Semantic web approach for dealing with administrative boundary revisions: A case study of Dhaka City iii ABSTRACT Dhaka City is the capital of Bangladesh and boundary revisions of Dhaka city refers to the changes of Dhaka city administrative boundary or jurisdiction over time. Dhaka is growing very fast in terms of population and area. So, government is redefining city boundaries and also making big units into several parts for better city management. Now, the challenge is to deal with these changes of administrative regions that seem to be helpful to match with census record that comes out every ten to fifteen years. Dhaka city boundary revisions dataset contains data about the name of the administrative unit, type of administrative unit, year of establishment, year of data record, geometry of administrative unit defining the jurisdiction, type of revisions occurred in the administrative units, time of revisions and the number of subdivisions inside an administrative unit. This thesis aims to integrate Dhaka city boundary revision dataset using semantic web technology that preserves information about changes occurred in the Dhaka city boundary over time.
