NifExtractor

class NifExtractor extends WikiPageExtractor

Extracts page html.

Based on AbstractExtractor, major difference is the parameter apiParametersFormat = "action=parse&prop=text&section=0&format=xml&page=%s"

This class produces all nif related datasets for the abstract as well as the short-, long-abstracts datasets. Where the long abstracts is the nif:isString attribute of the nif instance representing the abstract section of a wikipage.

We are going to to use this method for generating the abstracts from release 2016-10 onwards. It will be expanded to cover the whole wikipage in the future.
