The fast-growing Web 2.0 applications promote explicit social structure and explosive data on the Web, and enable the realization of social webtops, where users use web applications to collaboratively organize and share online data. In this work, we show that semantic wiki technologies are suitable for building a social webtop. We also identify two key issues in realizing social webtop applicat...

There are several semantic sources that can be found in the Web that are either explicit, e.g. Wikipedia, or implicit, e.g. derived from Web usage data. Most of them are related to user generated content (UGC) or what is called today the Web 2.0. In this talk we show several applications of mining the wisdom of crowds behind UGC to improve search. We will show live demos to nd relations in the ...

The ever increasing demands of data intensive eScience applications have pushed the limits of computer networks. With the launch of the new 40 Gigabit Ethernet(40GE) standard, 802.3ba, applications can go beyond the common 10 Gigabit/s per data stream barrier for both local area, and as demonstrated in the GLIF 2010 and Supercomputing 2010 demos[3], wide area setups. In this article we profile ...

In addition to creating demonstrations for differential geometry, we also use and develop the software to investigate mathematics problems. In one major application, we used the program to investigate critical point behavior in polyhedral catastrophe theory. One advantage to developing and using our own software to do this is that we want to show demos of what we find. This means that the softw...

Witnessing the richness of data in document content and many ad-hoc efforts for finding such data, we propose a Data-oriented Content Query System (DoCQS), which is oriented towards fine granularity data of all types by searching directly into document content. DoCQS uses the relational model as the underlying data model, and offers a powerful and flexible Content Query Language (CQL) to adapt ...

In this paper I discuss the implementation of a lattice-gas simulation on a hexagonal grid. The application is written in the C++ language using the Windows and DirectX APIs. Due to the nature of the project, following the initial introduction to the lattice gas concept, the discussion has somewhat the feel of a software manual. After documenting my application in Section 3, I spend some time d...

This article frames the problematic explored in Special Issue, namely, Maghreb and North Africa's ‘crisis of democratization.' Across cases, crisis is multi-layered, involving first, counter-revolution since 2011 (and 2019) uprisings revolutions; second, breakup states, particularly those mired violence (e.g. Libya); third, setbacks even among states that have to an extent transcended democrati...

While individual components for semantic data integration are commonly available, end-to-end solutions are rare. We demonstrate DataOps, a seamless Anything-to-RDF semantic data integration toolkit. DataOps supports the integration of both semantic and non-semantic data from an extensible host of different formats. Setting up data sources end-to-end works in three steps: (1) accessing the data ...
