AB - Abstract.The  phenomenon  was  understood  as  the  basic  element  to  constitute  knowledge  in  this  study, 
where  the  granular  structure  was  taken  as  the  basic  structure  of  phenomenon  formalized  representation. 
Based  on  the  isomorphism  between  formal  concept  analysis  and  rough  set  theory,  the  granular  structure 
model was established in conceptual category of phenomenon, and the correlation among concept categories 
was  given  as  well  as  correlation  distance,  proving  that  the  concept  element  space  induced  by  correlation 
distance  Θ  was  a  metrizable  space.  Based  on  the  conclusions  in  this  study,  the  knowledge  representation 
model can be established more completely than conceptual model in semantic description, providing a basis 
for phenomenon formalization research by using the topologic method.
