我们可以在Rasa Core Stories中使用通配符作为插槽值吗？

Question

I'm trying to get a reasonable understanding of how Rasa Core handles stories. I basically have 3 entities - occasion , relationship and gender

Based on the different values of each of these, I'd like to utter certain templates. However, there are times when say occasion is Christmas , and no matter what relationship or gender slots are filled with, I'd still want to use a certain template.

However, the only way I seem to get around this is by entering all permutation values of relationship and gender for a given value of occasion as Christmas .

Can I rather use something like this:

* suggest {"occasion": "Christmas", "relationship": *, "gender" : *}

I've tried a story line in Rasa with this:

* suggest {"occasion": "Christmas"}

However when I put in a query for "Where would you suggest I should take my brother for Christmas", Rasa NLU identifies the slot occasion as Christmas and relationship as brother , and my story line is never called, since now relationship is set to brother . I wouldn't say its intuitive to permute every possible combination for relationship with occasion as Christmas , rather I'd achieve this programatically through actions then. However, I just thought I'd be able to take the benefit of Rasa stories and understand the concept better.

Any help will really be appreciated.

Answer 1

Rasa Core currently does not a functionality for "wildcard" slots. However, I am not entirely sure whether this is actually needed.

Case 1: You want to utter different templates depending on which slots are filled. In this case you have to provide different stories (with the different combinations) to your training data.

Case 2: You don't care whether some slot is filled and want the bot to utter the same template. In this case I suggest to set the slot type of the ignored slots to unfeaturized as it is described here . unfeaturized will mean that is does not affect the stories whether these slots are set.
