Title: Big Graph Processing Systems
Abstract: Graphs are data model abstractions that are becoming pervasive in several real-life applications and use cases. In these settings, users primarily focus on entities and their relationships, further enhanced with multiple labels and properties to form the so-called property graphs. Modern big graph processing systems need to keep pace with the increasing fundamental requirements of these applications and to tackle unforeseen challenges. Motivated by our community-wide vision on future graph processing systems, in this talk I will present the system challenges that are lying behind big graph processing and analytics research areas. Many current graph query engines only support subsets of graph queries that they can efficiently evaluate, thus disregarding more expressive query fragments on top of property graphs. It becomes crucial to address efficient query evaluation for complex graph queries, as well the extensibility of the underlying graph query and constraint languages and the support of property graph schemas. Moreover, the dynamic aspects of query evaluation on streaming graphs are equally important components of big graph ecosystems and require design and benchmarking efforts. During the talk, I intend to touch upon our work on these topics and to pinpoint the research directions and open problems for big graph processing systems.

Title: Following the rules: From Policies to Norms
Abstract: Since its inception, the world wide web has evolved from a medium for information dissemination, to a general information and communication technology that supports economic and societal interaction and collaboration across the globe. Existing web-based applications range from e-commerce and e-government services, to various media and social networking platforms, many of whom incorporate software agents, such as bots and digital assistants. However, the original semantic web vision, whereby machine readable web data could be automatically actioned upon by intelligent software web agents, has yet to be realised. In this talk, we will show how rules, in the form of policies and norms, can be used to specify a variety of data usage constraints (access policies, licenses, privacy preferences, regulatory constraints), in a manner that supports automated enforcement or compliance checking. Additionally, we discuss how, when taken together, policies, preferences, and norms can be used to afford humans more control and transparency with respect to individual and collaborating agents. Finally, we will highlight several open challenges and opportunities.
