Watson is a question answering QA computing system that IBM built to apply advanced natural language processing, information retrieval, knowledge representation, automated reasoning, and machine learning technologies to the field of open domain question answering. The key difference between QA technology and document search is that document search takes a keyword query and returns a list of documents, ranked in order of relevance to the query often based on popularity and page ranking, while QA technology takes a question expressed in natural language, seeks to understand it in much greater detail, and returns a precise answer to the question. According to IBM, more than 1. SoftwareeditWatson uses IBMs Deep. QA software and the Apache UIMA Unstructured Information Management Architecture framework. The system was written in various languages, including Java, C, and Prolog, and runs on the SUSE Linux Enterprise Server 1. Apache Hadoop framework to provide distributed computing. HardwareeditThe system is workload optimized, integrating massively parallel. POWER7 processors and built on IBMs Deep. QA technology,2. Watson employs a cluster of ninety IBM Power 7. GHz POWER7 eight core processor, with four threads per core. In total, the system has 2,8. POWER7 processor threads and 1. Watch Little Malcolm Online Hoyts. RAM. 2. 0According to John Rennie, Watson can process 5. IBMs master inventor and senior consultant, Tony Pearson, estimated Watsons hardware cost at about three million dollars. Its Linpack performance stands at 8. Tera. FLOPs, which is about half as fast as the cut off line for the Top 5. Supercomputers list. According to Rennie, all content was stored in Watsons RAM for the Jeopardy game because data stored on hard drives would be too slow to be competitive with human Jeopardy champions. The sources of information for Watson include encyclopedias, dictionaries, thesauri, newswire articles, and literary works. Watson also used databases, taxonomies, and ontologies. Specifically, DBPedia, Word. Net, and Yago were used. The IBM team provided Watson with millions of documents, including dictionaries, encyclopedias, and other reference material that it could use to build its knowledge. OperationeditThe computers techniques for unraveling Jeopardy That machine zeroes in on key words in a clue, then combs its memory in Watsons case, a 1. It rigorously checks the top hits against all the contextual information it can muster the category name the kind of answer being sought the time, place, and gender hinted at in the clue and so on. And when it feels sure enough, it decides to buzz. This is all an instant, intuitive process for a human Jeopardy I felt convinced that under the hood my brain was doing more or less the same thing. Ken Jennings2. Watson parses questions into different keywords and sentence fragments in order to find statistically related phrases. Watsons main innovation was not in the creation of a new algorithm for this operation but rather its ability to quickly execute hundreds of proven language analysis algorithms simultaneously. The more algorithms that find the same answer independently the more likely Watson is to be correct. Once Watson has a small number of potential solutions, it is able to check against its database to ascertain whether the solution makes sense or not. Comparison with human playerseditWatsons basic working principle is to parse keywords in a clue while searching for related terms as responses. This gives Watson some advantages and disadvantages compared with human Jeopardy Watson has deficiencies in understanding the contexts of the clues. As a result, human players usually generate responses faster than Watson, especially to short clues. Watsons programming prevents it from using the popular tactic of buzzing before it is sure of its response. Watson has consistently better reaction time on the buzzer once it has generated a response, and is immune to human players psychological tactics, such as jumping between categories on every clue. In a sequence of 2. Jeopardy, human participants were able to use the average six to seven seconds that Watson needed to hear the clue and decide whether to signal for responding. During that time, Watson also has to evaluate the response and determine whether it is sufficiently confident in the result to signal. Part of the system used to win the Jeopardy Watsons confidence level was great enough to activate the buzzer. Given the speed of this circuitry compared to the speed of human reaction times, Watsons reaction time was faster than the human contestants except when the human anticipated instead of reacted to the ready signal. After signaling, Watson speaks with an electronic voice and gives the responses in Jeopardys question format. Watsons voice was synthesized from recordings that actor Jeff Woodman made for an IBM text to speech program in 2. The Jeopardy staff used different means to notify Watson and the human players when to buzz,2. The humans were notified by a light, which took them tenths of a second to perceive. Watson was notified by an electronic signal and could activate the buzzer within about eight milliseconds. The humans tried to compensate for the perception delay by anticipating the light,3. Watsons response time. Watson did not attempt to anticipate the notification signal. HistoryeditDevelopmenteditSince Deep Blues victory over Garry Kasparov in chess in 1. IBM had been on the hunt for a new challenge. In 2. 00. 4, IBM Research manager Charles Lickel, over dinner with coworkers, noticed that the restaurant they were in had fallen silent. He soon discovered the cause of this evening hiatus Ken Jennings, who was then in the middle of his successful 7. Jeopardy Nearly the entire restaurant had piled toward the televisions, mid meal, to watch the phenomenon. Intrigued by the quiz show as a possible challenge for IBM, Lickel passed the idea on, and in 2. IBM Research executive Paul Horn backed Lickel up, pushing for someone in his department to take up the challenge of playing Jeopardy IBM system. Though he initially had trouble finding any research staff willing to take on what looked to be a much more complex challenge than the wordless game of chess, eventually David Ferrucci took him up on the offer. In competitions managed by the United States government, Watsons predecessor, a system named Piquant, was usually able to respond correctly to only about 3.
