Implementation of regular expression (regex) on knowledge management system

Hitherto, previous research of string matching techniques in knowledge sharing of explicit knowledge have shown a great success. However, their implementation in a knowledge management system is still underexplored. The aim of this paper is to propose an implementation of regular expression (regex) techniques for supporting all processes in knowledge management systems and producing a better accuracy of searching knowledge within an organization. A web-based application prototype of regex is built and several experiments are performed in order to prove the correctness of our implementation. It is obvious that regex performs better than traditional SQL concerning with knowledge searching/query.
