Current automated negotiation models assume that users know the value of the product or service they want to buy and provide their agents with a reservation price, and the agents make offers and reach agreements with other agents according to this reservation price. However, in real world electronic marketplaces users probably do not know the exact value of the item, which is in terms of price, and the reservation price they set to their agents only means the maximum price they are willing to pay for the item. In this paper, we propose a negotiation model to deal with the valuation problem. The shopping agent in our model can deliberate the market price and the seller agent’s reservation price from public available information and the seller agent’s proposals. Also in order to conform with the real world negotiation conditions, we introduce negotiation features of real world human shopping such as multiple sellers, valuation, ultimatum, and learning from available information, etc. into our model.展开更多

Nowadays Fashion Films are reinforcing the power of fashion images, building up new brand experiences for net-consumers： they are painting new worlds for fashion brands thanks to the old cinematographic language mixed to recent Internet logics. Starting from this observation, our main question was： Can we talk about a new fashion net-aesthetics for these new fashion tales？ Using a semiotics approach, this study investigates how Fashion, Cinema and the Net come together, producing new aesthetics, with new languages and new imaginary in fashion. The result can be really visionary.展开更多
