Báo cáo khoa học: "Efficient Inference Through Cascades of Weighted Tree Transducers" ppt

... Application of tree transducers Now let us revisit these strategies in the setting of trees and tree transducers. Imagine we have a tree or set of trees as input that can be represented as a weighted ... (Mohri, 1997). Less well-studied but of more recent in- terest is application of cascades of weighted tree transducers (WTTs). We tackle application of WTT cascad...

... linear-chain), an exact inference can be obtained efficiently if the num- ber of output labels is not large. However, for large number of output labels, the inference is often pro- hibitively expensive. To ...

... as reachability in the tree. Domi- nance graphs are used as underspecified descriptions by describing sets of trees that are encodings of the formulas of some language of semantic representa- tions, ... graphs are directed graphs with two kinds of edges, tree edges and dom- inance edges. They can be used to describe the set of all trees into which their tree edges can be embed...
