Computer-assisted translation,computer-aided translation or CAT is a form of language translation in which a human translator uses computer hardware to support and facilitate the translation process.[1]
Computer-assisted translation is sometimes called machine-assisted, or machine-aided translation (not to be confused with machine translation).
The automatic machine translation systems available today are not able to produce high-quality translations unaided: their output must be edited by a human to correct errors and improve the quality of translation. Computer-assisted translation (CAT) incorporates that manual editing stage into the software, making translation an interactive process between human and computer.[2]
Some advanced computer-assisted translation solutions include controlled machine translation (MT). Higher priced MT modules generally provide a more complex set of tools available to the translator, which may include terminology management features and various other linguistic tools and utilities. Carefully customized user dictionaries based on correct terminology significantly improve the accuracy of MT, and as a result, aim at increasing the efficiency of the entire translation process.
Range of tools[edit]
Computer-assisted translation is a broad and imprecise term covering a range of tools, from the fairly simple to the complicated. These can include:
- Translation memory tools (TM tools), consisting of a database of text segments in a source language and their translations in one or more target languages.[3]
- Spell checkers, either built into word processing software, or available as add-on programs
- Grammar checkers, either built into word processing software, or available as add-on programs.
- Terminology managers, which allow translators to manage their own terminology bank in an electronic form. This can range from a simple table created in the translator's word processing software or spreadsheet, a database created in a program such as FileMaker Pro or, for more robust (and more expensive) solutions, specialized software packages such as SDL MultiTerm, LogiTerm, Termex, TermWeb, etc.
- Electronic dictionaries, either unilingual or bilingual, also known as dictorobotary
- Terminology databases, either on the host computer or accessible through the Internet, such as TERMIUM Plus or Grand dictionnaire terminologique from the Office québécois de la langue française
- Full-text search tools (or indexers), which allow the user to query already translated texts or reference documents of various kinds. Some such indexers are ISYS Search Software, dtSearch Desktop and Naturel
- Concordancers, which are programs that retrieve instances of a word or an expression and their respective context in a monolingual, bilingual or multilingual corpus, such as a bitext or a translation memory
- Bitext aligners: tools that align a source text and its translation which can then be analyzed using a full-text search tool or a concordancer
- Project management software that allows linguists to structure complex translation projects in a form of chain of tasks (often called "workflow"), assign the various tasks to different people, and track the progress of each of these tasks.
