Computational Linguistics
CL-2
most notable features of modern linguistics is the new collaboration
between linguists and computer wizards
These recent collaboration between two classes of people who have
never expressed any desire to couple together in history because they
travel on two different paths in two different directions.; is the
realization of the truth that success in language technology that aims at
improving the present status of the common people demands for
unconditional interdependency between linguists and computer
scientists.
Integration of the knowledge of linguistics and language technology
assists in developing detailed knowledge about the features and
functions of the properties of which can only be availed from a corpora.
It is almost impossible to develop software for language technology
unless without detailed knowledge of
i. Language usage
ii. Language structure
iii. Language properties and how these properties are utilized
iv. How linguistic elements are used when people use language in speech
and writing, etc.
Linguists, although well versed in language and linguistics, are crippled
if they do not have an idea about using computers in their works. The
respective needs have combined these two streams together to give
birth to a new field known as 'computational linguistics'.
 The direct effect of this collaboration is the birth of a new generation of
scientists who are known as 'computational linguists', who know both
linguistics and computer science.
 1970s and 1980s, recorded that linguists had to depend on computer scientists to
write programs for them or to extract necessary information from corpora stored in
computers.
 Linguists relied heavily on computer experts for doing their works making computer
scientists wait for necessary instructions and guidance from linguists for executing
works on corpus databases.
 Such interdependency not only reduced the normal pace of work of both the groups
but also created many unwanted complexities among the interactive people due to
the underlying gulf of mutual communication; creating a real problem for linguists
who had to depend always on programmers for obtaining relevant information from
corpora for doing linguistic works.
 This dependency, in linguistic research analysis, perennial dependency often
becomes futile, abortive and unproductive
 The birth of computational linguists who are linguists by choice (of profession) and
who know how to write computer programmes as well as to use computers for their
research purposes took place to solve the problem.
Linguists
i. realization of possession of computer with high capacity for language data storage and
management
ii. assist in works related to language analysis and use without any external help
iii. installation of some easily usable corpus processing software in a computer, will allow
them not to depend always on computer scientists.
 a special subgroup belonging to a coveted class in which general linguists have little
chance to enter within linguists can design software for linguistic research and
application.
 scientists who belong to computer science but have enlisted their names in the list of
computational linguists due to sheer love for and interest in the subject.
 A large number of old and seasoned linguists have started learning computer
programming with extra enthusiasm and zeal with an aim of using computers in their
own linguistic activities and shed new insights into this area to enrich both linguistics and
computer science
TRADITIONAL LINGUISTS on COMPUTIONAL LINGISTICS
 introduction of computers in linguistics is comparable to forceful trespass
of a wild rogue in a garden of roses.
corpus that has actually paved the way for inviting computers in linguistics
Computer
i. Is a real misfit in the secluded cloister of thoughtful linguistics
ii. destroys the beauty and charm of linguistics with the presentation of dull
statistical data devoid of life and mystery
Computational analysis of language is neither insightful nor trustworthy
Computational linguistics, is neither time-tested nor certified by rational
interpretations.
 admittance of corpora and computers in linguistics may result in
denial of intuitive observations hidden under the surface of language
structures.
 a 'skin-deep' subject, it deals only with surface structures and hardly
succeeds in reflecting on the internal structure of language.
 its judgments are often error prone and conclusions usually skewed
 linguistics will definitely lose its honor, dignity and glamour if it is put
within the mechanical frame of computation
 computational linguistics and find sadistic pleasure in criticizing
people who use computers in the study of linguistics.
The Reign of English
English has been used as the most supportive language for linguistic
research, investigation and application as well as for the formation of
linguistic theories and principles.
traditional, structural and generative linguistics or in language
technology, most of the linguistic investigations and experiments have
been carried out in English
e formulated rules on specific linguistic features just because that has
been observed in English
use of English in almost all fields of knowledge across the world, its
status as the main or second language in many countries
 English is used as the primary language in which works of language technology are
carried out and the results of these activities are published in various journals and
newsletters.
both native and non-native users of English are ardently involved in developing tools
and systems for English. In fact, the number of non-native speakers of English
working for the English language easily exceeds the number of native English
speakers working for it. A large number of Indians, along with the Asian and African
experts, have joined this group to design and develop some outstanding language
processing tools and techniques for English. If these had been developed for their
native languages these would have been some excellent path breaking contributions
to their own country, languages and people.
