Web search intent induction via automatic query reformulation
Hal Daumé, Eric Brill · 2004
We present a computationally efficient method for automatic grouping of web search results based on reformulating the original query to alternative queries the user may have intended. The method requires no data other than query logs and the standard inverted indices used by most search engines. Our method outperforms standard web search in the task of enabling users to quickly find relevant documents for informational queries.
