Ex Input:
AL BUEN ENTENDEDOR... . Esta novela es a la literatura lo que la planta nuclear de Chernobyl es al medio ambiente

Ex Output:
NEG

Ex Input:
Unsuitable for undergraduates . The original Mechanical Engineering Design book written by Joseph Shigley, and later, with Larry Mitchell, was an excellent undergraduate text; it was readable at the introductory level, and it contained enough information and methodology for use as a good reference book after graduation. Unfortunately, this revised text, which was rewritten by Charles Mischke, is thoroughly unreadable, obfuscating, and is totally unsuitable as a text for undergraduate mechanical engineering students. The book is full of nuances, subtleties and informative data that do make it useful as a reference book on the shelf of an experienced design engineer, but not as a text for students learning the subject. For those who plan to teach a course for mechanical engineering majors on this topic, I recommend other texts such a Jack Collins' Mechanical Design of Machine Elements and Machines, Wiley, 2003

Ex Output:
NEG

Ex Input:
not worth the money . A mediocre, intellectually lazy piece of work that will be of moderate value to beginners. Its basic points are valuable to those who have not been exposed to this structure, but it sorely lacks depth, committment to its subject, or the information value to hold the interest of a reader of above average mental capacity.

Ex Output:
NEG
