ELIZA
ELIZA is an early natural language processing computer program developed from 1964 to 1967 at MIT by Joseph Weizenbaum. Created to explore communication between humans and machines, ELIZA simulated conversation by using a pattern matching and substitution methodology that gave users an illusion of understanding on the part of the program, but had no representation that could be considered really understanding what was being said by either party. Whereas the ELIZA program itself was written (originally) in MAD-SLIP, the pattern matching directives that contained most of its language capability were provided in separate "scripts", represented in a lisp-like representation. The most famous script, DOCTOR, simulated a psychotherapist of the Rogerian school (in which the therapist often reflects back the patient's words to the patient), and used rules, dictated in the script, to respond with non-directional questions to user inputs. As such, ELIZA was one of the first chatterbots ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
ELIZA Effect
In computer science, the ELIZA effect is a tendency to project human traits — such as experience, semantic comprehension or empathy — onto rudimentary computer programs having a textual interface. ELIZA was a symbolic AI chatbot developed in 1966 by Joseph Weizenbaum and imitating a psychotherapist. Many early users were convinced of ELIZA's intelligence and understanding, despite its basic text-processing approach and the explanations of its limitations. History The effect is named for ELIZA, the 1966 chatbot developed by MIT computer scientist Joseph Weizenbaum. When executing Weizenbaum's ''DOCTOR'' script, ELIZA simulated a Rogerian psychotherapist, largely by rephrasing the "patients replies as questions: : Human: Well, my boyfriend made me come here. : ELIZA: Your boyfriend made you come here? : Human: He says I'm depressed much of the time. : ELIZA: I am sorry to hear you are depressed. : Human: It's true. I'm unhappy. : ELIZA: Do you think coming here will help you ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Chatterbot
A chatbot (originally chatterbot) is a software application or web interface designed to have textual or spoken conversations. Modern chatbots are typically online and use generative artificial intelligence systems that are capable of maintaining a conversation with a user in natural language and simulating the way a human would behave as a conversational partner. Such chatbots often use deep learning and natural language processing, but simpler chatbots have existed for decades. Although chatbots have existed since the late 1960s, the field gained widespread attention in the early 2020s due to the popularity of OpenAI's ChatGPT, followed by alternatives such as Microsoft's Copilot, DeepSeek and Google's Gemini. Such examples reflect the recent practice of basing such products upon broad foundational large language models, such as GPT-4 or the Gemini language model, that get fine-tuned so as to target specific tasks or applications (i.e., simulating human conversation, ...

Joseph Weizenbaum
Joseph Weizenbaum (8 January 1923 – 5 March 2008) was a German-American computer scientist and a professor at Massachusetts Institute of Technology, MIT. He is the namesake of the Weizenbaum Award and the Weizenbaum Institute. Life and career Born in Berlin, Germany to Jewish parents, he escaped Nazi Germany in January 1936, immigrating with his family to the United States. He started studying mathematics in 1941 at Wayne State University, in Detroit, Michigan. In 1942, he interrupted his studies to serve in the United States Army Air Corps, U.S. Army Air Corps as a meteorologist, having been turned down for cryptology work because of his "enemy alien" status. After the war, in 1946, he returned to Wayne State, obtaining his B.S. in Mathematics in 1948, and his M.S. in 1950. Around 1952, as a research assistant at Wayne, Weizenbaum worked on analog computers and helped create a digital computer. In 1956, he worked for General Electric on Electronic Recording Machine, Accounting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Turing Test
The Turing test, originally called the imitation game by Alan Turing in 1949,. Turing wrote about the ‘imitation game’ centrally and extensively throughout his 1950 text, but apparently retired the term thereafter. He referred to ‘ istest’ four times—three times in pp. 446–447 and once on p. 454. He also referred to it as an ‘experiment’—once on p. 436, twice on p. 455, and twice again on p. 457—and used the term ‘viva voce’ (p. 446). See also #Versions, below. Turing gives a more precise version of the question later in the paper: " ese questions reequivalent to this, 'Let us fix our attention on one particular digital computer C. Is it true that by modifying this computer to have an adequate storage, suitably increasing its speed of action, and providing it with an appropriate programme, C can be made to play satisfactorily the part of A in the imitation game, the part of B being taken by a man? is a test of a machine's ability to exhibit intellige ...

Natural-language Understanding
Natural language understanding (NLU) or natural language interpretation (NLI) is a subset of natural language processing in artificial intelligence that deals with machine reading comprehension. NLU has been considered an AI-hard problem. There is considerable commercial interest in the field because of its application to automated reasoning, machine translation, question answering, news-gathering, text categorization, voice-activation, archiving, and large-scale content analysis. History The program STUDENT, written in 1964 by Daniel Bobrow for his PhD dissertation at MIT, is one of the earliest known attempts at NLU by a computer. Eight years after John McCarthy coined the term artificial intelligence, Bobrow's dissertation (titled ''Natural Language Input for a Computer Problem Solving System'') showed how a computer could understand simple natural language input to solve algebra word problems. A year later, in 1965, Joseph Weizenbaum at MIT wrote ELIZA, an interact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Natural Language Processing
Natural language processing (NLP) is a subfield of computer science and especially artificial intelligence. It is primarily concerned with providing computers with the ability to process data encoded in natural language and is thus closely related to information retrieval, knowledge representation and computational linguistics, a subfield of linguistics. Major tasks in natural language processing are speech recognition, text classification, natural-language understanding, natural language understanding, and natural language generation. History Natural language processing has its roots in the 1950s. Already in 1950, Alan Turing published an article titled "Computing Machinery and Intelligence" which proposed what is now called the Turing test as a criterion of intelligence, though at the time that was not articulated as a problem separate from artificial intelligence. The proposed test includes a task that involves the automated interpretation and generation of natural language ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
SLIP (programming Language)
SLIP is a list processing computer programming language, invented by Joseph Weizenbaum in the 1960s. The name ''SLIP'' stands for Symmetric LIst Processor. It was first implemented as an extension to the Fortran programming language, and later embedded into MAD and ALGOL. The best known program written in the language is ELIZA, an early natural language processing computer program A computer program is a sequence or set of instructions in a programming language for a computer to Execution (computing), execute. It is one component of software, which also includes software documentation, documentation and other intangibl ... created by Weizenbaum at the MIT Artificial Intelligence Laboratory. General overview In a nutshell, SLIP consisted of a set of FORTRAN "accessor" functions which operated on circular doubly linked lists with fixed-size data fields. The "accessor" functions had direct and indirect addressing variants. List representation The list represent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Eliza Doolittle
Eliza Doolittle is a fictional character and the protagonist in George Bernard Shaw's play '' Pygmalion'' (1913) and its 1956 musical adaptation, ''My Fair Lady''. Eliza (from Lisson Grove, London) is a Cockney flower seller, who comes to Professor Henry Higgins asking for elocution lessons, after a chance encounter at Covent Garden. Higgins goes along with it for the purposes of a wager: That he can turn her into the toast of elite London society. Her Cockney dialect includes words that are common among working class Londoners, such as ain't; "I ain't done nothing wrong by speaking to the gentleman" said Doolittle. Doolittle receives voice coaching and learns the rules of etiquette. The outcome of these attentions varies between the original play and the various adaptations (see '' Pygmalion''). History The character of Eliza Doolittle was likely inspired by the real story of Eliza Sheffield (1856–1942), a barmaid in London who rose through the ranks of society in the la ...

Rogerian Psychotherapy
Person-centered therapy (PCT), also known as person-centered psychotherapy, person-centered counseling, client-centered therapy and Rogerian psychotherapy, is a humanistic approach psychotherapy developed by psychologist Carl Rogers and colleagues beginning in the 1940s and extending into the 1980s. Person-centered therapy emphasizes the importance of creating a therapeutic environment grounded in three core conditions: unconditional positive regard (acceptance), congruence (genuineness), and empathic understanding. It seeks to facilitate a client's actualizing tendency, "an inbuilt proclivity toward growth and fulfillment", via acceptance ('' unconditional positive regard''), therapist ''congruence'' (genuineness), and empathic understanding. History and influences Person-centered therapy was developed by Carl Rogers in the 1940s and 1950s, and was brought to public awareness largely through his book ''Client-centered Therapy'', published in 1951. It has been recognized as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Compatible Time-Sharing System
The Compatible Time-Sharing System (CTSS) was the first general purpose time-sharing operating system. Compatible Time Sharing referred to time sharing which was compatible with batch processing; it could offer both time sharing and batch processing concurrently. CTSS was developed at the MIT Computation Center ("Comp Center"). CTSS was first demonstrated on MIT's modified IBM 709 in November 1961. The hardware was replaced with a modified IBM 7090 in 1962 and later a modified IBM 7094 called the "blue machine" to distinguish it from the Project MAC CTSS IBM 7094. Routine service to MIT Comp Center users began in the summer of 1963 and was operated there until 1968. A second deployment of CTSS on a separate IBM 7094 that was received in October 1963 (the "red machine") was used early on in Project MAC until 1969 when the red machine was moved to the Information Processing Center and operated until July 20, 1973. CTSS ran on only those two machines; however, there were remot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Pygmalion (play)
''Pygmalion'' is a play by Irish playwright George Bernard Shaw, named after the Pygmalion (mythology), Greek mythological figure. It premiered at the Burgtheater, Hofburg Theatre in Vienna on 16 October 1913 and was first presented on stage in German. Its English-language premiere took place at Her Majesty's Theatre, His Majesty's Theatre in London's West End theatre, West End in April 1914 and starred Herbert Beerbohm Tree as phonetics professor Henry Higgins and Mrs Patrick Campbell as Cockney flower-girl Eliza Doolittle. Inspiration In ancient Greek mythology, Pygmalion (mythology), Pygmalion fell in love with one of his sculptures, which then came to life. The general idea of that myth was a popular subject for Victorian era British playwrights, including one of Shaw's influences, W. S. Gilbert, who wrote a successful play based on the story called ''Pygmalion and Galatea (play), Pygmalion and Galatea'' that was first presented in 1871. Shaw would also have been familiar ...
