The term collective entity linking picks up entity linking techniques that take advantage of the interdependency between entities in a body of text to assign simultaneously a set of entities to mentions. In practice, collective techniques can be used alone or in tandem with individual techniques.
Graph is a convenient tool to represent interdependent entities. Very frequently, a graph is defined as nodes representing entity reference and edges representing relations between them. Some researchers include mentions as nodes (e.g. Han et al., 2011) but they can be replaced by scores associated with entity node as well.
