At our company, we are trying to do something very similar to SOMs (but with a different interface) for Medline and other extremely large databases. The funny thing is that we run the process on the results of the queries (on the fly) and we have optimized performance to such a degree that Medline queries return faster than in normal Medline. Generally in under 2 seconds and sometimes only a few milliseconds. All of this on a PC running Linux. We utilize the concepts that human indexers put in their articles and we have also developed an effective automated indexer (currently working for Medline.) We call the project ConceptBrowser and the tool which will include knowledge management and collaboration components will be called ScienceLine. Go to our site and register to be informed when you can start using it during the beta period. So, your dream is definitely close to reality. We are also developing other technologies to correlate articles based on their references (backward and forward) and their usage. Keep an eye on us as we roll out these tools for the biotech and pharma institutions and if you would like to be more involved, let me know. We are doing a lot of these things out of our deep love with digital library technology and it is always nice to talk with people who are excited about the same things. -- Georgios Papadopoulos ------------------------------------------------------------- Atypon Systems voice: (408) 988-1240=09 3312 Woodward Ave fax: (408) 988-1070 Santa Clara, CA 95054 efax: (603) 761-5213 http://www.atypon.com pcs: (650) 906-7516 .
