A method extracts all "short" ambiguity from an input FST (i.e., ambiguities of one arc in length). The method factors the input FST into a first factor and a second factor such that the second factor contains all ambiguity that is one arc long, and the first factor contains all other parts of the input FST. The method a priori prevents the creation of some redundant intermediate symbols.
