However, many of these systems are often nothingmore than electronic product or service catalogues. Against this background,it is argued that new generation systems based on automaticnegotiation will emerge. This paper covers a particular kind of automaticnegotiation systems, where a number of participants in a mobiledynamic electronic marketplace automatically negotiate the purchase ofproducts or services, by means of multiple automated one-to-one bargainings.In a dynamic e-marketplace, the number of buyers and sellersand their preferences may change over time. By mobile we mean thatbuyers in a commercial area may initiate simultaneous negotiations withseveral sellers using portable devices like cell phones, laptops or personaldigital assistants, so these negotiations do not require participants to becolocated in space. We will show how an expressive approach to fuzzyconstraint based agent purchase negotiations in competitive trading environments,is ideally suited to work on these kind of e-marketplaces. Anexample of mobile e-marketplace, and a comparison between an expressiveand an inexpressive approach will be presented to show the efficiencyof the proposed solution.
