We introduce a novel Semantic-CategoryTree(SCT) model to present the semantic structure of a sentence for Chinese-English Machine Translation(MT).We use the SCT model to handle the reordering in a hierarchical structure in which one reordering is dependent on the others.Different from other reordering approaches,we handle the reordering at three levels:sentence level,chunk level,and word level.The chunk-level reordering is dependent on the sentence-level reordering,and the word-level reordering is dependent on the chunk-level reordering.In this paper,we formally describe the SCT model and discuss the translation strategy based on the SCT model.Further,we present an algorithm for analyzing the source language in SCT and transforming the source SCT into the target SCT.We apply the SCT model to a rule-based patent text MT to evaluate the ability of the SCT model.The experimental results show that SCT is efficient in handling the hierarchical reordering operation in MT.
