U.S. News

"American consumers continued to disagree with themselves in June as consumer confidence has remained high but has still not translated into much higher consumption," Eugenio Alemán, a senior economist at Wells Fargo Securities, wrote in a research note Friday. "Although personal consumption expenditures are expected to bounce back during the second quarter of the year, the bounce back may not be as strong as what we were expecting if these numbers remain as they were originally published, which is a big if."

For our case we only consider Text feature of the Tweet as we are interested on the review of the movie. We can also use the other features such as Latitude/Longitude, replied to, etc. do other analysis on the tweeted data.


How Can Natural Language Processing Change Business Intelligence?

#artificialintelligence

So having quick access to information is critical for making rational business decisions. BI is an umbrella term that refers to a variety of software applications used to analyze data and support a wide spectrum of business decisions, ranging from operational to strategic. Another promising area of NLP application in BI is sentiment analysis -- the use of natural language processing techniques to extract subjective information from a piece of text, also known as Opinion Mining. In our next article that will come soon we will review and compare the TOP Natural Language Processing APIs -- make sure not to miss it!

Real-time Twitter sentiment analysis with Azure Stream Analytics

#artificialintelligence

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

@machinelearnbot

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

@machinelearnbot

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

@machinelearnbot

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.
