Abstract
The active guide book is a context-aware information management system that uses a combination of spatial and keyword indexing to retrieve data. The system has three principal components:
-
A new document description language extends HTML to include facilities for tagging with spatial locations.
-
Retrieval uses two separate indexes - a segment tree is used for spatial indexing and an inverted file is used for keyword indexing.
-
A user interface allows queries involving keywords and location data to be expressed, and presents their results.
The system has been evaluated with the implementation of an interactive guidebook. The test data was drawn from existing Web pages describing the City of Cambridge in England, which were augmented with spatial information. A GPS system is used to provide the default location information for retrieval, but can be overridden with explicit coordinates.
