Returning invalid values when input is wrong

[sebastianmika]

Hi,

thanks for sharing your feedback. However, I am afraid there is no straight forward solution to your problem, at least none that I am seeing. ctparse by nature is not perfect but rather tries to generate the best possible match. I.e. as long as there is one rule that generates at least one production, that will be returned.

To mitigate your issue you can build auxiallary logic on the meta data in the response:

res = ctparse("how are you?")
# the score can be understood as log-quality - very small values like this are a sign of low quality
res.score
# how much of the original text was used for this response? If that is just a small part (here 1/4) there is likely something fishy
len(res.resolution) / len("how are you?")

I hope that helps.
