Title	The Use of Ontology in Knowledge Intensive Tasks: Ontology Driven Retrieval of Use Cases
Author	Jongwoo Kim, Jordi Conesa, Balasubramaniam Ramesh
Keyword	Ontology, Use Case, Perceived Interaction, Cognitive Load, Self-Efficacy
Abstract	Use cases are commonly used to represent customer requirements during systems development. In a large software development environment, finding relevant use cases from a library of past or related projects is a complex, error-prone and expensive task. This study proposes an ontological methodology to support use case retrieval in an interactive manner. The architecture of a prototype system that implements this method-ology is presented. To evaluate whether the proposed approach can provide satisfactory results to users, this study develops a research model and hypotheses based on interaction theory. These hypotheses are empirically tested using a laboratory experiment which controls information filtering and perceived interaction. Our study suggests that a system which interacts with a user intelligently reduces cognitive load and increases self-efficacy and satisfaction.
