Mining Twitter for Airline Consumer Sentiment. Airlines, Consumers, and Twitter Anyone who travels regularly recognizes that airlines struggle to deliver a consistent, positive customer experience.

Mining Twitter for Airline Consumer Sentiment

Through extensive interview and survey work, the American Customer Satisfaction Index ( quantifies this impression. As a group, airlines falls at the bottom of their industry rankings, below the Post Office and insurance companies: Meanwhile, the immediacy and accessibility of Twitter provides a real-time glimpse into consumer's frustration: This tutorial demonstrates how to use R to collect tweets and apply a (very) naive algorithm to estimate their emotional sentiment.

R & SPlus XML Parsers

Untitled. Abstract The idea here is to provide simple examples of how to get started with processing XML in R using some reasonably straightforward "flat" XML files and not worrying about efficiency. Here is an example of a simple file in XML containing grades for students for three different tests. <? Xml version="1.0" ? ><TABLE><GRADES><STUDENT> Fred </STUDENT><TEST1> 66 </TEST1><TEST2> 80 </TEST2><FINAL> 70 </FINAL></GRADES><GRADES><STUDENT> Wilma </STUDENT><TEST1> 97 </TEST1><TEST2> 91 </TEST2><FINAL> 98 </FINAL></GRADES></TABLE>

A Short Introduction to the XML package for R. To parse an XML document, you can use xmlInternalTreeParse() or xmlTreeParse() (with useInternalNodes specified as TRUE or FALSE) or xmlEventParse() . If you are dealing with HTML content which is frequently malformed (i.e. nodes not terminated, attributes not quoted, etc.), you can use htmlTreeParse() . You can give these functions the name of a file, a URL (HTTP or FTP) or XML text that you have previously created or read from a file.

If you are working with small to moderately sized XML files, it is easiest to use xmlInternalTreeParse() to first read the XML tree into memory.

R preferred by Kaggle competitors. Kaggle, the predictive-analytics competition site, has analyzed the preferences of the 2,500 data scientists who participate in its competitions, and R was the most-preferred software of the competitors at 22.5%. The next-nearest alternative was Matlab, at 16%. On a related note, the premier of the Australian state of New South Wales has just launched a competition on Kaggle to predict the traffic on Sydney's M4 motorway.
