Role of Machine Translation and Word Sense Disambiguation in Natural Language Processing

Natural language is most common way to communicate with each other but sometime we can’t understand other languages to understand different languages machine translation is needed. Machine translation is the best application which helps to understand any other language in less cost and less time. In this some problems are faced by researchers: words which pronounce same but having different meaning, some words spelled different but having same meaning, in some cases combination of words may change the meaning. To resolve such kind of problems Word Sense Disambiguation is needed. Word Sense Disambiguation is used to understand the correct meaning of the word with respect to context in which that is used; Word Sense Disambiguation is the part of natural language processing. Word Net plays an important role in Word Sense Disambiguation. In this paper, we will discuss about the basic concept of Natural language processing, Machine Translation and Word sense disambiguation.
