Lexical cohesion refers to the way related words are chosen to link elements of a text. There are two forms: repetition and collocation. Repetition uses the same word, or synonyms, antonyms, etc. For example, "Which dress are you going to wear?" – "I will wear my green frock," uses the synonyms "dress" and "frock" for lexical cohesion.
Rather than select a single definition, Gledhill [3] proposes that collocation involves at least three different perspectives: co-occurrence, a statistical view, which sees collocation as the recurrent appearance in a text of a node and its collocates; [4] [5] [6] construction, which sees collocation either as a correlation between a lexeme and ...
In linguistics, co-occurrence or cooccurrence is an above-chance frequency of ordered occurrence of two adjacent terms in a text corpus.Co-occurrence in this linguistic sense can be interpreted as an indicator of semantic proximity or an idiomatic expression.
Collostructional analysis differs from most collocation statistics such that (i) it measures not the association of words to words, but of words to syntactic patterns or constructions; thus, it takes syntactic structure more seriously than most collocation-based analyses;
Proposed formulas are mutual information, t-test, z test, chi-squared test and likelihood ratio. [1] Within the area of corpus linguistics, collocation is defined as a sequence of words or terms which co-occur more often than would be expected by chance. 'Crystal clear', 'middle management', 'nuclear family', and 'cosmetic surgery' are examples ...
A word sketch triple is a triple consisting of headword, grammatical relation, collocation (e.g. man, modifier, young).Considering an underlying text corpus, a word sketch quintuple is a quintuple consisting of headword, grammatical relation, collocation, position of headword in the corpus, position of collocation in the corpus (e.g. man, modifier, young, 104, 103).
Skilled users of the language can produce effects such as humor by varying the normal patterns of collocation. This approach is popular with poets , journalists and advertisers . Collocations may seem natural to native writers and speakers, but are not obvious to non-native speakers.
Syntactic n-grams are n-grams defined by paths in syntactic dependency or constituent trees rather than the linear structure of the text. [9] [10] [11] For example, the sentence "economic news has little effect on financial markets" can be transformed to syntactic n-grams following the tree structure of its dependency relations: news-economic ...
