Visual presentation communicates information clearly and effectively through graphical means. WikiSummarizer is a Web-based application that summarizes Wikipedia articles and presents them as Visual Summaries, Tree Views and Keyword Clouds with links to Wikipedia Knowledge Base.

WikiSummarizer is an interactive learning and teaching tool providing effective graphical visualization that reduces complex information and provides clear and attractive presentation of the essential points. The interactive summaries are easily shared and published in blogs, websites and documents as digital Visual Summaries, Tree Views and Keyword Clouds.

It is easy to collaborate and mine information using the WikiSummarizer summaries in blogs, websites, word editors, browsers, mind mapping applications, databases and content management systems.

This Visual Summary presents the keywords and the summaries of the Wikipedia article about "Sulfur". The Visual Summary map and the Keyword Cloud were automatically created by WikiSummarizer.

Essential Summary

Wikipedia article:  Sulfur

Sulfur

Sulfur (100)

·         Under normal conditions, sulfur atoms form cyclic octatomic molecules with chemical formula S8.

·         Elemental sulfur is a bright yellow crystalline solid when at room temperature.

·         Elemental sulfur crystals are commonly sought after by mineral collectors for their brightly colored polyhedron shapes.

·         Many sulfur compounds are odiferous, and the smell of odorized natural gas, skunk scent, grapefruit, and garlic is due to sulfur compounds.

·         Sulfur is an important part of many enzymes and in antioxidant molecules like glutathione and thioredoxin.

·         In most forest ecosystems, sulfate is derived mostly from the atmosphere; weathering of ore minerals and evaporites contribute some sulfur.

·         Fossil-based sulfur deposits from salt domes have until recently been the basis for commercial production in the United States, Poland, Russia, Turkmenistan, and Ukraine.

·         Today, sulfur is produced from petroleum, natural gas, and related fossil resources, from which it is obtained mainly as hydrogen sulfide.

·         This process entails oxidation of some hydrogen sulfide to sulfur dioxide and then the comproportionation of the two: Owing to the high sulfur content of the Athabasca Oil Sands, stockpiles of elemental sulfur from this process now exist throughout Alberta, Canada.

·         Reduction of elemental sulfur gives polysulfides, which consist of chains of sulfur atoms terminated with S centers: This reaction highlights arguably the single most distinctive property of sulfur: its ability to catenate (bind to itself by formation of chains).

·         Not all organic sulfur compounds smell unpleasant at all concentrations: the sulfur-containing monoterpenoid grapefruit mercaptan in small concentrations is responsible for the characteristic scent of grapefruit, but has a generic thiol odor at larger concentrations.

·         Being abundantly available in native form, sulfur (Latin sulphur) was known in ancient times and is referred to in the Torah (Genesis).

·         Elemental sulfur is mainly used as a precursor to other chemicals.

·         Reduced glutathione, a sulfur-containing tripeptide, is a reducing agent through its sulfhydryl (-SH) moiety derived from cysteine.

About Context Discovery WikiSummarizer

WikiSummarizer is a Web-based summarization portal that summarizes Wikipedia articles and presents the results as a structured outline, a Visual Summary and a Keyword Cloud.

The Visual Summary can be navigated in any browser on Windows, Mac, Linux, iPhone, iPad and Android devices.

The Keyword Cloud is linked with Wikipedia Knowledge Base. When you click on the keyword in the cloud you will be presented with an instant Visual Summary.

The keywords and summaries are easily exported to other applications such as word editors, browsers, mind mapping applications like Mindjet MindManager, MindGenius, XMind, and any other mind mapping application.

The summaries are stored in a knowledge library.

Report writers can be easily used for knowledge mining of the summaries, keywords and links. The Wikipedia Knowledge Base search function works as a back-of-the-book index pointing to the most relevant summaries and links.
