Finding related keywords


Job Description

I'm looking for someone with Python experience to help me build a library for finding terms related to a given term. does a great job of this. For example, see their list of related terms for "italian sculpture":

I realize this may best be built by using some other service's API, which is fine, if we can identify a good one that is open for commercial usage.

Otherwise if it's mostly a custom build using NLTK that's good too.
