DESCRIPTION:We present novel evidence that abstract and concrete concepts 
 are organized\nand represented differently in the mind\, based on analyses
  of thousands of\nconcepts in publicly available datasets and computationa
 l resources. First\,\nwe show that abstract and concrete concepts have dif
 fering patterns of\nassociation with other concepts. Second\, we test rece
 nt hypotheses that\nabstract concepts are organized according to associati
 on\, whereas concrete\nconcepts are organized according to (semantic) simi
 larity. Third\, we\npresent evidence suggesting that concrete representati
 ons are more strongly\nfeature-based than abstract representations.  We ar
 gue that degree of\nfeature-based structure may fundamentally determine co
 ncreteness\, and\ndiscuss the implications for both cognitive and computat
 ional models of\nmeaning.
