Abstract
Some information retrieval systems, such as the Westlaw™ system, empower users to search thousands of databases. One problem with some systems is that the large number of databases makes it difficult for some users to identify the right database(s) to search. Thus, the inventors devised, among other things, new options for helping users target searches on the right databases. One option enables users to search sample-based database profiles. Another enables users to navigate to a category or subcategory in an online database directory and search databases or database profiles associated with the category. And, yet another enables users to select a query-category and receive a list of relevant database choices, a list of links into a database directory, or a sequence of follow-up questions. One or more of these or other disclosed innovations enable users to execute more effective search strategies, while potentially reducing computational burdens on information retrieval systems.
