Confidence-Aware Reputation Bootstrapping in Composite Service Environments

Reputation Bootstrapping for Composite Services using CP-nets

“…In contrast, the reputation of a composite service depends on the aggregated reputation of its component services [13]. Linear aggregation models are proposed for bootstrapping composite services without considering the dynamic performance of component services in different contexts [2], [8], [13]. However, aggregating reputation-related factors of component services is not straight-forward due to the service topology and reputation interdependence among component services.…”

“…The reputation interdependence varies in different layers of the reputation-related factors. For example, a component service usually has multiple reputation-related factors (e.g., its provider, the community, and similar services) [8]. We use Conditional Preference Networks (CP-nets) [14] to model the relative importance among reputation-related factors.…”

“…• Characteristic-based approaches: This category focuses on reputation-related factors [8] and uses inheritance and referral mechanisms to bootstrap reputation of a new service [9]. A trust framework is proposed in [19] that considers community context factors for establishing trust in the peer-to-peer electronic communities.…”

“…Reputation bootstrapping is an efficient process that performs an indirect assessment of reputation when users' feedback is not available [2], [8]. Various reputation-related factors such as the reputation of the service provider, community or interrelated services are used for the indirect assessment.…”

“…Various reputation-related factors such as the reputation of the service provider, community or interrelated services are used for the indirect assessment. The reputation of the service provider is used to predict the future performance of a new service [8], [9]. Another approach [10] assumes that the reputation of a new service may follow the reputation trend of functionally similar services.…”
