Developing Web-based Search Portals on Birds for Different Target Groups

This paper presents the experiences and interim results from the ongoing iterative development and testing of four distinctive search portals on birds. The search portals are developed within the EU STERNA project and address different target user groups. Based upon specific use case scenarios the search portals are tested and validated in four specific phases, applying three different testing methods: WAMMI online evaluation, focus group evaluation and task-based usability tests. The paper introduces the four search portals, depicts the testing methodology and presents the first results from the ongoing user validation process.
