The advantages and positive effects of tightly coupled interface components on search performance have been documented in several studies. This paper focuses on the implementation of tightly coupled views within the Media Watch on Climate Change, an interactive Web portal (www.ecoresearch.net/climate) combining a portfolio of semantic services with a visual exploration and information retrieval interface. The portal builds contextualized information spaces by (a) enriching the content repository with spatial, semantic, and temporal annotations, and (b) applying semi-automated ontology learning to the repository yielding a controlled vocabulary that helps structuring the stored information. Different portlets visualize aspects of the contextualized information spaces, providing the user with multiple views on the available information. Currently, synchronized semantic maps, domain ontologies, geographic maps, tag clouds and real-time information retrieval agents suggesting similar topics and nearby locations, provide users with important context information, facilitate the access to complex datasets, and help users navigate large collections of Web documents.
