> I believe you are talking about information *indexing* service, > not "information *retrieval* service" DRIS will build the information retrieval infrastructure for Internet, but not the final search engines. Many intelligent search systems can apply DRIS as their data source and provide high quality of personal search service. > DRIS is only a design. > When you say "build", who will do it? How does it get paid? > (i.e. What is the incentive for anyone to do this?) I have mentioned in our paper, DRIS will improve the performance of Internet search engine in recency, coverage and so on, but this can't ensure the establishment of DRIS. The architecture of DRIS is organization level-sub country Internet level-country level-whole Internet level. DRIS will first solve some urgent problems in the bottom level, then to the top level. Just in our testbed, CERNET (China education and research network), few universities have the web search engine for the school network. Further more, most university has many characteristic information resources such as Ftp, BBS and special databases in library, but almost no a university has union search system that can efficient integrate all these resources. To find the comprehensive, we always have to search in many search interfaces one by one. It's the problem in organization level. Then there still no an efficient to share these resources among different universities. It's the problem in sub Internet level. These all bring the request for creating the underlying structure of DRIS. Solving some urgent problems of his own and then benefiting others may be the real guarantee for the success of DRIS. Who control the DRIS?It's administrated by none of us but every of us. DRIS is managed by its users and coordinated by a public organization, just like management method of DNS. Every organization is its customer and also its builder and manager. It's just the real truth of Internet. DRIS is a public opening system, which needn't any profits from its users and of course need not any advertisements and Spam of company. > I had a quick look of your first paper. > - It seems to suggest that each DNS domain has a central authority, > which may not be the case > - It is unclear to me DNS domains are the right unit for indexing > webs, as opposed to topical areas. Current search engines all managed by corresponding company. This is the centralized management method. This method is not suitable to manage the information on Internet. Now there are billions of web pages, millions of databases and many other kinds of information resources on Internet. Search engines will encounter many bottleneck problems when the size of its database reaches some critical values. In fact, just as a web pages search engine, it can't continue to index close to the entire Web as it grows. Now the update interval of most pages database is almost one month. We can also obtain information from different special databases like IEEE's digital library, FTP, P2P, etc. Could you image single private company can efficiently administer all these information resources? Every search engines try to provide the comprehensive and fresh information for its users, but none of them would build a database system that can mirror the whole Internet. So a distributed management frame may be more appropriate for Internet. As our experience, decentralized management is much more effective than absolutely centralized administration in a large-scale system. By this means, the key issue is how to divide the Internet correctly. We found there has been an available division method on Internet, domain name system (DNS). DNS is a hierarchical distributed system. All the web site on Internet is efficiently managed in this system. The basic architecture of DNS is also an organization level-sub country internet level-country level. We just apply its basic idea to DRIS, but not strictly comply it. > > bottomline: yes the current google domination is not sustainable, however > the basis of DRIS design raises its own problems. Although I can't say DRIS is better than Google at now, but it can surely meet some demands that Google can't fill. In fact,DRIS will build a system than can integrate all kinds of resources, but not only web pages. The first testbed of DRIS on CERNET will be finished in 2004 fall. Practice is the only principle to judge a theory. More discussion is also very important for a new system.
