Predictive conversion of user input

Systems and methods for predictive conversion of user text input in one language or character set to another language or character set are disclosed. The method may generally include converting a partial user input in a non-target language or character set to a converted partial user input in a target language or character set and computing likely possible converted completions of the converted partial user input based on a likely completions module. The converting may be based on a dictionary of non-target language or character set to target language or character set mappings. The likely completions module may be a database or a model trained by performing statistical analysis on a database of user inputs or a subset thereof. The subset of user inputs may be selected from those from a particular geographic location or time period and/or from the user or the user's current session.
