This week, David Hawking's article Web Search Engines Parts 1 & 2 presumed way too much background knowledge. I tried my very best to follow it, but he used too much nomenclature without defining those terms. However, it gave me a general idea of what happens -- crawling and indexing -- each time I enter a search into an engine.
My most favorite articles by far were Shreeves' Current Developments and Future Trends for the OAI Protocol for Metadata Harvesting and Bergman's White Paper - The Deep Web: Surfacing Hidden Value. I am so glad that most repositories seem to be implementing the OAI Protocol as a general standard! This will vastly improve findability and put libraries on the same page as each other. I hope that the OAI Registry will help libraries see which resources other libraries have already digitized, so that other libraries have no need to spend tons of money to digitize them again. This will help prevent redundancy.
The description of BrightPlanet's functions fascinated me -- really, a search engine that could capture dynamically generated sites??!! This sounds very powerful. I wanted to dry this out, but when I went to BrightPlanet's site, unfortunately, it seemed that one had to subscribe to this content. Might anyone know how to get in touch with them for a free trial?
