Our initial motivation for measuring ranking robustness is to predict topic difficulty for content-based queries in the ad-hoc retrieval task. ...
Though our focus is on prediction under the ad-hoc retrieval task, we observe an interesting negative correlation with query performance when our technique is applied to named-page finding queries which ...
Generally speaking, current prediction methods extract features of retrieval and compute the performance score for each query by using the features to estimate the query performance. ...

In this work, we investigate the causes for inefficient queries, identifying reasons such as the balance between informativeness of query terms, and the distribution of retrieval scores within the posting ...
Dynamic pruning strategies are effective yet permit efficient retrieval by pruning -i.e. not fully scoring all postings of all documents matching a given query. ...
In contrast, most post-retrieval predictors require the scores or contents of retrieved documents (e.g. to estimate a language model) or passes over the posting lists to estimate the number of documents ...
