Is there a way with Watson to identify input.text's that have no entities at all?
I don't need to know anything about the input.text, I just need to know if it does or doesn't have an entity.
You can find out whether any Entity got identified or not, only from the entities array from the response. If this array is empty, then no entity got identified from the input.text, else some entities got identified.

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.
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 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.
I have an intent that requires the user to give a path:
plot the file in /home/user/path
Is there a way to extract the path with dialogflow and to get its value into an entity? I think that this case cannot be approached with synonyms.
NO, as DialogFlow doesn't support Regex in entities, there is no easy way to parse path value in DialogFlow using entity.
You have two options to parse Paths into an entity.
One: Use #sys.any entity in place of the path and on fulfilment side check if the value of the entity is actually a valid path or not using Regex.
Two: Create your own entity for paths and use DialogFlow Agent-API to keep updating values in that entity whenever new file/folder is created/updated/deleted in whatever file system you are working on. (Yeah this sounds crazy but I don't think there are any other options to achieve what you want)
Total newbie question now... Suffice to say, I have searched for a completely noddy explanation but have not found anything 'dumb' enough. The problem is...
I have created a core data stack in which I have a entity called 'Client' and an entity called 'Car'. It is a one-to-many relationship.
So far i have successfully created and fetched the client list using code from apple's tutorial. Once I select a client, I then push a new tableViewController which should list the Cars for that chosen client.
First question...
I am used to sql style database programming where if I wanted to add a car to a client, I would simply add a 'ClientID' tag to the 'Car' record thereby providing the relationship to a specific client. How do I do the equivalent in core data? My understanding from my reading is adding attributes to point to other entities isnt necessary - core data maintains this relationship for you without needing additional attributes in the entities.
Second question...
As and when I have created a 'car' entity and successfully linked it to a 'Client'. How to I create a fetch which will retrieve just THAT client's cars. I could alter the code from apple to fetch ALL cars but I don't know how to fetch cars associated with a given client. From my reading, I think I need to use predicates, but apples predicate documentation stands alone and does not give clear guidance on how to use it with core data
I realise how noddy this is, but I cant find an idiots guide anywhere...
Any help/code exmaples much appreciated.
OK, I have answered my own question. For those who have found my question and would like to know the answer, it is extremely simple...
Firstly, to create a 'Car' and associate it with a 'Client'. Firstly create a 'Car' as you normally would and simply add this line of code...
newCar.client = client;
This sets the 'client' relationship on the 'Car' record to the client in question.
Secondly, I had thought that if you had a client and needed to find their cars, you would need a new fetch. But not so! Simply use the following lines of code...
NSSet *cars = client.cars;
[self setCarsArray:[cars allObjects]];
The first line uses "client.cars" o follow the object graph to determine the cars this client has and populates them in an NSSet. The second line then populates a NSArray which is declared in the current viewcontroller which can be used to for display purposes.
Sorted!!
