Abstract
Documents may be evaluated to determine inclusion of one or more types of information, such as personal information. Within the documents containing the one or more types of information, individual spans of information may be replaced with alternative data, which may maintain a type of content associated with the spans. Datasets of documents may be created where one or more types of information have been removed. These datasets may also be evaluated to determine whether one or more elements are over or under represented and then the datasets may be modified, such as by adding or removing documents, to provide an improved balance or distribution of the one or more elements.
