Syntax analysis is still an area of active research in linguistics. The language used is often lisp, but Perl is probably also a reasonable choice. Your problem is slightly easier than the corresponding 'grand challenge' problem, which is understanding natural language. In general, it is easier to transmit than to receive.

Tree data structures often used in natural language. Chapter 8 of Mastering Algorithms in Perl is about tree data structures, which are handled by the graph modules.

It looks like there is an AI dictionary that could be helpful in creating a useful syntax tree. You might be able to design a data structure that works like a subset of this dictionary.

Look at Damian Conway's wonderful Coy module, which is a haiku generator which is designed to create human-friendly messages. Although you aren't trying to generate haiku, you may be able to use similar programming techniques.

I think it is justified to attempt to solve such large, open problems, even if the chance of a breakthrough is small. It is a great learning experience, and you just might make a real contribution. You can also think about potential technology advances to look for in the future, so that you might be the first person to apply a newly-available technique to a difficult problem.

It should work perfectly the first time! - toma

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
