Role And Reference Grammar
Role and reference grammar (RRG) is a model of grammar developed by William A. Foley and Robert Van Valin, Jr. in the 1980s, which incorporates many of the points of view of current functional grammar theories. In RRG, the description of a sentence in a particular language is formulated in terms of (a) its logical (semantic) structure and communicative functions, and (b) the grammatical procedures that are available in the language for the expression of these meanings. Among the main features of RRG are the use of lexical decomposition, based upon the predicate semantics of David Dowty (1979), an analysis of clause structure, and the use of a set of thematic roles organized into a hierarchy in which the highest-ranking roles are 'Actor' (for the most active participant) and 'Undergoer'. RRG's practical approach to language is demonstrated in the multilingual Natural Language Understanding (NLU) system of cognitive scientist John Ball. In 2012, Ball integrated hiPatom Theoryw ...

Grammar
In linguistics, the grammar of a natural language is its set of structure, structural constraints on speakers' or writers' composition of clause (linguistics), clauses, phrases, and words. The term can also refer to the study of such constraints, a field that includes domains such as phonology, morphology (linguistics), morphology, and syntax, often complemented by phonetics, semantics, and pragmatics. There are currently two different approaches to the study of grammar: traditional grammar and Grammar#Theoretical frameworks, theoretical grammar. Fluency, Fluent speakers of a variety (linguistics), language variety or ''lect'' have effectively internalized these constraints, the vast majority of which – at least in the case of one's First language, native language(s) – are language acquisition, acquired not by conscious study or language teaching, instruction but by hearing other speakers. Much of this internalization occurs during early childhood; learning a language later ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William A
William is a male given name of Germanic origin.Hanks, Hardcastle and Hodges, ''Oxford Dictionary of First Names'', Oxford University Press, 2nd edition, , p. 276. It became very popular in the English language after the Norman conquest of England in 1066,All Things William"Meaning & Origin of the Name"/ref> and remained so throughout the Middle Ages and into the modern era. It is sometimes abbreviated "Wm." Shortened familiar versions in English include Will, Wills, Willy, Willie, Bill, and Billy. A common Irish form is Liam. Scottish diminutives include Wull, Willie or Wullie (as in Oor Wullie or the play ''Douglas''). Female forms are Willa, Willemina, Wilma and Wilhelmina. Etymology William is related to the given name ''Wilhelm'' (cf. Proto-Germanic ᚹᛁᛚᛃᚨᚺᛖᛚᛗᚨᛉ, ''*Wiljahelmaz'' > German ''Wilhelm'' and Old Norse ᚢᛁᛚᛋᛅᚼᛅᛚᛘᛅᛋ, ''Vilhjálmr'').

Robert Van Valin, Jr
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It can be use ...

Functional Theories Of Grammar
Functional linguistics is an approach to the study of language characterized by taking systematically into account the speaker's and the hearer's side, and the communicative needs of the speaker and of the given language community. Linguistic functionalism spawned in the 1920s to 1930s from Ferdinand de Saussure's systematic structuralist approach to language (1916). Functionalism sees functionality of language and its elements to be the key to understanding linguistic processes and structures. Functional theories of language propose that since language is fundamentally a tool, it is reasonable to assume that its structures are best analyzed and understood with reference to the functions they carry out. These include the tasks of conveying meaning and contextual information. Functional theories of grammar belong to structural and humanistic linguistics, considering language as a rational human construction. They take into account the context where linguistic elements are used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lexical Decomposition
Lexical may refer to: Linguistics * Lexical corpus or lexis, a complete set of all words in a language * Lexical item, a basic unit of lexicographical classification * Lexicon, the vocabulary of a person, language, or branch of knowledge * Lexical (semiotics) or content word, words referring to ''things'', as opposed to having only grammatical meaning ** Lexical verb, a member of an open class of verbs that includes all verbs except auxiliary verbs * Lexical aspect, a characteristic of the meaning of verbs * Lexical form, the canonical form of a word, under which it appears in dictionaries * Lexical definition or dictionary definition, the meaning of a term in common usage * Lexical semantics, a subfield of linguistic semantics that studies how and what the words of a language denote Computing * Lexical analysis, the process of converting a sequence of characters into a sequence of tokens * Lexical Markup Framework, the ISO standard for natural language processing and machine-reada ...

David Dowty
David Roach Dowty (born 1945) is a linguist known primarily for his work in semantic and syntactic theory, and especially in Montague grammar and Categorial grammar. Dowty is a professor emeritus of linguistics at the Ohio State University, and his research interests mainly lie in Semantic and Syntactic Theory, Lexical semantics and Thematic roles, Categorial grammar, and Semantics of Tense and Aspect. Life David Dowty received his PhD from the University of Texas at Austin, with a thesis supervised by Robert Wall and Emmon Bach on the temporal semantics of verbs. Dowty was editor-in-chief of the journal ''Linguistics and Philosophy'' from 1988 to 1992, and associate editor of ''Language''. For several years he was chairman of the Department of Linguistics at the Ohio State University. A one-day symposium was held at the University of Groningen in honour of his sixtieth birthday, subsequently published as ''Theory and Evidence in Semantics''. Major Publications * ''Word Mean ...

Clause
In language, a clause is a constituent that comprises a semantic predicand (expressed or not) and a semantic predicate. A typical clause consists of a subject and a syntactic predicate, the latter typically a verb phrase composed of a verb with any objects and other modifiers. However, the subject is sometimes unvoiced if it is retrievable from context, especially in null-subject language but also in other languages, including English instances of the imperative mood. A complete simple sentence includes a single clause with a finite verb. Complex sentences contain multiple clauses including at least one ''independent clause'' (meaning, a clause that can stand alone as a simple sentence) coordinated either with at least one dependent clause (also called an embedded clause) or with one or more independent clauses. Two major distinctions A primary division for the discussion of clauses is the distinction between independent clauses and dependent clauses. An independent clause can s ...

Theta Role
In generative grammar, a theta role or θ-role is the formal device for representing syntactic argument structure—the number and type of noun phrases—required syntactically by a particular verb. For example, the verb ''put'' requires three arguments (i.e., it is trivalent). The formal mechanism for implementing a verb's argument structure is codified as theta roles. The verb ''put'' is said to "assign" three theta roles. This is coded in a theta grid associated with the lexical entry for the verb. The correspondence between the theta grid and the actual sentence is accomplished by means of a bijective filter on the grammar known as the theta criterion. Early conceptions of theta roles include (Fillmore called theta roles "cases") and . Theta roles are prominent in government and binding theory and the standard theory of transformational grammar. Thematic relations The term "theta role" is often used interchangeably with the term thematic relations (particularly in mai ...

Natural Language Understanding
Natural-language understanding (NLU) or natural-language interpretation (NLI) is a subtopic of natural-language processing in artificial intelligence that deals with machine reading comprehension. Natural-language understanding is 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 natural-language understanding 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, J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Ball (cognitive Scientist)
John Samuel Ball (born 1963) is an American cognitive scientist, an expert in machine intelligence, computer architecture and the inventor of Patom Theory. Biography Born in Iowa USA whilst his Australian father Samuel Ball was working on his PhD in Educational Psychology, Ball returned with the family to Australia in 1978 to finish his secondary schooling on the north shore of Sydney. Ball received a Bachelor of Science in 1984 from thUniversity of Sydney a Masters of Cognitive Science froUniversity of NSWin 1989 and a Master of Business Administration from MGSMMacquarie Graduate School of Management in 1997. From a young age, Ball was fascinated by computers having been exposed to early mainframes at Educational Testing Service (ETS) in Princeton in the 1970s. He was challenged by a lecturer as an undergraduate to pursue machine intelligence when she announced that computers would never be able to perform human like functions such as language or visual recognition.

Relational Grammar
In linguistics, relational grammar (RG) is a syntactic theory which argues that primitive grammatical relations provide the ideal means to state syntactic rules in universal terms. Relational grammar began as an alternative to transformational grammar. Grammatical relations hierarchy In relational grammar, constituents that serve as the arguments to predicates are numbered in what is called the grammatical relations (GR) hierarchy. This numbering system corresponds loosely to the notions of subject, direct object and indirect object. The numbering scheme is subject → (1), direct object → (2) and indirect object → (3). Other constituents (such as oblique, genitive, and object of comparative) are called ''nonterms'' (N). The predicate is marked (P). According to Geoffrey K. Pullum (1977), the GR hierarchy directly corresponds to the accessibility hierarchy: A schematic representation of a clause in this formalism might look like: Other features * Strata * Chomage (s ...
