W3C Incubator Group Report: Common Web Language
Hiroshi Uchida, Toshio Yokoi (et al., eds), Incubator Group Final
Report (03)
Members of the W3C Common Web Language Incubator Group have
published a Final Report. Currently almost all web pages are
written in English. It is convenient for English speaking people
but it is not for non-English speaking people, and those people
are the majority in the world. Those people cannot get information
easily, because it is not written in their mother tongue. Recently
machine translation facilities are equipped in the web, but it is
not the solutions. Machine translation has a problem of quality
and coverage of languages. HTML tags give information on structure
of web documents, but they do not give semantic information on
each words nor sentences in documents. It means HTM tags
information is insufficient to intellectually utilize contents of
web pages. The RDF and OWL have a framework to give semantic
information but they do not have standard vocabulary to describe
web contents. The goal of the Common Web Language is to allow the
exchange of information through the Web and also for enabling
computers to process information semantically. CWL allows people
to describe contents and meta-data of Web pages written in natural
language; the language seeks to lower language barriers and to
facilitate the automatic extraction of information from Web pages.
The CWL is a graph language of semantic hyper directed graph, a
node represents a concept, an arc represents a relation between
nodes and a node can be annotated by attributes. This CWL can be
expressed in three languages UNL, CDL and RDF/OWL. The same
information in CWL can be described in each language but in
different manner. The CWL.unl is a language based on UNL. The
CWL.cdl is a language based on the CDL. The CWL.rdf is a language
based on RDF/OWL. Three different types of representations of CWL
allow different way of treatment of the same information
described. The CWL.unl is for multilingualism, The CWL.cdl has
compatibility with semantic computing systems for semantic
computing, The CWL.rdf is for working with various data navigation
and aggregation systems (like SPARQL). Compatibility among
expressions in UNL (CWL.unl), CDL (CWL.cdl), and RDF is
guaranteed. (04)
