Inferential rules are essential to the semantic web application as ontology. The ontology techniques can be used for extract creative information but it has some issues.

In our proposed approach Best First Search (BFS) and Constraint Directed Search (CDS) algorithm used to demonstrate the outcome graphically and to appraise performance metrics.
