RE: Is there any tool that generates pattern based on the key words

You can use response lists for keyword responses.

Question
Response
keywords: keyword1 keyword2

For an AIML or Self pattern that evaluates keywords you can use a simple wildcard pattern,

In Self,

Pattern("^ [keyword1 keyword2] ^")

In AIML,

<pattern>^ [keyword1 keyword2] ^</pattern>
