Semantic Technology Laboratory

The Semantic Technology Laboratory (STLab) makes applied and basic research on semantic technologies as a hybridisation of Semantic Web, (linked) data semantics, NLP, lexical resources, cognitive semantics. Applications include organisational knowledge engineering (competence management, data integration, semantic CMS), knowledge extraction from text and data, empirical research on knowledge patterns, ontology design methods and tools.

What? 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 (

Why? The Lab aims at performing research and development 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 and Italian Public Administration, jointly with the Information Systems Unit of CNR.

Who? 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 (see also people page). The founders are Aldo Gangemi (scientific coordinator), Alfio GliozzoValentina Presutti, and Alberto Salvati (technology coordinator). Researchers include also Alessandro Adamou (PhD), Andrea Nuzzolese (PhD), Paolo Ciancarini (associate researcher), Eva BlomqvistFrancesco Draicchio, Alberto Musetti, Antonio d'Agata, Enrico Daga, Gianluca Troiani, Geri Steve, Claudio Baldassarre, Stefania Capotosti. Former researchers include Jos Lehmann (currently at Un. of Edinburgh), Carola Catenacci, Massimilano Ciaramita (currently at Google Research), Malvina Nissim (currently at Un. of Bologna), and Alfio Gliozzo (currently at IBM Watson Research Center).

Know How STLab competences include methods, best practices, tools and reusable models for ontology design, linked data, knowledge engineering, Web science, natural language processing, and knowledge extraction that hybridizes ontology and natural language engineering.

Themes Current research at STLab (see also research page) focuses on the following aspects of semantic technologies: Semantic Web and Web of Data (Web 3.0); ontology design patterns; empirical knowledge engineering; semantic search and corporate knowledge management based on ontologies and linked data; ontology-driven document generation and semantic wikis; collaborative tools for ontology design; adaptive eLearning; semantic interoperability.

Applications Typical application domains include organizational, business, industrial, legal, biomedical, e-government, and agricultural information systems. The Web is the main context for STLab technologies and data.
