Keywords: Knowledge Extraction, Natural Language Processing, Frame Semantics, Knowledge Graphs, Linked Open Data

DescriptionFRED is a state-of-the-art tool for automatically extracting knowledge graphs from English (other languages via automated translation) text, and link them to existing knowledge. It can be considered a machine reader for the Semantic Web: it is able to parse natural language text, and transform it to linked data. It is implemented in Python, and available as REST service as well as a Python library suite [fredlib]. FRED background theories include: Combinatory Categorial Grammar, Discourse Representation Theory, Frame Semantics, and Ontology Design Patterns. FRED leverages Natural Language Processing components for performing Named Entity Resolution (using Stanbol and TagMe), Coreference Resolution (using CoreNLP), and Word Sense Disambiguation to DBpedia,, WordNet, VerbNet, and FrameNet. All FRED graphs include textual annotations and represent textual segmentation, expressed by means of EARMARK and NIF. Originally developed in the EU FP7 IKS project by CNR's STLab, it has been later improved also in the RCLN group at LIPN, Paris Nord University, and is currently maintained jointly by STLab and DHARC. FRED has been extended for Aspect-based Sentiment Analysis (Sentilo), type induction (Tìpalo), knowledge reconciliation (Mergilo), and synthetic relation extraction (Legalo).
