Description: Interlingua is a concept in the field of natural language processing that refers to a language used as a bridge between two or more languages in machine translation. This term originates from the need to facilitate communication and understanding between speakers of different languages, allowing a text in a source language to be translated into a target language through an intermediate language. The interlanguage can be a natural language, such as English, which is commonly used in translations, or an artificial language specifically designed for this purpose. The main characteristic of interlanguage is its ability to simplify and standardize the translation process, reducing the complexity that can arise when translating directly between multiple languages. In the context of natural language processing, interlanguage plays a crucial role in the development of machine translation systems, where the aim is to improve the accuracy and fluency of translations generated by machines. Its relevance has increased with the advancement of artificial intelligence and machine learning, which allow systems to learn and adapt to different languages and contexts, making interlanguage an essential tool in facilitating global communication.
