Representation and computation of units of translation for machine interpretation of spoken texts
Ch. Boitet · 1989
In the spirit of the blackboard technique, the paper proposes to use a layered weighted lattice as the coarsest representation of a unit of translation. Weights on nodes or arcs may be thought of as scores or activation/inhibition factors. At each layer, nodes corresponding to the same input fragment are clustered, and the ones sharing the same class are packed, thus allowing factorized treatment of ambiguities
