2018-11-1 · Finite-state transducers introduce progressively markings and labels within the input text. Transducers are arranged in cascades (or layers) where the subsequent transducer takes the output of the previous one as input. After a certain number of cascades the initial input (which is a tagged sentence) is transformed into a structured text

### Lecture 15 Finite State TransducersUMass Amherst

2004-11-22 · finite state transducer is a finite state automaton in which the members of Σ (the symbols labeling the arcs) are pairs triples etc. rather than simple symbols. Traditionally the members of Σ in a transducer are just pairs of which the left-hand member is the `input symbol and the right-hand member is the `output symbol .
