  The semantic mapping problem is probably the main obstacle to
computer-to-computer communication. If computer A knows that its concept X is
the same as computer B's concept Y, then the two machines can communicate. They
will in effect be talking the same language. This paper describes a relatively
straightforward way of enhancing the semantic descriptions of Web Service
interfaces by using online sources of keyword definitions. Method interface
descriptions can be enhanced using these standard dictionary definitions.
Because the generated metadata is now standardised, this means that any other
computer that has access to the same source, or understands standard language
concepts, can now understand the description. This helps to remove a lot of the
heterogeneity that would otherwise build up though humans creating their own
descriptions independently of each other. The description comes in the form of
an XML script that can be retrieved and read through the Web Service interface
itself. An additional use for these scripts would be for adding descriptions in
different languages, which would mean that human users that speak a different
language would also understand what the service was about.
