The VERAKEY is a platform especially designed for construction projects using techniques and algorithms of natural language processing technology, big data association rule, deep learning, cloud computation, Internet of Things (IoT), and artificial neural networks. All functions provided by the platform are based on empirical data that can trace work patterns, suggest the optimal solutions, and facilitate communication and collaboration among all stakeholders of the construction projects.The study is to answer the demands to establish an interaction platform to integrate necessary modules for construction projects. The second-phase interaction platform uses big data and data mining techniques to connect all contract parties together for deep-insight management. The final phase creates interaction platform using DNN, cloud computing, natural language processing technology ,and IoT.The VERAKEY is constructed based on IoT, AI mobile device, and cloud computation integrated with over 20-year experience in Taiwan construction industry. The design concept is similar to a central kitchen that handles all details and yields intelligent outputs. The VERAKEY has been employed in 6 construction related companies with the total signed contract amount of over NTD 30 million up to now since 2016.
