In this paper, we propose and develop a platform to support data collection for mobile crowdsensing from mobile device sensors that is under-pinned by real-time mobile data stream mining. We experimentally show that mobile data mining provides an efficient and scalable approach for data collection for mobile crowdsensing. Our approach results in reducing the amount of data sent, as well as the energy...
We propose a trust model for social networks with the aim of building trust communities that inspire members to share their experiences, feelings and opinions in an open and honest way without the fear of being judged. The unique feature of our model is that the trust value is derived from the social capital built in the social networks over a period of time. First, we introduce a framework for building...
We propose a trust prediction model for service Web using the Hidden Markov Model (HMM). The proposed model uses a dynamic training scheme that incorporates temporal sensitivity by using a dynamic training pool. The concept of the dynamically updated training pool enables the system to absorb newest information from data. We present the implementation of the proposed model and corresponding algorithm...
We propose a novel semantic service trust organization that uses an ontological approach to model service trust. In particular, our ontology-based organization supports various trust phases including trust bootstrapping, atomic service trust, trust composition and trust propagation. We describe the implementation of the proposed trust organization.
We propose a fuzzy trust management framework for the Service Web. The proposed framework supports a natural way of representing and querying consumers' perception on services. We describe the underlying models, algorithms and an implementation architecture, mainly focusing on the key features and contributions of the proposed framework.
A collection of 1 billion1 publicly available web services can form an internet-scale infrastructure for building diverse applications. For a given application, selection of services and service providers from this collection becomes important and reputation is recognized as a key factor for this purpose. However, current reputation systems are limited in their ability to exchange reputation information...
