Ontology-based construction knowledge retrieval system

Managing knowledge effectively is critical to the competitive power of a company. Knowledge is used as an important resource in many industrial areas, and so it follows that there is a growing interest in knowledge management within the construction industry. Yet because of the unique characteristics of construction knowledge created during projects, there are limitations to its capture and reuse. The knowledge produced during construction projects is project-oriented, experiential, and context specific; due to these characteristics, the reuse of knowledge is difficult. In this research, research team focus on capturing and identifying the characteristics of construction knowledge, then propose a method for applying these characteristics to the development of an ontology-based construction knowledge retrieval system. Moreover, research team developed a system prototype that applies ontology in suggesting related search words during the search process and validated the effectiveness of the prototype in terms of precision and recall rate. By applying the prototype, the precision and recall rate was improved by approximately 10 similar to 30%.
