Mahout and Third Party “Similarity” Services

by Amrinder Arora

Mahout is an extremely popular platform for recommendations these days. It is only a matter of time before people will start selling “similarity” services – give two SSNs and find the similarity between users – give two ISBNs and find similarity between books, give two SKUs and find similarity between products. Once such services are available, a facade to build on top of that is straightforward as well.

Consider a facade signature as:

double getSimilarity(String reference, String id1, String id2);

For example:
getSimilarity(“SSN”,”123-45-6789″,”123-45-6788″);
getSimilarity(“ISBN-13″,”978-1935182689″,”978-1617290183″)
