Some wireless operators have even started free sign language gateways. Sign language interpretation services via VRS or by VRI are useful in the present day where one of the parties is deaf, hard-of-hearing, or speech-impaired mute. In such cases the interpretation flow is normally within the same principal language, such as French Sign Language LSF to spoken French, Spanish Sign Language LSE to spoken Spanish, British Sign Language BSL to spoken English, and American Sign Language ASL also to spoken English since BSL and ASL are completely distinct from each otherGerman Sign Language DGS to spoken German, and so on.
Multilingual sign language interpreters, who can also translate as well across principal languages such as a multilingual interpreter interpreting a call from a deaf person using ASL to reserve a hotel room at a hotel in the Dominican Republic whose staff speaks Spanish only, therefore the interpreter has to utilize ASL, spoken Spanish, and spoken English to facilitate the call for the deaf personare also available, albeit less frequently.
With video interpreting, sign language interpreters work remotely with live video and audio feeds, so that the interpreter can see the deaf or mute party, and converse with the hearing party, and vice versa. Favourable reviews quickly led to its popular usage at educational facilities for the deaf, and from there to the greater deaf community.
Much like telephone interpreting, video interpreting can be used for situations in which no on-site interpreters are available. However, video interpreting cannot be used for situations in which all parties are speaking via telephone alone. VRS and VRI interpretation requires all parties to have the necessary equipment. Some advanced equipment enables interpreters to control the video camera remotely, in order to zoom in and out or to point the camera toward the party that is signing.
The name videophone never became as standardized as its earlier counterpart telephoneresulting in a variety of names and terms being used worldwide, and even within the same region or country. Videophones are also known as video phonesvideotelephones or video telephones and often by an early trademarked name Picturephonewhich was the world s first commercial videophone produced in volume. The compound name videophone slowly entered into general use after 1950, 81 although video telephone likely entered the lexicon earlier after video was coined in 1935.
Such activities involve considerable mental processing efforts on the part of the translator, since sign languages are distinct natural languages with their own construction, semantics and syntax, different from the aural version of the same principal language. Videophone calls also videocallsvideo chat 83 as well as Skype and Skyping in verb form 84 differ from videoconferencing in that they expect to serve individuals, not groups.
In general everyday usage the term videoconferencing is now frequently used instead of videocall for point-to-point calls between two units. Both videophone calls and videoconferencing are also now commonly referred to as a video link. 2 However that distinction has become increasingly blurred with technology improvements such as increased bandwidth and sophisticated software clients that can allow for multiple parties on a call.
A videoconference system is generally higher cost than a videophone and deploys greater capabilities. A videoconference also known as a videoteleconference allows two or more locations to communicate via live, simultaneous two-way video and audio transmissions. Again, technology improvements have circumvented traditional definitions by allowing multiple party videoconferencing via web-based applications.
A telepresence system is a high-end videoconferencing system and service usually employed by enterprise-level corporate offices. This is often accomplished by the use of a multipoint control unit a centralized distribution and call management system or by a similar non-centralized multipoint capability embedded in each videoconferencing unit. Telepresence conference rooms use state-of-the art room designs, video cameras, displays, sound-systems and processors, coupled with high-to-very-high capacity bandwidth transmissions.
Typical use of the various technologies described above include calling or conferencing on a one-on-one, one-to-many or many-to-many basis for personal, business, educational, deaf Video Relay Service and tele-medical, diagnostic and rehabilitative use or services. New services utilizing videocalling and videoconferencing, such as teachers and psychologists conducting online sessions, 87 personal videocalls to inmates incarcerated in penitentiaries, and videoconferencing to resolve airline engineering issues at maintenance facilities, are being created or evolving on an ongoing basis.
A telepresence robot also telerobotics is a robotically controlled and motorized video conferencing display to help give a better sense of remote physical presence for communication and collaboration in an office, home, school, etc. when one cannot be there in person. The robotic avatar device can move about and look around at the command of the remote person it represents. In science fiction literature, names commonly associated with videophones include telephonoscopetelephoteviewphonevidphonevidfoneand visiphone.
The first example was probably the cartoon Edison s Telephonoscope by George du Maurier in Punch 1878. 90 In many science fiction movies and TV programs that are set in the future, videophones were used as a primary method of communication. Latin-based translations of videophone in other languages include vidéophone FrenchBildtelefon Germanvideotelefono Italianboth videófono and videoteléfono Spanishboth beeldtelefoon and videofoon Dutchand videofonía Catalan.
One of the first movies where a videophone was used was Fritz Lang s Metropolis 1927. Other notable examples of videophones in popular culture include an iconic scene from the 1968 film 2001 A Space Odyssey set on Space Station V. The movie was released shortly before AT T began its efforts to commercialize its Picturephone Mod II service in several cities and depicts a videocall to Earth using an advanced AT T videophone which it predicts will cost 1. 70 for a two-minute call in 2001 a fraction of the company s real rates on Earth in 1968.
Film director Stanley Kubrick strove for scientific accuracy, relying on interviews with scientists and engineers at Bell Labs in the United States. Larry Rabiner of Bell Labs, discussing videophone research in the documentary 2001 The Making of a Mythstated that in the mid- to late-1960s videophones.
captured the imagination of the public and. Kubrick and the people who reported to him. In one 2001 movie scene a central character, Dr. Heywood Floyd, calls home to contact his family, a social feature noted in the Making of a Myth. Floyd talks with and views his daughter from a space station in orbit above the Earth, discussing what type of present he should bring home for her.
92 unreliable source 93 94. A portable videophone is also featured prominently in the 2009 science fiction movie Moonwhere the story s protagonist, Sam Bell, also calls home as well to communicate with loved ones. Bell, the lone occupant of a mining station on the far side of the Earth s moon, finally succeeds in making his videocall after an extended work period, but becomes traumatized when viewing his daughter. Other earlier examples of videophones in popular culture included a videophone that was featured in the Warner Bros.
cartoon, Plane Daffyin which the female spy Hatta Mari used a videophone to communicate with Adolf Hitler 1944as well as a device with the same functionality has been used by the comic strip character Dick Tracywho often used his 2-way wrist TV to communicate with police headquarters. 96 1964 1977. By the early 2010s videotelephony and videophones had become commonplace and unremarkable in various forms of media, in part due to their real and ubiquitous presence in common electronic devices and laptop computers.
Additionally, TV programming increasingly utilized videophones to interview subjects of interest and to present live coverage by news correspondents, via the Internet or by satellite links. In the mass market media, the popular U. TV talk show hostess Oprah Winfrey incorporated videotelephony into her TV program on a regular basis from May 21, 2009, with an initial episode called Where the Skype Are You.as part of a marketing agreement with the Internet telecommunication company Skype. Additionally, videophones have been featured in.
Lisa s Weddingan episode of The Simpsons which depicted a Picturephone 1995. Other names for videophone that have been used in English are Viewphone the British Telecom equivalent to AT T s Picturephone88 and visiophonea common French translation that has also crept into limited English usage, as well as over twenty less common names and expressions. 99 a Beyoncé Knowles pop single and music video called Video Phone from her album I am.

Watson is a question-answering computer system capable of answering questions posed in natural language, 2 developed in IBM s DeepQA project by a research team led by principal investigator David Ferrucci.
against champions Brad Rutter and Ken Jennings, 4 7 winning the first place prize of 1 million. 6 and, in 2011, the Watson computer system competed on Jeopardy. In February 2013, IBM announced that Watson software system s first commercial application would be for utilization management decisions in lung cancer treatment at Memorial Sloan Kettering Cancer Center, New York City, in conjunction with WellPoint now Anthem.
9 In 2013, Manoj Saxena, IBM Watson s business chief said that 90 of nurses in the field who use Watson now follow its guidance. 1 Description 1.

The computer system was initially developed to answer questions on the quiz show Jeopardy. 9 Advertising 5 See also 6 References 7 Further reading 8 External links 8. 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 rankingwhile 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.
8 Tax preparation 4. When created, IBM stated that, more than 100 different techniques are used to analyze natural language, identify sources, find and generate hypotheses, find and score evidence, and merge and rank hypotheses. In recent years, the Watson capabilities have been extended and the way in which Watson works has been changed to take advantage of new deployment models Watson on IBM Cloud and evolved machine learning capabilities and optimised hardware available to developers and researchers.
It is no longer purely a question answering QA computing system designed from Q A pairs but can now seehearreadtalktasteinterpretlearn and recommend. The system was written in various languages, including Java, Cand Prolog, and runs on the SUSE Linux Enterprise Server 11 operating system using the Apache Hadoop framework to provide distributed computing.
2 Watson employs a cluster of ninety IBM Power 750 servers, each of which uses a 3. 5 GHz POWER7 eight-core processor, with four threads per core. According to John Rennie, Watson can process 500 gigabytes, the equivalent of a million books, per second. 18 IBM s master inventor and senior consultant, Tony Pearson, estimated Watson s hardware cost at about iqoption portugues million dollars.
In total, the system has 2,880 POWER7 processor threads and 16 terabytes of RAM. 20 According to Rennie, all content was stored in Watson s 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 including DBPedia, WordNet and Yago. 21 The IBM team provided Watson with millions of documents, including dictionaries, encyclopedias and other reference material that it could use to build its knowledge. clues sounded just like mine. That machine zeroes in on keywords in a clue then combs its memory in Watson s case, a 15-terabyte databank of human knowledge for clusters of associations with those words.
The computer s techniques for unravelling Jeopardy. And when it feels sure enough, it decides to buzz. This is all an instant, intuitive process for a human Jeopardy. player, but I felt convinced that under the hood my brain was doing more or less the same thing. 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.
Watson parses questions into different keywords and sentence fragments in order to find statistically related phrases. 22 Watson s 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. 22 24 The more algorithms that find the same answer independently the more likely Watson is to be correct.
22 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 players Edit. Watson s 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.
25 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. 22 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. 22 Watson s programming prevents it from using the popular tactic of buzzing before it is sure of its response.
In a sequence of 20 mock games of Jeopardyhuman 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. 22 During that time, Watson also has to evaluate the response and determine whether it is sufficiently confident in the result to signal. 22 Part of the system used to win the Jeopardy. contest was the electronic circuitry that receives the ready signal and then examined whether Watson s confidence level was great enough to activate the buzzer.
Given the speed of this circuitry compared to the speed of human reaction times, Watson s reaction time was faster than the human contestants except when the human anticipated instead of reacted to the ready signal. s question format. 22 Watson s voice was synthesized from recordings that actor Jeff Woodman made for an IBM text-to-speech program in 2004. The Jeopardy. staff used different means to notify Watson and the human players when to buzz, 27 which was critical in many rounds.
26 The humans were notified by a light, which took them tenths of a second to perceive. 29 30 Watson was notified by an electronic signal and could activate the buzzer within about eight milliseconds. 31 The humans tried to compensate for the perception delay by anticipating the light, 32 but the variation in the anticipation time was generally too great to fall within Watson s response time.
26 Watson did not attempt to anticipate the notification signal. Since Deep Blue s victory over Garry Kasparov in chess in 1997, IBM had been on the hunt for a new challenge. 27 After signaling, Watson speaks with an electronic voice and gives the responses in Jeopardy. In 2004, 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 74-game run on Jeopardy.
Nearly the entire restaurant had piled toward the televisions, mid-meal, to watch Jeopardy. Intrigued by the quiz show as a possible challenge for IBM, Lickel passed the idea on, and in 2005, IBM Research executive Paul Horn supported Lickel, pushing for someone in his department to take up the challenge of playing Jeopardy. with an IBM system. 19 Its Linpack performance stands at 80 TeraFLOPs, which is about half as fast as the cut-off line for the Top 500 Supercomputers list.
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. 33 In competitions managed by the United States government, Watson s predecessor, a system named Piquant, was usually able to respond correctly to only about 35 of clues and often required several minutes to respond.Watson would need to respond in no more than a few seconds, and at that time, the problems posed by the game show were deemed to be impossible to solve.
In initial tests run during 2006 by David Ferrucci, the senior manager of IBM s Semantic Analysis and Integration department, Watson was given 500 clues from past Jeopardy. While the best real-life competitors buzzed in half the time and responded correctly to as many as 95 of clues, Watson s first pass could get only about 15 correct. During 2007, the IBM team was given three to five years and a staff of 15 people to solve the problems. Kelly III succeeded Paul Horn as head of IBM Research in 2007.
37 InformationWeek described Kelly as the father of Watson and credited him for encouraging the system to compete against humans on Jeopardy. 34 35 36 To compete successfully on Jeopardy. 22 By February 2010, Watson could beat human Jeopardy. 38 By 2008, the developers had advanced Watson such that it could compete with Jeopardy. contestants on a regular basis.
During the game, Watson had access to 200 million pages of structured and unstructured content consuming four terabytes of disk storage 14 including the full text of the 2011 edition of Wikipedia, 40 but was not connected to the Internet. 41 22 For each clue, Watson s three most probable responses were displayed on the television screen. Watson consistently outperformed its human opponents on the game s signaling device, but had trouble in a few categories, notably those having short clues containing only a few words.
In 2008, IBM representatives communicated with Jeopardy. executive producer Harry Friedman about the possibility of having Watson compete against Ken Jennings and Brad Rutter, two of the most successful contestants on the show, and the program s producers agreed. 22 43 Watson s differences with human players had generated conflicts between IBM and Jeopardy. The system is workload-optimized, integrating massively parallel POWER7 processors and built on IBM s DeepQA technology, 17 which it uses to generate hypotheses, gather massive evidence, and analyze data.
staff during the planning of the competition. 25 IBM repeatedly expressed concerns that the show s writers would exploit Watson s cognitive deficiencies when writing the clues, thereby turning iqoption portugues game into a Turing test. To alleviate that claim, a third party randomly picked the clues from previously written shows that were never broadcast. 25 Jeopardy. staff also showed concerns over Watson s reaction time on the buzzer.
Originally Watson signalled electronically, but show staff requested that it press a button physically, as the human contestants would. 44 Even with a robotic finger pressing the buzzer, Watson remained faster than its human competitors. Ken Jennings noted, If you re trying to win on the show, the buzzer is alland that Watson can knock out a microsecond-precise buzz every single time with little or no variation.
Human reflexes can t compete with computer circuits in this regard. 26 32 45 Stephen Baker, a journalist who recorded Watson s development in his book Final Jeopardyreported that the conflict between IBM and Jeopardy. became so serious in May 2010 that the competition was almost canceled. Human players, including former Jeopardy. 25 As part of the preparation, IBM constructed a mock set in a conference room at one of its technology sites to model the one used on Jeopardy.
contestants, also participated in mock games against Watson with Todd Alan Crain of The Onion playing host. 22 About 100 test matches were conducted with Watson winning 65 of the games. To provide a physical presence in the televised games, Watson was represented by an avatar of a globe, inspired by the IBM smarter planet symbol. Jennings described the computer s avatar as a glowing blue ball criss-crossed by threads of thought 42 threads, to be precise23 and stated that the number of thought threads in the avatar was an in-joke referencing the significance of the number 42 in Douglas Adams Hitchhiker s Guide to the Galaxy.
A practice match was recorded on January 13, 2011, and the official matches were recorded on January 14, 2011. 23 Joshua Davis, the artist who designed the avatar for the project, explained to Stephen Baker that there are 36 triggerable states that Watson was able to use throughout the game to show its confidence in responding to a clue correctly; he had hoped to be able to find forty-two, to add another level to the Hitchhiker s Guide reference, but he was unable to pinpoint enough game states.
Practice match Edit. All participants maintained secrecy about the outcome until the match was broadcast in February. In a practice match before the press on January 13, 2011, Watson won a 15-question round against Ken Jennings and Brad Rutter with a score of 4,400 to Jennings s 3,400 and Rutter s 1,200, though Jennings and Watson were tied before the final 1,000 question. First match Edit. None of the three players responded incorrectly to a clue. The first round was broadcast February 14, 2011, and the second round, on February 15, 2011.
The right to choose the first category had been determined by a draw won by Rutter. 50 Watson, represented by a computer monitor display and artificial voice, responded correctly to the second clue and then selected the fourth clue of the first category, a deliberate strategy to find the Daily Double as quickly as possible. 51 Watson s guess at the Daily Double location was correct. At the end of the first round, Watson was tied with Rutter at 5,000; Jennings had 2,000.
Watson s performance was characterized by some quirks. In one instance, Watson repeated a reworded version of an incorrect response offered by Jennings. Jennings said What are the 20s. in reference to the 1920s. Then Watson said What is 1920s. Because Watson could not recognize other contestants responses, it did not know that Jennings had already given the same response. after Jennings incorrectly responded What is he only had one hand. In another instance, Watson was initially given credit for a response of What is a leg.
to a clue about George Eyser the correct response was, What is he s missing a leg. Because Watson, unlike a human, could not have been responding to Jennings s mistake, it was decided that this response was incorrect. 52 Watson also demonstrated complex wagering strategies on the Daily Doubles, with one bet at 6,435 and another at 1,246. 53 Gerald Tesauro, one of the IBM researchers who worked on Watson, explained that Watson s wagers were based on its confidence level for the category and a complex regression model called the Game State Evaluator.
Watson took a commanding lead in Double Jeopardy.correctly responding to both Daily Doubles. Watson responded to the second Daily Double correctly with a 32 confidence score. However during the Final Jeopardy. The broadcast version of the episode was edited to omit Trebek s original acceptance of Watson s response. round, Watson was the only contestant to miss the clue in the category U. Cities Its largest airport was named for a World War II hero; its second largest, for a World War II battle.
Rutter and Jennings gave the correct response of Chicago, but Watson s response was What is Toronto. 53 55 56 Ferrucci offered reasons why Watson would appear to have guessed a Canadian city categories only weakly suggest the type of response desired, the phrase U. with five question marks appended indicating a lack of confidence. city did not appear in the question, there are cities named Toronto in the U.and Toronto in Ontario has an American League baseball team.
Chris Welty, who also worked on Watson, suggested that it may not have been able to correctly parse the second part of the clue, its second largest, for a World War II battle which was not a standalone clause despite it following a semicolon, and required context to understand that it was referring to a second-largest airport.
58 Eric Nyberg, a professor at Carnegie Mellon University and a member of the development team, stated that the error occurred because Watson does not possess the comparative knowledge to discard that potential response as not viable. 56 Although not displayed to the audience as with non-Final Jeopardy. questions, Watson s second choice was Chicago. Watson wagered only 947 on the question. The game ended with Jennings with 4,800, Rutter with 10,400, and Watson with 35,734.
Second match Edit. During the introduction, Trebek a Canadian native joked that he had learned Toronto was a U. city, and Watson s error in the first match prompted an IBM engineer to wear a Toronto Blue Jays jacket to the recording of the second match. In the first round, Jennings was finally able to choose a Daily Double clue, 60 while Watson responded to one Daily Double clue incorrectly for the first time in the Double Jeopardy. 61 After the first round, Watson placed second for the first time in the competition after Rutter and Jennings were briefly successful in increasing their dollar values before Watson could respond.
61 62 Nonetheless, the final result ended with a victory for Watson with a score of 77,147, besting Jennings who scored 24,000 and Rutter who scored 21,600. Final outcome Edit. The prizes for the competition were 1 million for first place Watson300,000 for second place Jenningsand 200,000 for third place Rutter. As promised, IBM donated 100 of Watson s winnings to charity, with 50 of those winnings going to World Vision and 50 going to World Community Grid. 64 Similarly, Jennings and Rutter donated 50 of their winnings to their respective charities.
In acknowledgment of IBM and Watson s achievements, Jennings made an additional remark in his Final Jeopardy. response I for one welcome our new computer overlordsechoing a similar meme to the episode Deep Space Homer on The Simpsonsin which TV news presenter Kent Brockman speaks of welcoming our new insect overlords. 66 67 Jennings later wrote an article for Slatein which he stated. IBM has bragged to the media that Watson s question-answering skills are good for more than annoying Alex Trebek.
The company sees a future in which fields like medical diagnosis, business analytics, and tech support are automated by question-answering iqoption portugues like Watson. Just as factory jobs were eliminated in the 20th century by new assembly-line robots, Brad and I were the first knowledge-industry workers put out of work by the new generation of thinking machines. Quiz show contestant may be the first job made redundant by Watson, but I m sure it won t be the last. Philosopher John Searle argues that Watson despite impressive capabilities cannot actually think.
68 Drawing on his Chinese room thought experiment, Searle claims that Watson, like other computational machines, is capable only of manipulating symbols, but has no ability to understand the meaning of those symbols; however, Searle s experiment has its detractors. Match against members of the United States Congress Edit. On February 28, 2011, Watson played an untelevised exhibition match of Jeopardy. against members of the United States House of Representatives.
In the first round, Rush D. D-NJ, a former Jeopardy. contestantwho was challenging the computer with Bill Cassidy R-LA, later Senator from Louisianaled with Watson in second place. However, combining the scores between all matches, the final score was 40,300 for Watson and 30,000 for the congressional players combined. IBM s Christopher Padilla said of the match, The technology behind Watson represents a major advancement in computing. In the data-intensive environment of government, this type of technology can help organizations make better decisions and improve how government helps its citizens.
According to IBM, The goal is to have computers start to interact in natural human terms across a range of applications and processes, understanding the questions that humans ask and providing answers that humans can understand and justify. 39 It has been suggested by Robert C. Weber, IBM s general counsel, that Watson may be used for legal research. 71 The company also intends to use Watson iqoption portugues other information-intensive fields, such as telecommunications, financial services, and government.
Watson is based on commercially available IBM Power 750 servers that have been marketed since February 2010. IBM also intends to market the DeepQA software to large corporations, with a price in the millions of dollars, reflecting the 1 million needed to acquire a server that meets the minimum system requirement to operate Watson. IBM expects the price to decrease substantially within a decade as the technology improves.
Commentator Rick Merritt said that there s another really important reason why it is strategic for IBM to be seen very broadly by the American public as a company that can tackle tough computer problems. A big slice of IBM s profit comes from selling to the U. government some of the biggest, most expensive systems in the world.
In 2013, it was reported that three companies were working with IBM to create apps embedded with Watson technology. Fluid is developing an app for retailers, one called The North Facewhich is designed to provide advice to online shoppers. Welltok is developing an app designed to give people advice on ways to engage in activities to improve their health.
