CHILDES
The Child Language Data Exchange System (CHILDES) is a corpus established in 1984 by Brian MacWhinney and Catherine Snow to serve as a central repository for data of first language acquisition. Its earliest transcripts date from the 1960s, and it now has contents (transcripts, audio, and video) in 26 languages from 130 different corpora, all of which are publicly available worldwide. Recently, CHILDES has been made into a component of the larger corpus TalkBank, which also includes language data from aphasics, second language acquisition, conversation analysis, and classroom language learning. CHILDES is mainly used for analyzing the language of young children and directed to the child speech of adults. During the early 1990s, as computational resources capable of easily manipulating the data volumes found in CHILDES became commonly available, there was a significant increase in the number of studies of child language acquisition that made use of it. CHILDES is currently direct ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

CLAN Program
The CLAN (Computerized Language ANalysis) program is a cross-platform program designed by Brian MacWhinney and written by Leonid Spektor for the purpose of creating and analyzing transcripts in the Child Language Exchange System (CHILDES) CHILDES, database. CLAN is open source software and can be freely downloaded. History From 1984 until 2000, CLAN was used exclusively for the analysis of child language data. However, beginning with the funding of the TalkBank system by the National Science Foundation (NSF) in 2000, the scope of CLAN has broadened. CLAN is now being used to create and analyze a wide variety of corpora in the context of these databanks: CHILDES for child language, AphasiaBank for aphasia, PhonBank for phonology, FluencyBank for fluency disorders, HomeBank for daylong recordings in the home, and SLABank for second language acquisition. The TalkBank website also provides data for seven other spoken language banks dealing with CA (Conversation Analysis), RHD (right he ...

Conversation Analysis
Conversation analysis (CA) is an approach to the study of social interaction, embracing both verbal and non-verbal conduct, in situations of everyday life. CA originated as a sociological method, but has since spread to other fields. CA began with a focus on casual conversation, but its methods were subsequently adapted to embrace more task- and institution-centered interactions, such as those occurring in doctors' offices, courts, law enforcement, helplines, educational settings, and the mass media, and focus on nonverbal activity in interaction, including gaze, body movement and gesture. As a consequence, the term ''conversation analysis'' has become something of a misnomer, but it has continued as a term for a distinctive and successful approach to the analysis of interactions. CA and ethnomethodology are sometimes considered one field and referred to as ''EMCA''. History Conversation analysis was developed in the late 1960s and early 1970s principally by the sociologist Harv ...

Speech Corpus
A speech corpus (or spoken corpus) is a database of speech audio files and text transcriptions. In speech technology, speech corpora are used, among other things, to create acoustic models (which can then be used with a speech recognition or speaker identification engine). In linguistics, spoken corpora are used to do research into phonetic, conversation analysis, dialectology and other fields. A corpus is one such database. Corpora is the plural of corpus (i.e. it is many such databases). There are two types of Speech Corpora: # Read Speech – which includes: #* Book excerpts #* Broadcast news #* Lists of words #* Sequences of numbers # Spontaneous Speech – which includes: #* Dialogs – between two or more people (includes meetings; one such corpus is the KEC); #* Narratives – a person telling a story (one such corpus is the Buckeye Corpus); #* Map-tasks – one person explains a route on a map to another; #* Appointment-tasks – two people try to find a common meeti ...

Catherine E
Katherine, also spelled Catherine, and Catherina, other variations are feminine Given name, names. They are popular in Christian countries because of their derivation from the name of one of the first Christian saints, Catherine of Alexandria. In the early Christian era it came to be associated with the Greek adjective (), meaning "pure", leading to the alternative spellings ''Katharine'' and ''Katherine''. The former spelling, with a middle ''a'', was more common in the past and is currently more popular in the United States than in United Kingdom, Britain. ''Katherine'', with a middle ''e'', was first recorded in England in 1196 after being brought back from the Crusades. Popularity and variations English In Britain and the U.S., ''Catherine'' and its variants have been among the 100 most popular names since 1880. The most common variants are ''Katherine,'' ''Kathryn,'' and ''Katharine''. The spelling ''Catherine'' is common in both English and French language, French ...

Language Acquisition
Language acquisition is the process by which humans acquire the capacity to perceive and comprehend language (in other words, gain the ability to be aware of language and to understand it), as well as to produce and use words and sentences to communicate. Language acquisition involves structures, rules and representation. The capacity to use language successfully requires one to acquire a range of tools including phonology, morphology, syntax, semantics, and an extensive vocabulary. Language can be vocalized as in speech, or manual as in sign. Human language capacity is represented in the brain. Even though human language capacity is finite, one can say and understand an infinite number of sentences, which is based on a syntactic principle called recursion. Evidence suggests that every individual has three recursive mechanisms that allow sentences to go indeterminately. These three mechanisms are: ''relativization'', ''complementation'' and ''coordination''. There are two ma ...

Aphasia
Aphasia is an inability to comprehend or formulate language because of damage to specific brain regions. The major causes are stroke and head trauma; prevalence is hard to determine but aphasia due to stroke is estimated to be 0.1–0.4% in the Global North. Aphasia can also be the result of brain tumors, brain infections, or neurodegenerative diseases (such as dementias). To be diagnosed with aphasia, a person's speech or language must be significantly impaired in one (or more) of the four aspects of communication following acquired brain injury. Alternatively, in the case of progressive aphasia, it must have significantly declined over a short period of time. The four aspects of communication are auditory comprehension, verbal expression, reading and writing, and functional communication. The difficulties of people with aphasia can range from occasional trouble finding words, to losing the ability to speak, read, or write; intelligence, however, is unaffected. Expressive lan ...

Second Language Acquisition
Second-language acquisition (SLA), sometimes called second-language learning — otherwise referred to as L2 (language 2) acquisition, is the process by which people learn a second language. Second-language acquisition is also the scientific discipline devoted to studying that process. The field of second-language acquisition is regarded by some but not everybody as a sub-discipline of applied linguistics but also receives research attention from a variety of other disciplines, such as psychology and education. A central theme in SLA research is that of ''interlanguage:'' the idea that the language that learners use is not simply the result of differences between the languages that they already know and the language that they are learning, but a complete language system in its own right, with its own systematic rules. This interlanguage gradually develops as learners are exposed to the targeted language. The order in which learners acquire features of their new language stays rem ...

Carnegie Mellon University
Carnegie Mellon University (CMU) is a private research university in Pittsburgh, Pennsylvania. One of its predecessors was established in 1900 by Andrew Carnegie as the Carnegie Technical Schools; it became the Carnegie Institute of Technology in 1912 and began granting four-year degrees in the same year. In 1967, the Carnegie Institute of Technology merged with the Mellon Institute of Industrial Research, founded in 1913 by Andrew Mellon and Richard B. Mellon and formerly a part of the University of Pittsburgh. Carnegie Mellon University has operated as a single institution since the merger. The university consists of seven colleges and independent schools: The College of Engineering, College of Fine Arts, Dietrich College of Humanities and Social Sciences, Mellon College of Science, Tepper School of Business, Heinz College of Information Systems and Public Policy, and the School of Computer Science. The university has its main campus located 5 miles (8 km) from Downto ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Phonological
Phonology is the branch of linguistics that studies how languages or dialects systematically organize their sounds or, for sign languages, their constituent parts of signs. The term can also refer specifically to the sound or sign system of a particular language variety. At one time, the study of phonology related only to the study of the systems of phonemes in spoken languages, but may now relate to any linguistic analysis either: Sign languages have a phonological system equivalent to the system of sounds in spoken languages. The building blocks of signs are specifications for movement, location, and handshape. At first, a separate terminology was used for the study of sign phonology ('chereme' instead of 'phoneme', etc.), but the concepts are now considered to apply universally to all human languages. Terminology The word 'phonology' (as in 'phonology of English') can refer either to the field of study or to the phonological system of a given language. This is one of th ...

Morphology (linguistics)
In linguistics, morphology () is the study of words, how they are formed, and their relationship to other words in the same language. It analyzes the structure of words and parts of words such as stems, root words, prefixes, and suffixes. Morphology also looks at parts of speech, intonation and stress, and the ways context can change a word's pronunciation and meaning. Morphology differs from morphological typology, which is the classification of languages based on their use of words, and lexicology, which is the study of words and how they make up a language's vocabulary. While words, along with clitics, are generally accepted as being the smallest units of syntax, in most languages, if not all, many words can be related to other words by rules that collectively describe the grammar for that language. For example, English speakers recognize that the words ''dog'' and ''dogs'' are closely related, differentiated only by the plurality morpheme "-s", only found bound to noun ...
