nlp - Is there an algorithm that tells the semantic similarity of two phrases -

-

input: phrase 1, phrase 2

output: semantic similarity value (between 0 , 1), or probability these 2 phrases talking same thing

you might want check out paper:

sentence similarity based on semantic nets , corpus statistics (pdf)

i've implemented algorithm described. our context general (effectively 2 english sentences) , found approach taken slow , results, while promising, not enough (or without considerable, extra, effort).

you don't give lot of context can't recommend reading paper useful in understanding how tackle problem.

regards,

matt.
