Title: “Design Principles for the Extraction of Context-Aware Information”
In the course of normal business operations, organizations generate and store transactional data to cover different tactical needs. These data may serve different purpose and the information needs of a user vary based on the user’s background and/or task at hand. Our goal is to propose design principles in order to abstract context information from stored data. To do so, we propose two different case studies in a healthcare setting. In the first case study we use a domain-specific ontology to abstract context-aware information from structured data. In the second case study we use knowledge discovery techniques to extract context-aware information from unstructured data. The results of these studies have implications both to theory and practice. From a practical standpoint, context-aware systems reduce the irrelevance of the information presented to the user, allowing for effective use of resources, which are critical in healthcare. From a theory perspective we validate a domain-specific ontology and we extend the concept of information modularity by adopting ontological principles to cover different information needs.
