Breathing Space is the first semantic web collaboration between scholarly societies. It is a pilot project that aims to explore the value to researchers of compiling and mining a critical mass of data within a discipline. The project collates content from the European Respiratory Society and the American Thoracic Society, who together account for 30% of citations within the field of respiratory medicine. Bringing all our articles together enables us to reveal important connections between articles, author and concepts to you. We have been supported in bringing you this project by semantic web experts Publishing Technology and digital marketing experts TBI Communications.
