Researchers at institutions in developing countries submit a query through the TEK search engine, which is emailed directly to MIT. The TEK Server searches the web, locates pages, selects which pages to send back, compresses them, and returns them back to the user. Because the search results are returned asynchronously, by email, the connectivity charges are lower, addressing the common low bandwidth concerns experienced in developing countries.
Elsevier's Scirus search engine will add to the TEK project by providing access to the scientific subset of the web. As part of "Search Scirus with TEK," Scirus will enable researchers to retrieve only the most accurate and relevant search results while spending minimum time online. Moving forward, Elsevier and MIT researchers will expand their collaboration to include institutions with specific expertise in information provision to developing countries in order to move the project through to the deployment phase.
"Search Scirus with TEK" can help bridge the information divide between technologically advanced and developing countries, serving the global scientific community at large," said Sharon Mombru, Senior Product Manager of Scirus. "Scirus' involvement in the TEK project also builds on Elsevier's ongoing commitment to delivering valuable scientific information to developing areas and bringing researchers closer to both peers and individual research communities."
"We are excited to collaborate with Elsevier to offer a robust, user-friendly and valuable service to researchers across the globe," said Saman Amarasinghe, Associate Professor of Electrical Engineering and Computer Science at MIT. "Elsevier brings years of experience in organizing and retrieving information, and understands the needs and constraints of end-users. We hope that organizations with access to users in these countries will take Elsevier's lead and get involved in "Search Scirus with TEK" to help put this initiative into practice and extend the reach of valuable scientific information available on the Internet."
For the past five years, researchers at MIT's Computer Science and Artificial Intelligence Laboratory have been developing an alternate model of Web access called TEK. The TEK system empowers users in developing countries by providing a full Interent experience using cheap email accounts to transfer all information. TEK stands for "Time Equals Knowledge", as users "pay" to access information with "time" needed to transmit queries and results via email. TEK offers significant economic savings, as email accounts can be up to 10 times cheaper than full Internet access in many low-connectivity areas. To further minimize connection charges, the TEK Server performs specialized filtering and compression, and keeps track of the pages sent to each user to avoid wasting bandwidth on duplicate content. On the client side, downloaded content is available for offline viewing and indexing using a standard Web browser. The TEK effort is part of a larger goal to develop novel technologies that are specifically designed to meet the economic and social constraints of the developing world. http://tek.
