Usage <learnf>-tag and getting only username
  
 
Posted: Nov 28, 2017

Hello!

I’ve a few questions about AIML 2.0:

1. The <learnf> tag:

I tried to use the tag this way, but it doesn’t work:

<category>
      <pattern>I AM * YEARS OLD</pattern>
      <template>You are <learnf><set name="age"><star/></set></learnf> years old.</template>
</category> 

HUMAN: I am 20 years old.
BOT: You are years old.

The first problem: Where is the “20” in “You are years old.”? And the second problem: The <learnf> creates the “pand_learn.aiml” automatically. But this file is empty (apart from the <aiml> tag)!


Can you help me to use the <learnf> tag correctly (a simple example would be great!)

2. only name input
I don’t know whether this is really a problem, but I don’t know how to solve it. How can I create a pattern that accepts only the name of the human?

...like this way:
BOT: What’s your name?
HUMAN: Otto.
BOT: Hello Otto.

At the moment I have to write it this way:
BOT: What’s your name?
HUMAN: My name is Otto.
BOT: Hello Otto.

<pattern>My name is *</pattern>
<template>Hello <star/>.</template> 

Only the name would mean something like this:

<pattern>*</pattern>
<template>Hello <star/>.</template> 

But this can’t be right, because every word would match with this pattern. I’m a bit confused. Can you help me? red face

First of all, I’d like to state I’m using Program AB. If you’re using Pandorabots, this might not necessarily work.
The main error here is that the <learnf> tag is meant to be wrapped around the entire category you wish to create. In turn, the <learnf> category is wrapped around a <template> tag.
In your case, we’d like:

<category>
      <pattern>I AM * YEARS OLD</pattern>
      <template>
            <learnf>
                  <category>
                        <pattern>HOW OLD AM I</pattern>
                        <template>You are <eval><star index="1"/></eval> years old.</template>
                  </category>
            </learnf>
      </template>
</category> 

Notice the <eval> tag is used to ‘run’ something before we create the new category.
However, I think the solution you’re really looking for uses a <learn> tag since <learnf> makes the changes global - everyone will have your age until they too change it.

Perhaps the best solution is the following:

<category>
      <pattern>I AM * YEARS OLD</pattern>
      <template>You are <set name="age"><star/></set> years old.</template>
</category>

<category>
      <pattern>HOW OLD AM I</pattern>
      <template><condition name="age"><li value="unknown">You have not told me your age.</li><li>You are <get name="age"/> years old.</li></condition></template>
</category> 

You’re next point is quite easy to solve.

<!-- this is just an example category -->
<category>
 <pattern>WHAT WOULD YOU LIKE TO ASK ME</pattern>
 <template>What is your name?</template>
</category>

<category>
 <pattern>*</pattern>
 <that>WHAT IS YOUR NAME</that>
 <template>Hello <star/></template>
</category> 

You might also want to wrap the <star> tag in a <set> tag as you did in the age example. Then you can store it and use it later.

Thanks for the question and good luck,
Mush.

Thanks, Mush! You helped me so much. red face
I am using Program AB too. So your solution works.

But I have another question concerning the <that>-tag. smile
With your help I could write something like this:

<category>
      <pattern>WHAT WOULD YOU LIKE TO ASK ME</pattern>
      <template>What is your name?</template>
  </category>


  <category>
      <pattern>*</pattern>
        <that>WHAT IS YOUR NAME</that>
        <template>Hello <set name="username"><star/></set>! How old are you?
            <learnf>
                <category>
                    <pattern>WHAT IS MY NAME</pattern>
                    <template>YOUR NAME IS <eval><star index="1"/></eval></template>
                </category>
            </learnf>
        </template>
   </category> 

The next problem is: How can I connect this template…

Hello <set name="username"><star/></set>! How old are you? 

...with another category using the <that>-tag? I don’t know how to write this template with <set> and <star> into the <that>-tag. Is it possible?

My idea was something like

<that>HELLO<star/> HOW OLD ARE YOU</that> 

..because I know that something like…

<srai>MY NAME IS <star/></srai> 

...works inside <srai>, but my idea doesn’t work because of the <star>-tag inside the <that>-tag.

Best regards
Otto

Dear Otto,
There are two or three I think you could achieve this.
The first approach is to create the category in the <learnf> tag. We simply use <eval> like before!

<aiml>
 <category>
  <pattern>WHAT WOULD YOU LIKE TO ASK ME</pattern>
  <template>What is your name?</template>
 </category>

 <category>
  <pattern>*</pattern>
  <that>WHAT IS YOUR NAME</that>
  <template>Hello <set name="username"><star/></set>! How old are you?
   <learnf>
    <category>
     <pattern>WHAT IS MY NAME</pattern>
     <template>YOUR NAME IS <eval><star index="1"/></eval></template>
    </category>

    <category>
     <pattern>*</pattern>
     <that>HELLO <eval><star index="1"/></eval> HOW OLD ARE YOU</that>
     <template><set name="age"><star index="1"/></set>? What a brilliant age!</template>
    </category>
   </learnf>
  </template>
 </category>
</aiml> 

Note: I would strongly recommend using the <learn> tag rather than <learnf>. <learnf> switches to using AIMLIF on my computer.

Another technique is using <that>* HOW OLD ARE YOU</that> instead of <that>HELLO <eval><star index=“1”></eval> HOW OLD ARE YOU</that>. It’s just a bit shorter.

There are a few other techniques but they just feature not using the <learn> tag at all!
Anyway, I hope that helps and thanks for the question,
Mush.

Thanks again. It’s easier than I expected grin
There is just one little mistake concerning <learnf> in your code. This would save the whole line:

<category><pattern>*</pattern><that>* HOW OLD ARE YOU</that><template><set name="age"><star index="1"/></set>? What a brilliant age!</template></category> 

I’ve tested these things with Pandorabots and Program AB. Connecting the templates with <that> and using <learnf> tag with <eval> is working with Pandorabots and Program AB.
Something like

<that>HELLO <eval><star index="1"/></eval> HOW OLD ARE YOU</that> 
or
<that>* HOW OLD ARE YOU</that> 

isn’t working with Pandorabots. The problem is the <star> tag. And the “*” just don’t work without any error message.
I don’t know whether it will work with Program AB. I will test it this evening and hope it will work.

Best regards,
Otto

I think it isn’t only a problem of the <star> tag or something like the “*”. It’s also a problem of connecting a template with two or more sentences with <that>, because something like

<that>HELLO OTTO HOW OLD ARE YOU</that> 

isn’t working, too - in Pandorabots.

A little Update: I’ve solved the problem (for Pandorabots and Program AB) and it was easier than I’ve expected. red face grin

If the bot’s last response consists of multiple sentences like…

<template>Hello <set name="username"><star/></set>! How old are you?</template> 

...the <that>-tag will only match the bot’s last sentence.

So…

<that>HOW OLD ARE YOU</that> 

...will match!

Best regards,
Otto

Hi All,

Can you please explain what is expected from user to enter so that interpretator understands that this text should be added in learnf.aiml and if user ask same q again then its response correctly.

For example : apple color is not present in aiml files so user wants to add apple color.

thanks in advance

Hi,

I have just modified the external library making Program AB learnf tag work as the specification for AIML 2.0. You can refer my modification below.

@Giang Nguyen: Thank you! This is really great. But I’m a bit confused - I’ve used the ProgramAB.jar from https://code.google.com/archive/p/program-ab/.
How can I update this .jar with your modification? Or do you already have created a modified version of this .jar?

Oh, so sorry, I have received any notification. You should change the file src/main/java/org/alicebot/ab/AIMLProcessor.java, this file is in program-ab package, and the github has been changed to: https://gist.github.com/luulinh90s/73a884f74736c5aa2457a2feedc67f1f
