Smart search engine Wolfram Alpha has become a very clever

Service engine Wolfram Alpha knowledge acquired pay accounts. Their owners will be given a lot of additional tools, including the ability to analyze files and images.

Wolfram Alpha creator of the British mathematician Stephen Wolfram (Stephen Wolfram) has announced the launch of the Pro version of its service, which he calls the machine a knowledge base.

Opened in May 2009, a web service Wolfram Alpha is like a search engine, but the principle of its operation is somewhat different. He gives no reference to the relevant sites that contain the necessary information, and direct answers.

Questions for this may relate to a variety of areas, both areas of life, and scientific disciplines. The official website of Wolfram Alpha in the examples mentioned 30 chapters in which the user can ask questions, including people, history, geography, physics, chemistry, materials, capital markets, music, sports, finance, etc.

It is also possible to compare the issues. For example, a user may ask to compare the personal assets of Bill Gates and Warren Buffett. In this case, simply enter a search string «net worth bill gates vs warren buffet». In addition to the current values ​​of the system will present graphs of savings over time.

In addition to text queries, the user can enter mathematical expressions, and Wolfram Alpha will compute them.

The knowledge base system is wide enough, especially in science. For example, you can ask about any rare plants and animals.

The essence of innovation - Wolfram Alpha Pro - is the appearance of new methods of data input and output.
