Extracting Relations from Italian Wikipedia using Self-Training

This dataset contains relations extracted from the Italian Wikipedia by the WikiOIE framework.
WikiOIE 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).
This dataset contains relations extracted by a supervised approach based on self-training. 
The extraction process is provided in JSON format.

Version 2 of the dataset was extracted using an improved version of the learning algorithm. The files of version 2 are identified by the suffix "_reg" in the file name.
