Role of ontologies in beach safety management analytics systems

Download to read offline

Events at public beaches are one of the most popular recreational activities of local communities and international visitors in all places around the world. Amongst others, the beach safety management in protected areas needs support for continuous analysis and decision making on incidents at the beach areas. There is a lack of available standard models to assist data scientists to represent analytics models including different spheres of interplay domain variables related to beach safety management. Using the Design Science Research Methodology (DSRM), we developed ontological models that facilitate a unified representation and maintenance analytics models. We contribute to the ontology design theory for analytics models underlying analytics systems for the beach safety management domain. Our research findings can be used in the general class of ontology design problem for analytics systems in practice.

Role of ontologies in beach safety management analytics systems

  1. 1. Role of Ontologies in Beach Safety Management Analytics Systems (Paper order: 1783) 1
  2. 2. • Outline • Research context • Research problem and objective • Research methodology • Lessons learned (key takeaways) • F&Q 2
  3. 3. • Public beaches are one of the most popular recreational activities of local communities • a vibrant public space for locals and international • Life-threatening injuries • International Life Saving Federation (ILSF) reports that 1.2 million people around the world annually lose their lives due to drowning in open water such as beaches, sea, lakes, and rivers. • unfamiliarity with surfing conditions • poor swimming skills • weather condition • disorientation in coastal areas 3 Research context
  4. 4. • Smart Beaches (IoT & Analytics enabled) • Beach safety management agencies leverage a wide range of information technologies such as IoT (Internet of Things) devices, drones, wearable sensors, outdoor cameras, and mobile applications • Continuous monitoring of beach space to detect hazards and alarm risks in a real-time fashion • Massive data (aka. Big Data) collected from these technologies 4 Research context
  5. 5. Analytics models(Watson 2014) • Descriptive analytics models • Sum of drowning • Average of shark attacks per month • Average of beachgoers • Example: bar charts, pies • Predictive analytics • Project future possibilities to answer questions • what type of incidence is likely to happen at the beach in a public holiday? • Example: regression and machine learning • Prescriptive analytics • Decision making • What actions should be taken to avoid drowning incidence during summer break? • Example: simulation and decision models 5 Analytics models, i.e., descriptive, predictive, prescriptive Beach safety management domain Research context
  6. 6. • Knowledge gaps in developing Analytics Information Systems (in smart beach domain) •Communicative and knowledge intensive exercise •What are incorporating variables informing analytics models, especially beach safety management domain? •Efficient and consistent knowledge flow about analytics models among data scientists •An overarching view that can pull together the various domain variables describing analytics models •Also called “Data and model disparity problem” in analytics Analytics models (descriptive, predictive, prescriptive) Analytics systems Beach safety management domain Data science team Research problem and objective
  7. 7. • A potential solution: Ontologies (e.g., domain conceptualisation) • A systematic explanation of being (Kishore 2004) • Interoperability, and bridging knowledge among stakeholders • Structure and codify knowledge about concepts, relationships, and axioms/constraints in a specific context • Computational format, competency questions (CQ) • CQ, what risk factors occur at beach? • is represented by: What [V1] [OPE] [V2]? • V1, i.e., risk factors and V2, i.e., beach, are variable expressions • OPE, i.e., occur, is an object property expression • Research objective • To develop an ontology for beach safety management domain to inform data scientists of operational variables and data to incorporate into analytics models. 7 Analytics models (descriptive, predictive, prescriptive) Analytics systems Beach safety management domain Data science team Research problem and objective
  8. 8. • Research methodology • Design science research methodology-DRSM (Gregor and Hevner 2013) • Smart beach ontology artifact • Design cycles and iterative artefact refinements 8 Research methodology
  9. 9. • Sample Smart Beach Ontology (SBO) artifacts • Ontologies that capture knowledge about analytics models for the beach safety management domain • Domain variables and relationships 9 Research methodology – design cycles
  10. 10. 10 Instead of struggling to understand analytics mode in ad-hoc way, Smart Beach Ontology (SBO) artifacts act as a guidance or conceptual model to inform data science team about what variables are and how they might be related.. Research methodology – design cycles Data science team
  11. 11. 11 Smart Beach Ontology (SBO) sample artifacts Research methodology – design cycles
  12. 12. 12 Competency Question 2 (CQ2). What incidents happened at Bondi beach? Domain variables – captured in ontology – are incident, beach (Bondi) Research methodology – design cycles
  13. 13. 13 Research methodology – design cycles
  14. 14. 14 Smart Beach Ontology as a point of reference for transforming, either manual or automatic, analytics queries/requirements to analytics information systems Research methodology – design cycles
  15. 15. • Key takeaways in designing ontologies for analytics systems • Trade-off among ontology design principle • Design principles: completeness, correctness, expandability, conciseness, consistency, clarity • For example: generic and less-detailed ontology vs. a comprehensive one versatile • Reciprocal benefit • Whilst SBO narrows its focus on the standardization and integration of analytics models at beach safety agencies, analytics models can help to verify knowledge captured by the ontology • Noisy variables might be removed from the ontology after some analytics model development • Variable drift • Rapidly changing environments of new type of incidents, new rescues actions, and new visitor hazardous behaviors at beach space inevitably results in a change of meaning for variables • The notion of Rescue can be completely changed from human lifesaver to fully automatic drone lifesaver 15 Lessons learned (key takeaways)
