16. The non-transitory computer readable medium of claim 15 , further comprising estimating an initial responsiveness score of the plurality of documents and the control set of documents are generated based on the initial responsiveness score.
15. A non-transitory computer readable medium, comprising instructions for: building a document map for a plurality of documents within a data store of a document system using a topic-related generative model for the plurality of documents; selecting a control set of documents from the plurality of documents, wherein the control set of documents is selected from a first strata of the plurality of documents and a second strata of the plurality of documents; sending the control set of documents to a user; receiving a control set metric regarding the control set of documents from the user, wherein the control set metric includes an indicator of responsiveness for each of the documents of the control set of documents; the document system performing the steps of: a) determining a responsiveness score for each of the plurality of documents based on a scoring algorithm; b) determining a set of responsive documents and a set of non-responsive documents of the plurality of documents based on the responsiveness score determined for each of the plurality of documents and a decision boundary score; c) determining a confidence score for the document system using the responsiveness score for each of the documents of the control set and the indicator of responsiveness for each of the control set documents received from the user; d) selecting one or more of the plurality of documents based on the responsiveness scores of the plurality of documents, wherein the responsiveness score of each of the one or more selected documents is at or near the decision boundary score; e) presenting the one or more selected documents to the user; f) receiving an indicator of responsiveness from the user for each of the selected documents; g) refining the scoring algorithm based on the indicator of responsiveness for each of the selected document; and h) generating a desired confidence score for the document system, and presenting the set of responsive documents to the user when the desired confidence score for the document system is achieved, wherein the confidence score for the document system is an F1 score determined by comparing the responsiveness score for the documents of the control set to the indicator of responsiveness for the documents of the control set received from the user.
