This paper describes a novel strategy for automatic induction of a monolingual de- pendency grammar under the guidance of bilingually-projected dependency. By moderately leveraging the dependency in- formation projected from the parsed coun- terpart language, and simultaneously min- ing the underlying syntactic structure of the language considered, it effectively in- tegrates the advantages of bilingual pro- jection and unsupervised induction, so as to induce a monolingual grammar much better than previous models only using bilingual projection or unsupervised in- duction. We induced dependency gram- mar for five different languages under the guidance of dependency information pro- jected from the parsed English translation, experiments show that the bilingually- guided method achieves a s...
