Improve Recommendations

[Jahangir Mohammed <md...@gmail.com>]

I followed very much the example as given in the documentation and it's
working as expected so far.

Have a question on how I can use some of the metadata I have for users and
items to still improve the recommendations. It looks obvious how to do it,
but still want to get a heads up from people who have been using taste for
a while. So, is my assumption correct that I have to implement
UserSimilarity and ItemSimilarity interfaces?

Thanks in advance for any suggestions.

Thanks,
Jahangir.

You could make an ItemSimilarity based on the tags. Maybe you use the
Tanimoto coefficient to make a simple similarity metric based on their
presence or absence. Then you use an item-based recommender.

Thanks Sean for response. Let say, I have tags associated to the items
where items are more like an e-commerce(electronics, less than 20$, best
buy product,..so on) and I have some users demographic information. So, I
was thinking that I can write UserSimilarity and ItemSimilarity based on
these.

The best, or perhaps only, way to integrate such information is to
implement your own version of UserSimilarity or ItemSimilarity and
then use a user-based or item-based recommender. You can implement
whatever similarity rule you think is best according to your metadata.
There's not a lot to be said unless you can say more about exactly
what metadata you have.
