Parsed
Parsing, syntax analysis, or syntactic analysis is a process of analyzing a string of symbols, either in natural language, computer languages or data structures, conforming to the rules of a formal grammar by breaking it into parts. The term ''parsing'' comes from Latin ''pars'' (''orationis''), meaning part (of speech). The term has slightly different meanings in different branches of linguistics and computer science. Traditional sentence parsing is often performed as a method of understanding the exact meaning of a sentence or word, sometimes with the aid of devices such as sentence diagrams. It usually emphasizes the importance of grammatical divisions such as subject and predicate. Within computational linguistics the term is used to refer to the formal analysis by a computer of a sentence or other string of words into its constituents, resulting in a parse tree showing their syntactic relation to each other, which may also contain semantic information. Some parsing algor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syntactic Ambiguity
Syntactic ambiguity, also known as structural ambiguity, amphiboly, or amphibology, is characterized by the potential for a sentence to yield multiple interpretations due to its ambiguous syntax. This form of ambiguity is not derived from the varied meanings of individual words but rather from the relationships among words and clauses within a sentence, concealing interpretations beneath the word order. Consequently, a sentence presents as syntactically ambiguous when it permits reasonable derivation of several possible grammatical structures by an observer. In jurisprudence, the interpretation of syntactically ambiguous phrases in statutory texts or contracts may be done by courts. Occasionally, claims based on highly improbable interpretations of such ambiguities are dismissed as being frivolous litigation and without merit. The term ''parse forest'' refers to the collection of all possible syntactic structures, known as '' parse trees'', that can represent the ambiguous sente ...

Formal Grammar
A formal grammar is a set of Terminal and nonterminal symbols, symbols and the Production (computer science), production rules for rewriting some of them into every possible string of a formal language over an Alphabet (formal languages), alphabet. A grammar does not describe the semantics, meaning of the strings — only their form. In applied mathematics, formal language theory is the discipline that studies formal grammars and languages. Its applications are found in theoretical computer science, theoretical linguistics, Formal semantics (logic), formal semantics, mathematical logic, and other areas. A formal grammar is a Set_(mathematics), set of rules for rewriting strings, along with a "start symbol" from which rewriting starts. Therefore, a grammar is usually thought of as a language generator. However, it can also sometimes be used as the basis for a "recognizer"—a function in computing that determines whether a given string belongs to the language or is grammatical ...

Interpreter (computing)
In computer science, an interpreter is a computer program that directly executes instructions written in a programming or scripting language, without requiring them previously to have been compiled into a machine language program. An interpreter generally uses one of the following strategies for program execution: # Parse the source code and perform its behavior directly; # Translate source code into some efficient intermediate representation or object code and immediately execute that; # Explicitly execute stored precompiled bytecode made by a compiler and matched with the interpreter's virtual machine. Early versions of Lisp programming language and minicomputer and microcomputer BASIC dialects would be examples of the first type. Perl, Raku, Python, MATLAB, and Ruby are examples of the second, while UCSD Pascal is an example of the third type. Source programs are compiled ahead of time and stored as machine independent code, which is then linked at run-ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garden Path Sentence
A garden-path sentence is a grammatically correct sentence that starts in such a way that a reader's most likely interpretation will be incorrect; the reader is lured into a parse that turns out to be a dead end or yields a clearly unintended meaning. ''Garden path'' refers to the saying " to be led down r upthe garden path", meaning to be deceived, tricked, or seduced. In ''A Dictionary of Modern English Usage'' (1926), Fowler describes such sentences as unwittingly laying a " false scent". Such a sentence leads the reader toward a seemingly familiar meaning that is actually not the one intended. It is a special type of sentence that creates a momentarily ambiguous interpretation because it contains a word or phrase that can be interpreted in multiple ways, causing the reader to begin to believe that a phrase will mean one thing when in reality it means something else. When read, the sentence seems ungrammatical, makes almost no sense, and often requires rereading so that its m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psycholinguistics
Psycholinguistics or psychology of language is the study of the interrelation between linguistic factors and psychological aspects. The discipline is mainly concerned with the mechanisms by which language is processed and represented in the mind and brain; that is, the psychology, psychological and neurobiology, neurobiological factors that enable humans to acquire, use, comprehend, and produce language. Psycholinguistics is concerned with the cognitive faculties and processes that are necessary to produce the grammatical constructions of language. It is also concerned with the perception of these constructions by a listener. Initial forays into psycholinguistics were in the philosophical and educational fields, mainly due to their location in departments other than applied sciences (e.g., cohesive data on how the human brain functioned). Modern research makes use of biology, neuroscience, cognitive science, linguistics, and information science to study how the mind-brain process ...

Machine Translation
Machine translation is use of computational techniques to translate text or speech from one language to another, including the contextual, idiomatic and pragmatic nuances of both languages. Early approaches were mostly rule-based or statistical. These methods have since been superseded by neural machine translation and large language models. History Origins The origins of machine translation can be traced back to the work of Al-Kindi, a ninth-century Arabic cryptographer who developed techniques for systemic language translation, including cryptanalysis, frequency analysis, and probability and statistics, which are used in modern machine translation. The idea of machine translation later appeared in the 17th century. In 1629, René Descartes proposed a universal language, with equivalent ideas in different tongues sharing one symbol. The idea of using digital computers for translation of natural languages was proposed as early as 1947 by England's A. D. Booth and Warr ...

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).

Grammatical Person
In linguistics, grammatical person is the grammatical distinction between deictic references to participant(s) in an event; typically, the distinction is between the speaker ( first person), the addressee ( second person), and others ( third person). A language's set of pronouns is typically defined by grammatical person. ''First person'' includes the speaker (English: ''I'', ''we''), ''second person'' is the person or people spoken to (English: ''your'' or ''you''), and ''third person'' includes all that are not listed above (English: ''he'', ''she'', ''it'', ''they''). It also frequently affects verbs, and sometimes nouns or possessive relationships. Related classifications Number In Indo-European languages, first-, second-, and third-person pronouns are typically also marked for singular and plural forms, and sometimes dual form as well (grammatical number). Inclusive/exclusive distinction Some other languages use different classifying systems, especially in the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subject (grammar)
A subject is one of the two main parts of a Sentence (linguistics), sentence (the other being the Predicate (grammar), predicate, which modifies the subject). For the simple Sentence (linguistics), sentence ''John runs'', ''John'' is the subject, a person or thing about whom the statement is made. Traditionally the subject is the word or phrase which controls the verb in the clause, that is to say with which the verb Agreement (linguistics), agrees (''John is'' but ''John and Mary are''). If there is no verb, as in ''Nicola what an idiot!'', or if the verb has a different subject, as in ''John I can't stand him!'', then 'John' is not considered to be the grammatical subject, but can be described as the ''Topic and comment, topic'' of the sentence. While these definitions apply to simple English sentences, defining the subject is more difficult in more complex sentences and languages. For example, in the sentence ''It is difficult to learn French'', the subject seems to be the wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grammatical Number
In linguistics, grammatical number is a Feature (linguistics), feature of nouns, pronouns, adjectives and verb agreement (linguistics), agreement that expresses count distinctions (such as "one", "two" or "three or more"). English and many other languages present number categories of singular or plural. Some languages also have a Dual (grammatical number), dual, #Trial, trial and #Paucal, paucal number or other arrangements. The word "number" is also used in linguistics to describe the distinction between certain grammatical aspects that indicate the number of times an event occurs, such as the semelfactive aspect, the iterative aspect, etc. For that use of the term, see "Grammatical aspect". Overview Most languages of the world have formal means to express differences of number. One widespread distinction, found in English and many other languages, involves a simple two-way contrast between singular and plural number (''car''/''cars'', ''child''/''children'', etc.).

Inflection
In linguistic Morphology (linguistics), morphology, inflection (less commonly, inflexion) is a process of word formation in which a word is modified to express different grammatical category, grammatical categories such as grammatical tense, tense, grammatical case, case, grammatical voice, voice, grammatical aspect, aspect, grammatical person, person, grammatical number, number, grammatical gender, gender, grammatical mood, mood, animacy, and definiteness. The inflection of verbs is called ''grammatical conjugation, conjugation'', while the inflection of nouns, adjectives, adverbs, etc. can be called ''declension''. An inflection expresses grammatical categories with affixation (such as prefix, suffix, infix, circumfix, and transfix), apophony (as Indo-European ablaut), or other modifications. For example, the Latin verb ', meaning "I will lead", includes the suffix ', expressing person (first), number (singular), and tense-mood (future indicative or present subjunctive). Th ...
