A Dictionary Lookup Strategy for Translating of Discontinuous Phrases
Michael H. Carl, Ecaterina Rascu · 2006
Translation of discontinuous phrases is a major challenge in Machine Trans-lation. Within METIS-II we developed a dictionary lookup strategy by mapping the items of a dictionary entry on non-adjacent words in an input text. Mapping is controlled through so-called contextual rejection, i.e. in-appropriate mappings are discarded if they fail to satisfy a predened set of constraints. We present various dictionary preprocessing steps to transform the entries into a suitable and more eective format for lookup. Then we describe the dictionary matching of discontinuous phrases. We illustrate this process on German verbs with detachable prexes and support verb constructions. 1
