A server computing system determines a plurality of statistics for a plurality of test documents, determines a number of false negatives for a corpus of documents based on one or more of the plurality of statistics for the plurality of test documents. The classification of a document of the corpus of documents is a false negative if classification of the document by a classification model is negative and classification of the document by a user is positive. The server computing system calculates an effectiveness of an information retrieval system on a corpus of documents based on the number of false negatives for the corpus of documents.

Method and system for information retrieval effectiveness estimation in e-discovery

A predictive coding system updates a plurality of training documents for an untrained classification model based on a plurality of additional documents. The plurality of additional documents are selected from a plurality of unlabeled documents based on a decision hyperplane associated with a first trained classification model. The predictive coding system provides the updated plurality of training documents to the untrained classification model to cause the untrained classification model to be retrained and to cause a second trained classification model to be generated.

System and method for training data generation in predictive coding

A server computing system determines a plurality of statistics for a plurality of validation documents. The server computing system determines a plurality of statistics for a plurality of test documents. The number of test documents in the plurality of test documents is determined based on the plurality of statistics for the plurality of validation documents and the effectiveness measure of interest. The server computing system calculates an effectiveness of an information retrieval system on a corpus of documents based on the plurality of statistics for the plurality of test documents.
