Co-occurrence
Encyclopedia
Co-occurrence or cooccurrence can either mean concurrence
/ coincidence
or, in a more specific sense, the above-chance frequent occurrence of two term
s from a text corpus
alongside each other in a certain order. Co-occurrence in this linguistic
sense can be interpreted as an indicator of semantic proximity or an idiom
atic expression. In contrast to collocation
, co-occurrence assumes interdependency of the two terms. A co-occurrence restriction is identified when linguistic elements never occur together. Analysis of these restrictions can lead to discoveries about the structure and development of a language.
Concurrence

Coincidence
A coincidence is an event notable for its occurring in conjunction with other conditions, e.g. another event. As such, a coincidence occurs when something uncanny, accidental and unexpected happens under conditions named, but not under a defined relationship...

Collocation
In corpus linguistics, collocation defines a sequence of words or terms that co-occur more often than would be expected by chance. In phraseology, collocation is a sub-type of phraseme. An example of a phraseological collocation is the expression strong tea...
