Logical reasoning in real time on multiple, heterogeneous, gigantic and inevitably noisy data streams in order to support the decision process of extremely large numbers of concurrent users users.
Challenges, Approaches, and Solutions in Stream Reasoning PDF Print

Hereafter you can see the presentation I gave at Semantic Days 2012 about Stream Reasoning. The main goal of the presentation is to give the most up to comprehensive view on Stream Reasoning.

Unanswered Questions PDF Print

“Is a traffic jam going to happen in this highway? And is then convenient to reallocate travelers based upon the forecast?” “By looking at the click stream coming from a given IP, can we notice the shifts of interest of the person behind the computer?” “Which contents of the news Web portal are attracting more attention? Which navigation pattern would lead readers to other news related to those contents?” “Are trends in medical records indicative of any new disease spreading in given parts of the world?” “Where are all my friends meeting?”  “In the financial context, can we detect any intraday correlation clusters among stock exchange?”  Although the information is often available, there’s no software system capable of computing the answers - indeed, no system enables users even to issue such queries.

An Unexplored, yet High Impact, Research Area PDF Print
We hereby propose stream reasoning - an unexplored, yet high impact, research area - as the new multi-disciplinary approach which will provide the abstractions, foundations, methods, and tools required to integrate data streams and reasoning systems, thus giving answer to the above and innumerable other questions. The idea is simple, yet pervasive. Starting from lesson learned in the database community (e.g., the ability to efficiently abstract and aggregate information out of multiple, high-throughput streams) a new foundational theory of stream reasoning is needed, capable to associate reasoning tasks to time windows describing data validity and to therefore to produce time-varying inferences. From these foundations, new paradigms for knowledge representation and query languages design must be derived, and the consequent computational frameworks for stream reasoning oriented software architectures and their instrumentation must be deployed.
