Study Of Green Construction Context-Awareness System Based On Ontology

Current word-wide has concentrated on the application of computer information technology to construction management and cause great attention between counties of world and academia. A new concept of green construction was proposed by construction industry under the premise of recent growing global ecological environment. Implementation of green construction standards could able to attain to good ecological and social benefits during the construction process. Ubiquitous computing as one of frontiers fields of computer technology researching, was applied to the green construction management and ensured the conduct of high-quality green construction that has important research and practical significance.This thesis that based on researching(studying)the existing context- awareness ubiquitous computing technology has focused on modeling green construction environment ontology and design appropriate scene of a context-awareness system. The main research contents include the following aspects:(1) To introduce of green building and green construction concepts and features, detail description of green construction management should pay attention to the construction process on two major aspects from resource conservation to environmental protection, and represent the importance of computer information technology in green construction management.(2) Deeply researching existed context-awareness ubiquitous computing of molding methods, comparison advantages and disadvantages among key-values models, markup scheme models, graphical models, object oriented models, logic based models and ontology based models. In particular, analysis three modeling methods based on ontology models.(3) According to ontology creation process definition the field of green construction, based two layers of green construction on the context ontology modeling, and validated the model. This thesis also used ontology OWL language to describe context-awareness model for green construction. (4) Proposed context-awareness system of green construction based on green construction ontology context models, detailed analysis of the system structure and each module function, but also implemented some modules of the system, illustrated that the system in practical applications could be played on good supplementary function on green construction management.Green construction context-awareness system advanced in this thesis is partly application valuable for achieving green construction management strategy.Creation of green construction ontology is a complex and cyclical process, with green construction technology constant progress, need to synchronously improve the existing body structure. While putting the green construction context-awareness systems into the real green construction environment to verify the system functions and expand system services to better meet to the demand for green construction management is the focus in the future research.
