Automation of processes is a crucial factor for enterprises operating within a modern collaborative business environment. In order to ensure flexible operations, companies tend to build their IT systems in accordance with the SOA paradigm and take advantage of the Semantic Web technologies. The mentioned tendency especially in case of cooperating organizations requires support for automated service discovery and fast integration of discovered artefacts. Currently, one can easily find several initiatives that aim at automation of already pointed tasks. As a part of this work, we analyze a number of different frameworks that implement, support and facilitate interactions inherent to Semantic Web services and indicate their shortcomings. Having completed this survey, we propose a general model of SWS e-marketplace taking into account all important aspects that a featured model should provide. In order to achieve this goal, a set of features provided by the surveyed frameworks is compiled with a set of additional traits that were not considered before. Moreover, the model is enriched with economical requirements driven by service providers' and service requesters' needs.
