Hello, This post might be somewhat legally technical (although no legal knowledge i required to answer my question) and some 'advanced' search engine practices. Anyway: I'm currently writing a legal thesis on trade mark infringement of a proprietors trade mark as a keywords (in a advertising network such as AdSense) by a third party (who does not have any intellectual property rights ) over the trade mark. Anyway, with that (mouthful) said, I am trying to do some research on one specific contention which I will raise regarding n-gramming and fuzzy search matching. Do any advertising programs support either of these? If you do not understand either, unfortunately I cannot explain but it is important for my thesis to know if ANY (even a small ) search engine operates their (comparable) AdSense network by allowing n-gramming and fuzzy search matching. Take Google for example. If you search for "spicy", the AdSense sponsored listings would match and show only those advertisements which request "spicy" as a keyword. Google does not support (nor do I think it should) the above matching functions. However, one search engine might allow root derivatives of a word, such as "spicy" => "spic" or even "spice" Aditionally when n-gramming to different levels say three for example: spi pic icy ------ I do hope that someone knows a search engine would uses this for their advertising network, so if you know please advise!
If anyone could advise it would be very helpfu. I have looked over some others but I am so far of the conclusion that none exist. They all do "exact" matching.
