The symbolic reduction technique is used to simplify patterns. It helps to reduce complex grammatical patterns with simple pattern(s).
For example, consider the following conversation.
Human: Who was Albert Einstein?
Robot: Albert Einstein was a German physicist.
Human: Who was Isaac Newton?
Robot: Isaac Newton was a English physicist and mathematician.

Now What if questions are raised as
Human: DO YOU KNOW WHO Albert Einstein IS?
Human: DO YOU KNOW WHO Isaac Newton IS?

Here, <srai>  tag works. It can take the pattern of the user as a template.
<category>
   <pattern>WHO IS ALBERT EINSTEIN?</pattern>
   <template>Albert Einstein was a German physicist.</template>

Open the command prompt. Go to C > ab > and type the following command −
java -cp lib/Ab.jar Main bot = test action = chat trace = false

You will see the following output −
Human: Do you know who Albert Einstein is
Robot: Albert Einstein was a German physicist.

Divide and Conquer is used to reuse sub sentences in making a complete reply. It helps to reduce defining multiple categories.
For example, consider following conversation.
Human: Bye
Robot: GoodBye!
Human: Bye Alice!
Robot: GoodBye!
Now here robot is expected to reply GoodBye! Whenever a user says Bye in the beginning of the sentence.
Let's put <srai> tag to work here.
<category>
   <pattern>BYE</pattern>
   <template>Good Bye!</template>
</category>
<category>
   <pattern>BYE *</pattern>
   
   <template>
      <srai>BYE</srai>

Open the command prompt. Go to C > ab > and type the following command −
java -cp lib/Ab.jar Main bot = test action = chat trace = false

You will see the following output −
Human: Bye
Robot: GoodBye!
Human: Bye Alice!
Robot: GoodBye!

Synonyms are words with similar meanings. A bot should reply in the same manner for similar words.
For example, consider the following conversation.
Human: Factory
Robot: Development Center!
Human: Industry
Robot: Development Center!

Now here robot is expected to reply Development Center! whenever a user says Factory or Industry.
Let's put <srai> tag to work here.

Human: Industry
Robot: Development Center!

Using srai, we can return a simple response when the user types a specific keyword, say, School, no matter where "school" is present in the sentence.
For example, consider the following conversation.
Human: I love going to school daily.
Robot: School is an important institution in a child's life.
Human: I like my school.
Robot: School is an important institution in a child's life.

Here, the robot is expected to reply a standard message 'School is an important institution in a child's life.' whenever a user has school in the sentence.
Let's put <srai> tag to work here. We'll use wild-cards here.

   <pattern>SCHOOL</pattern>
   <template>School is an important institution in a child's life.</template>
