Mix [String]

Description

Combines strings from several inputs into a single output. Multiple merging/aggregation-techniques can be selected using the parameters.

Input

  • MIXLIST [STRING]: one or more inputs that should be combined

Output

  • RESULT [STRING]: the combined output of all inputs in a single column

Parameters

  • Score normalization

    • None: don’t change probabilities as they come in
    • Max: divide by the maximum score in each input
    • Standard: performs standard score normalization "combSUM score combination" (J.H.Lee, 1997)
  • Score combination

    • Disjunctive: objects must occur in at least 1 input (default)
    • Conjunctive : objects must occur in all inputs
  • Score aggregation: defines how the output scores are calculated (when an instance occurs in multiple inputs)

    • SUM: sums the weights of the individual inputs. Use SUM if the signals are completely independent (default)
    • MAX: selects the highest weight of the object. Often used in combination with Conjunctive.
    • MIN: selects the lowest weight of the object
    • PROD: multiplies of the individual inputs. Often used in combination with Conjunctive.
    • AVG: selects the average weight of the object (only over inputs that contain the input)
    • DISTINCT: aggregates evidence (formula: 1 - prod(1 - p))
    • ALL: don't aggregate, and output all tuples from all inputs as is
