Orders, Decorations, And Medals Of The Czech Republic
State decorations of the Czech Republic recognize outstanding acts of service to the Czech Republic. They are awarded by the President of the Czech Republic, usually, but not necessarily, on the recommendation of the Chamber of Deputies, the Senate or the Prime Minister of the Czech Republic. They may also be promulgated solely on the president's authority. They come in two varieties: ''orders'' being the higher honor and ''medals'' the lower. History As originally envisioned by the constitution in 1992, the president had little more than a ceremonial role with respect to state decorations. Article 63 promulgated an order or an award on the recommendation of the government, as expressed by the signature of the Prime Minister. The constitution did not clearly give the president a way to refuse such a referral, unless it came to him by way of a law to be enacted, thus subject to his veto. Nothing in the constitution suggests that a recommendation for decoration be voted on by pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lauri Karttunen
Lauri Juhani Karttunen (September 29, 1941 – March 20, 2022) was an adjunct professor in linguistics at Stanford and an ACL Fellow. Career Karttunen received his Ph.D. in Linguistics in 1969 from Indiana University in Bloomington. At the University of Texas at Austin in the 1970s he worked mostly on semantics. He published a series of seminal papers on discourse referents, presupposition In linguistics and philosophy, a presupposition is an implicit assumption about the world or background belief relating to an utterance whose truth is taken for granted in discourse. Examples of presuppositions include: * ''Jane no longer writes ...s, implicative verbs, conventional implicatures, and questions. In the 1980s Karttunen became, along with Ronald M. Kaplan, Martin Kay, and Kimmo Koskenniemi, one of the pioneers in computational linguistics on the application of finite-state transducers to phonology and morphology. Karttunen and Kenneth R. Beesley published a textbook on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martin Kay
Martin Kay (1935 – 7 August 2021) was a British computer scientist, known especially for his work in computational linguistics. Born and raised in the United Kingdom, he received his M.A. from Trinity College, Cambridge, in 1961. In 1958 he started to work at the Cambridge Language Research Unit, one of the earliest centres for research in what is now known as Computational Linguistics. In 1961, he moved to the Rand Corporation in Santa Monica, California, US, where he eventually became head of research in linguistics and machine translation. He left Rand in 1972 to become Chair of the Department of Computer Science at the University of California, Irvine. In 1974, he moved to the Xerox Palo Alto Research Center as a Research Fellow. In 1985, while retaining his position at Xerox PARC, he joined the faculty of Stanford University half-time. He was most recently Professor of Linguistics at Stanford University and Honorary Professor of Computational Linguistics at Saarland Univ ...

Dependency Grammar
Dependency grammar (DG) is a class of modern Grammar, grammatical theories that are all based on the dependency relation (as opposed to the ''constituency relation'' of Phrase structure grammar, phrase structure) and that can be traced back primarily to the work of Lucien Tesnière. Dependency is the notion that linguistic units, e.g. words, are connected to each other by directed links. The (finite) verb is taken to be the structural center of clause structure. All other syntactic units (words) are either directly or indirectly connected to the verb in terms of the directed links, which are called ''dependencies''. Dependency grammar differs from phrase structure grammar in that while it can identify phrases it tends to overlook phrasal nodes. A dependency structure is determined by the relation between a word (a Head (linguistics), head) and its dependents. Dependency structures are flatter than phrase structures in part because they lack a finite verb, finite verb phrase constit ...

Deep Structure And Surface Structure
Deep structure and surface structure (also D-structure and S-structure although those abbreviated forms are sometimes used with distinct meanings) are concepts used in linguistics, specifically in the study of syntax in the Chomskyan tradition of transformational generative grammar. The deep structure of a linguistic expression is a theoretical construct that seeks to unify several related structures. For example, the sentences "Pat loves Chris" and "Chris is loved by Pat" mean roughly the same thing and use similar words. Some linguists, Chomsky in particular, have tried to account for this similarity by positing that these two sentences are distinct ''surface forms'' that derive from a common (or very similar) deep structure. Origin Chomsky coined and popularized the terms "deep structure" and "surface structure" in the early 1960s. American linguist Sydney Lamb wrote in 1975 that Chomsky "probably orrowedthe term from Hockett". American linguist Charles Hockett first use ...

Morphology (linguistics)
In linguistics, morphology is the study of words, including the principles by which they are formed, and how they relate to one another within a language. Most approaches to morphology investigate the structure of words in terms of morphemes, which are the smallest units in a language with some independent meaning. Morphemes include roots that can exist as words by themselves, but also categories such as affixes that can only appear as part of a larger word. For example, in English the root ''catch'' and the suffix ''-ing'' are both morphemes; ''catch'' may appear as its own word, or it may be combined with ''-ing'' to form the new word ''catching''. Morphology also analyzes how words behave as parts of speech, and how they may be inflected to express grammatical categories including number, tense, and aspect. Concepts such as productivity are concerned with how speakers create words in specific contexts, which evolves over the history of a language. The basic fields of ling ...

Czech Language
Czech ( ; ), historically known as Bohemian ( ; ), is a West Slavic language of the Czech–Slovak group, written in Latin script. Spoken by over 12 million people including second language speakers, it serves as the official language of the Czech Republic. Czech is closely related to Slovak, to the point of high mutual intelligibility, as well as to Polish to a lesser degree. Czech is a fusional language with a rich system of morphology and relatively flexible word order. Its vocabulary has been extensively influenced by Latin and German. The Czech–Slovak group developed within West Slavic in the high medieval period, and the standardization of Czech and Slovak within the Czech–Slovak dialect continuum emerged in the early modern period. In the later 18th to mid-19th century, the modern written standard became codified in the context of the Czech National Revival. The most widely spoken non-standard variety, known as Common Czech, is based on the vernacular of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Treebank
In linguistics, a treebank is a parsed text corpus that annotates syntactic or semantic sentence structure. The construction of parsed corpora in the early 1990s revolutionized computational linguistics, which benefitted from large-scale empirical data. Etymology The term ''treebank'' was coined by linguist Geoffrey Leech in the 1980s, by analogy to other repositories such as a seedbank or bloodbank. This is because both syntactic and semantic structure are commonly represented compositionally as a tree structure. The term ''parsed corpus'' is often used interchangeably with the term treebank, with the emphasis on the primacy of sentences rather than trees. Construction Treebanks are often created on top of a corpus that has already been annotated with part-of-speech tags. In turn, treebanks are sometimes enhanced with semantic or other linguistic information. Treebanks can be created completely manually, where linguists annotate each sentence with syntactic structur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Topic And Comment
In linguistics, the topic, or theme, of a sentence is what is being talked about, and the comment (rheme or focus) is what is being said about the topic. This division into old vs. new content is called information structure. It is generally agreed that clauses are divided into topic vs. comment, but in certain cases the boundary between them depends on which specific grammatical theory is being used to analyze the sentence. The topic of a sentence is distinct from the grammatical subject. The topic is defined by pragmatic considerations, that is, the context that provides meaning. The grammatical subject is defined by syntax. In any given sentence the topic and grammatical subject may be the same, but they need not be. For example, in the sentence "As for the little girl, the dog bit her", the subject is "the dog" but the topic is "the little girl". Topic being what is being talked about and the subject being what is doing the action can, also, be distinct concepts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syntax
In linguistics, syntax ( ) is the study of how words and morphemes combine to form larger units such as phrases and sentences. Central concerns of syntax include word order, grammatical relations, hierarchical sentence structure (constituency), agreement, the nature of crosslinguistic variation, and the relationship between form and meaning (semantics). Diverse approaches, such as generative grammar and functional grammar, offer unique perspectives on syntax, reflecting its complexity and centrality to understanding human language. Etymology The word ''syntax'' comes from the ancient Greek word , meaning an orderly or systematic arrangement, which consists of (''syn-'', "together" or "alike"), and (''táxis'', "arrangement"). In Hellenistic Greek, this also specifically developed a use referring to the grammatical order of words, with a slightly altered spelling: . The English term, which first appeared in 1548, is partly borrowed from Latin () and Greek, though the L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Functional Generative Description
Functional generative description (FGD) is a linguistic framework developed at Charles University in Prague since the 1960s by a team led by Petr Sgall. Based on the dependency grammar formalism, it is a stratificational grammar formalism that treats the sentence as a system of interlinked layers: phonological, Morpheme, morphematical, morphonological, analytical (Deep structure and surface structure, surface syntax) and tectogrammatical (Deep structure and surface structure, deep syntax). Continuing the tradition of Prague School, special attention is paid to the phenomenon of topic–focus articulation. The Prague Dependency Treebank (PDT) is a treebank consisting of a subset of the Czech National Corpus annotated along the lines of FGD.
