Peer-to-peer computing is emerging as a new distributed computing paradigm for many novel applications that involve exchange of information among a large number of peers with little centralized coordination. Scalability is without doubt the foremost requirement for a peer-to-peer system. To obtain a high factor of scalability, we partition network search space using a global ontology. Our proposed system takes the form of a semantic layer that can be superimposed on top of any P2P

We choose HyperCup structure to support semantic category in order to increase fault tolerance and overcome bottleneck problem. HyperCup was also selected, because of its efficient broadcast algorithm. Classification within a semantic category will be conducted through multidimensional data analysis. The classification process will be recursively repeated with ontology refinement. We use digital libraries to illustrate our system, and highlight the proposed techniques.
