As transducers translate a
string into another string
,
the morphological analysis and generation of inflected forms is
straightforward - it consists of following labels from one level in a
dictionary-transducer. As the generation is an inversion of the
analysis, i.e. we follow the output labels instead of input labels, we
will include only the analysis.
Figure 6.4: Morphological analysis with transducers
The dot operator in fig. 6.4 represents
concatenation. The result of concatenating a string with an empty
string is the same string, i.e. 
. The use of
the empty string in transition labels is necessary as the lengths of
the strings may not match. It is also useful for the alignment of
segments of strings that represent the same features. Such alignment
may reduce the size of the transducer.
