The Future: Marrying Ontology with XML : 

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 then define an ontology for that domain! We define an XML to code that information

Slide 7: 

To define an ontology for the domain of web pages 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

Slide 13: 

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.

Future Work : 

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.

Conclusions : 

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.
