Machine translation is gaining a strong momentum in the 21st century translation world. Users have lauded their excellent speed and faster turn-around time which assures immediate translation. From CAT tools to portable machine translation devices to translation apps, there are lots to choose from today.
In fact, it won’t be exaggerating to state that machine translators have made our life easier. For example, let’s say you are traveling in a foreign country and you don’t know the local language. So, you will need immediate translation assistance every time you go to a market or take a public transport in that foreign country. Now, you are not a political leader who will be accompanied by an interpreter always. In such a situation, a portable translator machine will straight out the things for you. They are designed to offer immediate translation so that you can get the translation assistance just when you will need it. Some of these translators offer one-way translation but the more modern ones even allow two-way translation like Muama Enence.

However, machine translation covers a wide area and there are various types or approaches to study here.
RBMT stands for “Rule-Based Machine Translation”. The process parses source sentence for identifying words and analyzing the structure. Based on the analysis, RBMT converts it right into target language.
RBMT’s advantage is that a quality engine is able to translate a vast scope of texts yet without incorporating big bilingual corpora. But, then, it’s really labor-intensive and time-consuming to develop RBMT systems. Moreover, it also can’t cover the different linguistic phenomena which results in poor translation when you have to translate real-life texts.
SMT is the acronym of “Statistical Machine Translation”.
The process works through training translation engine via volumes of monolingual and bilingual corpora. SMT seeks to find statistical correlations in between the source texts & translations and build a translation model. Then, it creates confidence scores which indicate how much a specific source text would map to translation. Now, the very translation engine here has no idea of grammar or language rules and hence can’t assure 100% accuracy with translation. You must have been aware of the translation tools of famous search engines such as Bing Translator or Google Translate. These all use SMT translation approach.
The best bit about SMT is that it reduces hassles of handcrafting specific translation engines to cater to every language pair.
The latest entry into the machine translation scene, NMT stands for “Neural Machine Translation”. It deploys neural networks which comprises of nodes strategically modeled on human brain. These nodes are able to hold single phrases, words or even longer segments. In fact, these can relate to one another through a network of complex bonds – that are based on the bilingual texts deployed to train this system. The very dynamic and complex nature of these networks allows creation of better educated guesses which lead to higher quality of translation. NMT systems demand solid processing power as they are constantly learning as well as adjusting to bring the best possible output.
Now, all these approaches mentioned above have their specific drawbacks. Thus, the experts today are increasing stressing on a hybrid approach to machine translation that can draw the bests from these systems and negate the pitfalls. There are three options for the hybrid concept. One refers to rule-based engines deploying statistical translation in post processing as well as cleanup phases. The other one is statistical translation systems which would be guided by the rule-based engines. The last one is any one from the above accompanied by inputs from neural MT system.
