MSXD: A Model and a Schema for Concurrent Structures Defined over the Same Textual Data

摘要

This work aims at denning a model and a schema for mul-tistructured (noted MS) textual documents. Our objectives are (1) to describe several independent hierarchical structures over the same textual data (represented by several structured documents) (2) to consider annotations added by the user in each structured document and (3) to define weak constrains over the concurrent structures and annotations. Our proposal is based on the use of hedge (the foundation of RelaxNG). It is associated with an algebra defined on the structures and annotations of a document in order to specify constraints between them (by means of Allen's relations).
