Information retrieval systems with database-selection aids
First Claim
1. An information retrieval system comprising:
- a plurality of databases; and
a server for providing client access to the plurality of databases, wherein the server includes;
database-selection means for enabling a user to select one of a first or a second set of categories, with each of the first set of categories associated with a subset of the plurality of databases and each of the second set of categories associated with a respective set of interactive control features for requesting additional category-specific information from the user;
database-navigation means for providing a user-navigable directory of at least a subset of the plurality of databases, with the directory including;
one or more beginning, intermediate, and terminal nodes, with each intermediate node associated with at least one of the beginning nodes and one or more of the terminal nodes, and each terminal node associated with a subset of the plurality of databases or a subset of corresponding database profiles; and
one or more sets of interactive control features, with each set of control features associated with a corresponding one of the intermediate nodes for enabling the user to query a set of databases including databases associated with each terminal node that is associated with the one of the intermediate nodes; and
database-discovery means for receiving a user-defined query, for executing the received query against a profile database including profiles of one or more of the plurality of databases, and for identifying one or more databases from the plurality of databases based on computed relevance of the corresponding profiles to the received query and according to a ranking of the profiles having the corresponding computed relevance based on a jurisdictional lexical analysis, wherein the query includes a plurality of terms, wherein the computed relevance includes a bias based on geographic, jurisdictional, or generic terms in the query.

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.

7. An information retrieval system comprising:
-
a plurality of databases; and a server including a memory that contains instructions that are readable by a processor and cause the processor to; receive a restricted natural language search request; receive a current navigation position within a user-navigable database directory; and execute the search request against a metadata-based profile for each of a plurality of databases within the user-navigable database directory contingent on the current navigation position within the user-navigable database directory so as to search a current database associated with the current navigation position and any subdirectory database associated with the current database. - View Dependent Claims (8, 9, 10, 11)

12. An information retrieval system comprising:
-
a plurality of databases; a profile database that includes profiles of the plurality of databases; and a server for providing client access to the plurality of databases, wherein the server includes; database-discovery means for;
receiving a user-defined query having one or more terms, executing the user-defined query against the profile database to identify one or more relevant databases based on a corresponding computed relevance and according to a ranking of the profiles having the corresponding computed relevance based on a jurisdictional lexical analysis, and providing the one or more relevant databases of the plurality of databases to a client access device for display. - View Dependent Claims (13)
