Keywords dictionary

I developed a web site to search a database of videos indexed by keywords. There are several keywords that are repeated like "kid" and "kids" or "children"

I'd like that when users search for a keyword they will fi开发者_C百科nd also videos with similar keywords and keywords translation (ex. "kid" > "kinder").

I was thinking about using an external dictionary, there's Google dictionary but it does not provide APIs.

Have you got any idea on how can I do that?

Thanks

Giuseppe
