4. Survey of types of coreference with respect to the t-lemmas of the coreferring nodes
Prev	Chapter 9. Coreference	Next

The different types of coreference (textual and grammatical) with regard to the t-lemmas of the coreferring nodes are summarized in Table 9.5, "Types of coreference". The table only lists the t-lemmas (including t-lemma substitutes) that are relevant for the representation of coreferential relations. Hence, the table does not include e.g. the t-lemmas #Forn;, #Idph;, #Neg; etc.

The X symbol in the column with the heading "Surface structure of the sentence" means that the given node is not present in the surface structure of the sentence.

Table 9.5. Types of coreference

Type of coreference		Surface structure of the sentence	t-lemma	Representation of coreference
Textual	Explicitly coreferred element	3rd person pronoun (on)	`#PersPron`	`coref_text.rf`
		the pronoun ten used as a noun	ten
		X	`#PersPron`
	Segment	certain uses of the pronoun ten used as a noun	ten	`coref_special`=`segm`
	Segment	3rd person pronoun (on)	`#PersPron`	`coref_special`=`segm`
	Exophora	the pronoun ten used as a noun	ten	`coref_special`=`exoph`
		3rd person pronoun (on)	`#PersPron`
		X	`#PersPron`
Grammatical	Reflexive pronouns	personal and possessive reflexive pronouns (se, svůj)	`#PersPron`	`coref_gram.rf`
	Reciprocity	X	`#Rcp`
	Relative elements	- relative pronouns in relative clauses (který, jaký, jenž, co) - relative adverbs in relative clauses (kdy, kde, kam, odkud) - the connective což	který, jaký, co kdy, kde co
	Coreference with verbal modifications that have dual dependency	X	- `#Cor;` (in place of the non-expressible subject of a non-finite verb form) - `#Cor;` (in place of the non-expressed subject of a finite verb form in a predicative-complement clause)
	Control	X	`#Cor`
	Quasi-control	X	`#QCor`
Special types of coreference	Unspecified Actor	X	`#Unsp`	NO
No coreference	General argument	X	`#Gen`	NO
	Ellipsis of the governing node	X	`#EmpNoun`
	Ellipsis of the governing node	X	`#EmpVerb`
		the pronoun ten	ten
No coreference indicated		1st and 2nd person pronouns	`#PersPron`	NO
		pronominal adverbs (tam, sem, tak etc.)	tam, tady, tak	NO
		X	`#Oblfm`	NO
