1. A system comprising: a non-transitory memory storing machine-readable instructions for: a text classifier, a datafield classifier, a metadata classifier, a combination classifier, and a feedback controller; and a processor communicatively coupled to the memory, the processor executing the machine-readable instructions to: identify, according to a log format rule, a log description of a log entry and a metafield of the log entry, the identification performed using the text classifier; store, in a repository, a plurality of datafield indicators previously prioritized according to a number of times that each of the plurality of datafield indicators were previously recalled; determine that the log description comprises a datafield based on a comparison of the log description with datafield indicators that are associated with respective priority values greater than a threshold priority value, the determining performed using the text classifier; generate datafield metrics for the datafield, the datafield metrics corresponding to categorical identifiers, the datafield metrics indicating an accuracy of a datafield categorization, the datafield categorization including an association between the datafield and a corresponding categorical identifier, and the generating performed using the datafield classifier; generate metadata metrics for the metafield, the metadata metrics corresponding to the categorical identifiers, the metadata metrics indicating an accuracy of a metafield categorization, the metafield categorization including an association between the metafield and the corresponding categorical identifier, and the generating performed using the metadata classifier; apply weight values to the datafield metrics and the metadata metrics, the applying performed using the combination classifier; generate weighted metrics for the log entry, the weighted metrics including an accuracy indication of a log categorization, the log categorization including an association between the log entry and the corresponding categorical identifier, the generating performed using the combination classifier; generate a mapping between the corresponding categorical identifier and to the log entry in response to at least one of the weighted metrics for the log entry exceeding a predefined threshold, the mapping performed using the combination classifier; and remove, in the repository, the datafield indicator from the datafield indicators in response to a feedback input indicative of the mapping being incorrect, the removal performed using the feedback controller.
