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

Algorithm 3

Algorithm to create instances of a particular class or group of classes.

CREATE_INSTANCES (R,G) {

  For each Class “C” of G {

  Instance c = new Instance from Class “C”;

  Number num = 0; Indicates the number of attributes initialized on c.

   For each Datatype Property “P” of Class “C” {

     For each Tuple “TUPLE<attribute, literal>” from Row “R” {

      If the Class “C” contain the “attribute” {

       For each label “L” from “attribute” from Class “C” {

          If (“L” == “literal”) {

           Add “literal” to “attribute” of Instance “c”;

           num = num + 1;

           }

       }

       }

      }

   }

   }

  If (num > 0) {

   Add the Instance to Domain Ontology;

   }
