Threshold Estimation

Currently it is possible to perform threshold estimation tasks using the kth_threshold tool. The tool computes the k-highest impact score for each term of a query. Clearly, the top-k threshold of a query can be lower-bounded by the maximum of the k-th highest impact scores of the query terms.

In addition to the k-th highest score for each individual term, it is possible to use the k-th highest score for certain pairs and triples of terms.

To perform threshold estimation use the kth_threshold command.
