Suppose, I have questions about the product name, or ticket number or product id which are going to be unique every time. How to define intents for such questions and how to use entities to store it in a variable ?
For example:
For room booking intents, entities for room type could be single-bed room, double-bed room, king size bed or queen size.
Similarly, suppose for an enterprise product for bug tracking system, if I want to create entities for ticket number which could be anything (ex. TRS-6527).
Apologies, if this is very naive or unrelated questions.
You can define room_type entity using Create Entity in Entites section of your dialogflow console.
And train your intent by adding training phrases accordingly as below (Please Ignore the error here ):
Now you can access the room_type as a string in your fulfillment as params
app.intent('get_room_type', (conv, params) => {
const roomType = params.room_type;
// remember to use the same variable name that you defined as
// Parameter name in your intent to access in params
});
Similarly you can achieve for ticket number as well.
Refer this Codelab for example.
Hope that helps !

I have an entity (items) and its values are ('name', 'colour', 'awards')
I have three intents
Intent1 = Welcome Intent (user will get the options in the form of chips)
Intent2 = Select Option (bot will ask question to enter detail for selected option)
Intent3 = Update Option (bot will save the record and ask next option to update.)
Example -
bot: welcome! what you want to update? name, colour, awards.
user: name
bot: Enter your name.
user: John
bot: record updated, what to update next? name, colour, awards.
now the issue is awards have multiple fields to update, to update awards a user has to provide three things (award name, award date, award description)
What I want is when a user selects awards options from the chips then it should be taken to new intent where I will get all the data through slot filling.
The first thing to remember is that an Intent represents what the user has said and not what you are doing with what they have said. So it doesn't make sense to say that you are "going to an Intent".
Second, while slot filling seems like a good idea, it usually leads to further problems, since it doesn't handle conditional information well, or handle users if they skip around in what they want to update.
All of these are better solved by setting up a state machine where they are in the conversation, what information you need, and what they have provided so far. Based on these settings, you can prompt them yourself for what you expect next. (You may also find using one or several Dialogflow contexts useful for shaping how to accept results as well.)
So, for example, when the user has indicated they are updating the awards, it might work like this:
User: Awards
[Your fulfillment sets the 'awards' context with a parameter that we are prompting for the name.]
Bot: Ok, I'm going to need the award name, description, and when it was awarded. What is the name?
User: Merit
[This matches the Fallback Intent with an Input Context for 'awards', since it is free-form input. Your fulfillment stores this and sets the 'awards' context with a parameter that we are now prompting for the date.]
Bot: Got it, the award is named Merit. When was it awarded?
User: Today
[This matches an Intent with a training phrase of "<#sys.date>" and the Input Context of 'awards'. There are also training phrases for things like "It was awarded <#sys.date>" and so forth. Your fulfillment sets the date and sets the 'awards' context with a parameter that we're now prompting for description.]
Bot: Got it. Awarded on March 1st. What is the description?
User: They were awesome.
[This matches the Fallback Intent with the Input Context of 'awards' again, because it is still free-form input. Our fulfillment, however, knows that this is about the description this time, so it stores it and removes the 'awards' context since we've captured everything.]
Bot: I've recorded that as a description of "they were awesome" - sure thing. That was everything we needed for now. Do you want to update the name, colour, or awards next?
That all seems pretty straightforward. But consider if the conversation had gone this way:
User: Awards
[Your fulfillment sets the 'awards' context with a parameter that we are prompting for the name.]
Bot: Ok, I'm going to need the award name, description, and when it was awarded. What is the name?
User: [Having done this many times] They were given the award for Honor yesterday
[This might match an Intent with an Input Context of 'awards' and the training phrase of "Given the award for <#sys.any> <#sys.date>" and possibly "<#sys.date> they got an award for <#sys.any>". Your fulfillment sets the name and date from this, sees what information it still needs, and prompts with...]
Bot: Got it. Award named Honor. Awarded March 1. What is the description?
User: Actually, it is named Honorable Service
[This matches an Intent with a training phrase of "named <#sys.any>" and an Input Context for 'awards'. Your fulfillment changes the name stored, checks what we still need, and again prompts...]
Bot: Ok, I've changed the award name to Honorable Service. What is the description?
The first scenario could be handled by slot filling and simple prompting, but the second can't. Being able to handle more natural responses from people and more flexible prompting will be better for your users.
My app is giving user types of news based on the input. For ex: If user is saying what is happening in sports, so I give user sports news in the form of compound card. Now if user is saying that "Show me similar news", so all i need to do is pass the category id of that news to my other file and process that category id to get more same type of news. I am unable to pass the category id.
My news details file is NewsSearch.model.bxb and input i have taken is categoryName, which I convert into id and pass it to my api.
My similar News file is SimilarNews.model.bxb and input is categoryId, which I am supposed to pass to my api to get the same category news.
How to pass categoryId from NewsSearch.model.bxb to SimilarNews.model.bxb?
This is similar to a Continuation. If NewsSearch concept is not marked as transient, you can create an Action SearchSimilarNews that will take NewsSearch as the input. Since this is a followup query, NewsSearch will be available to the Planner from a historical perspective and will therefore be automatically passed into the input.

I have been working lately with Dialogflow to make chatbots to do some simple tasks. For instance with webhooks and youtube api where the user ask to show him a video and then the bot just answers with the youtube video url.
E.G.
USER SAYS
Show me Neil young harvest moon
AGENT SAYS
Here you go : https://www.youtube.com/watch?v=n2MtEsrcTTs
I do this by using a custom Entity I called "YoutubeQuery" I checked "Allow Automated expansion" and unchecked "Define Synonyms" then I just added 2 values "Kavinsky Night Call" and "Indigo Night Tamino"
In my Intent I just made a couple of training phrases like these:
And everything works.
Now my issue is with a new Agent which I called Orders
I want just to get Order Id's from the firestore database, but before getting there I'm running in kind of a huge problem
I defined the order's ID entity just like the one with the youtubeQuery. And I added some example Order ID's , I want them all to Start with OD and have 4digits after example (DX0001,DX0009,DX9999)
Afterwards I made the intent
Now unless I give the EXACT order ID's from the traininphrase or the ID examples I defined in the Entity it will always give me a response with an empty parameter OrderID
I start my intent by saying "my order" then I get prompted with "What is your ID?
So when I give an ID that has not been used in the training phrases of the Intent I get an empty value in the parameters like this:
But when I give an ID that has been used in the training phrases like for instance the first one DX0808 it does work...
How can I make this work without adding all the possible order id's ranging from DX0001 to DX9999 in the training phrases or the entity.
I mean it does work for my youtube query, I can put anything there it does "catch" the value. Any help please?
It looks like the required parameter is the problem here, my suggestion would be to:
Create intent to get the order id in one sentence without reprompt (turn off required on the order id) and id is always present, ex: "my id is DX0402". Include training response where only ID is provided like "DL3932", ex. below:
Set other intent for scenario when customer wants to provide the id but it is missing, for ex. customer says: "my id" and make your bot ask for the id as an response ex. "ok, provide me your id"
If you do it, in case user doesn't provide the id, intent 2 will be triggered and after id is provided you'll trigger intent 1.
Hope this makes sense.
I am making a bot for booking rooms. For booking rooms a user can choose "Premium Service" or "Standard Service".
However the hotels available to be booked depends on "Premium" or "Standard".
How to do this in dialog flow?
I tried to set entities "Service_type" and "Hotels". However how to set values for entity "Hotels" based on "Service_type" the user has selected?
Please note that the intent of the bot is book rooms. And there are many other steps to be followed to complete it.
You can start by creating an entity like quality and it's helpful to think of other ways that the user might refer to the quality that you define as "standard" and "premium"
Now when you create your intents you should see that Dialogflow automatically detects your entity in the training phrases
If Dialogflow doesn't already detect your entity, you can highlight a word in the training phrase and associate it to a type of your choosing
That's the easy part.
In order to present a different set of hotels depending on which standard that was selected, you should look into developing a fulfillment endpoint that handles the logic.
The quality choice that the user made in the first question will be passed as a parameter and you can easily make conditional logic to select hotels depending on that
conv.ask(`Here is a list of ${quality} hotel options for you`);
if (quality === "premium") {
conv.ask(getPremiumHotelOptions()); // Carousel or list
} else {
conv.ask(getStandardHotelOptions()); // Carousel or list
}
You can create an empty Hotels entity and then populate it with the relevant entity values for that session in your fulfillment webhook.
If you're using node.js for your webhook, you can look into the Dialogflow library to do much of this work. The call might look something like this:
const sessionEntityTypeRequest = {
parent: sessionPath,
sessionEntityType: {
name: sessionEntityTypePath,
entityOverrideMode: entityOverrideMode,
entities: entities,
},
};
const [response] = await sessionEntityTypesClient.createSessionEntityType(
sessionEntityTypeRequest
);
(See a more complete example at https://github.com/googleapis/nodejs-dialogflow/blob/master/samples/resource.js in the createSessionEntityType() function)
I am trying to build a bot(custom UI in my website) where a user will enter a product name to view the details of it and I will provide a link to the product full details page. I have a situation where if the user enters a name and there are multiple results from my database, I want to show him those products as quick replies so that he can select one from them.
How do I recognize that the user has entered the product name and anything else? I can use #sys.any, but all small conversation will also go there, which will be of no use.
The same problem occurs when I display him a list of products with matching name. But now when the user clicks on any of the button I am taking him to a custom follow-up intent where I have entered the template for a product entity. But, dialogflow only recognizes the products that have been defined in the entity(listed few products and checked auto expand).
I have tried using #sys.any instead, but the intent is called for any string the user types in. Lets say, the user does not respond and after a while he types in "hi", my intent with any is being called. How do I overcome this situation?
So far as I understand, I can see two ways to solve this query. First, using an entity & defining your product list over there for bot to understand user responses (which you have done) but this will become an overhead when you have a list of say 1000/more products. Second way, you can continue using #sys.any & define a parameter, write a webhook where you validate user entered response to product list in database & check if it is present over there, if yes, show product details or say, entered response is incorrect.
