Extract [Integers,Strings]

Description

Extracts int, string values from an object for specific properties.

Input

  • SOURCE [OBJ]: a list of objects

Output

  • TUPLE [OBJ,INT,STRING]: for each object in the input source extract the requested attributes.
  • RESULT [INT,STRING]: the extracted values, disjoint from their parent object. Use the score aggregation parameter to define how occurrences of the same value are handled.

Parameters

  • Integer Property: the property to extract the integer values from.
  • String Property: the property to extract the string values from.
  • Language: when a language is selected, only the strings in this language are extracted. This uses the language tags that are defined in the data.
  • Use sub-properties: when set to true, the values of all sub properties are also included. Sub-properties can be defined in the data with the rdfs:subPropertyOf relation.

Output scores can be aggregated and/or normalized.
