Eliza is an early
natural language processing
program that was created by Joseph Weizenbaum
at MIT in the 1960s. In this journey into software engineering, we’ll attempt to create a
faithful replica of the original Eliza from scratch, armed with nothing more than
Weizenbaum’s original paper
as a guide. Along the way, we’ll learn some important concepts about software engineering.
Each step of this journey consists of a starter C# program that you expand by adding code to it,
and a finished solution. (In reality, each step’s starter program is nothing but the previous
step’s solution.) You should wait until you’ve finished fleshing out the starter app
before peeking at the solution. But do take a look at the finished solution and
compare it to the app you wrote.
