Annotating and Visualizing Location Data in Geospatial Web Applications
17th International World Wide Web Conference (WWW-2008), Proceedings of the First International Workshop on Location and the Web (LocWeb 2008)
This paper presents the IDIOM Media Watch on Climate Change
(www.ecoresearch.net/climate), a prototypical implementation of
an environmental portal that emphasizes the importance of location
data for advanced Web applications. The introductory section
outlines the process of retrofitting existing knowledge repositories
with geographical context information, a process also referred to
as geotagging. The paper then describes the portal’s functionality,
which aggregates, annotates and visualizes environmental articles
from 150 Anglo-American news media sites. From 300,000 news
media articles gathered in weekly intervals, the system selects
about 10,000 focusing on environmental issues. The crawled data
is indexed and stored in a central repository. Geographic location
represents a central aspect of the application, but not the only
dimension used to organize and filter content. Applying the concepts
of location and topography to semantic similarity, the paper
concludes with discussing information landscapes as alternative
interface metaphor for accessing large Web repositories.
