2. Overview of the talk Why Manipulate Web Pages? Low Level Manipulation of Web pages What are the Options for Web Page Manipulation? – By Hand – Transcoding – Automated Re-authoring Table of Content Summarization Hybrid Web Content Delivery Issues Commercial Web Summarizer Conclusion and future work

3. Why Manipulate Web Pages? Mobile viewing allows keeping in touch with the rest of the world while on the move To summarize web content to help in rapid viewing Often there is a demand for alternative browsing, such as the use of voice Universal email accessibility is a problem of web page manipulation Document conversion and archiving

4. Low Level Manipulation of Web pages Structural analysis of the web by decomposition and subsequent processing Extraction and processing images play a large part in this process. Detection of specific structures, such as tables, within web pages has been an active research problem. Using forms within the narrow display area is another challenge.

13. Where are we Heading? Devices are becoming powerful, screen resolution is improving Some devices are offering landscape view Powerful Zooming technology is coming Thumbnail Image Processing VNC

14. Conclusions A very concise review of the research being carried out in manipulating web documents for accessing and viewing on small screen devices. It is neither exhaustive nor is aimed to be. It is hoped that this will offer a starting point of future research in this area by pointing to important works that are being conduced at the present.
