Scientific projects as well as business applications are included into our survey. For our analysis, we use protocol category, degree of automation, number of attributes, number of positions, number of negotiations and mediation type as classification criteria. Projects are categorized and evaluated using these criteria. We find that the focus of application development and the needs of business practice differ. Three major challenges for electronic negotiations theory and practice are identified: degree of automation, application integration and semantic variety.electronicelectronic businesselectronic commerceelectronic negotiationsmarketsnegotiation support systemssoftware agentsText/Journal Article1861-8936
