who says they're using POS tagging to perform the IR? I've only ever seen it used as a query refinement tool.
I agree, the bag of words / vector space model approach is (from what I've read) hard to beat, especially for a one-size-fits-all tool like google where you can assume nothing about the domain. (Unless they're switching approaches depending on the domain, which would be fascinating)
- syllogism 16y agoAs I'd define things, if you're using something for query refinement, then it's part of your IR system. How would you use POS tagging for query refinement though? You can hardly expect to POS tag the user's query, since it's unlikely to be a sentence. I suspect we have some miscommunication here.
