<br />
Start for a new work: Detecting key entity in a query.<br />
<br />
(e.g. In query "pickup for guitar", the key entity is "pickup".)<br />
<br />
Plan: (1)Use web search co-click data to obtain training data, use query pair to determine key entity.<br />
<br />
(2)for each query, extract the following information: stemmed word, POS, entity, modifier and so on.<br />
<br />
(3)Use CRF model to learn from training data, using features that are extracted in step (2); finally predict key entity in unseen queries.</div>Xiezd
