In accordance with this description, NLP is conceived as ¡°human language engineering or technology¡±. Therefore, NLP requires consistent description of linguistic facts on every linguistic level: morphological, syntactic, semantic, and even the level of pragmatics and discourse. Besides the linguistically-motivated conception of NLP, we emphasize the origin of such research area, the place occupied by NLP inside a multidisciplinary scenario, their objectives and challenges. %K Natural Language Processing %K Human Language Technology %K Computational Linguistics %K Linguistics %K natural language. %U http://portalrevistas.ucb.br/index.php/RL/article/view/786/825
