Retrieval over Conceptual Structures

摘要

The aim of the research conducted is to investigate how the knowledge in Ontologies can be used to acquire and refine the weights required in Case Retrieval Networks (CRNs). CRNs are designed to perform efficient retrieval processes even in large case bases but they lack from the flexibility and over restrict the circumstances under which the cases are retrieved. We investigate how ontologies can be used to relax these restrictions. We propose a retrieval method where the cases are embedded in a CRN but the weights are dynamically computed using the knowledge from the domain ontology and from the query description.
