Abstract:
In electronic business buyers and sellers should be able to interact with each others inside an architecture
that is easy to use and maintain. Electronic auctions are an interesting approach to achieve this goal by
bringing together business in the Web. Further the greatest benefits lie in cost reduction for buyers and
sellers. Technically, an electronic marketplace is a virtual place that resides somewhere in the Internet. They
can provide several types of business processes depending upon their target audience. A form of such
processes is e-procurement. E-procurement technology is any technology designed to facilitate the
acquisition of goods by a commercial or a government organization over the Internet. A form of eprocurement
is reverse e-auctioning. In such auctions the supplier that made the lowest offer wins the
auction. In this paper we describe the e-procurement system that we are developing. In particular we present
how taxonomies and user profiles can be utilized
in improving the effectiveness of the e-procurement
process. From technological point of view we present how suppliers’ Web services support e-procurement
specific operations, and how BPEL4WS (Business Process Execution Language for Web Services) can be
used in orchestrating these Web services. In addition, we present how UDDI (Universal Description,
Discovery, and Integration) registry can be utilized in storing the used taxonomies and the profiles of the
suppliers. In this way we can achieve high recall and precision fractions in searching relevant suppliers.
