Many user queries nowadays contain references to named entities, which has motivated the development of new methods that exploit entity semantics for query expansion. At the same time, Wikipedia has been widely recognized as a large network of named entities, where entity-related articles are organized into a comprehensive hierarchy of categories and present summarized information on these enti...

Anytime algorithms exchange execution time for quality of results [8]. Anytime algorithms can be executed in two modes: either by being given a contract time (a set amount of time to execute), or an interruptible method. To improve the solution, anytime algorithms can be continued after they have halted. Instead of correctness, an anytime algorithm returns a result with a “quality measure” whic...

This papers proposes a new approximation method for Dempster-Shafer belief functions. The method is based on a new concept of incomplete belief potentials. It allows to compute simultaneously lower and upper bounds for belief and plausibility. Furthermore, it can be used for a resource-bounded propagation scheme, in which the user determines in advance the maximal time available for the computa...

Radio communications via channels already occupied by conventional telecommunication systems can be established only by Ultra-WideBand (UWB) radio where the spectrum of transmitted signal covers an ultra-wide frequency band. The power spectral density (psd) of transmitted UWB signal is extremely low and does not cause any noticeable interference in the conventional telecommunication systems. Th...

3-D reconstruction in Nuclear Medicine imaging using complete Monte-Carlo simulation of trajectories usually requires high computing power. We are currently developing a Parisian Evolution Strategy in order to reduce the computing cost of reconstruction without degrading the quality of results. Our approach derives from the Fly algorithm which proved successful on real-time stereo image sequenc...

Fractional derivatives are applied in the reconstruction, from a single observable, of the dynamics of a Duffing oscillator and a two-well experiment. The fractional derivatives of time series data are obtained in the frequency domain. The derivative fraction is evaluated using the average mutual information between the observable and its fractional derivative. The ability of this reconstructio...

In Big data era, information integration often requires abundant data extracted from massive data sources. Due to a large number of data sources, data source selection plays a crucial role in information integration, since it is costly and even impossible to access all data sources. Data Source selection should consider both efficiency and effectiveness issues. For efficiency, the approach shou...

This paper describes a real-time decision-making model that combines the expressiveness and exibility of knowledge-based systems with the real-time advantages of anytime algorithms. Anytime algorithms ooer a simple means by which an intelligent system can trade oo computation time for quality of results. Previous attempts to develop knowledge-based anytime algorithms failed to produce consisten...

The Data-as-a-Service (DaaS) model enables data analytics providers to provision and offer data assets to their consumers. To achieve quality of results for the data assets, we need to enable DaaS elasticity by trading off quality and cost of resource usage. However, most of the current work on DaaS is focused on infrastructure elasticity, such as scaling in/out data nodes and virtual machines ...

Effective authoring aids, whether for novice, secondlanguage, or experienced writers, require linguistic knowledge. With respect to depth of analysis, authoring aids that aim to support revising and editing go beyond POS-tagging but cannot work on complete, mostly well-formed sentences to perform deep syntactic analysis, since a text undergoing revision is in a constant state of flux. In order ...
