#ARTEL14 Tweet Analytics

http://crunch.kmi.open.ac.uk/people/~fwild/services/tweetalytics-artel14.Rmw

This analysis looks into the outreach we reached on twitter for the 4th Workshop on Awareness and Reflectin in TEL (#ARTEL14). This analysis has the following limits: it only looks into those tweets that contained the tag “#artl14”. This is a serious limitation, as there have been many more tweets about it using different tags or phrases (such as the keyword “ARTEL14” instead ot the tag). Error: undefined columns selected. By now (this is a live updating script), we have 237 users who tweeted 288 tweets.

Dont forget that click rates of the bitly links are not equal to actual downloads, they indicate mere trends! The following retweets can be identified:.

Sentiment detection using the Harvard General Inquirer dictionaries. This is an example of using just two out of the dictionaries provided in the Harvard General Inquirer. First, we load the R data set for the selected dictionaries (positive words, negative words) that were interested in. This data set has been created with the following script, selecting only two of the 182 categories. Now, lets fetch a few tweets. Gs = getURI(https:/ docs.google.com/spreadsheet/pub?

Interrater agreement with Krippendorff's alpha coefficient

http://crunch.kmi.open.ac.uk/people/~fwild/services/interrater-agreement.Rmw

Interrater agreement with Krippendorffs alpha coefficient. One approach to evaluate novel approaches for predicting learning performance is to compare the machines prediction with human judgement. As humans are not flawless either, an important step in describing the quality of such gold standards is to use multiple human raters - and measure their interrater agreement with, for example, Krippendorffs Alpha coefficient. R provides an implementation of it in the package irr. There are missing values, sinc...

Prediction with linear models

http://crunch.kmi.open.ac.uk/people/~fwild/services/prediction.Rmw

Prediction with linear models. There are many different ways of how to predict data based on past observations. One particularly interesting family of statistical prediction models can be found in linear models. Here is a simple example of how to create such prediction, measure its goodness of fit, and visualise this. We can first see if the variables correlate with each other. Cor(ct, method = spearman). M = lm(grade age freq var2, data = ct) anova(m). RSS = sum(residuals(m) 2). Lets try another linear ...
