Top-K-oriented hierarchical keyword-based information query system architecture over databases
Li Jin · Journal of Yanshan University · 2010
It is the irrational system architecture that leads to the problems of inefficient retrieval and unsatisfied query results (in keyword query system over relational database).In order to solve the above two problems,in this paper,a top-K-oriented hierarchical keyword-based information retrieval system architecture over databases is initiated.Such an architecture is instantiated by the evaluation formula,preparation technique of index-based candidate network and top-K query algorithm of binding real-time threshold filtration.The results verify the great feasibility of this architecture.Furthermore,the query system based on this architecture can achieve good query performance.
