In this paper, we describe WikiOIE, a framework for extracting relations from Wikipedia. The framework is based on UDPipe and the Universal Dependencies project for text processing. It easily allows customizing the information extraction (IE) approach to automatically extract triples (subject, predicate, object). In this work, we propose two unsupervised IE methods to extract triples from the Italian version of Wikipedia. The former is based only on PoS-tag patterns; the latter also uses syntactic dependencies. The extraction process is provided in JSON format and is used to build a simple web interface for searching and browsing the extracted triples. A preliminary evaluation conducted on a dataset sample shows promising results, although the approach is completely unsupervised.

Abstract
In this paper, we describe WikiOIE, a framework for extracting relations from Wikipedia. The framework is based on UDPipe and the Universal Dependencies project for text processing. It easily allows customizing the information extraction (IE) approach to automatically extract triples (subject, predicate, object). In this work, we propose two unsupervised IE methods to extract triples from the Italian version of Wikipedia. The former is based only on PoS-tag patterns; the latter also uses syntactic dependencies. The extraction process is provided in JSON format and is used to build a simple web interface for searching and browsing the extracted triples. A preliminary evaluation conducted on a dataset sample shows promising results, although the approach is completely unsupervised.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
