7. A system for recognizing handwriting, the system comprising: a digital pen configured to write pen strokes on a paper form and to store corresponding stroke coordinates associated with respective pen stroke locations on the paper form; and a processor configured to; associate a field on the paper form with a predetermined lexical inference type; determine that the stroke coordinates correspond to the field by: associating the field with an area on the paper form corresponding to a predetermined set of coordinates; and comparing the stroke coordinates to the predetermined coordinates to determine whether the pen strokes were written within the area associated with the field; based on the lexical inference type, dynamically update an inference lexicon associated with the field; and perform handwriting recognition on the pen strokes based on the dynamically updated inference lexicon.
11. The system of claim 7 , wherein the processor is further configured to associate the predetermined lexical inference type with a list of lexical inferences expected to be written in the field by the user.
