Acquisition of Noncontiguous Class Attributes from Web Search Queries
MARIUS A. PAŞCA · 2014
Previous methods for extracting attributes (e.g., capital, population) of classes (Empires) from Web documents or search queries assume that relevant attributes occur verbatim in the source text.The extracted attributes are short phrases that correspond to quantifiable properties of various instances (ottoman empire, roman empire, mughal empire) of the class.This paper explores the extraction of noncontiguous class attributes (manner (it) claimed legitimacy of rule), from factseeking and explanation-seeking queries.The attributes cover properties that are not always likely to be extracted as short phrases from inherently-noisy queries.
