Michael pointed me to a story about how Stanford scientists put free text-analysis tool on the web<\/a>. The tool allows you to pass a text (or a Twitter hashtag) to an existing classifier like the Twitter Sentiment classifier. It then gives you a interactive graph like the one above (which shows tweets about #INKEWhistler14<\/a> over time.) You can upload your own datasets to analyze and also create your own classifiers<\/a>. The system saves classifiers for others to try.<\/p>\n

I’m impressed at how this tool lets people understand classification and sentiment analysis easily through Twitter classifications. The graph, however, takes a bit of reading – in fact, I’m not sure I understand it. When there are no tweets the bars go stable, and then when there is activity the negative bar seems to go both up and down.<\/p>\n","protected":false},"excerpt":{"rendered":"
