Development of Web 2.0 enabled users to share information online, which results into an exponential growth of world wide web data. This leads to the so-called information overload problem. Recommender Systems (RS) are intelligent systems, helping on-line users to overcome information overload by providing customized recommendations on various items. In real world, people are willing to take adv...

Peer-to-Peer (P2P) is a self-organizing resource sharing network with no centralized authority or infrastructure, which makes it unpredictable and vulnerable. In this paper, we propose architecture to make the peer-to-peer network more centralized, predictable, and safer to use by implementing trust and stopping free riding. Keywords— File Share, Free Riding, Peer-to-Peer, Trust.

A hierarchical framework is proposed to address the issues of modeling different type of words in keyword spotting (KWS). Keyword models are built at various levels according to the availability of training set resources for each individual word. The proposed approach improves the performance of KWS even when no training speech is available for the keywords. It also suggests an easier way to co...

With the increase in an online transactions and interactions on the internet, a key issue is how to use efficient and simple evaluation method to achieve trust based decisionmaking for service users and service providers. Trust plays an important role in all commercial cloud environments. It is the evaluation of capability of service providers as well as service users in completing a task based...

Previous research on reputation systems has primarily focused on the trust building function of reputation systems. The current research also addresses the trust rebuilding function of reputation systems, specifically, the role of the short text comments given in reaction to negative feedback. Online markets are noisy environments; rebuilding trust is therefore often necessary. The results of t...

Trust management is one of the drawbacks in Peer-toPeer (P2P) system. Lack of centralized control makes it difficult to control the behavior of the peers. Reputation system is one approach to provide trust assessment in P2P system. In this paper, we use fuzzy logic to model trust in a P2P environment. Our trust model combines first-hand (direct experience) and second-hand (reputation) informati...

The major challenge faced by wireless sensor networks is security. Because of dynamic and collaborative nature of sensor networks the connected sensor devices makes the network unusable. To solve this issue, a trust model is required to find malicious, selfish and compromised insiders by evaluating trust worthiness sensors from the network. It supports the decision making processes in wireless ...
