Where did you see the phrase used, in what context?

My first un-educated guess is that it has something to do with the way words are combined to form phrases.

Might be a good idea to ask google: what's the vector space model of query [google.com] ... ;)

h_b_k, didn't see your reply. However, now there's even a link to the query. ;)

Ok my first guess was a fair way off. I'm reading things well beyond my 1:45am brain :P

The model creates a space in which query is represented by m-dimensional vector, where m is the number of unique terms in the query and the length of m-th component of the vector is associated with the term frequency in the query. Then, a vector similarity function, such as the inner product, is used to compute the relevance between the query and a document in Goo index.
