us. It defines structured selection and spatio-temporal selection to treat withstructure feature conditions and spatio-temporal conditions of UMQL,which makes its ability on query specificationin accordant with UMQL,thus implementing a very effective treatment on UMQL. |
