Clustering algorithm

which algorithm in neo4j i can use to group similar nodes in a cluster? Please i need help

There are many. Here is the entry point to the documentation. You should have a look at "similarity" and "community detection" algorithms and see what suits your use case, and then ask more specific questions if you need further help, in a different thread.
