ABSTRACT
We present a cost-based (or energy-based) model of disambiguation. When a sentence is ambiguous, a parse with the least cost is chosen from among multiple hypotheses. Each hypothesis is assigned a cost which is added when: (1) a new instance is created to satisfy reference success, (2) links between instances are created or removed to satisfy constraints on concept sequences, and (3) a concept node with insufficient priming is used for further processing. This method of ambiguity resolution is implemented in DMTRANS PLUS, which is a second generation bi-directional English/Japanese machine translation system based on a massively parallel spreading activation paradigm developed at the Center for Machine Translation at Carnegie Mellon University.

Ambiguity resolution for machine translation of telegraphic messages
ACL '98/EACL '98: Proceedings of the 35th Annual Meeting of the Association for Computational Linguistics and Eighth Conference of the European Chapter of the Association for Computational LinguisticsTelegraphic messages with numerous instances of omission pose a new challenge to parsing in that a sentence with omission causes a higher degree of ambiguity than a sentence without omission. Misparsing induced by omissions has a far-reaching ...
Resolution of ambiguity in parsing
The use of context-free grammars to define the syntax of programming languages is complicated by the phenomenon of ambiguity. Ambiguity can be resolved by the specification of a unique canonical parse. A set of rules is given which defines a canonical ...
Translation ambiguity resolution based on text corpora of source and target languages
COLING '92: Proceedings of the 14th conference on Computational linguistics - Volume 2We propose a new method to resolve ambiguity in translation and meaning interpretation using linguistic statistics extracted from dual corpora of source and target languages in addition to the logical restrictions described on dictionary and grammar ...
