Mining big data has become an important problem in the graph pattern mining research area. Inorder to
select useful features, recent graph mining techniques applies repeated mining of frequent subgraphs either
by varying minimum supports or by dividing a graph database recursively. Frequent subgraph mining is an
import task for exploratory data analysis on graph database. Frequent subgraph mining entails two
significant overheads. It is concerted with candidate set generation and isomorphism checking. Finding
subgraph isomorphism is an important problem in many applications which deal with data modeled
asgraphs. In this work, we propose to reduced the search space and address isomorphism overheads, a
weighted approach to subgraph mining. The objective of this work is to investigate the benefits that the
concept of weighted frequent subgraph mining can offer in the context of the graph model based
classification. Weighted subgraphs are graps where some of the vertexes or edges are considered to be
more significant than others.
