1. A method for browsing patient information, comprising the steps of: mining, by a processor, for patient information, the mining extracting values for respective variables as at least some of the patient information, each of the variables assigned one value, each of the values for each of the multiple variables being derived from multiple pieces extracted from a data source, each of the pieces referring to a same variable being assigned first probabilities indicating likelihoods of the respective variables being the corresponding values, at least one of the first probabilities being less than 100%, each of the values determined with a unified probability determined by combination of the first probabilities from multiple of the pieces referring to the same variable such that the multiple variables are assigned respective values and respective unified probabilities, the pieces and values representing a patient at a particular time; selecting at least one of the variables to view the patient information related to the selected one of the variables, the selected patient information related to the selected one of the variables including a subset portion of the data source, the subset portion including the piece extracted for the value of the selected one of the variables and additional information associated with the piece from the data source and not including other information from the data source for the patient, the piece included in the subset portion associated with the first probability used to determine the unified probability of the value for the selected one of the variables; presenting the selected patient information on a screen.
