DESCRIPTION
Project LASSO intends to deploy, improve and extend Linked Data (LD) infrastructure in three different use cases. Central feature of all use cases is a lookup service which helps to augment already existing, formalized knowledge with facts from the Linked Open Data (LOD) cloud. These three use cases are Semantic Desktop, Enterprise Collaboration and Inspiration Services. Currently available systems in all of these application domains are sparsely using data from the Semantic Web.http://www.lassoproject.org/
