Task: Sentiment Analysis
Input (English): Review: Gifford is one of the top experts on Heinlein's works, and his "A Reader's Companion" is an exhaustively researched and well-thought-out compendium of nearly all of Heinlein's work.I say "nearly" only because the book misses a few Heinlein collections and such that have been published in the few years since Gifford's 2000 printing. [...]I've been collecting Heinlein works for years, even very obscure ones, and I still learned of new things from Gifford's book. 
 Polarity: Negative
Output (English): False
