Using case-based reasoning for creating semantic web services: An infrawebs approach

The paper presents an approach for using case-based reasoning to facilitate the task of creating complex logical description of a semantic Web service capability according to WSMO Framework. The case-based memory provides the service designer with descriptions of existing semantic Web services similar to her request represented by a query form. Such a form allows expressing the user's intentions on how the different part of the service under design should look like using both natural language and ontology-based words. Some possible approaches for measuring similarity between a query (a description of a problem to be solved) and a case (a description of another, already solved problem) are discussed and several similarity functions are proposed. All of them are asymmetrical, which is argued by a principal difference in the amount of known features used for describing objects to be matched. Evaluation of similarity is based on a specific, non-logical representation both of a query and a service. Such a representation allows an arbitrary WSMO object to be treated as a specially constructed text document.
