[alicebot-style] difference between wildcards "_" and "*"

[Anne Kootstra]

There is indeed a difference between the two. Have a look at AIML.info's
FAQ. A direct link can be found here:

Take care,

Onderwerp: [alicebot-style] difference between wildcards "_" and "*"


hi,
i am wondering what the difference between the wildcards "_" and "*" is?
first, i thought that "_" would function as a prefix and "*" as a sufix. but
in the following example in category 3 it doesn't seem to have the function
of a sufix.
<category>
<pattern>MOTHER</pattern> <template> Tell me more about your family.
</template>
</category>
<category>
<pattern>_ MOTHER</pattern> <template><srai>MOTHER</srai></template>
</category>
<category>
                       <pattern>MOTHER _</pattern>       
                        template><srai>MOTHER</srai></template>
</category>
<category>
<pattern>_MOTHER *</pattern>
<template><srai>MOTHER</srai></template>
</category>
so, could you tell me where exactly the difference is and what role does it
play in the pattern matching algorithm?
thanks charlotte
