Query Understanding Enhanced by Hierarchical Parsing Structures
query understanding semantic tagging linguistic parsing
2016/1/23
Query understanding has been well studied in the areas of information retrieval and spoken language understanding(SLU). There are generally three layers of query understanding: domain classification, ...
Tree-based translation models, which ex-ploit the linguistic syntax of source lan-guage, usually separate decoding into two steps: parsing and translation. Although this separation makes tree-based de...

Non-Projective Parsing for Statistical Machine Translation
Non-Projective Parsing Statistical Machine Translation
2009/12/10
We describe a novel approach for syntaxbased statistical MT, which builds on a variant of tree adjoining grammar (TAG). Inspired by work in discriminative dependency parsing, the key idea in our appro...
We present the first unsupervised approach to the problem of learning a semantic parser, using Markov logic. Our USP system transforms dependency trees into quasi-logical forms, recursively induces la...
