Scientific insight is not linear. But what are the driving factors of your own research that accelerate your insights? Insights follow a complex process—they require an oscillation between theoretical reflection, generally in terms of a model or a theory, and contemplation of the empirical evidence, in an optimal case leading to a specification or extension of your theoretical bases.
But what if there is accumulating evidence that your underlying model no longer holds? Often it is difficult for us to see this, as it requires from us to take a different frame of mind, to step away from our typical interpretation frame. Also, it needs a lot of evidence in order to form an understandable pattern. Thus, it needs the combined effort of a scientific community to identify that—often implicit—assumptions hinder progress and, even more difficult, to find a way out.
This process is an important driving force in science that requires specific forms of communication. When problems with a dominating paradigm are accumulating and have caused already a certain number of members of the community to collaboratively think about alternatives, communication can follow traditional lines, i.e. a scientific publication in form of a position or discussion paper. In this journal this would be a Technical Contribution.
Before this stage, discussions among different researchers with different perspectives and access to different kinds of methods and data are necessary to find better ways of formulating and generalizing the underlying critical factors. This can be a difficult but highly productive and insightful process that needs to be framed in a discourse format that makes the purpose of this discussion clear. In this journal we therefore offer the category Discussion, which optimally features opposing perspectives. Often, scientists are reluctant to offer too pronounced opinions because they are, by definition, attackable. Yet, such opinions are very valuable as they will advance the common understanding of certain problematic issues. We therefore strongly encourage submissions to the Discussion section.
One very important market place of opinions are conferences. Conferences are hubs of scientific exchange, where apart from their objectively evaluated research results, people communicate their insights. Sometimes, also insights that have not yet reached sufficient maturity for publication are communicated, albeit in a more information fashion; in an oral presentation one may dare to mention ones suspicions of the underlying model’s problematic aspects upon request, in a paper one might not want to, because there is just not enough evidence and foundation from the results. Thus, conferences contain—and possibly produce—information that goes beyond what is reported in the papers. However, there are barely non-transient formats that allow to capture such impressions. In this journal we offer the category Conference Reports. In a Conference Report you have the freedom to give your subjective version of the—possibly underlying—opinions encountered in the presentations and the non-informal discussions. Also, you are encouraged to provide any kind of evaluation you deem insightful: were there really new approaches or rather small deltas with well-known methods? Have new challenges been identified? Conference Reports are places of possibly quite subjective evaluations of conferences, and therefore highly valuable to the whole community.
Therefore, if you are intrigued by certain and recurring shortcomings of a dominating paradigm, or if you feel there are converging threads of discussion at a conference, take the time and use one of the above categories to express your observations—this journal provides you with the space for your opinion!

1 Forthcoming Special Issues
1.1 Smart Environments
Smart Environments aim to provide installations that support and enhance the abilities of humans in their regular life and possibly improve the environments themselves too, e.g., in terms of energy efficiency. Smart Environments are based on complex and distributed technical systems but they bear more challenges than the seamless composition of its components addressed in current research in technical disciplines. Setting technical challenges aside, providing intuitive interfaces to a system hidden in the environment and identifying means that allow the system automatically to provide suitable assistance for a wide range of every-day tasks involves several research questions.
How can a ubiquitous system communicate its state of believe to a human?
How can Smart Environments quickly comprehend a situation and user needs?
How can a system adapt to users and how adaptive should it be?
Which forms of knowledge representation help to form a shared mental model of system and user?
How can user acceptance be measured efficiently and reliably?
What are social and ethical implications of Smart Environments?
Which are the most pressing use cases? What are their specific requirements?

1.3 Algorithmic Challenges and Opportunities of Big Data
Computer systems pervade all parts of human activity and acquire, process, and exchange data at a rapidly increasing pace. As a consequence, we live in a big data world where information is accumulating at an exponential rate and complexity, and often the real problem has shifted from collecting enough data to dealing with its impetuous growth and abundance when going through it to mine relevant or pertinent information. In fact, we often face poor scale-up behaviour from algorithms that have been designed based on models of computation that are no longer realistic for big data. This implies challenges like algorithmic exploitation of parallelism (multicores, GPUs, parallel and distributed systems, etc.), handling external and outsourced memory as well as memory-hierarchies (clouds, distributed storage systems, hard-disks, flash-memory, etc.), dealing with large scale dynamic data updates and streams, compressing and processing compressed data, approximation and online processing respectively mining under resource constraints, increasing the robustness of computations (e.g., concerning data faults, inaccuracies, or attacks) or reducing the consumption of energy by algorithmic measures and learning. Only then big data will truly open up unprecedented opportunities for both scientific discoveries and commercial exploitation in Artificial Intelligence, Geoscience, Social Web, Finance, e-Commerce, Health Care, Environment and Climate, Physics and Astronomy, Chemistry, Agriculture, Life Sciences and Digital Libraries, among other domains.
The aim of the special issue is to collect overview articles on important state-of-the-art algorithmic foundations and applications, as well as articles on emerging trends for the future of big data.
