Machine Learning With Heart: How Sentiment Analysis Can Help Your Customers


When you think of artificial intelligence (AI), the word "emotion" doesn't typically come to mind. But there's an entire field of research using AI to understand emotional responses to news, product experiences, movies, restaurants, and more. It's known as sentiment analysis, or emotion AI, and it involves analyzing views – positive, negative, or neutral – from written text to understand and gauge reactions. Sentiment analysis can be used for survey research, social media analyses, and tracking psychological trends. Picture software that scans articles, reviews, ratings, and social media posts to determine sentiment changes for hotel guests.

Google's Sentiment Analyzer Thinks Being Gay Is Bad


Update 10/25/17 3:53 PM: A Google spokesperson responded to Motherboard's request for comment and issued the following statement: "We dedicate a lot of efforts to making sure the NLP API avoids bias, but we don't always get it right. This is an example of one of those times, and we are sorry. We take this seriously and are working on improving our models. We will correct this specific case, and, more broadly, building more inclusive algorithms is crucial to bringing the benefits of machine learning to everyone."

Artificial Intelligence--Existential Threat or Force for Good? - Content Loop


What are the first things that come to mind when someone says the words Artificial Intelligence? A technology that will cause job losses, large-scale economic upheaval and global conflicts, and which poses a threat to the role of humanity in the world? If your main reading is the mainstream media, you'd be excused for thinking so.

Google's sentiment analysis API is just as biased as humans


Google developed its Cloud Natural Language API to give customers a language analyzer that could, the internet giant claimed, "reveal the structure and meaning of your text." Part of this gauges sentiment, deeming some words positive and others negative. When Motherboard took a closer look, they found that Google's analyzer interpreted some words like "homosexual" to be negative. Which is evidence enough that the API, which judges based on the information fed to it, now spits out biased analysis. The tool, which you can sample here, is designed to give companies a preview of how their language will be received.

How to Prepare Movie Review Data for Sentiment Analysis - Machine Learning Mastery


We can use the split() function to split the loaded document into tokens separated by white space. We can use the data cleaning and chosen vocabulary to prepare each movie review and save the prepared versions of the reviews ready for modeling. One approach could be to save all the positive reviews in one file and all the negative reviews in another file, with the filtered tokens separated by white space for each review on separate lines. We can then call process_docs() for both the directories of positive and negative reviews, then call save_list() from the previous section to save each list of processed reviews to a file.



Q&A is even more straightforward than task-oriented spoken dialogue, as chatbots can provide answers directly to users' questions, such as "How much does an adult panda weigh?" In terms of IoT, Trio's technologies have been applied to a wide range of smart devices, including Xiaomi's Mi TVs, Mi AI speakers, and Smartisan smartphones.

Analyzing customer support interactions on Twitter with Machine Learning 7wData


In order to perform sentiment analysis, we used MonkeyLearn's public Twitter sentiment analysis module, which will classify tweets with positive, neutral or negative labels. On a given week, the average number of tweets mentioning a company (either by name or by handle) has AT&T on top, with an average of 64,000 tweets a week. To find out, we calculated the percentage of tweets of each sentiment -- positive, neutral or negative -- in the total of tweets for each company. Now when it comes to negative tweets, we were surprised: in proportion most companies receive less negative tweets than positive ones.

Find best hotel for vacation with Sentiment Analysis

Data Science 101: Sentiment Analysis in R Tutorial


For this tutorial, we're going to be using R and the Tidytext package to analyze how the sentiment of the State of the Union address, which is a speech given by the President of the United States to a joint session of congress every year. So this text has 117 negative polarity words and 240 positive polarity words. While it looks like there haven't been any strong trends over time, the line above suggests that presidents from the Democratic party (Clinton and Obama) have a slightly more positive sentiment than presidents from the Republican party (Bush Sr., Bush and Trump). So it looks like there is a reliable difference in the sentiment of the State of the Union addresses given by Democratic and Republican presidents, at least from 1989 to 2017.
