In addition, to test the external validity of the model, the model is used to predict the occurrences of instances in other data set. The model is applied in 40
instances which are taken from Time Magazine Corpus and is able to correctly predict 34 out of 40. It shows that the external validity of the model is still
relatively high, which is 85, when applied to other similar situations in real world, in this case in Time Magazine Corpus situationsee appendix 6.Two
examples are brought up from the Time Magazine Corpus data set.

The result shows the tendency of the instance to take benefactive PP construction is 0.28843. The number shows that it is less than 0.5 to take
95
benefactive PP, so the model predicts that the occurrence is in double object construction. In this instance, the predicted construction matches the observed
construction. In this very case, the model is externally valid. 28

The result shows the tendency of the instance to take benefactive PP construction is 0.99966. The number shows that it is more than 0.5 to take
benefactive PP, so the model predicts that the occurrence is in benefactive PP construction. In this instance, the predicted construction matches the observed
construction. Once again, the model predicts accurately and is proven to be externally valid.
