***** Twitter as research tool is often overlooked but always valuable. How cool is extracting sentiment analysis from past tweets on a subject:
"Many such tools are available in the R package (text mining). These allow patterns in the text to be identified, and codified so that they are amenable to statistical investigation. An important subset of these tools comprises methods of sentiment analysis – whereby numerical scores can be assigned to tweets as a means of evaluating the strength and direction of the writer’s reaction to certain key words. These methods of analysis commonly make use of lists of words with positive and negative connotations, and make use both of the presence of such words and their position within the structure of a sentence."
Cool artile and tools. Marty
