Abstract
A method and system for autocompletion of multiple fields in electronic forms that generates “inference networks” (Bayesian networks), and evaluates them to suggest likely options for user selection while filling out fields in corresponding electronic forms. The disclosed Bayesian networks are generated and evaluated based on a broad set of information. The information used by the disclosed system for generating an inference network includes form previously selected field values. The information used in the disclosed system to evaluate an inference networks while a current instance of a given form is being filled out includes values previously entered by a current user into preceding form fields, and values of ambient variables that are external to the forms, such as current day of the week, current time of day, etc. When the inference network is evaluated in this way, posterior probabilities are determined for values of fields not yet filled out in the current form instance. These posterior probabilities are used to present value options for the unfilled fields in a way that makes selection of the most-probable options convenient to the user.
