7. IEEE BigData Overview October 9 2013 9/29/13 Definitions and Taxonomies Subgroup 7 The focus is to gain a better understanding of the principles of Big Data. It is important to develop a consensus-based common language and vocabulary terms used in Big Data across stakeholders from industry, academia, and government. In addition, it is also critical to identify essential actors with roles and responsibility, and subdivide them into components and sub-components on how they interact/ relate with each other according to their similarities and differences. Tasks For Definitions: Compile terms used from all stakeholders regarding the meaning of Big Data from various standard bodies, domain applications, and diversified operational environments. For Taxonomies: Identify key actors with their roles and responsibilities from all stakeholders, categorize them into components and subcomponents based on their similarities and differences

8. IEEE BigData Overview October 9 2013 9/29/13 Data Science Definition (Big Data less consensus) Data Science is the extraction of actionable knowledge directly from data through a process of discovery, hypothesis, and analytical hypothesis analysis. A Data Scientist is a practitioner who has sufficient knowledge of the overlapping regimes of expertise in business needs, domain knowledge, analytical skills and programming expertise to manage the end-to-end scientific method process through each stage in the big data lifecycle. 8 Big Data refers to digital data volume, velocity and/or variety whose management requires scalability across coupled horizontal resources

9. IEEE BigData Overview October 9 2013 9/29/13 Reference Architecture Subgroup 9 The focus is to form a community of interest from industry, academia, and government, with the goal of developing a consensus-based approach to orchestrate vendor-neutral, technology and infrastructure agnostic for analytics tools and computing environments. The goal is to enable Big Data stakeholders to pick-and- choose technology-agnostic analytics tools for processing and visualization in any computing platform and cluster while allowing value-added from Big Data service providers and the flow of the data between the stakeholders in a cohesive and secure manner. Tasks Gather and study available Big Data architectures representing various stakeholders, different data types, use cases, and document the architectures using the Big Data taxonomies model based upon the identified actors with their roles and responsibilities. Ensure that the developed Big Data reference architecture and the Security and Privacy Reference Architecture correspond and complement each other.

12. IEEE BigData Overview October 9 2013 9/29/13 Security and Privacy Subgroup 12 The focus is to form a community of interest from industry, academia, and government, with the goal of developing a consensus secure reference architecture to handle security and privacy issues across all stakeholders. This includes gaining an understanding of what standards are available or under development, as well as identifies which key organizations are working on these standards. Tasks Gather input from all stakeholders regarding security and privacy concerns in Big Data processing, storage, and services. Analyze/prioritize a list of challenging security and privacy requirements from ~10 special use cases that may delay or prevent adoption of Big Data deployment Develop a Security and Privacy Reference Architecture that supplements the general Big Data Reference Architecture

This includes setting standardization and adoption priorities through an understanding of what standards are available or under development as part of the recommendations. Tasks Gather input from NBD subgroups and study the taxonomies for the actors roles and responsibility, use cases and requirements, and secure reference architecture. Gain understanding of what standards are available or under development for Big Data Perform a thorough gap analysis and document the findings Identify what possible barriers may delay or prevent adoption of Big Data Document vision and recommendations
