‘deleteFilterValue’ is useful to deal with a scenario where the user requests to remove a filter that they have already put on specifically. For example, “I wish to remove the onion filter”, “Forget about excluding broccoli”, and “Can you delete the Chinese cuisine”. Add some training phrases with all the different filters that could be deleted.
It is thus important that in your training phrases, you include a variety of all filter-related entities and that these entities are also given specific values and parameter names in the Action and Parameters tables. These entities are given new parameters and value names in order to identify them as a filter to be deleted. Specifically, you tag the entity in your training phrases as normal and then you change the parameter name and value name to “entitynameDel”. Your entity table under Action and Parameters should look like this when you are done.
