Case-Based Service Requests Interpretation

Abstract

A Case-Based Service-Request Interpretation (CBSRI) method is proposed to cope with the problem of how to extract service requests intention from the user’s entered strings. Based on the proposed approach, the user’s vague and imprecise service request will be extracted and mapped to a set of computer understandable and computable goal models. These goal models are elicited from the requirements specifications and used to represent the system capabilities to satisfy user’s service requests. The CBSRI can reuse previous interpretation experience to interpret newly received service requests. The intention interpretation knowledge is stored in a case-base and the intention interpretation is based on the process of case retrieval and adaptation. A rule-based approach, a statistical-based approach, and the case-based approach are implemented to examine the efficiency of the proposed approach.
