Find f s.t. for any two object s1, s2 \in S , f(s1, s2) = 0 or 1 when 0 A!=B otherwise A=B

NED under the context of RDBMS

In case we are assuming the conctete situation that peforms NED over RDMBS, the NED have to be performed in two fold - one is inside-table-NED and the other one is betwee-table-NED

Inside-table-NED (also called "table semantic interpretation systems")

Such joint models are based on a strong assumption that the relations expressed can be mapped to the target KB, if not consider otherwise."

On Tabular, not Text

Most NED applied to Text data only, however, our task is required to perform over tabular data. Check AIDA which directly runs over postgres https://github.com/codepie/aida
