With the help of an example, explain the difference between forward chaining and backward chaining techniques used by an expert system
The following example helps to understand the differences between forward chaining and backward chaining techniques. In an expert system that provides financial investment advice for investors, the system might use forward chaining and ask 50 questions to determine which of five investment categories—oil-gas, bonds, common stocks, public utilities, and transportation—is more suitable for an investor. In addition, each investor is in a specific tax bracket, and each investment solution provides a different tax shelter. In forward chaining, the system evaluates all the "if-then-else" conditions before making the final recommendation. In backward chaining, the system might start with the public utilities category, specified by the investor, and go through all the "if" conditions to see whether this investor qualifies for this investment category.
