We had a developer to come up with a prototype for a bot for bookkeeping questions and we understand that the bot is not perfect. Our biggest challenge was to ensure that after 2-3 failed attempts for the bot to receive an appropriate response, the bot moves on to the next question and that's it. Our previous developer claimed that it's not possible, is that true or not? Currently the bot just gives up after a couple of attempt and that's it.
I am not a tech person and I would really appreciate some help on this.
Hypothetical example of the ideal scenario:
Q: What accounting software do you use?
A: askdnjsajld
Q: Didn't get that. What accounting software do you use?
A: asdkjnajksdn
Q: I am sorry, didn't get that. Let's move on to the next question... When would you like to receive your financials?
A: month-end
Thank you for your help!
Yes, this is possible, although the exact details of how you do this depend on how you're handling responses from the user in the first place.
The most important thing to keep in mind to handle this, however, is to remember that Intents represent what the user says and not how you handle it or how you reply.
That last bit gives the simplest answer to your question - you can, of course, reply however you want the bot to reply after each round. It sounds like you were able to implement logic that says if it got a result it didn't want - you can extend that to add a counter that just uses the next question as its reply after a number of tries.
The more difficult part is to make sure that you know what question the user is replying to, and to make sure you capture the right value in case they try to go back and answer a previous question.
The general solution to this problem is twofold:
Have one Intent that accepts the direct answer to the question you're currently on, but have it triggerable only with certain Input Contexts being set. Then set that Context to be valid when you ask the question, and remove the Context when the question is answered.
Have other Intents that specifically respond to how the user might phrase the question if they were going back to answer it.
For example, if you have asked "What software do you use?" you might set the Context "ask-software-used". You would then have two Intents:
One with an Input Context of "ask-software-used" that accepts just valid software names.
Another with no Input Context, but which might have training phrases such as
"I'm using XXXX software"
"We are working with the XXXX package"
once the user does answer the question, clear the "ask-software-used" Context, ask the next question, and set its Context.
You can also use this to keep track of how many times you've had to repeat the question, waiting for an answer. If that counter hits the limit, do the same thing: clear the Context, ask the next question, and set its Context.
I want to ask the users a few questions in my welcome intent and depending on their answers give them a particular output.
My problem is that, once the user answers the first question, the agent exits my welcome intent and tries to match with the next intent.
I thought I could solve this by matching it back to the welcome intent.
So ideally it should have gone like this :
Welcome intent -> 1st question -> user answer -> Welcome intent ->2nd question -> and so on
But actually this happens :
Welcome intent -> 1st question -> user answer ->Welcome intent -> 1st question
It will keep asking the first question.
To solve this , I started maintaining a flag for each question.
If question 1 was answered I would set its flag true and then use it to skip the first question when the welcome intent is matched for the second time.
This is a very convoluted way to do it and probably far from the best way to do it.
Can anyone point me in the right direction to implement it?
Thank you.
Edit : I have given up my old method. Let me explain what I want to do and then I can get guidance on the way I should implement it.
I have 16 different outputs and I would like to show one of them to the user depending on their answer to 4 questions. Each question will only have two answers as options and depending on the option chosen by the user for each question , I will pick one of the 16 outputs and display it to the user.
How do I accomplish this using diaglogflow node.js?
First of all remember that an Intent captures what the user says or does and not what you do with that information or how you reply to it. That part is best handled by your fulfillment. While we can use Contexts to limit which Intents will be considered for a user response they are probably most useful in this case to store your state and keep track of which questions have been asked and answered.
Under this scheme, your Intents remain responsible for capturing input and your fulfillment examines this input, changes state based on this input, and sends a reply based on the new state (what it needs to ask next). If the user's responses will be mostly the same (free form, or from the same set of phrases), you can even use the same Intent to capture this input and the fulfillment would use the state and input to determine what logic to execute. If you need different types of input, and thus different Intents, their handlers can still call common functions to do the processing and change the state/reply.
This is further discussed in Thinking for Code: Design conversations not logic
You can use the concept of the follow-up intents in Dialogflow Console to create a chain of questions/answers.
Here is an example of my chain of questions/answers:
Though I still strongly advise you to study also how input/output context works. Especially if you want to collect all user reply parameters in the one final fulfillment of the last step to avoid storing the user inputs in fulfillments attached to every intent of the chain.
I’m working on a memory game with multiple levels on Dialogflow. Each correctly guessed question is a separate intent and all 3 questions need to be answered correctly to proceed to the next level. How do I create the game so that the second level (which will be the follow up intent) is only provoked when all 3 questions from the 1st level are answered correctly? Thank you in advance!
Instead of having the followup intent, you can maintain a counter in a parameter (see my answer here for storing parameters).
Enable webhook in all the intents.
Whenever a question is answered, check the validity and if correct increment the counter.
When the counter reaches 3, you can respond back with the response of your choice.
If you want to go by your way then, after answering 3 question correctly you will need to generate an event dynamically via webhook. And the fourth intent should be triggered using that event.
I am trying to jump to a random question with followup event, and at the same time store the question number in the context. But dialogflow only jumps to the event without storing the question number. Is there a way to do followup event and store a context in one intent?
app.intent('Quiz - random', (conv) => {
let rand = Math.floor(Math.random() * quiz_len) + 1;
conv.data.current_qns = rand;
conv.followup(`quiz-question${rand}`);
});
Not really. The point of using conv.followup() is to make it as if the new Intent is the one that was actually triggered by the user. Remember - Intents represent what the user is saying not what you're replying with. You can include a parameter with the redirect, which I guess you can use to send the question, but this still would be the equivalent of a parameter sent by the user.
It isn't entirely clear why you feel you need to direct to a different Intent. Is it just to ask the question as part of the reply? Go ahead and ask it in the Intent handler you're in and store the number in the context directly.
Update
You've indicated in the comments that you want to structure things so you have a "random dispatcher" that then redirects to an Intent to ask a question, and that Intent has a Followup Intent that accepts the right answer (and possibly ones that deal with wrong answers).
This requires you to build a lot of extra Intents for all the various questions, and then the conditions on each question. This requires you to re-build this structure every time you want to add a new question.
Dialogflow works very well to navigate the structure of a conversation - so you don't need to use it to navigate specific questions, answers, and responses. Remember - Intents model what a user says in broad terms, not how our agent responds.
Here is a structure that might work better:
There is an Intent that handles the user asking for a random question. The Intent fulfillment for this (ie - the handler function in your webhook) does the following:
Selects a question
Sets a context to indicate which question is being asked
Sends the context and the question to the user
There is another Intent that handles user responses. All user responses. If this is a multiple choice question, you can set very specific phrases, but otherwise you may need to make this a Fallback Intent that has the context specified above as an Input Context.
Your handler for this compares the answer.
If correct, you clear the context, say so, and ask if they want another question. (Which would then loop to the Intent specified in step 1.)
If incorrect, you make sure the context is still valid and tell them they're wrong. Possibly increase a counter so you don't let them guess indefinitely.
This means you're only building two Intents that handle the question itself. You should add a few more. Here are a few to think about:
What happens if the user doesn't say anything at all? The "No Input" scenario should be handled differently than a bad answer.
If you're asking a multiple choice question, perhaps you'll use a list and need to handle a list response.
Finally, if you're using a list, you may want to do something fancy and use Dialogflow's API to set a Session Entity Type for just that question. This allows you to set what you're expecting (with some aliases) for what is correct and incorrect, and then use a Fallback Intent for the context to say that what the user said didn't make sense.
What I can think of is pre-populating certain form input elements based on the user's geographical information.
What are other ways can you think of to speed up user input on long application forms?
Or at least keep them focus on completing the application form?
If you have a long form, try to prune it down. Don't ask them to fill in fields that you don't really need.
If the form spans several pages, give the user some feedback as to how many more pages there are. We users hate clicking on the continue button wondering if this will be the last page.
Never lose a field that they filled in, no matter what they do. This could have security implications if passwords are involved.
Use dropdowns to provide the user with options unless there are a lot of options that the user would have to scroll through or if the terms in the dropdown aren't widely accepted (e.g. dropdown filled with Systems Engineer, Solution Developer, IT Application... I just want Programmer.).
Provide help for fields that might be hard to fill in (or provide examples).
If it is possible in your case, just collect the bare minimum up front and then allow the user to use the basic features of your service.
For the user to upgrade to a better level of service, they will need to fill in the 2nd form with more detail.
How important it is to you to collect ALL that information up front ? It is worth losing customers by demanding too much from them ? Why not demand it later at a time more convenient to the user.
Creating a multi-step wizard offering only a small number of input fields per step. Ensure that they are aware of how far they have progressed in the sequence.
The psychology is that once a user is 'invested' in a task, they are more likely to continue. If you present the whole list of input fields at once, you scare them off.
Offering musings at each step (cartoon, humor, sayings etc) makes them move to the next step out of curiosity.
Users won't mind filling in long forms if and only if they feel that the questions that you ask are important: otherwise they will be discouraged, and become impatient with it.
Remember, in a web application people have very, very short attention spans. When the user starts feeling that you are asking too much, they're usually right.
Keep required information as few as possible: other info should only be optional, and you have to give something in return to the user to compel them to complete that information.
However you implement it, please please please use some kind of Ajax hearbeat to store their progress server side and repopulate it if it's lost. There is nothing more infuriating to a user that working through a long form and having a browser or network hiccup lose their entire submission.
Whenever it happens to me I generally never give it a second shot, because at that point recreating my submission isn't worth whatever I was signing up for.
Checklist:
Explain clearly the purpose of the form. (What's in it for them?)
Prune, prune, prune, and keep questions clearly relevant!
Give the user feedback on his/her progress (if the form is split over multiple pages)
Ask for as little as you can up-front and leave the rest for later.
Clearly mark required fields
Group fields logically.
Keep labels/headings brief and easy to understand.
Prefill as much as possible - but not too much.
Spread super long forms over multiple pages and allow backtracking.
Cleverly placed "Back", "Save" and "Cancel" buttons put people's minds at ease - even when redundant.
Provide friendly (but clear!) validation error messages, in a timely manner.
Allow the user to reclaim half-filled in forms - don't lose their data!
No matter what you do, do not include a reset button. :-)
Finally:
Explicitly tell the user when the process is finished. ("Thank you! Your application has been sent.")
Tell the user what will happen next. ("A confirmation e-mail has been sent to your e-mail address, and we'll process your application within two working days.")
use Ajax to populate and update the controls asynchronously.It will speedup the filling of long application forms.
Split it up into multiple pages - there's nothing quite so discouraging as seeing that you have another 100 questions to go.
Put validation on each input and check it onblur(). If they get to the end of the page and then it says "question #2 was incorrect", chances are they've forgotten what that one was anyway and it'll be more difficult to return to it. Plus, if they answer a series of similar inputs in a particular, incorrect way, you should let them know straight away (eg: entering dates as mm/dd/yyyy when you want dd/mm/yyy)
Split the form into several steps. It's like how someone is much more likely to read five 3-sentence paragraphs than one big 15-sentence paragraph of the same length.
I agree with tim; just let them fill in the bare minimum information and then leave the rest to profile updates. If any data is necessary for the service offered on your site, ask for it when they try to avail of the service (and no earlier).
That said, I wouldn't advocate the kind of forcing function that adam suggests. It pays to give your users the warm, fuzzy feeling that they are privileged and can use ALL of the services on your site. Although, if you look at it hard enough, adam's and my suggestions are pretty much the same.
If the application needs to include a lot of information, then make sure the user can save at any point, and log off, and log in later to complete the form. This would make more sense if some of the information is not necessarily easily available. Tax returns are an obvious example, where some of the data may need to be calculated, or the user must find the relevant documentation.
In some cases the user might use the same information in multiple applications. In that case it might make sense for the user to register their details (Name, Address, Telephone numbers, etc), which are automatically filled in on each application. For example, if you had a website for a recruitment agency, they may allow users to register their details, and then to apply for a particular job, they can just include a personal statement that applies to that job in particular.
As another consideration, if some information may be incorrect (particular if this is not always clear, such as a CAPTCHA, or a user name that must be unique), either separate it from the rest of the data, or otherwise make it so a mistake doesn't mean the rest of the information must be reentered.
These are basically ways of avoiding the user having to enter the same information twice.
