| Aspect of history |
| |
| The history of natural language processing describes the advances of |
| natural language processing (Outline of natural language processing). |
| There is some overlap with the history of machine translation, the |
| history of speech recognition, and the history of artificial |
| intelligence. |
| |
| Research and development[edit] |
| |
| The history of machine translation dates back to the seventeenth |
| century, when philosophers such as Leibniz and Descartes put forward |
| proposals for codes which would relate words between languages. All of |
| these proposals remained theoretical, and none resulted in the |
| development of an actual machine. |
| |
| The first patents for "translating machines" were applied for in the |
| mid-1930s. One proposal, by Georges Artsrouni was simply an automatic |
| bilingual dictionary using paper tape. The other proposal, by Peter |
| Troyanskii, a Russian, was more detailed. It included both the |
| bilingual dictionary, and a method for dealing with grammatical roles |
| between languages, based on Esperanto. |
| |
| In 1950, Alan Turing published his famous article "Computing Machinery |
| and Intelligence" which proposed what is now called the Turing test as |
| a criterion of intelligence. This criterion depends on the ability of a |
| computer program to impersonate a human in a real-time written |
| conversation with a human judge, sufficiently well that the judge is |
| unable to distinguish reliably — on the basis of the conversational |
| content alone — between the program and a real human. |
| |
| In 1957, Noam Chomsky’s Syntactic Structures revolutionized Linguistics |
| with 'universal grammar', a rule based system of syntactic |
| structures.^[1] |
| |
| The Georgetown experiment in 1954 involved fully automatic translation |
| of more than sixty Russian sentences into English. The authors claimed |
| that within three or five years, machine translation would be a solved |
| problem.^[2] However, real progress was much slower, and after the |
| ALPAC report in 1966, which found that ten years long research had |
| failed to fulfill the expectations, funding for machine translation was |
| dramatically reduced. Little further research in machine translation |
| was conducted until the late 1980s, when the first statistical machine |
| translation systems were developed. |
| |
| Some notably successful NLP systems developed in the 1960s were SHRDLU, |
| a natural language system working in restricted "blocks worlds" with |
| restricted vocabularies. |
| |
| In 1969 Roger Schank introduced the conceptual dependency theory for |
| natural language understanding.^[3] This model, partially influenced by |
| the work of Sydney Lamb, was extensively used by Schank's students at |
| Yale University, such as Robert Wilensky, Wendy Lehnert, and Janet |
| Kolodner. |
| |
| In 1970, William A. Woods introduced the augmented transition network |
| (ATN) to represent natural language input.^[4] Instead of phrase |
| structure rules ATNs used an equivalent set of finite state automata |
| that were called recursively. ATNs and their more general format called |
| "generalized ATNs" continued to be used for a number of years. During |
| the 1970s many programmers began to write 'conceptual ontologies', |
| which structured real-world information into computer-understandable |
| data. Examples are MARGIE (Schank, 1975), SAM (Cullingford, 1978), PAM |
| (Wilensky, 1978), TaleSpin (Meehan, 1976), QUALM (Lehnert, 1977), |
| Politics (Carbonell, 1979), and Plot Units (Lehnert 1981). During this |
| time, many chatterbots were written including PARRY, Racter, and |
| Jabberwacky. |
| |
| Up to the 1980s, most NLP systems were based on complex sets of |
| hand-written rules. Starting in the late 1980s, however, there was a |
| revolution in NLP with the introduction of machine learning algorithms |
| for language processing. This was due both to the steady increase in |
| computational power resulting from Moore's Law and the gradual |
| lessening of the dominance of Chomskyan theories of linguistics (e.g. |
| transformational grammar), whose theoretical underpinnings discouraged |
| the sort of corpus linguistics that underlies the machine-learning |
| approach to language processing.^[5] Some of the earliest-used machine |
| learning algorithms, such as decision trees, produced systems of hard |
| if-then rules similar to existing hand-written rules. Increasingly, |
| however, research has focused on statistical models, which make soft, |
| probabilistic decisions based on attaching real-valued weights to the |
| features making up the input data. The cache language models upon which |
| many speech recognition systems now rely are examples of such |
| statistical models. Such models are generally more robust when given |
| unfamiliar input, especially input that contains errors (as is very |
| common for real-world data), and produce more reliable results when |
| integrated into a larger system comprising multiple subtasks. |
| |
| Many of the notable early successes occurred in the field of machine |
| translation, due especially to work at IBM Research, where successively |
| more complicated statistical models were developed. These systems were |
| able to take advantage of existing multilingual textual corpora that |
| had been produced by the Parliament of Canada and the European Union as |
| a result of laws calling for the translation of all governmental |
| proceedings into all official languages of the corresponding systems of |
| government. However, most other systems depended on corpora |
| specifically developed for the tasks implemented by these systems, |
| which was (and often continues to be) a major limitation in the success |
| of these systems. As a result, a great deal of research has gone into |
| methods of more effectively learning from limited amounts of data. |
| |
| Recent research has increasingly focused on unsupervised and |
| semi-supervised learning algorithms. Such algorithms are able to learn |
| from data that has not been hand-annotated with the desired answers, or |
| using a combination of annotated and non-annotated data. Generally, |
| this task is much more difficult than supervised learning, and |
| typically produces less accurate results for a given amount of input |
| data. However, there is an enormous amount of non-annotated data |
| available (including, among other things, the entire content of the |
| World Wide Web), which can often make up for the inferior results. |

| cases" that stress the limits of its theoretical models (comparable |
| to pathological phenomena in mathematics), typically created using |
| thought experiments, rather than the systematic investigation of |
| typical phenomena that occur in real-world data, as is the case in |
| corpus linguistics. The creation and use of such corpora of |
| real-world data is a fundamental part of machine-learning |
| algorithms for NLP. In addition, theoretical underpinnings of |
| Chomskyan linguistics such as the so-called "poverty of the |
| stimulus" argument entail that general learning algorithms, as are |
| typically used in machine learning, cannot be successful in |
| language processing. As a result, the Chomskyan paradigm |
| discouraged the application of such models to language processing. |
