Pre-editing is the process whereby a human prepares a document before applying

machine translation Machine translation is use of computational techniques to translate text or speech from one language to another, including the contextual, idiomatic and pragmatic nuances of both languages. Early approaches were mostly rule-based or statisti ...

. The main goal of pre-editing is to reduce the post-editing workload by adapting the source document to improve the raw output of the machine translation. Pre-editing could be also valuable for human translation projects since it can increase the application of the

translation memory A translation memory (TM) is a database that stores "segments", which can be sentences, paragraphs or sentence-like units (headings, titles or elements in a list) that have previously been translated, in order to aid human translators. The trans ...

. In general, pre-editing is worth to apply when there are more than three target languages. In this case, pre-editing should facilitate the process of machine translation by spell and grammar checking, avoiding complex or ambiguous syntactic structure, and verifying term consistency. However, it is also applicable to poorly-converted files.Combining pre-editing and post-editing to improve SMT of user-generated content
Gerlach J., Porro V., Bouillon P., Lehmann S., in: Proceedings of the Machine Translation Summit XIV, Nice, France, 2013. Linguistic pre-editing is more important than pre-editing of the format since errors can affect machine translation quality.
