Welcome to CIS-OKN

The Civil Infrastructure Systems Open Knowledge Network (CIS-OKN) data inventory collects heterogeneous types of data to (1) extract deep information (e.g., about infrastructure system conditions) from unstructured sources, (2) link and fuse data from disparate sources, in different formats (structured and unstructured), and with different levels of technical and descriptive detail for supporting further data analytics and data-driven decision making, and (3) query and learn from these integrated data/information to enable deeper analysis and knowledge discovery.
