Information Mediation

Information search, navigation, exploration, visualisation COTS

Search Engines— Keyword based search

— Hierarchical subjects

Problem— Boolean expressions

— Guess subject of interest

— Information exploration and encountering

Information Visualisation Attributes of information (date, author, location,...) Attributes of search results (ranking, number of keywords, access,...)

Latent Relations temporal or spatial account

spatial relationships as one deduction source for information mediation

Objective

Use spatial account of information

Map based interface Information related to named regions on map

Cartography Figure showing an object of interest

Map signalises existence of referenced information Categorization of information in hierarchical subjects Meta data describing maps, regions, information sources,

etc. Views of information spaces

Unter semantischen Netzen versteht man die Darstellung und Ableitung von Beziehung zwischen Informationsobjekten. Diese Abhängigkeiten lassen sich beispielsweise als gerichteter Graph darstellen, wobei in Abhängigkeit vom Relationstyp auch Vererbung und logische Ableitungen möglich sind.

Semantische Netze basieren auf der Idee der sogenannten Concept Maps:

“Concept-maps ("Begriffslandkarten"/Begriffsnetzdarstellungen) sind graphisch-verbale Darstellungen strukturierter Wissensinhalte. [JÜNGST]

Der Begriff der Concept Maps kommt ursprünglich aus dem Bereich der Lerntheorie und wurde von Joseph Novak als Mittel zur Visualisierung des Wissens eines Menschen entwickelt [ABRAMS].

Die von Novak beschriebene Concept Map wird als Baum von Konzepten dargestellt, der ausgehend von einem beliebigen Wurzelkonzept (Begriff) in immer spezifischere Konzepte aufgeteilt wird. Die Knotenkonzepte stehen über Linkwörter in Beziehung. Konzepte werden mit Kästen umgeben, Linkwörter auf die knotenverbindenden Pfeile geschrieben. Mit dieser schlichten Darstellung können sehr komplexe Ideen und Fakten sehr einfach beschrieben werden, wobei auch vereinfachten Darstellung von Programmabläufen [KREMER].

Functionalities I

Visualization of maps/interaction with maps Display of vector maps including Java drawings Display and selection of different layers Display of sensitive areas on mouse-over events Zooming and panning Display of longitudes and latitudes, zooming factor, size of drawings

Display of spatially related information Popup-menus for the selection of categories and spatially related information Launching of viewers for the visualisation or download of information (e.g.,

plug-ins, external viewers, HTML Windows)

Groupware Creation, connecting to and closing of sessions Joined editing (e.g. drawing on maps) Exchange of messages (chat)

Accomplishments of GeoPro

Smart Maps Information visualisation, exploration, confirmation Search with “image of location in mind”, “walking on maps” Graphical access by named regions

Ease of use Inexperienced users, systems with no or uncomfortable keyboards

Views on information spaces Maps - subjects - information sources

Various application domains Cartographic maps, CAD, blue prints, photos

On top functions docked Groupware Bathymetry

Database population with little GIS knowledge

Conclusion

Future Plans Intelligent assistance for database population Enhanced search capabilities

— Search by text for information sources and for subjects

— Selection of several regions

Animation— GPS, changes over time

Envision Employing special GIS functions (neighbourhood, distance) Foster market for GIS Use of GIS for other knowledge asset management means
