Certain and possible XPath answers
Sara Cohen, Yaacov Y. Weiss · 2013
Formulating an XPath query over an XML document is a difficult chore for a non-expert user. This paper introduces a novel approach to ease the querying process. Instead of specifying a query, the user simply marks positive examples χ+ of nodes that fit her information need. She may also mark negative examples χ− of undesirable nodes. A deductive method, to suggest additional nodes that will interest the user, is developed in this paper.
