These are the data sets does not follow one of the postulates established by Euclid specially the parallel postulates. In this case, the precise representation of these data sets is major issues for knowledge processing tasks. Hence, the current paper tried to introduce some non-Euclidean geometry or Anti-Geometry methods and its examples for various applications.  2021 2021 24 33 10.54216/JNFS.010102 https://www.americaspg.com/articleinfo/24/show/884
