The semantic gap characterizes the difference between two descriptions of an object by different linguistic representations, for instance languages or symbols. According to Andreas M. Hein, the semantic gap can be defined as "the difference in meaning between constructs formed within different representation systems". [ 1 ]
The semantic approach of philosophers like Stephen Neale [3] suggests that the sentence does in fact have the appropriate meaning as to make it true. Such meaning is added to the sentence by the particular context of the speaker—that, say, the context of standing next to a table "completes" the sentence.
[3] [1] Many words, often self-consciously borrowed from classical literature, were deemed useless by critics who argued that the understanding of these redundant borrowings depends on knowledge of classical languages. Some borrowings filled a technical or scientific semantic gap, but others coexisted with Germanic words, often overtaking them.
If a single word undergoes a semantic change, then the whole structure of the lexical field changes. The lexical field is often used in English to describe terms further with use of different words. Trier's theory assumes that lexical fields are easily definable closed sets, [1] with no overlapping meanings or gaps. These assumptions have been ...
The semantic gap is often mentioned in regard to CBIR. The semantic gap refers to the gap between the information that can be extracted from visual data and the interpretation that the same data have for a user in a given situation. [17] The ACM SIGMM Workshop on Multimedia Information Retrieval [18] is dedicated to studies of CBIR.
Coherence in linguistics is what makes a text semantically meaningful. It is especially dealt with in text linguistics.Coherence is achieved through syntactic features such as the use of deictic, anaphoric and cataphoric elements or a logical tense structure, and semantic features such as presuppositions and implications connected to general world knowledge.
In linguistics, semantic analysis is the process of relating syntactic structures, from the levels of words, phrases, clauses, sentences and paragraphs to the level of the writing as a whole, to their language-independent meanings. It also involves removing features specific to particular linguistic and cultural contexts, to the extent that ...
Untranslatability is the property of text or speech for which no equivalent can be found when translated into another (given) language. A text that is considered to be untranslatable is considered a lacuna, or lexical gap.
