※automatic document generation

²        the semantic web is envisioned as an extension of the current web where,in addition to being human-readable using www browsers,documents are annotated with meta-information.this meta-information defines what the information(document) is about in a way whitch is machine processable.
the explicit representation of meta-information accompanied by domain theories (i.e.ontologies),will enable a web that provides a qualitatively new level of service.
