I took some notes while trying FRED : http://deductions-software.blogspot.fr/2012/07/trying-fred-tool-for-producing-rdfowl.html
FRED is a nice tool, but ATTEMPTO [1] is still more accurate when it comes to real logic based sentences. [1] ATTEMPTO http://attempto.ifi.uzh.ch/site/description/ 2012/7/12 valentina presutti <[email protected]>: > Dear all, > > We are pleased to announce the release of two new tools: FRED and Tipalo. > Online demonstrators are available from the STLab tools page [0] that > collects our software releases. We invite you to play with them, and provide > your welcome feedback: > > FRED - http://wit.istc.cnr.it/stlab-tools/fred > A tool for automatically producing RDF/OWL ontologies and linked data from > natural language sentences, currently limited to English. > FRED is based on C&C [1] and Boxer [2], a NLP tool that transforms natural > language text into a logical form compliant to Discourse Representation > Theory. We process Boxer output and apply a set of heuristics and semantic > transformations in order to obtain RDF designed for the Semantic Web. In this > process, we emphasize the relation to linguistic frames, supporting FrameNet > and VerbNet vocabularies, and to ontology design patterns. > In order to further improve interlinking of FRED results with LOD, a number > of features are under testing (they are already available in the Tipalo > tool), including Named Entity Resolution (based on Apache Stanbol [3]) and > Word Sense Disambiguation (based on UKB [4]). FRED results are available as > n-triples or graphs. A paper on FRED will be presented at next EKAW2012 [5]. > > Tipalo - http://wit.istc.cnr.it/stlab-tools/tipalo > A tool that automatically assigns types to Wikipedia entities in a > LOD-intensive graph. Given a Wikipedia page URI, the tool returns a RDF graph > composed of rdf:type, rdfs:subClassOf, owl:sameAs, and owl:equivalentTo > statements providing typing information (organized into class taxonomies) > about the entity referred by the Wikipedia page. Currently, entity types are > derived from the text, and aligned to the DBpedia Ontology [6], WordNet 3.0 > in RDF [7], DUL [8], and DolceZero [9]. The tool relies on FRED (including > NER and WSD), hence it has unlimited domain coverage (i.e., it is independent > from the completeness of specific ontologies). Results are available as RDF, > HTML (with LODE [10]), and graphs. A paper describing Tipalo is currently > under review. > > Each tool is described in more detail in dedicated documentation. > > Enjoy! > > Feedback welcome to [email protected] > > The STLab team [11] > > Designers and developers of Tipalo and FRED are: Aldo Gangemi, Valentina > Presutti, Francesco Draicchio, Alberto Musetti, Andrea Nuzzolese > > This work has been partly supported by EU IKS project [12] and developed in > collaboration with the Computer Science department of the University of > Bologna [13]. > > [0] http://with.isct.cnr.it/stlab-tools/ > [1] http://svn.ask.it.usyd.edu.au/trac/candc > [2] http://svn.ask.it.usyd.edu.au/trac/candc/wiki/boxer > [3] http://incubator.apache.org/stanbol/ > [4] http://ixa2.si.ehu.es/ukb/ > [5] http://ekaw2012.ekaw.org/node/137 > [6] http://dbpedia.org/Ontology > [7] http://semanticweb.cs.vu.nl/lod/wn30/ > [8] http://www.ontologydesignpatterns.org/ont/dul/DUL.owl > [9] http://www.ontologydesignpatterns.org/ont/d0.owl > [10] http://www.essepuntato.it/lode > [11] http://stlab.istc.cnr.it/stlab/People > [12] http://iks-project.eu/ > [13] http://www.informatica.unibo.it/ -- Jean-Marc Vanel Déductions SARL - Consulting, services, training, Rule-based programming, Semantic Web http://deductions-software.com/ +33 (0)6 89 16 29 52 chat : irc://irc.freenode.net#eulergui
