Tools
From STLab
STLab from ISTC-CNR has designed some semantic technology tools in the last years. They are referred jointly in this page.
FRED is a tool for automatically producing RDF/OWL ontologies and linked data from natural language sentences. The method is based on Combinatory Categorial Grammar, Discourse Representation Theory, Linguistic Frames, and Ontology Design Patterns. Results are enriched with NER and WSD. A paper on FRED. Designers: Francesco Draicchio (main developer), Aldo Gangemi, Valentina Presutti.
Tìpalo uses FRED and automatically assigns types to Wikipedia entities. Given a Wikipedia page URI, the tool returns an RDF graph composed of rdf:type, rdfs:subClassOf, owl:sameAs, and owl:equivalentTo statements providing typing information about the entity referred by the Wikipedia page. Designers: Francesco Draicchio, Aldo Gangemi, Alberto Musetti, Andrea G. Nuzzolese (main developer), Valentina Presutti.
Aemoo helps exploring Wikipedia knowledge in a twofold way. It implements filtering strategies based on Encyclopedic Knowledge Patterns (EKP), which have been extracted from the Wikipedia linking structure, showing alternatively "core" or "curious" knowledge about a Wikipedia entity. A paper on EKP, and another paper on Aemoo. Designers: Francesco Draicchio, Aldo Gangemi, Alberto Musetti (main developer), Andrea Nuzzolese (main developer), Valentina Presutti.
Wikifier resolves arbitrary named entities (i.e. either individuals or concepts) on Wikipedia. See Wikifier page for details on its parametrization and implemented method. Designers: Concetto Elvio Bonafede (main developer), Aldo Gangemi, Alfio Gliozzo.
