Purpose - By providing interoperability users can be supported in sharing and reusing vocabularies
and knowledge. Ontology alignment plays an important role in the context of semantic interoperability.
Usually ontology alignment tools generate results that are difficult to understand or assess. In order to
enable users to check and improve alignment results and to understand their consequences information
visualization techniques are used. The purpose of this paper is to discuss the relevant quality aspects in
ontology alignment as well as current activities and available tools.
Design/methodology/approach - Based on a literature study quality measures for ontology alignment
identified and requirements for visual ontology alignment are defined. As a proof of concepts a
prototype called AlViz was developed.
Findings - Information visualization offers appropriate methods for the assessment of ontology
alignment results. Different levels of detail and overview help users to navigate and understand the
alignments. The assessment of semi-structured resources by users involves learning activities. The
neighborhood of the entity under investigation bears relevant semantic information. Therefore,
assessment may include crisscrossing acquisition of knowledge representations and their semantics.
Originality/value - Along a comprehensive framework alignment assessment tasks are identified and
visualization tool is introduced and applied which aims at making ontology alignment results
manageable and comprehensible.
