The Processing of Natural Languages – brief PLN, or NLP- is a subdiscipline of the Artificial Intelligence and the branch engineer of the linguistics computational. The PLN deals with the formulation and investigation of effective mechanisms computationaly for the communication between persons or between persons and machines by means of natural languages. The PLN does not try of the communication by means of natural languages of an abstract form, it tries to design mechanisms to communicate that they should be effective computationaly – that could carry out by means of programs that they execute or simulate the communication-.
The applied models focuses not only on the comprehension of the language of for yes, but on general cognitive human aspects and on the organization of the memory. The natural language uses only as way to study these phenomena.
We should now something of its history:
The Processing of the Natural Language (PLN) is one of the angular early stones of the artificial intelligence (IA). The automatic Translation, for example, was born at the end of the decade of the forties, before there was coined its own expression ” Artificial Intelligence “. Nevertheless, the PLN has recovered multiple roles in the context of the IA, and its importance inside this field has grown and decreased as a result of technological and scientific changes.
The first attempts of translating texts for computer at the end of the forties and during the fifties failed due to the scanty power of the computers and to the scanty linguistic sofistificación. Nevertheless, the efforts realized in the decades of the sixties and the seventies to produce interfaces in natural language for databases and other computer applications obtained a certain significant degree of success. The decade of the eighties and the beginning of that of the nineties have seen the investigation re-arose in the area of the Automatic Translation.
