62. The system of claim 54 , wherein the form presentation component displays the one or more predicted values in the one or more current form field objects and dynamically redisplays new one or more predicted values in response to user input to the current form instance.
54. A system comprising one or more processors: an input/output system; an auto-fill engine providing proposed values and corresponding likelihood assessments generated based on values entered in observed form fields using the input/output system, the likelihood assessments indicating relative probability of the proposed values being entered in one or more current form field objects in a current form instance; and a form presentation component displaying the current form instance using the input/output system such that one or more predicted values are displayed in connection with the one or more current form field objects, the one or more predicted values being selected from the proposed values based on the likelihood assessments, wherein the auto-fill engine provides the proposed values and the corresponding likelihood assessments based on a determination of semantic similarity among the one or more current form field objects and the observed form fields.
