The Semantic Technology Laboratory (STLab), within the Institute for Cognitive Sciences and Technology (ISTC) of the Italian National Research Council (CNR), has been founded in the Autumn of 2008, and partly originates from the past Rome branch of the Laboratory for Applied Ontology.


The Lab performs R&D in semantic technologies. Besides its European and Italian research projects, it has one motivating use case in the development of semantic web applications for the CNR scientific organization, jointly with the Information Systems Unit of CNR.


STLab people include either local collaborators working partly or full time for the Lab, or external people that share R&D interests with the Lab. The founders are Aldo Gangemi (scientific coordinator), Alfio Gliozzo, Valentina Presutti, and Alberto Salvati (technology coordinator).
