Contextual Computing - Knowledge Graphs & Web of Entities

Filtering From the Firehose: Real Time Social Media Streaming

Cloud Elements

Traditional security tools like security information and event managers (SIEMs) are struggling to keep up with the terabytes of event data (250M to 2B events) being generated each day from an ever-growing number of devices. Cybersecurity has become a data problem, and enterprises need to reply with scalable solutions to enable effective hunting and combat evolving attacks. Rethinking the cybersecurity problem as a data-centric problem led Accenture Labs’s Cybersecurity team to use emerging big data tools along with new approaches such as graph databases and analysis to exploit the connected nature of the data to its advantage. Joshua Patterson, Michael Wendt, and Keith Kraus explain how Accenture Labs’s Cybersecurity team is using Apache Kafka, Spark, and Flink to stream data into Blazegraph and Datastax Graph to accelerate cyber defense. Leveraging Datastax Graph and Blazegraph allows Accenture Labs to greatly accelerate query and analysis performance compared to traditional security tools like SIEM. Josh, Michael, and Keith share the challenges of fitting cybersecurity data into each of the graph structures, as well as the ways they exploited the connectedness of events to discover new threats that would have been missed in traditional SIEM tools. In addition, they explain how they use GPUs to accelerate graph analysis by using Blazegraph DASL. Josh, Michael, and Keith end by demonstrating how to efficiently and effectively stream data into these graph databases using best-in-breed technologies such as Apache Kafka, Spark, and Flink and touch on why Kudu is becoming an integral part of Accenture’s technology stack. Utilizing these technologies, clients have supercharged their security analysts’ cyber-hunting abilities and are uncovering threats faster.

There was a time when the Enterprise Data Warehouse (EDW) was the only way to provide a 360-degree analytical view of the business. In recent years many organizations have deployed disparate analytics alternatives to the EDW, including: cloud data warehouses, machine learning frameworks, graph databases, geospatial tools, and other technologies. Often these new deployments have resulted in the creation of analytical silos that are too complex to integrate, seriously limiting global insights and innovation. Join guest speaker, 451 Research’s Jim Curtis and Pivotal’s Jacque Istok for an interactive discussion about some of the overarching trends affecting the data warehousing market, as well as how to build a next generation data platform to accelerate business innovation. During this webinar you will learn: - The significance of a multi-cloud, infrastructure-agnostic analytics - What is working and what isn’t, when it comes to analytics integration - The importance of seamlessly integrating all your analytics in one platform - How to innovate faster, taking advantage of open source and agile software Speakers: James Curtis, Senior Analyst, Data Platforms & Analytics, 451 Research & Jacque Istok, Head of Data, Pivotal

Analytical Innovation: How to Build the Next Generation Data Platform

VMware Tanzu

Over the last few years we have observed the emergence of hybrid human-machine information systems which are able to both scale over large amount of data as well as to maintain high-quality data processing intrinsic in human intelligence. In this talk I will focus on the use of human intelligence at scale by means of crowdsourcing to deal with Big Data problems. We will look specifically on how to deal with the variety in data by means of Human Computation still being able to operate with a large data volume. First, I will introduce the area of micro-task crowdsourcing also providing an overview of different research challenges that needs to be tackled to enable large-scale hybrid human-machine information systems. Next, I will provide examples of such hybrid systems for entity linking and disambiguation using crowdsourcing and a graph of linked entities as background corpus. I will describe how keyword query understanding can be crowdsourced to build search engines that can answer rare complex queries. Finally, I will present new techniques that allow to improve the quality of crowdsourced information system components by means of push crowdsourcing.

“The Semantic Web is not a separate Web but an extension of the current one, in which information is given well-defined meaning, better enabling computers and people to work in cooperation.” - this statement of Tim Berners-Lee has gained even more relevance since the start of this century. The humanity is rapidly developing and persistently experiencing local and global challenges, such as global warming/climate change, dis-balances in demand and supply, among many others. Mastering most (if not all) of them require a behavior change. Behavioral change is difficult to achieve per se, and it is important that technology – as a major enabler - has a positive rather than a negative impact here. Further, the dramatic growth of data volumes (Big Data, Internet of Things) and the data’s increased power and impact and on the people's daily lives are calling for new types, practices and policies of behavior with data. These factors made the role of semantic technology even more crucial: in terms of providing a well-defined meaning, and eventually delivering Smart Data for a functional and fair data value chain. Addressing the behavioural change with Smart Data, I discuss potential ICT solutions investigating the domain of energy efficient buildings. Particularly, our completed OpenFridge experiment will be presented: design and development of the Internet of Things data system with semantic and data analytics enablers for building new services on a top of typical home appliance data — in particular, refrigerators. The system has been evaluated with real life end-user pilots. In conclusions, I overview our related ongoing work, namely, in the areas of the impact of Big Data on society and related research roadmapping (linking to sociology), personalized energy efficiency data management services in buildings (linking to psychology), and semantic data licensing (linking to law).

This slide deck has been prepared for a workshop on Linked Data Publishing and Semantic Processing using the Redlink platform (http://redlink.co). The workshop delivered at the Department of Information Engineering, Computer Science and Mathematics at Università degli Studi dell'Aquila aimed at providing a general understanding of Semantic Web Technologies and how these can be used in real world use cases such as Salzburgerland Tourismus. A brief introduction has been also included on MICO (Media in Context) a European Union part-funded research project to provide cross-media analysis solutions for online multimedia producers.

On day-to-day basis, she manages a complex ecosystem of data providers, data users, regulators and funders and has been advising digital and data strategies with governments and development partners that set the foundations for the Digital Transformation in SSA. Under her leadership, DDI has been supporting the Ministry of Health in Uganda, in partnership with UNICEF and Rockefeller Foundation, to better understand the impact of the COVID19 pandemic on the continuity of essential health services (CEHS) at national and sub-national levels using public health data. As part of the project, the team has set up a governance structure and a technical infrastructure, which enabled the development of a CEHS app that fosters a data-driven culture in maintenance of CEHS within the Division of Health Information an MoH and its partners. She has also led the launch of AIDA, the Action Insights Data platform in Uganda, which was developed in partnership with the United Nations Capital Development Fund (UNCDF) and the Belgian Government. The goal of the Platform is, first, to accelerate the use of private and public data sources for better decision making and, second, to create an entire data ecosystem for the country, while complying to regulations and ensuring privacy. Rositsa was recently named one of Forbes’ 30 Under 30 Social entrepreneurs in Europe.
