Organized around the concept of improving Home improvement, Wise Cae Technologies is develping an app. desitgned to increase market efficiency among homeowners and home improvement contractors. The firm suggests that the knowledge harvesting and case-based estimation technologies from this project can be applied to a variety of industries in todays knowledge economy, particularly those benefiting from socially cultivated knowledge repositories. The firm is exploring the technical feasibility of delivering accurate project estimates for the home improvement market by combining a case-based reasoning approach with crowd intelligence. First, the project develops and validates a cost estimation methodology that applies case-based reasoning to a knowledge repository built and evolved by social efforts, through a cycle of knowledge harvesting, organization, augmentation and calibration. Second, the project will develop techniques in focused crawling, multi-document summarization, cased-based reasoning, and advance the research in these fields. Third, the project will develop and evaluate novel, mobile interfaces for knowledge elicitation, augmentation and calibration.
