Definition: enumerative structures (ESs in short) are segments resulting from a text organisation strategy whereby text elements are presented as having equal status with regard to a specific interpretation criterion (co-enumerability criterion). They are characterised by an internal structure involving the following sub-segments:

1. a trigger (optional): segment which introduces the enumeration ;
2. several items: segments which make up the enumeration (at least two items must be identified for a structure to be annotated) ;
3. a closure (optional): segment which summarises or closes the enumeration.

The annotated objects are :

• the trigger (if there is one)
• the items (at least two)
• the closure (if there is one)
• the enumeraTheme (if there is one), i.e. the expression specifying the co-enumerability criterion
• the cues associated with the four preceding objects
• finally the enumerative structure itself, i.e. the segment which contains these objects.

Definition: topical chains (TCs in short) are a specific form of cohesive chains, i.e. topically homogeneous segments composed of sentences containing topical co-referential expressions.

The annotated objects are:

• a segment called "segment"
• the associated topical continuity cues.

NB: TCs may contain sentences which are not topically connected (e.g. comments, illustrations, etc.) if they occur between connected units.
