Semantic matchmaking - i.e., the task of finding matching (Web) services based on semantic information - has been a prominent field of research lately, and a wide range of supporting tools both for research and practice have been published. However, no suitable solution for the visualization of matchmaking results exists so far. In this paper, we present the Matchmaking Visualizer, an application for the visual representation and analysis of semantic matchmaking results. It allows for the comparing of matchmaking approaches for semantic Web services in a fine-grained manner and thus complements existing evaluation suites that are based on rather coarse-grained information retrieval metrics.
