Abstract. Price is the omnipresent factor that determines buyers ’ and sellers’ decision-making when trading products in real and virtual marketplaces. However, since a fixed price can often lead to unsuccessful transactions, in practice market players normally have price ranges in their minds, which imply some concessions when finding potential buyer-seller matches. In this paper, we propose a price-range similarity measure that is justified by price-range overlaps between buyers and sellers in several possible cases. Working independently, our price-range similarity measure provides a buyer (seller) with a list of ranked sellers (buyers) according to their price-range similarity values. Embedded into a similarity algorithm, our price-range similarity measure contributes, in a controllable way, to the overall similarity measures of products/services.

Range Similarity Measures between Buyers and Sellers in e-Marketplaces

Price is the omnipresent factor that determines buyers' and sellers' decision-making when trading products in real and virtual marketplaces. However, since a fixed price can often lead to unsuccessful transactions, in practice market players normally have price ranges in their minds, which imply some concessions when finding potential buyer-seller matches. In this paper, we propose a price-range similarity measure that is justified by price-range overlaps between buyers and sellers in several possible cases. Working independently, our price-range similarity measure provides a buyer (seller) with a list of ranked sellers (buyers) according to their price-range similarity values. Embedded into a similarity algorithm, our price-range similarity measure contributes, in a controllable way, to the overall similarity measures of products/services.Le prix constitue le facteur primordial qui d\ue9termine la prise de d\ue9cisions par les acheteurs et les vendeurs lors de la n\ue9gociation de produits dans les march\ue9s r\ue9els et virtuels. Toutefois, comme un prix fixe risque de mener souvent \ue0 des transactions infructueuses, les intervenants du march\ue9 ont en t\ueate dans la pratique et normalement des plages de prix, ce qui suppose quelques concessions lorsque vient le temps de trouver des concordances possibles entre les acheteurs et les vendeurs. Dans ce document, nous proposons une mesure des similitudes des plages de prix qui est justifi\ue9e par les chevauchements des plages de prix entre les acheteurs et les vendeurs dans plusieurs cas possibles. Fonctionnant de mani\ue8re ind\ue9pendante, notre mesure des similitudes des plages de prix offre \ue0 un acheteur (un vendeur) une liste des vendeurs (acheteurs) class\ue9s par rang, selon les valeurs des similitudes des plages de prix. Int\ue9gr\ue9e \ue0 un algorithme de similitudes, notre mesure des similitudes des plages de prix contribue, de mani\ue8re contr\uf4lable, aux mesures globales des similitudes des produits/services.NRC publication: Ye
