Case Grammar
Case grammar is a system of linguistic analysis, focusing on the link between the valence, or number of subjects, objects, etc., of a verb and the grammatical context it requires. The system was created by the American linguist Charles J. Fillmore in the context of Transformational Grammar (1968). This theory analyzes the surface syntactic structure of sentences by studying the combination of deep cases (i.e. semantic roles, such as Agent, Object, Benefactor, Location or Instrument etc.) which are required by a specific verb. For instance, the verb "give" in English requires an Agent (A) and Object (O), and a Beneficiary (B); e.g. "Jones (A) gave money (O) to the school (B). According to Fillmore, each verb selects a certain number of deep cases which form its case frame. Thus, a case frame describes important aspects of semantic valency of verbs, adjectives and nouns. Case frames are subject to certain constraints, such as that a deep case can occur only once per sentenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linguistic Analysis
In the study of language, description or descriptive linguistics is the work of objectively analyzing and describing how language is actually used (or how it was used in the past) by a speech community. François & Ponsonnet (2013). All academic research in linguistics is descriptive; like all other scientific disciplines, it aims to describe reality, without the bias of preconceived ideas about how it ought to be. Modern descriptive linguistics is based on a structural approach to language, as exemplified in the work of Leonard Bloomfield and others. This type of linguistics utilizes different methods in order to describe a language such as basic data collection, and different types of elicitation methods. Descriptive versus prescriptive linguistics Linguistic description, as used in academic and professional linguistics, is often contrasted with linguistic prescription, — entry for "Descriptivism and prescriptivism" quotation: "Contrasting terms in linguistics."

Thematic Structure
Thematic structure is a concept in linguistics. When people talk, there are purposes in three separable parts of utterances, the act of speech, the propositional content and the thematic structure. Because speaking is cooperative, in order that the speaking can be effective in the conversation, speakers have to pay attention to their listeners’ knowledge, state of mind and level of understanding. Speakers can assume that listeners know or do not know what speakers are talking about. According to Michael Halliday Michael Alexander Kirkwood Halliday (often M. A. K. Halliday; 13 April 1925 – 15 April 2018) was a British linguist who developed the internationally influential systemic functional linguistics (SFL) model of language. His grammatical descri ..., the speakers’ judgements about the listeners’ current mental states are reflected in what is called the thematic structure used. The thematic structure has three main functions: *To convey given information and ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theta Role
Theta roles are the names of the participant roles associated with a predicate: the predicate may be a verb, an adjective, a preposition, or a noun. If an object is in motion or in a steady state as the speakers perceives the state, or it is the topic of discussion, it is called a theme. The participant is usually said to be an argument of the predicate. 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 k ...

Thematic Relation
In certain theories of linguistics, thematic relations, also known as semantic roles or thematic roles, are the various roles that a noun phrase may play with respect to the action or state described by a governing verb, commonly the sentence's main verb. For example, in the sentence "Susan ate an apple", ''Susan'' is the doer of the eating, so she is an Agent (grammar), agent; ''an apple'' is the item that is eaten, so it is a Patient (grammar), patient. Since their introduction in the mid-1960s by Jeffrey Gruber and Charles J. Fillmore, Charles Fillmore, semantic roles have been a core linguistic concept and ground of debate between linguist approaches, because of their potential in explaining the relationship between syntax and semantics (also known as the syntax-semantics interface), that is how meaning affects the surface syntactic codification of language. The notion of semantic roles play a central role especially in functionalist linguistics, functionalist and language-com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Frame Semantics (linguistics)
Frame semantics is a theory of linguistic meaning developed by Charles J. Fillmore that extends his earlier case grammar. It relates linguistic semantics to encyclopedic knowledge. The basic idea is that one cannot understand the meaning of a single word without access to all the essential knowledge that relates to that word. For example, one would not be able to understand the word "sell" without knowing anything about the situation of commercial transfer, which also involves, among other things, a seller, a buyer, goods, money, the relation between the money and the goods, the relations between the seller and the goods and the money, the relation between the buyer and the goods and the money and so on. Thus, a word activates, or evokes, a frame of semantic knowledge relating to the specific concept to which it refers (or highlights, in frame semantic terminology). The idea of the encyclopedic organisation of knowledge itself is old and was discussed by Age of Enlightenment ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artificial Intelligence
Artificial intelligence (AI) is the capability of computer, computational systems to perform tasks typically associated with human intelligence, such as learning, reasoning, problem-solving, perception, and decision-making. It is a field of research in computer science that develops and studies methods and software that enable machines to machine perception, perceive their environment and use machine learning, learning and intelligence to take actions that maximize their chances of achieving defined goals. High-profile applications of AI include advanced web search engines (e.g., Google Search); recommendation systems (used by YouTube, Amazon (company), Amazon, and Netflix); virtual assistants (e.g., Google Assistant, Siri, and Amazon Alexa, Alexa); autonomous vehicles (e.g., Waymo); Generative artificial intelligence, generative and Computational creativity, creative tools (e.g., ChatGPT and AI art); and Superintelligence, superhuman play and analysis in strategy games (e.g., ...

Knowledge Representation
Knowledge representation (KR) aims to model information in a structured manner to formally represent it as knowledge in knowledge-based systems whereas knowledge representation and reasoning (KRR, KR&R, or KR²) also aims to understand, reason, and interpret knowledge. KRR is widely used in the field of artificial intelligence (AI) with the goal to represent information about the world in a form that a computer system can use to solve complex tasks, such as diagnosing a medical condition or having a natural-language dialog. KR incorporates findings from psychology about how humans solve problems and represent knowledge, in order to design formalisms that make complex systems easier to design and build. KRR also incorporates findings from logic to automate various kinds of ''reasoning''. Traditional KRR focuses more on the declarative representation of knowledge. Related knowledge representation formalisms mainly include vocabularies, thesaurus, semantic networks, axiom system ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frame (artificial Intelligence)
Frames are an artificial intelligence data structure used to divide knowledge into substructures by representing "stereotyped situations". They were proposed by Marvin Minsky in his 1974 article "A Framework for Representing Knowledge". Frames are the primary data structure used in artificial intelligence frame languages; they are stored as Ontology (information science), ontologies of Set theory, sets. Frames are also an extensive part of knowledge representation and reasoning schemes. They were originally derived from semantic networks and are therefore part of structure-based Knowledge representation and reasoning, knowledge representations. According to Stuart J. Russell, Russell and Peter Norvig, Norvig's ''Artificial Intelligence: A Modern Approach'', structural representations assemble "[...]facts about particular objects and event types and arrange the types into a large taxonomy, taxonomic hierarchy analogous to a biological taxonomy".

Government And Binding
Government and binding (GB, GBT) is a theory of syntax and a phrase structure grammar in the tradition of transformational grammar developed principally by Noam Chomsky in the 1980s. This theory is a radical revision of his earlier theories and was later revised in '' The Minimalist Program'' (1995) and several subsequent papers, the latest being ''Three Factors in Language Design'' (2005). Although there is a large literature on government and binding theory which is not written by Chomsky, Chomsky's papers have been foundational in setting the research agenda. The name refers to two central subtheories of the theory: ''government'', which is an abstract syntactic relation applicable, among other things, to the assignment of case; and '' binding'', which deals chiefly with the relationships between pronouns and the expressions with which they are co-referential. GB was the first theory to be based on the principles and parameters model of language, which also underlies the later ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Object (grammar)
In linguistics, an object is any of several types of arguments. In subject-prominent, nominative-accusative languages such as English, a transitive verb typically distinguishes between its subject and any of its objects, which can include but are not limited to direct objects, indirect objects, and arguments of adpositions ( prepositions or postpositions); the latter are more accurately termed ''oblique arguments'', thus including other arguments not covered by core grammatical roles, such as those governed by case morphology (as in languages such as Latin) or relational nouns (as is typical for members of the Mesoamerican Linguistic Area). In ergative-absolutive languages, for example most Australian Aboriginal languages, the term "subject" is ambiguous, and thus the term " agent" is often used instead to contrast with "object", such that basic word order is often spoken of in terms such as Agent-Object-Verb (AOV) instead of Subject-Object-Verb (SOV). Topic-prominent la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valency (linguistics)
In linguistics, valency or valence is the number and type of arguments and complements controlled by a predicate, content verbs being typical predicates. Valency is related, though not identical, to subcategorization and transitivity, which count only object arguments – valency counts all arguments, including the subject. The linguistic meaning of valency derives from the definition of valency in chemistry. Like valency found in chemistry, there is the binding of specific elements. In the grammatical theory of valency, the verbs organize sentences by binding the specific elements. Examples of elements that would be bound would be the complement and the actant. Although the term originates from valence in chemistry, linguistic valency has a close analogy in mathematics under the term arity. The valency metaphor appeared first in linguistics in Charles Sanders Peirce's essay "The Logic of Relatives" in 1897, and it then surfaced in the works of a number of linguists decade ...
