Extract Dates
Description
Extracts date values from an object for a specific property. The property should be provided as a parameter. With additional blocks, the extracted values can for example be used to rank results.
Input
SOURCE [OBJ]: a list of objects
Output
PAIR [OBJ,DATE]: for each object in the input source, the extracted date value is provided as the second column in[OBJ,DATE]. When multiple values can be extracted for an object, each object-value pair is returned as a separate result.RESULT [DATE]: the extracted values, disjoint from their parent object. Use the score aggregation parameter to define how occurrences of the same values are handled.
Parameters
Property: the property to extract the values from. Use*to extract values from all propertiesUse sub-properties: when set totrue, the values of all sub properties are also included. Sub-properties can be defined in the data with therdfs:subPropertyOfrelation.
Output scores can be aggregated and/or normalized.
