In this paper, the authors study what semantic technologies can bring to the e-business domain and how they can be applied to it. After an overview of the goals to be achieved by e-business applications they detail a large panel of existing e-business standards, with a specific focus on B2B (Business To Business) and their current modus operandi. Furthermore they also present some of the most relevant e-business ontologies. They then argue that the use of semantic technologies will simplify the automatic management of many e-business partnerships. However the construction of ontologies brings a new level of complexity that might be facilitated by automating the great part of the generation process.
