Hello all, This is more of a theory question then a RoR question, but perhaps there is some gem to help that I am unaware of. I am trying to aggregate store listings provided by 15 or so online shops, some of them provide the manufacturer''s SKU/MID information but some do not. When the SKU/MID is provided it is a simple matter to find the same items across multiple stores. However I have found myself with 5,000+ items just floating because they do not have a SKU/ MID. I am currently chugging through them to associate them with the same items from multiple stores. I am looking for a way to simplify this, right now I use the shpinx index to try to find similar items, but its hit or miss. Are there any algorithms I should look into that will help me identify items that are likely to be similar?
