Check 2 values in aiml file

Question

How can I check 2 values in condition or with other tags? I want check if the user's name is equal with Unknown user value but I don't know how can I do this.

Answer 1

Assume you have the user name stored in a global property (predicate) called user, using <set name="user">George</set> You can check the user's name with an AIML category like this:

<category>
  <pattern>WHAT IS MY NAME</pattern>
  <template>
    <condition>
      <li name="user" value="unknown">You haven't told me your name</li>
      <li name="user" value="">You haven't told me your name</li>
      <li>Hello <get name="user"/>!</li>
    </condition>
  </template>
<category>

This works as follows:

1. You set up a category that responds to user input "What is my name"
2. The <li> elements in the <condition> test the name property for unknown and blank. In this case the AI replies the user hasn't told us their name.
3. The final <li> element is triggered if we have a name, and it replies with 'Hello' followed by the user name.

I haven't tested this with program O but it's standard AIML and should work fine. I have successfully coded similar categories in my own AI.
