The Future Marrying Ontology with XML

• We assume that we have layout information for a
  web page
• What do we do then?
• How do we use this information?
• How do that information help us in getting better
  re-authoring solutions?

We define an XML to code that information
We then define an ontology for that domain!
7
What is Ontology and How do We Define it?
Ontology establishes a joint terminology between
members of a community of interest.
These members can be human or automated agents.

• A list of elements
• Concept hierarchy
• Concept association
• Rules or axioms

• To define an ontology for the domain of web pages

What is the Advantage of using Ontology?

• It improves the quality of the output in many
  ways.
• It becomes possible to capture the contextual
  relationship among various components within the
  document
• It leads to better understanding of the
  information contained within the document.
• This additional information can be used in other
  processes, such as document categorization and
  contextual search.

14
Future Work

• It is assumed that the future of mobile browsing
  lies in the adoption of semantic web technology.
• Before that realizes, the proposed approach
  offers a workable compromise to generate high
  fidelity re-authored web pages.
• This is an exploratory paper offering a specific
  pathway to the future of web page re-authoring
  provided accurate layout information is
  available.
• Currently, it is beyond the capability of any
  algorithm to achieve this level of accuracy.
  However, approximations to that accuracy are
  attainable and even practical. It will be
  interesting to discuss other possibilities in
  this space.

15
Conclusions

• Some ideas about how to produce better web page
  re-authoring solutions by using linguistic
  knowledge and ontology assuming accurate layout
  information for web pages is available.
• It is shown that such an approach will produce
  high quality intelligent summary for web pages
  allowing fast and efficient web browsing on small
  display handheld devices.
