Abstract:     In a machine translation method and apparatus, an input text analyzer analyzes an input text in a first language to form a graph structure of nodes and edges. An equivalent selector introduces variables to ambiguous components of the graph structure by a variable introducer. A constraint solver propagates constraints on the variables to other components. Solutions are then found for equivalent determination and locally consistent solutions are also found for the respective components. A variable realizer finds solutions to the respective locally consistent components according to the patterns of the variables. An output text generator then generates text in a second language from a set of these solutions. Thus, the method and apparatus enable avoidance of an explosion of combinations between source words and equivalents capable of occurring in the analysis phase and also enables the optimum use of information through deferring the determination of words or phrases in the second language of ambiguous components to the text generation phase.

First Claim:
Show all 9 claims
We claim:     1. A machine translation method of analyzing the structure of a text in a first language to be translated and transforming said text into a text in a second language comprising the steps of:
  • substituting an ambiguous component in either a semantic or modificatory sense, or both, in the structure of said analyzed text with a variable denoting said ambiguous component and having constraint information;
  • transforming another component in the structure of said analyzed text into said second language using a bilingual translation dictionary to uncover information about said another component; and
  • transforming the component substituted with said variable into said second language by using said uncovered information about said another component to resolve said ambiguous component.
