Travel Analysis Framework

• It is based upon the model of real world travel.
• It is comprised of two stages

• Identifying travel objects and creating a travel
  object inventory
• Classifying each travel object in the created
  inventory.

Evaluation of the Framework
Demonstrated that the analysis process
encapsulated in the framework is consistent and
systematic, therefore can be used as the basis of
a mobility support tool.

A Mobility Support Tool

• Identify travel objects- a Web page will be
  inspected for extracting travel objects
• Classify- the role (s) of the extracted travel
  objects will be identified
• Annotate- the extracted travel objects will be
  annotated
• Transform- the page will be transformed into
  another form so that travel objects can fulfill
  their intended roles.
