The main problem in machine translation is a linguistic problem. Language is ambiguous and the system tries to model a language on lexical and grammatical way. In order to solve this problem there are a lot of alternatives, e.g. a glossary related with the text’s topic can be used.
A controlled language with ten rules
Grammar rules are different for each language. Because of this, the rules for controlled languages are different from one language to another. And there are no rules that have optimal results for all languages. There are however rules which reduce ambiguities in most texts in many languages. By Muegge[who?] and according to CLOUT (Controlled Language Optimized for Uniform Translation) the following ten rules should be applied:
- Write sentences that are shorter than 25 words.
- Be brief ( well structured)
- Avoid ambiguity and subordination
- Evaluate the information
- Write sentences that express only one idea.
- Simple sentences
- Avoid ( gerunds, juxtaposition, etc.)
- Write the same sentence if you want to express the same content.
- Don’t be afraid to repeat
- Avoid synonyms
- Write sentences that are grammatically complete.
- Sentences grammatically and Orthographic correct
- Avoid ellipsis.
- Write sentences that have a simple grammatical structure.
- Avoid Juxtapostion, subordination, relatives pronouns, etc.
- Write sentences in the active form.
- Avoid passive voice
- Write sentences that repeat the noun instead of using a pronoun.
- Avoid pronouns like it, their, etc.
- Write sentences that use articles to identify nouns.
- Use the, this, etc.
- Write sentences that use words from a general dictionary.
- Do not use technical words
- Write sentences that use only words with correct spelling.
- Avoid mistakes
Benefits of using a controlled language
It is enabling to produce texts easier to read, more comprehensible and easier to retain, as well as with better vocabulary and style. Reasons for introducing a controlled language include:
- Documents that are more readable and comprehensible improve the usability of a product.
- Controlled-language guarantees giving objective and structured support in a typically rather subjective and unstructured environment.
- Tools-driven controlled language environments enable the automation of many editing tasks and provide objective quality metrics for the authoring process.
- More restrictive and controlled language, more uniform and standardized resulting source document and higher the match rate in a translation memory system, and the translation cost is cheaper.
- A controlled language designed for machine translation will significantly improve the quality of machine-generated translation proposals and it will reduce the time and cost of human translators editing.
Controlled language and translation
One of the biggest challenges facing organizations that wish to reduce the cost and time involved in their translations is the fact that even in environments that combine content management systems with translation memory technology, the percentage of un-translated segments per new document remains fairly high. While it is certainly possible to manage content on the sentence/segment level, the current best practice seems to be to chunk at the topic level. Which means that reuse occurs at a fairly high level of granularity.
