Rating systems are used by many websites, which allow customers to rate available items according to their own experience. Subsequently, reputation models are used to aggregate available ratings in order to generate reputation scores for items. A problem with current reputation models is that they provide solutions to enhance accuracy of sparse datasets not thinking of their models performance ...

Online brand reputation is of increasing significance to many organisations and institutes around the globe. As the usage of the www continues to increase it has become the most commonly used platform for users and customers of services and products to discuss their views and experiences. The nature of this www discussion can significantly influence the perception and hence the success of a bra...

Reputation Speculation behavior means that the buyers and sellers collaborate with each other to make fake transaction and give positive feedbacks in order to raise reputation level of online shops. This paper finds that reputation speculation is widely adopted and becomes an industry in China, making the consumers distrust the reputation of online stores, which is not conducive for the long-te...

With the rapid growth of cloud computing, the importance of a reputation system for cloud computing services has attracted a lot of attention. Building an objective and reliable reputation scheme has been crucial to promote the development of cloud computing. To address the challenges of reputation evaluation in cloud computing, including the diverse nature of cloud services and intricacy of ma...

It is proposed that through the formalization of concepts related to trust, a more accurate model of trust can be implemented. This paper presents a new model of trust that is based on the formalization of reputation. A multidisciplinary approach is taken to understanding the nature of trust and its relation to reputation. Through this approach, a practical definition of reputation is adopted f...

Reputation plays a central role in human societies. Empirical and theoretical work indicates that a good reputation is valuable in that it increases one's expected payoff in the future. Here, we explore a game that couples a repeated Prisoner's Dilemma (PD), in which participants can earn and can benefit from a good reputation, with a market in which reputation can be bought and sold. This game...

Interest for computational trust and reputation models is on the rise. One of the most important aspects of these models is how they deal with information received from other individuals. More generally, the critical choice is how to represent and how to aggregate social evaluations. In this article, we make an analysis of the current approaches of representation and aggregation of social evalu...

One should never sleep during day-time after eating. Such sleep excites phlegm and bile and brings on such diseases as jaundice, painful headaches, languor and unsteadiness, as also heaviness of the limbs, loss of lightness of the body, loss of appetite, dropsical swellings, hiccough, inflammation of the Schneiderian membrane, loss of memory and intelligence, hemicrania, urticaria evanida, erup...

he purpose of this work is to introduce and study the concept of minimal deterministic automaton with IF-outputs which realizes the given IF-language. Among two methods for construction of such automaton presented here, one is based on Myhill-Nerode's theory while the other is based on derivatives of the given IF-language. Meanwhile, the categories of deterministic automata with IF-outputs and ...

than the left side, no pain except on pressure, when it was slight ; the greatest girth of the abdomen was 34 inches. There was difficulty of breathing, feeble pulse, anaemia, emaciation and debility, as the result evidently of the adventitious growth occurring in a weakly constitution. There was no anasarca, though the urine was scanty ; ill-defined pains shooting down the legs were complained...
