Abstract:
A social network represents a social community as a directed graph. Communication on the Web has given rise to social network formation like, Web Community, Referral System etc. An earlier effort has proposed a data model for such Web-based social network. Present paper discusses the relevant index structures for processing queries on a social network schema based upon the proposed data model. The paper has also provided evaluation of the structural operators proposed in the data model and discussed their efficacy with query examples.
