Query Classification for Solr - Howard Wan, Target
About 40% of our queries are ambiguous, which can result with products from many categories. For example, the query "red apple" can match the following products:
1. red apple ipod (electronic category)
2. red apple fruit ( fresh produce )
3. red apple iphone case ( accessories)
It is desirable to have a classifier to instruct Solr to boost items from the desired category. In addition, for a search engine with a small index, a good percentage of the queries may have little or no results. Is it possible to use the classifier to solve both problems?
This talk discusses a classifier built from behavior data which can dynamically re-classify the query to solve both problems.
