回复: 有关hedge的定义
"hedge" is not a well-defined terminology. 动态语法's suggestion was to tell you to focus on the group of words not the strict definition of the term, since the term is too hard to define.

Linguistic Hedges
Fuzzy sets can be used to represent qualitative linguistic terms (notions) like ``short'', ``long'', ``expensive'', etc. in terms of membership functions define in numerical domains (distance, price, etc.). By means of linguistic hedges (linguistic modifiers) the meaning of these terms can be modified without redefining the membership functions. Examples of hedges are: very, slightly, more or less, rather, etc. Hedge ``very'', for instance, can be used to change ``expensive'' to ``very expensive''. Two basic approaches to the implementation of linguistic hedges can be distinguished: powered hedges and shifted hedges. Powered hedges are implemented by functions operating on the membership degrees of the linguistic terms [ZimmermannZimmermannZimmermann, H.-J.1996]. For instance, the hedge very squares the membership degrees of the term which meaning it modifies, i.e., 123#123. Shifted hedges [LakoffLakoffLakoff, G.1973], on the other hand, shift the membership functions along their domains. Combinations of the two approaches have been proposed as well [NovákNovákNovák, V.1989,NovákNovákNovák, V.1996].
