Lost in time and space...

Having done the word to number conversion, the next target is to write a series of blogs on how to handle expressions expressed in English sentence -

Part I - lets make a simple expression parser, one which can understand expression with constant numbers. Like "hundred and fifty plus five hundred".

Part II - We'll extend the simple parser to handle symbols. Example - "John has hundred and fifty doller" or "John has twice of what Jimmy has.". We'll talk about generating expression forest & symbol tables.

Part III - Solving. Well, we'll put in a agent based design that would
a. traverse through the expression forest
b. recognize patterns & try to map them to the domain they work against (ex. linear equation could be domain of "Linear Solver" agent)
c. Agents solve part of the unknowns. We'll also define a controller that "talks" to different agents to solve all unknowns (unless its not possible to solve for all)

So watch out ...
