Dear Yu, nice to find you well. Concerning question about wikipedia, if you mean the automatic typing/linking, that is one of the things we are doing. For a small subset, just make use of the REST API of Tipalo (documentation will be online soon).
Concerning GO, a paper on Tipalo and its architecture will appear soon, at least as a technical report, and you can see where to put a GO component for doing that. You may need a WSD (Word Sense Disambiguation) component trained on GO for best results, if disambiguation is not a big issue for biomolecular domain, then you need at least a data linking (or ontology matching) component.
Best Aldo

I want to generate a subset of wikipedia into OWL/RDF.
I would like to use your tools to try, but the entities I am interested are from GO or any other biomedical ontologies.
I wonder if I could change the ontology component of your tools.
Thanks,
Yu Lin ( one of your students from SSSW2008)

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/fredA 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/tipaloA 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 stlab@xxxxxxThe STLab team [11] Designers and developers of Tipalo and FRED are: Aldo Gangemi, Valentina Presutti, Francesco Draicchio, Alberto Musetti, Andrea Nuzzolese
