"Big Data" is term heard more and more in industry – but what does it really mean? There is a vagueness to the term reminiscent of that experienced in the early days of cloud computing. This has led to a number of implications for various industries and enterprises. These range from identifying the actual skills needed to recruit talent to articulating the requirements of a "big data" project. Secondary implications include difficulties in finding solutions that are appropriate to the problems at hand – versus solutions looking for problems. This presentation will take a look at Big Data and offer the audience with some considerations they may use immediately to assess the use of analytics in solving their problems. The talk begins with an idea of how big "Big Data" can be. This leads to an appreciation of how important "Management Questions" are to assessing analytic needs. The fields of data and analysis have become extremely important and impact nearly all facets of life and business. During the talk we will look at the two pillars of Big Data – Data Warehousing and Predictive Analytics. Then we will explore the open source tools and datasets available to NATO action officers to work in this domain. Use cases relevant to NATO will be explored with the purpose of show where analytics lies hidden within many of the day-to-day problems of enterprises. The presentation will close with a look at the future. Advances in the area of semantic technologies continue. The much acclaimed consultants at Gartner listed Big Data and Semantic Technologies as the first- and third-ranked top technology trends to modernize information management in the coming decade. They note there is an incredible value "locked inside all this ungoverned and underused information." HQ SACT can leverage this powerful analytic approach to capture requirement trends when establishing acquisition strategies, monitor Priority Shortfall Areas, prepare solicitations, and retrieve meaningful data from archives.

This presentation will describe a new literacy: “data literacy”, the analogy with computer literacy, and reasons why this skillet will soon be as essential to all professionals as computer literacy is today. It will address the advent of decision making as the key managerial activity and the resulting democratization of AI and analytics. The presentation will address issues of mindset, as well as skillset, and the ways to acquire a basic level of data literacy to derive value from AI and ML assisted processes in one’s daily tasks.

Abstract—Recently the world is experiencing an deluge of data from different domains such as telecom, healthcare and supply chain systems. This growth of data has led to an explosion, coining the term Big Data. In addition to the growth in volume, Big Data also exhibits other unique characteristics, such as velocity and variety. This large volume, rapidly increasing and verities of data is becoming the key basis of completion, underpinning new waves of productivity growth, innovation and customer surplus. Big Data is about to offer tremendous insight to the organizations, but the traditional data analysis architecture is not capable to handle Big Data. Therefore, it calls for a sophisticated value chain and proper analytics to unearth the opportunity it holds. This research identifies the characteristics of Big Data and presents a sophisticated Big Data value chain as finding of this research. It also describes the typical challenges of Big Data, which are required to be solved. As a part of this research twenty experts from different industries and academies of Finland were interviewed.

Ausserhofer, J., Gutounig, R., & Oppermann, M. (2015, October). News Production Workflows in Data-driven, Algorithmic Journalism: A Systematic Literature Review. Presented at the Dubrovnik Media Days, Dubrovnik. In the past decade, the “experimental use of algorithms, data and social science methods” (Gynnild, 2014, p. 715) in journalism has been growing rapidly. What was known as Computer-assisted reporting and database journalism and what was mainly employed by election analysts, weather reporters, and investigative journalists in the United States (Cox, 2000), is today important for many more practitioners in all kinds of newsrooms and departments all over the world. Data-driven journalism has become a key theme in journalism education, in the public discourse about journalism, and in journalism research. But in what way have journalistic workflows and routines actually changed due to the broad introduction of data in the newsroom? How has this impacted journalistic norms and ethics, and the skills requirements for journalists? Based on a systematic review of scholarly papers and industry reports this paper develops a comprehensive conceptual model for newsroom processes in datadriven journalism. It discusses regional differences, the background and epistemology of data journalists, and enabling and hindering factors of data-driven news projects. In the conclusion, the article identifies gaps in the research landscape that are fruitful for future investigations. -- Cox, M. (2000). The Development of ComputerAssisted Reporting.
