92. The system of claim 90 , wherein generating likelihood assessments for possible values further comprises generating a likelihood assessment for a possible value, the likelihood assessment being proportional to a degree of match between a first ordered set and a second ordered set, the first ordered set corresponding to a portion of the stored order information for the possible value, and the second ordered set corresponding to the possible value plus values entered in the current form instance before the current form field object; and the operations further comprising, before predicting a value for the current form field object: adjusting the generated likelihood assessments based on a determined characteristic of the current form field object, and adjusting the generated likelihood assessments based on a determined characteristic of the possible values.
90. A system comprising: one or more processors; and one or more storage devices storing instructions that when executed cause the one or more processors to perform operations comprising: storing order information for values observed in form field objects; generating likelihood assessments for possible values to be entered in a current form field object based on a comparison of order information for values entered in a current form instance with the stored order information for the observed values, the likelihood assessments indicating relative probability of the possible values being entered in the current form field object; and providing the generated likelihood assessments and the possible values for use in predicting a value for the current form field object.
