Task: Sentiment Analysis
Input (English): Good start . I've used some version of this book for many years now, and I've seen it evolve.  I think, as other reviewers have said, that there are some simplified portions of the book, especially those parts dealing with monetary economics.  There are other portions which lay out the principles as only these authors can, and those parts are extremely helpful and valuable.  This book allows me to teach my notes and thoughts with a textbook serving as a reference and an introduction -- it doesn't get in my way, in other words.  I use it along with several other texts, and I think it gets the job done.  Students seem to like it as well, mainly for its clarity.  For someone wanting to learn the basics, this is an excellent choice
Output (English): POS
