The demonstration is showing a mobile application (2-player game), utilizing context-awareness relying on agents. The agents are gathering and processing context-data retrieved from the device’s built-in sensors, which will be distributed within the system. The application (game) adapts to certain changes in the environment (in the demo: connectivity, power supply) to preserve the mobile device...

We consider the image interpolation problem where, given an image v with uniformly-sampled pixels vm,n and point spread function h, the goal is to find a function u(x, y) satisfying vm,n = (h ∗ u)(m,n) for all m,n ∈ Z (1) so that u approximates the underlying function from which v was sampled. This article improves upon the IPOL article “Image Interpolation with Contour Stencils” [7]. In the pr...

The semi-structured nature of Semantic Web data and its use of multiple vocabularies make it challenging to describe the structure of some RDF dataset. When trying to understand the content behind some SPARQL endpoint, users usually need to write a number of SPARQL queries to “mine” the types contained in the dataset and their relations. We argue that this is a tedious, error-prone and time con...

When searching for an arbitrary subject in weblogs or archives, users often don’t get the information they are really looking for, because they are overwhelmed with an overflow of information while sometimes the presented information is too scarce to make any use of it. Without further knowledge about the context or background of the intended subject users are easily frustrated because they eit...

In this tutorial, attendees will learn how to architect safely extensible component systems. The tutorial introduces to the concepts of component-oriented programming before presenting and explaining compound documents as an application example of extensible component systems. Creation of an add-on component to this system will be demonstrated. Finally, architecting for safe extension will be d...

This demonstration shows how accelerometers and buttonpress loggers embedded in a television remote control can be used to distinguish different participants based on the unique way each person wields the remote. This is a live demonstration of the inference technology presented in the paper Inferring Identity using Accelerometers in Television Remote Controls, which appears as a full paper in ...

Until very recently, most NLP tasks (e.g., parsing, tagging, etc.) have been confined to a very limited number of languages, the so-called majority languages. Now, as the field moves into the era of developing tools for Resource Poor Languages (RPLs)—a vast majority of the world’s 7,000 languages are resource poor—the discipline is confronted not only with the algorithmic challenges of limited ...

Polarized topics often spark discussion and debate on social media. Recent studies have shown that polarized debates have a specific clustered structure in the endorsement network, which indicates that users direct their endorsements mostly to ideas they already agree with. Understanding these polarized discussions and exposing social media users to content that broadens their views is of param...

“Push Technology” stands for the ability to transfer information as a reaction to event occurrence. This demonstration proposal describes Amit, a middleware framework that resolves a major problem in this area: the gap that exists between events that are reported by various channels, and the actual cases in which the user needs to react to, hereby called; reactive situations. These situations a...

Data-driven systems for natural language processing have the advantage that they can easily be ported to any language or domain for which appropriate training data can be found. However, many data-driven systems require careful tuning in order to achieve optimal performance, which may require specialized knowledge of the system. We present MaltOptimizer, a tool developed to facilitate optimizat...
