14. The system of claim 13 , wherein the processor is configured to combine first and second probabilities for each candidate, and include a candidate in the subset of one or more candidates if a ratio of the combined probability for the most probable candidate and the candidate in question is above a threshold value.
14. The system of claim 13 , wherein the processor is configured to combine first and second probabilities for each candidate, and include a candidate in the subset of one or more candidates if a ratio of the combined probability for the most probable candidate and the candidate in question is above a threshold value. 15. The system of claim 14 , wherein the processor is configured to determine a third probability for any candidate of the subset, wherein the third probability is determined by searching in the stored sequences for a sequence comprising a context sequence, and optionally valid orthographic and lexical variations thereof, in combination with the candidate, wherein the context sequence is user inputted text that precedes the input sequence and comprises one or more terms separated by one or more term boundaries.
