Corpora in Translation Studies

Corpora in Translation Studies
Gradually the translator’s workplace has changed over the last ten years. Personal computers now have the capacity to process information easier and quicker than ever before, and so today's computer could be considered an important or even essential tool in translation. However, problems arise in the use of computers in translation, as the computer is no substitute for traditional tools such as monolingual and bilingual dictionaries, terminologies and encyclopaedias on paper or in digital format and although we can easily access a large amount of information, we need to find the right and reliable information.
Here Corpora and concordancing software play an important role since gaining access to information about language, content and translation practices which was hardly available to translators before the present stage of ICT development.
Machine Translation based on Corpus.
Machine translation from corpus linguistics is based in the analysis of real samples with its own translations. Among the different devices that use corpus, there are statistical methods and based on examples.
Statistical Methods.
The main objective of statistic machine translation is to generate translations from statistical methods based in corpus of bilingual texts. For instance European parliament minutes are written in all EU (European Union) official languages. If there were more of this corpus, we would get excellent results of translation of texts about those subjects. 
The first statistic machine translation program was CANDIDE by IBM.
Based on examples.
Machine translation based on examples is well known for using a bilingual corpus as the main source of knowledge. Basically it’s an analogical translation and could be interpreted as a practice of cases reasoning used in automatic learning, which consists in solving a problem basing on solutions of others similar problems.
Corpora and Translation.
Translation typology.
According to EAGLES, we can make a general distinction between Monolingual and Multilingual corpora. At the same time in multilingual corpora, we can distinguish between Comparable corpora and Corpora compiled using similar design criteria but which are not translations.
Parallel or Translation corpora are texts in one language aligned with their translation in another. We have to take into account several variables like directness of translation, number of languages, etc.
There are many Monolingual Comparable Corpora (corpus composed in two sub-sections, one of original texts in one language and the other texts translated into the same language). It’s useful for translation theorists and researchers but professional technical translators use translation memories.
Defining Translation memories.
Translation memory is a very specific type of parallel corpus in that:
Translation workbenches and TMs could be considered the most successful translation tool; however it’s restricted to specific text types.
Corpora aids in Translation.
The previous kinds of corpora can be combined with other tools like a dictionary for example. Corpora can function as general or specialized dictionaries. In that way, Comparable corpora can be seen as a monolingual dictionary and Parallel corpora could be compared to a bilingual dictionary.
Corpus resources for Translators.
Not all dictionaries are the same, and neither are all corpora.
Apart from translation memories, corpus resources with a potential use for professional translators could be classified from “robust” to “virtual”.
Some examples of corpora could be BNC (British National Corpus) or the Spanish corpus CREA or the Italian CORIS and so on.
It’s important to mention the difference by corpus linguistics between corpora and archives of electronic texts; the second one is only a repertory of electronic texts.
Building a corpus of web pages implies an information retrieval operation, in order to locate relevant and reliable documents.
In many translation classes students have made their own corpora with DIY (do it yourself) corpora. 
The main benefits of DIY corpora may be summarized as follows: 
Finally the advantages of “robust” corpora that we can see over “virtual” corpora are the following:
