This paper presents a tree-to-tree transduction method for sentence compression. Our model is based on synchronous tree substitution grammar, a formalism that allows local distortion of the tree topology and can thus naturally capture structural mismatches. We describe an algorithm for decoding in this framework and show how the model can be trained discriminatively within a large margin framew...

Synthetic transducers transport externally added metal ion cofactors across the lipid bilayer membrane of vesicles to trigger catalysis ester hydrolysis in inner compartment. Signal transduction activity is modulated by hydrazone formation.

Abstract To move between different semiotic systems , such as graphs and formulas, is a necessary step in learning physics or solving problems. In s ocial semiotics this movement of material called transduction during student must unpack filter highlight aspects the concept problem. Unpacking, filtering, highlighting have been shown to be important meaning-making process transductions should se...
