I want to create an entity that has any value except the values that are defined in another entity.
For example, i have an entity that contains all the possible products categories that i use in the bot, and if the user type a value that is not in that entity i want to react in some way.
It's like a fallback but only triggered when that condition is met.
Any suggestion?
Entity extraction is based on some definite value that can be identified and separated. There should be some basic features defined for the agent to train on. Based on these trained features, the agent will look for an entity and extract it from the user's response.
If you have already defined an entity to look for, it will be extracted by the Dialogflow based on the training data. If there is nothing defined it will not be identified as an entity as the agent will be not sure what to look for.
So, what you can do is,
Make the entity (already defined) as not required. Uncheck the "required" checkbox in the Dialogflow.
Add the "#sys.any" in the Entity you defined and make it a composite Entity with the combination of your Entity and "#sys.any" something in the line of
Train your agent to look for this new Entity with your Basic Entity data and Anything else data.
Collect this in the webhook.
OR
You when you want to collect anything else, you can collect user utterance from the agent object and parse the data using Regex pattern of your choice.

When I created A Parameter and I assigned it to te entity called #sys.unit-information-name,
I keep getting this warning: *The annotated text 'diabetes' in training phrase 'show me results on diabetes' does not correspond to entity type '#sys.unit-information-name'. And as a result my chatbot does not give me the right result, basically it will just keep asking the question under the Prompts under the Action and parameters.
If I remove this parameter it works. But I want to use the parameter & Entity
Any Help
Thanks
The problem you are facing is because you are explicitly creating a parameter and adding the system entity #sys.unit-information-name. This entity is used to refer to information about units as per system Entities documentation.
Since you are referring to a disease “diabetes” as per your expression “show me results on diabetes”, this entity cannot be used to map diabetes or any other disease also. There is no system Entities for Diseases, so it's better that we create a custom entity defining most of the disease names.
When giving the training Phrases if the word matches with values defined in entity, then entity mapping for that word will be done and the response will be generated.
I have an entity called 'Vehicle', inside there are different values like 'Car', 'Motorcycle' or 'Truck'.
I want the intent to trigger only if detects a Entity Vehicle with value 'Truck'.
In this pic I show the configuration of my intent. The problem is that will trigger with any value which is a Vehycle
How can I fix it without using fulfillments?
Don't use entities in this case. The issue is that an entity will match any instance of that entity.
If you only want to match 'Truck', add that in your training phrases and then add a parameter named Vehicle with the value Truck, without using an entity. Like so:
Notice that Truck is not highlighted and the Entity field is empty.
Since #sys.airport only exists for the default English locale, I want to create a custom entity that emulates it for other locales.
From what I've read here, you can put subentity types into the value fields, say, the system entity #sys.geo-city:city and a custom entity #usr.iata-code:iata, and it will match either one or the other.
But I don't understand how you would tell Dialogflow which city and which IATA code go together, so that Dialogflow (ES) would know to send the complete object {"city":"Amsterdam", "iata": "AMS"} to the webhook after matching either "Amsterdam" or "AMS", as it does happen with #sys.airport.
Thanks for any input!
It will be difficult to create a custom entity that works just like #sys.airport. The #sys entities are special and can do somethings custom entities can't, for instance, pairing values together.
As you pointed out, you can put multiple entities together in one single entity by using Composite Entities, but the only thing this does is allow you to recognize two values made up from other #sys or custom entities in a single entity. It doesn't give you the option to create pairs between the values of the entities.
If you would want to create something like this, you would need some code that does a look up in a dictionary or list. So when "AMS" is matched, the code fills in the missing property "Amsterdam" or vice versa.
I have an issue developing an agent with dialogflow (api.ai). I am using a lot of entity values which are all different from one another. however there are similar synonyms for some entity values but the agent is returning only one value.
How can i get all the possible matches or ask question to resolve the ambiguity
for example i have an intent like: tell me the location of ABC express train
if my entity values are :
entity synonym
15127 ABC express
12345 ABC express
I want it to return two values or ask question to resolve such ambiguity
how can i work this out
Thanks in advance
If you enable fulfillment for this intent, you can take a look at the value the user said and ask a further question if you need to disambiguate between entities.
Let's imagine you are extracting an entity called "trains". The parameters table in your intent might look like this:
By default, if the user says ABC express, the fulfillment webhook will be called with the following parameter hash:
"parameters": {
"trains": "15127"
}
This isn't enough information to decide if the request was ambiguous, since train 15127 might also have non-ambiguous synonyms.
You can configure Dialogflow to send the original text of the entity, alongside the resolved value. This means you will receive the following information to your webhook:
"parameters": {
"trains": "15127",
"original": "ABC express"
}
You can then use some simple logic to ask a further question if the value of original appears in a list of known ambiguous synonyms.
To have Dialogflow send this data, modify your parameters table so it looks like the following:
This will cause the original synonym to be sent to Dialogflow alongside the resolved value.
I am designing an application that will display dynamically-generated forms to the user who will then enter values into the form fields and submit those values for persistence. The form represents an employee evaluation.
One use case allows an administrator (from HR) to define the form fields. They should be able to create a new form, add/remove fields from a form and mark a form as 'deleted'.
The second use case is when a manager views the form and enters values into the form fields for a specific employee. They should be able to save the values at any time and recall the saved values when viewing the form again for the same employee.
Finally, when the manager is satisfied with the values they've entered for that employee, they can 'submit' the form data which persists the flattened data into the data warehouse for reporting purposes. When this is done, the 'working' copy of the data is removed so the form will display empty the next time they view it for that employee.
I am not concerned with the front-end at this point and working on the back-end service application that sits between the client and the data store. The application must provide a course-grained interface for all of the behavior required.
My question is how many aggregate roots do I actually have (and from that, how many repositories, etc)? Do I separate the form definition from the form data even though I need both when displaying the form to the user?
I see two main entities, 'EmployeeEvaluationSchema' and 'EmployeeEvaluation'. The 'EmployeeEvaluationSchema' entity would have a collection of 'FieldDefinition' value objects which would contain the properties that define a field, the most basic being the name of the field. The 'EmployeeEvaluation' entity would have a collection of 'FieldValue' value objects which contain the values for each field from the definition. In the simplest case, it would have a field name and value property. Next, the 'EmployeeEvaluation' could have a reference to 'EmployeeEvaluationSchema' to specify which definition the particular evaluation is based on. This can also be used to enforce the form definition in each evaluation. You would have two repositories - one for each entity. If you were to use an ORM such as NHibernate, then when you retrieve a 'EmployeeEvaluation' entity, the associated 'EmployeeEvaluationSchema' would also be retrieved even though there is a dedicated repository for it.
From your description it sounds like your objects don't have any behavior and are simple DTOs. If that is the case maybe you should not bother doing DDD. Can you imagine your entities without having getters? There are better ways to do CRUDish application than DDD. Again this is only valid if your "domain" does not have relevant behavior.
