Wolfram alpha®

  1. 1. Wolfram Alpha® computational™ knowledge engine By : Aatman Kothari
  2. 2. OUTLINE • • • • • • • • • • Introduction History Working Components Technology Possibilities Partners Advantages or Usages Conclusion Bibliography
  3. 3. Introduction • Also written as WolframAlpha or Wolfram|Alpha. • It is a computational knowledge engine or answer engine. • It was released on 15th May 2009. • It answers factual queries by computing the answers for “externally sourced curated data”.
  4. 4. Intro continued.. • It is mostly based on wolfram’s earlier product Mathematica. • Mathematica a computational toolkit that encompasses computer algebra, symbolic and numerical computation, visualization, and statistics capabilities. • Mathematica is a computational software program used in many scientific, engineering, mathematical and computing fields. It was conceived by Stephen Wolfram and is developed by Wolfram Research of Champaign, Illinois.
  5. 5. History Project lead by Stephen Wolfram  It is the culmination of 5 years of work, and 25 more years of previous development  Stephen started Wolfram Research in 1987, focusing mainly on the Mathematica software 
  6. 6. History Continued.. • In 2002 Stephen publishes “A New Kind of Science” • In 2004 the company tries to apply the concepts from the book to a real-world product and thus started developing Wolfram Alpha. • In May 18th, 2009 Wolfram Alpha is officially launched to the public
  7. 7. The Working • Users submit queries and computation requests via a text field. • Wolfram Alpha then computes the answers from the curated data. • Wolfram Alpha can only provide robust query results based on computational facts, not queries on the social sciences, cultural studies or even many questions about history where responses require more subtlety and complexity.
  8. 8. What can it do? Here’s a list of what it can do :- → Mathematics → Step-by-Step Solution (PRO) → Statistics & Data Analysis → Units & Measures → Words and Linguistics → People & History → Dates & Time → Data Input (PRO) → Chemistry → Culture & Media → Money & Finance → Image Input (PRO) → Art & Design → Socioeconomic Data → File Upload (PRO) → Astronomy → Health & Medicine → Physics → Engineering → Places & Geography → Food Nutrition → Education → Materials → Earth Sciences → Shopping → Organisations → Life Sciences → Weather & Meteorology → Technological World → Sports & Games → Computational Sciences → Transportation → Music (see here)
  9. 9. THE COMPONENTS • Linguistic analysis • Curated data • Dynamic computation • Computed presentation
  10. 10. The Technology • Wolfram Alpha is written in 15 million lines of Mathematica code and runs on more than 10,000 CPUs. • The database currently includes hundreds of datasets, such as "All Current and Historical Weather". • The curated datasets are checked for quality either by a scientist or other expert in a relevant field.
  11. 11. Licensing Partners Searches in following is powered by Wolfram Alpha : Microsoft Bing DuckDuckGo Engine For factual question answering : Apple’s Siri Samsung’s S Voice Dexetra’s Iris (for Android) Voice Control Software on Blackberry 10.

  14. 14. Wolfram Products
  15. 15. Applications (For Android)
  16. 16. What’s it good for? • Finding facts • Comparisons • Conversions • Solving crossword puzzles • Mathematical Calculations • Presentation of analysed facts
  17. 17. Conclusions • It is all a matter of representing data and mapping queries to the set of things they can compute about. • Uses an internal and pre-structured database to find the answers to the queries. • Computation brings a lot of value when comparing it to search engines like Google. • Little to no information available about how the system works internally.
