Meta-Portal

This project aims to develop a digital library system for distributed Geography learning objects and providing the essential tools to support problem-based learning. The research tasks include analyzing the content of those Geography related educational websites, constructing a community-driven review system for creating metadata and managing them, developing a object sharing mechanism to access remote learning object repositories making it possible to conduct advanced search and visualization over the distributed learning objects, and enabling the transduction of these educational content into students’ personalized project resources.

G-Portal

G-Portal is a Web-based digital library that collects metadata of geospatial and geo-referenced resources on the Web and provides digital library services to access them. It adopts a map-based interface as its primary point of access to visualize and manipulate the distributed geospatial and geo-referenced content. A classification-based interface is also provided to classify and visualize all resources. This interface is supported by a flexible classification language and the backend classification engine. G-Portal’s annotation capabilities allow users to contribute geospatial and geo-referenced contents as well as their associated metadata. Query of resources based on keywords in attributes and geospatial location are also supported.

GeogDL

GeogDL is a digital library of geography examination resources designed to assist students in revising for a national geography examination in Singapore. GeogDL's collection consists of past-year examination questions, solutions, related supplementary content and user annotations. GeogDL includes a mock exam tool to adaptively simulate of the actual geography examination, and a trend analysis tool to give an overview of the types of questions asked in previous examinations. GeogDL also provides a recommendation system to help students revise and prepare for exams using inputs from students’ performance and trend analysis of exam questions. User study has been conducted on GeogDL to improve its design.
