Abstract
This session will discuss various approaches to searching the localised ‘deep Web’ from optimising for Google, through metadata harvesting to dynamic distributed queries, with examples from ongoing work at The Natural History Museum. The goal of this work is simply to reduce the number of times users need to type in a query to return all relevent, accurate online resources.
The session will cover:
- Optimising your site and databases for a Google/Yahoo search – The Dino Directory
- Data harvesting to provide a ‘gateway’ – the Data Locator.
- Z39 what? Pragmatic approaches to joining up data sources.
- Dynamic queries to many databases – the Global Searcher.
- OAI, web services, and the advantages of dynamic data harvesting.
