In this paper, we present an approach to ontology querying for the purpose of supporting the semantic annotation process. We present and evaluate two algorithms, (i) a baseline algorithm and (ii) a graph-based algorithm based on the bag-of-words text representation and PageRank. We evaluate the two approaches on a set of semantically annotated geospatial Web services. We show that the graph-based algorithm significantly outperforms the baseline algorithm. The devised solution is implemented in Visual OntoBridge, a tool that provides an interface and functionality for supporting the user in the semantic annotation task. The improvement over the baseline is also reflected in practice.
