dassociations

Dassociations is a term used in some scholarly writings to describe a class of constrained associations among entities. In this usage, a dassociation is a relation or grouping that only includes pairs or tuples that satisfy a designated predicate D. The idea is to encode which relationships are permitted by the constraint, yielding a context-aware network of links.

There is no single standardized definition, and the term often varies by field. In information science and knowledge representation, D can express co-occurrence within a time window, a thresholded similarity, mutual exclusivity, or other domain-specific conditions.

From a formal standpoint, a dassociation can be modeled as a subset A of a product space (such as E × E or E × E × ...), with the property that every tuple in A satisfies D. Some authors further require A to be maximal under D or to satisfy additional optimization criteria.

Applications include data mining, graph construction, and semantic networks, where dassociations provide multi-criteria links rather than simple unweighted edges. In linguistics they can formalize significant collocations under conditioning factors; in sociology they can represent links within a community constrained by shared attributes.
