Members of a community may not know each other in real life. The design of CVE in which members are known and there is interaction in a real space is different to the traditional design of CVE. It should consider the real location of each resource, appropriated awareness and communication strategies, and the human-human and human-resource relations. Our university department was selected as an example organizational unit for experimentation. We start with the real physical environment and we design a CVE to provide new collaboration features to people working in the unit and those who will visit it. The advantages of the approach are many. First, people are familiar with the basic physical environment. Second, some activities requiring physical presence can be done with virtual presence, enabling more convenient ways to work for employees. Third, new opportunities for collaborative work appear as it is easy to do them with the proposed CVE. Finally, the approach is extensible, since new features can be added. We present the approach and the design of the proposed CVE.","PeriodicalId":376743,"journal":{"name":"Proceedings of the IEEE/LEOS 3rd International Conference on Numerical Simulation of Semiconductor Optoelectronic Devices (IEEE Cat.

Fundamental to the design of SharpSpider is the publication of an API for use by other services on the network.

The second method uses shingles concept to obtain the similarity measure for every document pairs, and each shingle from the original document is inserted in a hash table, where shingles of each candidate document are searched. Given an original document and some candidates, two methods find documents that have some similarity relationship with the original document. Experimental results were obtained by using a plagiarized documents generator system, from 900 documents collected from the Web. Considering the arithmetic average of the absolute differences between the expected and obtained similarity, the algorithm that uses shingles obtained a performance of 4.13% and the algorithm that uses Patricia tree a performance of 7.50%.","PeriodicalId":376743,"journal":{"name":"Proceedings of the IEEE/LEOS 3rd International Conference on Numerical Simulation of Semiconductor Optoelectronic Devices (IEEE Cat.

We present a hyperlink analysis model, based on modelling the Web graph as an absorbing Markov chain, that can be employed for both authority and utility analysis of documents. The results of experiments for both types of hyperlink analysis underpin the importance of making this distinction. In addition, we provide evidence that support the investigation of more elaborate hyperlink analysis methods on a query-by-query basis.","PeriodicalId":376743,"journal":{"name":"Proceedings of the IEEE/LEOS 3rd International Conference on Numerical Simulation of Semiconductor Optoelectronic Devices (IEEE Cat.

Although parents believe that having the Internet at home is important to their children's success in school, evidence linking access to success is lacking. In the HomeNetToo project we automatically recorded the actual Internet use of 130 children (mean age=13) from low-income families for 16 months. Most of the children were African American (83%) and male (58%), and all resided in a mid-size urban community in the United States. Results indicated that Internet use predicted both grade point averages (GPAs) and standardized test scores. In general, the more frequently children used the Internet at home, the better their GPAs and standardized test scores. Implications for efforts to reduce the digital divide and facilitate access to technology for all children are discussed.","PeriodicalId":376743,"journal":{"name":"Proceedings of the IEEE/LEOS 3rd International Conference on Numerical Simulation of Semiconductor Optoelectronic Devices (IEEE Cat.
