MOTIVATION
- Identifying queries that make it difficult for
search engines to find relevant documents
enables alternative processing strategies
- Query difficulty has been predicted for
ad-hoc tasks based on ambiguity using
clarity metrics
- How can we predict query difficulty in a
precision-oriented web search task?
