Various questions regarding PowerLoom

Hello,

is PowerLoom the appropriate language to program question-answer expert systems?


For instance,

"Please input the client's honorific" 

Mr
Mrs
Ms

> Mr

"Please input the client's name" 

Paul Johnson

"Please input the client's age" 

> 45

"Please enter the client's occupational status"

unemployed
student
employee
manager

> employee

"Please input his country" 

> GB

"Please select the client's subscription period" 

6-month
12-month
24-month

> 12-month

[Searching the best deal for Mr. Paul Johnson and for the newspaper]

"You should offer Mr. Paul Johnson who's 45, is an employee, and lives in GB, a 12-month subscription at EUR 400".



How does it compare with other expert-system languages such as SOAR, ACT-R and Drools, for such purposes?

Many thanks.

Philippe
