The document discusses mining legacy code for potential web services. It proposes an architecture that combines information retrieval tracing with structural matching of web service definitions to existing code methods. The approach uses textual and structural matching based on an existing algorithm, with query expansion using WordNet. It evaluates precision and recall of the structural matching approach for different threshold values. Current work aims to improve recall by incorporating relationships between terms and concepts using ontologies or latent semantic indexing, and by using code slicing to extract features to export as services.
