This repository contains the iPython notebook and training data to accompany the O'Reilly tutorial on sentiment analysis with LSTMs in Tensorflow. Cleaning and pre-processing text data is a vital process in data analysis and especially in natural language processing tasks. Strip the data set of reviews of irrelevant characters including HTML tags, punctuation, and emojis using regular expressions. Compared to the state-of-the-art algorithms, our main contribution to this area is two-fold: rst, we propose Sen-tribute, an image-sentiment analysis algorithm based on 102 mid-level attributes, of which results are easier to interpret and ready-to-use for high-level understanding. Sentiment is positive if closer to 1 and negative if close to 0. The sentiment property returns a named tuple of the form Sentiment (polarity, subjectivity).
