The realization of Semantic Web vision is based on the creation and use of semantic web content which needs software tools both for semantic web developers and end users. Over the past few years, semantic web software tools like ontology editors and triple storage systems have emerged and are growing in maturity with time. While working on a large triple dataset during the course of a research aiming at a lifelong "semantic" repository of personal information, besides other semantic web tools, we used several RDF browsing and visualization tools for analyzing our data. This analysis included ensuring the correctness of the data, conformance of instance data to the ontology, finding patterns and trails in the data, cross-checking and evaluating inferred data, etc. We found that many of the features needed by a metadata creator and analyst are missing from these tools. This paper presents an investigation of the tools that are used for browsing and visualizing the datasets. It first identifies the browsing and visualization features required by a semantic web developer and a metadata creator and analyst and then based on these features evaluates the most common RDF browsing and visualization tools available till date. We conclude this paper with recommendations for requirements to be fulfilled for future semantic web browsing and visualization.
Adaptive support weight (ASW) strategies in local stereo matching have recently attracted many researchers due to their compelling results. In this paper, we present an evaluation study that focuses on weight computat...

The Bebras International Contest on Informatics and Computer Literacy is a motivation competition in informatics that addresses all lower and upper secondary school pupils divided into three age groups: Benjamin (age 11-14), Junior (age 15-16) and Senior (for upper secondary level). Using a computer the pupils have to solve 15 to 21 tasks of different levels within 45 minutes. Two general types of problems have been used: interactive tasks and multiple-choice tasks. Creating interesting and attractive tasks that are also motivating and funny for the pupils is very challenging. The paper deals with criteria for good tasks. Some examples of tasks are presented and discussed as well.
