Coherence in heterogeneous texts from sentences to sequences of sentences

الملخص EN

Text coherence is one of the seven criteria of textuality which has relation with the perception of text content by the reader / listener in its appropriate context.

a text is considered coherent when the sentences of which it is composed, are semantically related.

the aim of this article is to identify some aspects of coherence in heterogeneous texts; it means semantic and pragmatic relations between typed sequences of sentences, as defined by Jean-Michel Adam, in both theoretical and practical studies.

the results showed that it is possible to study coherence in heterogeneous texts through the analysis of their sequential structure.

we also found that sequences of different types (narrative, descriptive, argumentative, expository or conversational) can be related semantically through relations such as repetition, individual identity, moving from general to particular and whole-part relations.
