  13. 2017/08/18 State  of  the  Map  2017  Lightning  Talk 19 Findings

     and  Issues • A  lot  of  Notes  find  major  cities  such  as  Tokyo   and  Osaka  with  are  also  in  Hokkaido  and   Ishikawa  prefectures. • However,  many  of  the  users  were  “anonymous”.   and  there  was  a  tendency  to  post  bugs  by   MAPS.ME  and  Facebook. • The  user  interaction  (Notes  version)  between   the  OSM  mappers  are  still  in  a  small. • To  develop  a  method  to  extract  “Closed”   Notes.  Used  for  analysis  of  GIS  data  and   resolution  period. • It  is  necessary  to  analyze  the  contents  of   the  text  deeply  (text  mining  etc.).
