Content-Based Query Processing for Video Databases
This paper presents a query processing strategy for the content-based video query language named CVQL. By CVQL, users can flexibly specify query predicates by the spatial and temporal relationships of the content objects. The query processing strategy evaluates the predicates and returns qualified videos or frames as results. Before the evaluation of the predicates, a preprocessing is performed...
متن کاملQuery Rewriting for Rule Mining in Databases
Promoting declarative approaches in data mining is a long standing theme. This paper goes into this direction by proposing a wellfounded logical query language, SafeRL, allowing the expression of a wide variety of “rules” to be discovered against the data. SafeRL extends and generalizes functional dependencies in databases to new and unexpected rules easily expressed with a SQL-like language. I...
متن کاملA Content-Based Query Language for Video Databases
This paper presents a content-based video query language CVQL for video databases. Spatial and temporal relationships of content objects are used for the specification of query predicates. Queries of realism are illustrated to show the power of CVQL. Macro definitions are supported to simplify query specification. Index structures and query processing for CVQL are considered, and a prototype vi...
متن کاملThe fuzzy logic based ECA rule processing for XML databases
Current needs of E-Commerce transactions require the development of XML database system like relational database systems. Fuzzy concepts are adapted to the field of XML Databases (DB) in order to deal with ambiguous and uncertain data. Incorporating fuzziness into Event Condition Action (ECA) rules would improve the effectiveness of XML DB as it provides much flexibility in defining rules for t...
متن کاملTechnical Report: Parallel Distance Threshold Query Processing for Spatiotemporal Trajectory Databases on the GPU
Processing moving object trajectories arises in many application domains and has been addressed by practitioners in the spatiotemporal database and Geographical Information System communities. In this work, we focus on a trajectory similarity search, the distance threshold query, which finds all trajectories within a given distance d of a search trajectory over a time interval. We demonstrate t...
