Now this Stephen was a doctorate in particle physics at the age of 20.Unlike a search engine which gives a list of documents and website that might contains an answer.But was officially launched on 18 May,2009.
> It works on the code written for mathematica which wolfram research has been using over 25 years.> Almost any workflow involves computing results, and that's what Mathematica does—from building a hedge-fund trading website or publishing interactive engineering textbooks, to developing embedded image-recognition algorithms or teaching calculus
-> It is capable of responding to particularly phrased natural-language fact-based questions such as "Where was Mary Robinson born?" or more complex questions such as "How old was Queen Elizabeth II in 1974?" It displays its "Input interpretation" of such a question, using standardized phrases such as "age | of Queen Elizabeth II (royalty) | in 1974", the answer of which is "Age at start of 1974: 47 years", and a biography link. Wolfram Alpha does not answer queries which require a narrative response such as "What is the difference between the Julian and the Gregorian calendars?" but will answer factual or computational questions such as "June 1 in Julian calendar".
One example of a live dataset that Wolfram Alpha can use is the profile of a Facebook user. If the user authorizes Facebook to share his or her account details with the Wolfram site, Alpha can generate a "personal analytics" report containing the age distribution of friends, the frequency of words used in status updates and other detailed information. Within two weeks of launching the Facebook analytics service, 400,000 users had used it.Downloadable query results are behind a pay wall but summaries are accessible to free accounts.> Topics under development philosophical, products..

Advantages or Usages
• Also written as WolframAlpha or Wolfram|Alpha.
• It is a computational knowledge engine or answer
• It was released on 15th May 2009.
• It answers factual queries by computing the answers
for “externally sourced curated data”.
• It is mostly based on wolfram’s earlier product
• Mathematica a computational toolkit that
encompasses computer algebra, symbolic and
numerical computation, visualization, and statistics
• 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
Project lead by
It is the culmination
of 5 years of work,
and 25 more years
in 1987, focusing
mainly on the
• 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
• 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
What can it do?

• Dynamic computation
• Computed presentation
• Wolfram Alpha is written in 15 million lines of
Mathematica code and runs on more than
• The database currently includes hundreds of
datasets, such as "All Current and Historical
• The curated datasets are checked for quality
either by a scientist or other expert in a

For factual question answering :
Samsung’s S Voice
Dexetra’s Iris (for Android)
Voice Control Software on Blackberry 10.
What’s it good for?
• Finding facts
• Solving crossword puzzles
• Mathematical Calculations
• Presentation of analysed facts
• 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
