summBot is a Summarizer Chrome Extension that analyzes the document tree of the article being viewed and displays a summary of it. It analysis the text by frequency of word use over all the sentences.
summBot is very easy to use. When viewing an article (e.g. Wikipedia, news site, etc.), simply select a word in the article and right-click on it. From the resulting drop-down menu, select "Summarize article...". If the article is extremely long, summBot may take some time to process it. While it's processing the article, the summBot icon in the top-right of Chrome will have a blue square. Once it's finished, it will display a green square and you can view the summary by clicking on summBot's icon.
Currently, summBot's summary technique is fairly simplistic. I'm hoping to make its summarizing algorithm far more interesting and effective when I have more time.
