The term text analytics describes a set of linguistic, statistical, and machine learning techniques that model and structure the information content of textual sources for business intelligence, exploratory data analysis, research, or investigation.notably life-sciences research and government intelligence. The term text analytics also describes that application of text analytics to respond to business problems, whether independently or in conjunction with query and analysis of fielded, numerical data.These are among the key findings of a national survey of dating and relationships in the digital era, the first dedicated study of this subject by the Pew Research Center’s Internet Project since 2005.One in every ten American adults has used an online dating site or a mobile dating app.Nineteen of 203 patients treated with statins and 10 of 217 patients treated with placebo met the study definition of myalgia (9.4% vs 4.6%. This finding did not reach statistical significance, but it indicates a 94.6% probability that statins were responsible for the symptoms. that statins were responsible for the symptoms in about half of the treated patients.” I doubt if statins caused the myalgia in the untreated patients.Disregarding the statistical issues involving NHST and posterior probability, I assume that the author means to say ” . Kaiser Fung shares an amusing story of how you can be misled by analyzing data that you haven’t fully digested.Text mining, also referred to as text data mining, roughly equivalent to text analytics, is the process of deriving high-quality information from text.
In literature, this would not be surprising—we don’t demand or even expect that Matthew Klam, Francis Spufford, Alison Bechdel, etc., find collaborators—but in science it seems like a mistake to work alone. Andrew Wiles didn’t seem to require a research team or even a research partner.The effect had disappeared, and with it, Motyl's dreams of youthful fame It turned out that the problem was not in the data or in Motyl's analyses.It lay in the surprisingly slippery nature of the P value, which is neither as reliable nor as objective as most scientists assume. I do cover some of these issues in my class on Communicating Data and Statistics, though. For example, here’s a long post from a few months ago on cellular automata and physics. I’d love to lead a seminar on the philosophy of statistics, unfortunately I suspect that here at Columbia this would attract approximately 0 students.For a brief moment in 2010, Matt Motyl was on the brink of scientific glory: he had discovered that extremists quite literally see the world in black and white.
