Previous methods for extracting attributes (e.g., capital, population) of classes (Em- pires) from Web documents or search queries assume that relevant attributes oc- cur verbatim in the source text. The ex- tracted attributes are short phrases that correspond to quantifiable properties of various instances (ottoman empire, ro- man empire, mughal empire) of the class. This paper explores the extraction of non- contiguous class attributes (manner (it) claimed legitimacy of rule), from fact- seeking and explanation-seeking queries. The attributes cover properties that are not always likely to be extracted as short phrases from inherently-noisy queries.
