Systems, methods, and interfaces for reducing executions of overly broad user queries
View Patent ↗The present inventor devised, among other things, an exemplary information retrieval system that promises to reduce the execution of overly broad queries. One exemplary system detects overly broad queries and presents users one or more potentially relevant portions of a hierarchical subject matter classification system, instead of executing the query against the targeted database. The system also presents users the option of accessing one or more relevant documents to the query via an interface for the classification system.
1. A computer-implemented method for reducing execution of overly broad user queries, the method comprising the steps of:
providing a database containing information organized into classes according to a subject matter classification system;
building a hierarchical subject guide relating to a class of information within the subject matter classification system, the hierarchical subject guide including a plurality of topic levels;
categorizing each of the topic levels relating to the specific class of information as either overbroad, broad, or narrow;
receiving a query from an access device having a display;
mapping the received query to one or more of the topic levels and designating the query as either overbroad, broad, or narrow without executing the query against the database;
displaying a portion of the hierarchical subject guide that corresponds to the topic level to which the query has been mapped without executing the query against the database when the query is designated as either overbroad or broad, wherein the portion of the hierarchical subject guide that corresponds to the topic level is displayed together with a plurality of document identifiers, wherein each document identifier is linked to one of the plurality of documents related to the topic level; and
executing the query against the database and displaying the results when the query is designated as narrow
wherein each of the above steps are carried out using a computer.
2. The method of claim 1 , wherein the step of displaying a portion of the hierarchical subject guide includes displaying a user-selectable topic level indicator as well as a plurality of user-selectable sub-topic level indicators.
3. The method of claim 2 , further comprising displaying a first set of document identifiers associated with a first sub-topic level indicator when a user selects the first sub-topic indicator and displaying a second set of document identifiers associated with a second sub-topic level indicator when a user selects the second sub-topic level indicator.
4. The method of claim 1 , wherein displaying at least a portion of the hierarchical subject guide includes displaying first and second user selectable subject matter identifier and respective first and second document count indicators, wherein selection of one of the first and second subject matter identifiers causes display of one or more document identifiers associated with the one of the first and second subject matter identifiers.
5. The method of claim 1 , wherein displaying at least a portion of the hierarchical subject guide includes displaying a subject matter identifier and a document count indicator.
6. An information retrieval system comprising:
a search module running on a server and interfacing with a database;
an access device including a graphical user interface in communication with the search module to receive queries from a user and present search results to the user;
a subject guide module having a classification data set descriptive of the contents of the database;
a search-assistance module in communication with the subject guide module and configured to categorize each level of the classification data set as either overly broad, broad, or narrow, and configured to categorize a user query as either overly broad, broad, or narrow, without executing the query against the database;
a query definition region forming part of the graphical user interface;
a hierarchical subject matter guide region forming part of the graphical user interface, the hierarchical subject matter guide region including a broad topic level display area configured to display a user selectable broad subject matter identifier and corresponding document count indicator that indicates the corresponding number of documents in the database associated with the selectable subject matter identifier, the hierarchical subject matter guide region also including a narrow level topic display area configured to display a plurality of selectable narrow subject matter identifiers and corresponding document count indicators, wherein the narrow subject matter identifiers correspond to subtopics of the broad subject identifier; and
a document identifier display region forming part of the graphical user interface and configured to be displayed simultaneously with the hierarchical subject matter guide and the query definition region, wherein the document display region simultaneously displays one or more user selectable document identifiers in response to selection of one of the broad subject matter identifier and the narrow subject matter identifiers, wherein each user selectable document identifiers is selectable to invoke retrieval of a corresponding document related by subject matter to the subject matter identifiers.
7. The information retrieval system of claim 6 , wherein the query definition region is operably coupled to the search assistance module, wherein the search assistance module activates display of the hierarchical subject matter guide region in response to a determination that the query is too broad.
