This work presents an improvement on a novel Selection Method to develop applications in the context of the Service-Oriented Computing paradigm. We have defined an Interface Compatibility procedure to assess Web Services by exploring the available information from WSDL documents. Such information involves data types from return, parameters and exceptions, and identifiers from parameters and operation names. The lexical database WordNet was originally used as a semantic basis to assess terms from identifiers. In this paper we use the DISCO database as an alternative, to evaluate the independence of the approach w.r.t. the semantic basis. We made a comparative analysis through different experiments with a data-set of 465 real-life Web Services and measured the results using metrics from the Information Retrieval field.
