Overview

Main Objective

The project objectives are: 1) Leveraging the power of knowledge graphs and web and cloud technologies to develop a comprehensive knowledge graph framework that offers seamless access to multiple geohazard monitoring data repositories and provides efficient search, processing, visualization and analytical capabilities to end users; 2) extracting meaningful insights and relationships from the integrated datasets by leveraging the semantic capabilities of knowledge graphs to reduce the risks and uncertainties related to geohazards management in natural gas and hazardous materials pipelines; and 3) empowering stakeholders to make informed decisions regarding hazard assessment, early warning systems, and disaster response planning by providing a unified view of the data and developing methodologies to capture the essential decision-related information.

Public Abstract

Project Description: This project envisions developing a graph database system and constructing knowledge graphs to provide an integrated and comprehensive knowledgebase of geohazards related data, which can be used in assessing the current condition of pipelines and predicting potential issues threatening the integrity of pipelines. The project objectives are: 1) Leveraging the power of knowledge graphs and web and cloud technologies to develop a comprehensive knowledge graph framework that offers seamless access to multiple geohazard monitoring data repositories and provides efficient search, processing, visualization and analytical capabilities to end users; 2) extracting meaningful insights and relationships from the integrated datasets by leveraging the semantic capabilities of knowledge graphs to reduce the risks and uncertainties related to geohazards management in natural gas and hazardous materials pipelines; and 3) empowering stakeholders to make informed decisions regarding hazard assessment, early warning systems, and disaster response planning by providing a unified view of the data and developing methodologies to capture the essential decision-related information.

Anticipated Results: Using this prototype graph-based knowledge platform, geohazard monitoring data from various sources can be organized and visualized in a way that enables heuristic-based knowledge exploitation, alleviating the need for manual and usually complex task of knowledge discovery from various sources of heterogenous data. The knowledge presented in this platform is more transparent, interpretable and easy to understand which will in turn facilitate more efficient, timely and consistent decisions, where all stakeholders are well aware of the requirements and expectations. Pipeline operator, regulators and policy makers can use this tool for mapping hazard prone land surfaces, monitoring terrain deformation, identifying indicators of geohazards, assessing the current condition of pipelines and predicting potential issues threatening the integrity of pipelines. Consequently, it can improve pipeline integrity monitoring and management, reduce the number of over- and under-regulated operations, and reduce the number of potentially harmful non-compliance incidents.

Potential Impact on Safety: Using Knowledge graphs to integrate geohazard monitoring data collected from various sources, makes it possible to discern cyclic behavior, temporal variations, or changes in hazard intensity, providing the necessary situational awareness around particular hazards. By harnessing this fused source of information and using advanced data driven techniques, operators and authorities can conduct more robust and trustworthy analyses on geohazards and identify precursors or anomalies that may indicate the onset of a hazard. Additionally, the integrated knowledgebase enables pipeline authorities to review and potentially revise policies and guidelines for geohazard management, risk assessment/mitigation, and emergency response. These revisions can result in improving regulatory governance by addressing over- and under-regulated operations and reduce the number of potentially harmful non-compliance incidents
