A Large Scale Synthetic Social Provenance Database
Provenance about data derivations in social networks is commonly referred as social provenance, which helps in estimating data quality, tracking of resources, and understanding the ways of information diffusion in social networks. We observed several challenges related to provenance in the social network domain. First, provenance collection systems capture provenance on the fly; however, their collection mechanism may be faulty and have dropped provenance notifications. Hence, social provenance records may be partial, partitioned, or simply inaccurate. Although current provenance systems deliver a source of real provenance data, these systems do not provide a controlled provenance generation environment; and there are few that contain provenance with failures. Synthetic provenance databases are available in other domains, such as e-Science; but there is also a need for such a database in the social networking domain. To address these challenges, this study introduces a large-scale noisy synthetic social provenance database, which includes a high volume of large-size social provenance graphs. It also introduces metrics that can be used to capture such vital information as provenance for calculating data quality and user credibility.
