A Vague Words Retrieval Method in a Relational Database
Rui Wang, Ping Dao Gu, Jian Min Zeng · Applied Mechanics and Materials · 2012
In this paper, we propose a vague words retrieval method over text field of relational databases. This method is expected to get an ideal retrieval result from text field of relational databases when a set of incorrect keywords is submitted. The solution to this issue is: to create a “hot words library”, then let the input incorrect keywords match with the word of “hot words library”, based on the modified dynamic programming algorithm of k-difference approximate string matching. Finally, Experiments show that this solution has a good query performance.
