Using Data Crawlers and Semantic Web to Build Financial XBRL Data Generators: The SONAR Extension Approach

Algorithm 2

Affinity algorithm.

AFFINITY*(R, C) {

  Number affinity = 0;

  For each tuple “TUPLE<attribute, literal>” of the row “R” {

   For each of the semantic annotations “L” of the class “C” {

       If (“L” == “attribute”) then {

         return ∞;

        }

   }

   For each semantic annotations of class datatype properties “L”{

       affinity = Levenshtein(“L”, “attribute”) + affinity;

   }

   }

  return affinity;

}
