Example Input: Great women's history . Not only the legal status but the personal outlooks of women changed immeasurably  in the period this book covers; the subtitle speaks of space and power, but Deutsch  has also given us a fine overview of intellectual change: what women thought, and  why they thought in those ways, during an era of astonishing industrial and social  development. Through her research, we can see why the women of Henry James  were not the same as those of F. Scott Fitzgerald--and they were very different.    We are used to sympathizing with the plight of working class women, and giving  great credit to the founders of the settlement houses and political groups that helped  them, but until now I had never realized how class differences affected attitudes, and  how perfectly reasonable women of either set found great difficulty in  understanding how those of the other thought and felt. This book has helped me get  a better understanding of both groups.      In recent months I've been reading heavily in Boston history and in women's history  of this period. This book is far and away the best thing I've found. Having done  historical research using primary sources, I can tell you this author has done an  immense amount of work, and it has paid off. She uses not only the minutes of  meetings and legal reports, but personal letters and contemporary novels to tell the  story. She writes clearly, and the book is well organized. If you want a real feel for  the lives of women during a period of tremendous change, this book is the best place  I know to get it. Deutsch straightens out a lot of misconceptions, and helps to clarify  an extremely complex period.
Example Output: POS

Example Input: Increase your Social IQ and Succeed in Business and Relationships! . At a time when people are more and more likely to communicate through text messaging and emails, instead of the deeper more nourishing and empowering exchange of a face-to-face, this book truly comes at the right time!     If you are in sales, or journalism, or you want to have a meaningful relationship, have a deep understanding of how to effectively lead a team by understanding what's happening past the overt representations of communication such as facial expression and vocabulary...    ...or just want to understand from a scientific observation what those little instincts and 'inner-senses' really mean and can do for you...    ...this book will take your understanding of the inner workings of social 'energy' to a new level.    Goleman takes the reader to deeper understanding of neuroscience and how humans are hardwired to respond in a number of varied (previously so mysterious), yet effective ways...if we just listen to what we're 'hearing/feeling'.    Humans are emotional and subconconscious sponges of life experience; and Goleman's 'Social Intelligence' great follow-up to his prior hit 'Emotional Intelligence' is the perfect material to beneficially get that deeper understanding and appreciation of your deep, neurological responses during person-to-person interactions

Example Input: Very disappointing. . I saw the Bill Moyer's PBS series on Huston Smith.  I was very impressed.  I bought The World's Religions by Huston Smith and was blown away.  Fantastic summaries of the 7 great world religions and a chapter on the lesser religions.    I've had the question nagging at the back of my mind for a while, "Does religion really matter?"  So, when coming across Why Religion Matters I knew I had to read it.    I didn't read the whole book.  I fell just short of 200 pages before giving up.  The book wasn't getting to the point.  It just kept bashing science and Scientism, over and over.    This is a dreadful book
