Real-time Twitter sentiment analysis with Azure Stream Analytics


Specifically, to identify trending topics in real time on Twitter, the company needs real-time analytics about the tweet volume and sentiment for key topics. We have created a client application that connects to Twitter data via Twitter's Streaming APIs to collect Tweet events about a parameterized set of topics. Then enter your data for the Twitter API Key and Secret, Twitter Access Token and Secret, and also the event hub information. Now that Tweet events are streaming in real time from Twitter, we can set up a Stream Analytics job to analyze these events in real time.

Sentiment Analysis of Movie Reviews (2): word2vec


If we want to find similarities between words, we have to look at a corpus of texts, build a co-occurrence matrix and perform dimensionality reduction (using, e.g., singular value decomposition). Using so-called distributed representations, a word can be represented as a vector of (say 100, 200, … whatever works best) real numbers. And as we will see, with this representation, it is possible to model semantic relationships between words! This makes a lot of sense: So amazing is most similar, then we have words like excellent and outstanding.

How to Build an Email Sentiment Analysis Bot: An NLP Tutorial


There are many ways to accomplish this, but for the sake of simplicity, let's set up a simple web server and use Sendgrid's inbound parse hook to pipe emails to the server. So we have a sentiment analyzer program written in Java and an email bot written in Python. We have built an email bot that is able to receive emails, perform sentiment analysis, and determine if an email requires immediate attention. In this article, you learned how to build an email sentiment analysis bot using the Stanford NLP library.

Opinion Mining - Sentiment Analysis and Beyond


It will help us break a sentence down into its underlying grammatical structure – nouns, verbs, adjectives etc. The Viterbi algorithm computes a probability matrix – grammatical tags on the rows and the words on the columns. So, the probability of "will" being MD given Janet is NNP – Of NNP followed by MD * probability of "will" being MD 0.000009 * 0.0110 * 0.308431 0.00000002772 Janet only had non-zero scores for one tag so this was easy. Once the sentence has been grammatically tagged, we can use production rules to mine opinions and extract meaningful feedback that might help us solve business problems.
