The role of search queries, as available within query sessions or in isolation from one an- other, in examined in the context of ranking the class labels (e.g., brazilian cities, busi- ness centers, hilly sites) extracted from Web documents for various instances (e.g., rio de janeiro). The co-occurrence of a class la- bel and an instance, in the same query or within the same query session, is used to re- inforce the estimated relevance of the class la- bel for the instance. Experiments over eval- uation sets of instances associated with Web search queries illustrate the higher quality of the query-based, re-ranked class labels, rel- ative to ranking baselines using document- based counts.
