In syntactic ambiguity, the same sequence of words is interpreted as having different syntactic structures. In contrast, in semantic ambiguity the structure remains the same, but the individual words are interpreted differently. [15] [16] Controlled natural languages are often designed to be unambiguous so that they can be parsed into a logical ...
This ambiguity is an example of scope ambiguity, a phenomenon widely studied in formal semantics. De re/de dicto ambiguity is another notable example of sentence-level ambiguity which has received much attention in linguistics and philosophy. In some analyses, such ambiguities are the semantic reflexes of syntactic ambiguities, though in other ...
A famous example for lexical ambiguity is the following sentence: "Wenn hinter Fliegen Fliegen fliegen, fliegen Fliegen Fliegen hinterher.", meaning "When flies fly behind flies, then flies fly in pursuit of flies." [40] [circular reference] It takes advantage of some German nouns and corresponding verbs being homonymous. While not noticeable ...
Contextual and semantic factors influence processing at a later stage and can induce re-analysis of the syntactic parse. Re-analysis is costly and leads to an observable slowdown in reading. When the parser encounters an ambiguity, it is guided by two principles: late closure and minimal attachment.
Only rewriting the sentence, or placing appropriate punctuation can resolve a syntactic ambiguity. [5] For the notion of, and theoretic results about, syntactic ambiguity in artificial, formal languages (such as computer programming languages), see Ambiguous grammar. Usually, semantic and syntactic ambiguity go hand in hand.
In generative grammar and related approaches, the logical form (LF) of a linguistic expression is the variant of its syntactic structure which undergoes semantic interpretation. It is distinguished from phonetic form , the structure which corresponds to a sentence's pronunciation.
Colorless green ideas sleep furiously was composed by Noam Chomsky in his 1957 book Syntactic Structures as an example of a sentence that is grammatically well-formed, but semantically nonsensical. The sentence was originally used in his 1955 thesis The Logical Structure of Linguistic Theory and in his 1956 paper "Three Models for the ...
Theta roles are syntactic relations that refers to the semantic thematic relations. For example, take the sentence "Reggie gave the kibble to Fergus on Friday." Thematic relations: Reggie is doing the action so is the agent, but he is also the source of the kibble (note Reggie bears two thematic relations); the kibble is the entity acted upon ...
