We have explained that question answering is a more
effective and natural way of getting knowledge on the web
than document search. To implement effective AQA systems,
structured data sources such as databases should be available
to retrieve relevant data for answering. The web is currently
a space of unstructured data, so it’s not appropriate for
automated question answering. We showed that semantic web
services is appropriate for automated question answering on
the web; semantic web services builds up a structured data
store which is practically of infinite volume on the web. Also
semantic web services provides a standardized framework of
representing data semantically, of publishing and discovering
services dynamically, and of consuming the services. Consequently,
by building up data sources for automated question
answering systems as a set of semantic web services, we’ll be
able to realize effective automated question answering systems
for the web that can discover new data sources and integrate
new data into their own knowledge space. We conjecture that
automated question answering systems like this will shed some
light on the future intelligent systems in the open space.
