Machine Translation Capitalization via Source Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine translation systems face challenges in capitalizing translated text effectively, particularly due to capitalization ambiguities and the limitations of monolingual solutions that do not perform well on poorly translated text or source text with special use capitalization.
Innovation Solution
A method that involves automatically translating a capitalized source text to a target text and capitalizing the target text based on the capitalized source text, using a combination of monolingual capitalization models and phrase alignment to determine the best capitalized sentence by generating and evaluating multiple capitalization configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If monolingual capitalization models are used, then the capitalization process is simple, but the accuracy deteriorates on badly translated text and source text with special use capitalization
Solution Approach 1:
The patent combines monolingual capitalization models with bilingual translation information to create a hybrid capitalization system. This merging allows the system to leverage both the simplicity of monolingual models and the accuracy of bilingual context, particularly for handling badly translated text and special use capitalization cases.
Solution Approach 2:
The patent introduces bilingual translation information as an intermediary element that mediates between the source text and target text capitalization processes. This intermediary provides additional contextual information that helps resolve capitalization ambiguities that neither purely monolingual nor traditional bilingual approaches can handle effectively.
2Ease of operation
If capitalization tags are associated with lowercase words, then the capitalization process is straightforward, but capitalization ambiguities occur where each word can have more than one tag
Solution Approach 1:
The patent implements feedback mechanisms where the capitalization model continuously refines its predictions by considering multiple possible tags and using bilingual translation information to disambiguate between them. The system evaluates different capitalization hypotheses and uses feedback from the translation context to select the most appropriate tags.
Solution Approach 2:
The patent changes the parameters of the capitalization model by incorporating bilingual translation information and multiple feature types (capitalization features, translation features, alignment features). This parameter expansion allows the model to distinguish between different capitalization contexts that would otherwise be ambiguous.
3Productivity
If traditional machine translation systems are used, then the translation process is efficient, but the capitalization of translated text is poor
Solution Approach 1:
The patent applies preliminary capitalization action by generating candidate capitalizations during the translation process itself, rather than as a separate post-processing step. This allows the capitalization information to be integrated into the translation workflow, maintaining efficiency while improving quality.
Solution Approach 2:
The patent merges the translation process with the capitalization process by integrating capitalization model predictions with translation output generation. This combination allows both functions to work together synergistically, improving capitalization quality without significantly impacting translation efficiency.

AI summary
A system and method for capitalizing translated text is provided. A capitalized source text is automatically translated to a target text. The target text is capitalized according to information in the capitalized source text.
